Description
TUTORIAL IEEE802WIRELESS meeting session at IETF97
2016/11/13 1230
A
Well,
it's
almost
time
to
begin
I'll
just
say
a
couple
things
before
really
getting
started.
First
of
all,
lesser
I
probably
will
become
obvious
I'm,
not
the
originator
of
the
material
on
the
slides
and
so
there's
three
presentations
and
I
just
sent
them
to
take
Karen
and
she'll
post
them
on
an
ITF
website.
Presumably
any
minute
now
and
but
these
presentations
are,
the
two
large
presentations
are
actually
taken
from
stuff,
that's
already
publicly
available
from
my
Tripoli
website.
A
So
that's
one
thing
see:
oh
I
guess
it's
time
to
get
started
well
before
I
forget
if
I
say
something
that
doesn't
make
sense
or
if
you
want
more
information
about
anything
particular
we
only
have
an
hour,
but
I'll
do
my
best
to
make
a
short
answer
now
and
you
can
see
my
email
address
up
there
and
on
average
I'll
respond,
so
please
I
don't
hesitate
to
send
email
and
if
I
don't
know
the
answer,
I
will
I'll
find
it
for
you.
So
welcome
to
the
wireless
tutorial
802
wireless.
A
This
is
a
nub
date
from
februari
presentation
and
I
have
been
assured.
There
would
be
a
good
idea
for
me
to
read
this
to
you.
I
didn't
write
this
at
lecture
symposia
seminars
or
educational
courses.
An
individual,
for
instance,
me
presenting
information
on
not
Tripoli
standard,
shall
make
it
clear
that
his
or
her
views
should
be
considered
the
personal
views
of
that
individual,
rather
than
the
formal
position,
explanation
or
interpretation
of
that
Tripoli,
and
so
that's
way
more
formal
than
I,
usually
a.m.
A
Well,
there's
a
lot
of
rigmarole
about
that
typically
I.
If
I
trip
Lee
wants
to
make
a
formal
position
navel
to
another
body,
for
instance,
idea
they'll
establish
a
liaison
and
then
the
liaison
statements
will
be
vetted
by
various
standing
committees.
On
over
couple
in
an
itrip,
Lyon
802
wireless,
then
people
make
an
honest
effort
to
make
the
statements
say
what
I
Tripoli
said
that
on
you
know
things
that
should
say,
and
then
it's
sent,
but
only
after
review
by
the
wide
community
I.
A
But
overall
I'll
try
to
explain
to
you
why
stuff
is
interesting
and
where
it
fits
and
I
Triple
E
and
then
again,
if
I
don't
know
an
answer
to
your
question.
I
can
find
out.
I
started
going
to
80
two,
but
six
years
ago
was
involved
with
80
to
21,
which
is
a
more
or
less
an
interface
group
between
III
TF
and
an
802.
A
Lately
I've
been
involved
with
Internet
of
Things
technical
materials
in
this
largely
in
802
dot.
15
also
I've,
been
involved
with
only
ran
in
a
standing
committee
for
IETF
on
Moran
is
I
believed
when
I
have
a
presentation
here
in
int
area
sometime
this
week,
I
think
I,
don't
remember.
Maybe
JC
Zuniga's
going
to
do
that.
Anyway,
all
these
documents-
and
it's
all
freely
available-
you
can
see
the
URL
there
on
mentor
whenever
I
type
Emmy
on
my
computer
I
go
to
MIT
org
and
it's
all
there.
It's
usually
pretty
interesting
stuff.
A
The
802
dot11
material
is
here
from
she
Dorothy
Stanley
created
as
she
unfortunately
couldn't
be
here
today,
because
getting
from
San
Antonio
on
Friday
to
Seoul
South
Korea
on
sunday
is
beyond
the
airline's
capability.
It
seems
so
I
cut
out
all
the
sessions
on
Friday
and
flew
over
here
to
be
here
today
and
she'll,
be
here
tomorrow
in
some
frame
of
mind
and
she's
also
going
to
be
available
to
answer
questions
Bob
highly
I
believe
will
also
be
here
in
Seoul.
He's
the
chair
of
a
talk
about
15.
A
So
practically
all
of
this
material
is
going
to
be
updates
just
from
a
tour
2011
and
a
tour
to
dot
15
there's
other
interesting
groups
in
802.
So
here's
an
overall
diagram,
eight,
oh
two
dot
one
is
a
very
interesting
area.
Well
as
it's
sort
of
the
switch
protocols
and
so
on,
and
wireless
LAN
is
a
tour
2011
it
had
15
over
here
is
why
they
call
it
wireless
specialty
networks
now
used
to
be
personal
area
networks,
and
then
you
can
see,
there's
several
others
dot
16
used
to
be
all
wimax.
A
Lately,
they've
been
doing
some
other
interesting
things.
Coexistence
has
to
do
with
things
like
how
does
dot
15
interact
with
11?
How
do
we
interact
with
the
3gpp
and
so
on
and
in
there's?
Just
24
is
a
good
place
to
get
white
papers.
For
instance,
they
have
some
IOT
stuff
and
actually
I
can't
remember
lately
what
they've
been
doing
and
nothing?
Oh,
how
did
that
happen?.
A
Working
group,
for
instance,
is
11,
which
corresponds
to
an
area
in
IETF,
standing
committees
and
task
groups.
Standing
committee
is
doesn't
have
the
same
kind
delivery
schedule
as
a
task
group.
They
can
be
monitoring
or
produce
new
work
items
as
needed,
but
the
task
group
is
really
working
towards
them
according
to
a
schedule
with
a
well-defined
deliverable
and
then
there's
study
groups
which
can
be
considered
a
precursor
to
a
task
group
and
the
task
groups
I've
been
involved
with
it.
A
A
So
what's
happening.
Is
that
Dorothy
gave
me
a
really
a
lot
of
slides
and
there's
no
way
I
could
cover
them
all
so
I'm
going
to
not
cover
them
all
and
I.
Just
put
these
in
the
presentation,
so
you'd
know
which
ones
I
was
going
to
cover
if
you
download
it
from
from
the
ITF
website.
Ok,
so
this
is
a
by
the
way
up
here
you
can
see
the
sort
of
canonical
form.
This
is
a
a
tour
2011
document
and
it
shows
that
is
2016,
and
this
is
document
number
500
release
one.
A
A
So
so
that's
enough
of
mentor
for
now
and
we
go
back
to
Dorothy's
presentation,
so
this
she's
just
a
description
of
what
I'm
going
to
be
telling
you
about,
and
so
this
is
actually
an
update
from
a
presentation
it
was
made
earlier
in
February,
and
that
was
a
very
big
update
from
a
previous
presentation
made
by
Donald
eastlake
and
so
all
of
those
slides
are
sort
of
batched
together
in
Dorothy's
presentation.
Oh,
you
went
to
fullscreen.
A
Thank
you
for
please,
don't
hesitate
to
tell
me
I
stove,
because
I'm
I'm
trying
to
figure
it
all
out
here,
okay,
so
so
these
things
are
still
auld
up
there
and
you
can
download
this
presentation
in
its
entirety,
but
I'm
only
going
to
go
through
part
of
it.
So
they'll
update
part
of
this.
It
has
to
do
with
them
what's
happening
since
some
since
februari,
and
we
have
this
sub
gigahertz
slide
is
basically
done.
That's
I
can't
give
you
very
much
in
material
about
that.
The
fast
initial
authentication
is
I.
Think
of
some
interest.
A
Yeah,
let
me
go
to
this
slide
just
for
a
minute.
So
what
happens
in
dot
11
is
that
you
start
with
this
Wireless
and
not
guess
the
next
generation,
but
anyway,
this
is
where
people
come
in
with
proposals
on
technical
work.
That
has
to
be
done
and
so
then
some
some
of
its
actually
constituted
in
the
study
groups
and
interest
groups
and
then
some
of
that
progresses
into
actual
task
groups
with
deliverables.
A
And
then
the
task
groups
work
away
for
a
while
until
they
can
come
over
the
specification
and
then
the
working
group
votes
on
it
or
comes
up
with
comments
and
when
I
say
come
up
with
comments.
I'm
not
kidding.
Some
of
them
have
like
a
thousand
500
comments
and
every
last
one
of
those
comments
has
to
be
resolved
and
they're
usually
perceptive
in
some
way.
A
So
and
then,
once
you
get
through
with
the
working
group,
which
remember
is
like
I
Triple
E
area
director,
then
it
actually
goes
into
the
standards
Association,
which
is
our
sponsor
and
that
broads
it
makes
it
brought
much
broader
community
for
input
not
just
80
to
wireless
but
the
entire
standards
organization,
and
then
they
finally
get
published.
Well,
what
I
was
going
to
say
about
the
revision
project?
Is
these
amendments
it
boils
down
to?
A
Is
you
have
a
tude
11,
which
happened
a
long
time
ago
and
even
before,
then,
as
you
know,
it's
been
around
for
almost
20
years
and
then
amendments
get
made
that
makes
serious
changes
to
the
evolution
of
the
standard
and
people
can't
find
all
that
stuff
very
easily.
So
the
roll
up
or
the
revision
actually
puts
all
the
amendments
into
a
single
document,
and
this
one
for
Don
11
just
is
some
it's
published.
So
it
includes
these
ones
here,
for
instance,
TV,
wyd,
space
and
so
on.
A
Ac
gives
you
I,
guess:
I
think
that
they
provide
data
rates
up
to
7,
gigahertz
actually
or
bits
per
second,
and
so
it's
it's
some
interesting
stuff.
Well,
anyway,
back
to
where
I
was
in
addition.
Okay,
so
I
talked
about
these
and
then
new
activities
is
this
wake
up.
Radio
Task
Group,
which
I
think
is
super
important,
and
it
grew
out
of
this
a
long
range
low
power
not
to
remember
to
mention
the
toes
interest
groups
and
done
11.
A
So
that
was
a
successful
effort
and
they
have
now
on
a
project
to
make
an
amendment
for
that.
There's
also
a
topic
interest
group
on
live
communications,
so
something
about
life
I
hear
which
I
personally
think
is
a
terrific
new
area.
Just
well
we're
going
to
that's
going
to
make
a
huge
impact
and
then
there's
a
lot
of
interest
in
discussions
about
them.
A
Interaction
between
11
and
3,
gpp
and
I'll
have
more
to
say
about
that
later.
All
right,
so
I'll
women
make
sure
yeah.
So
this
wake
up
radio
again
I've
only
got
another,
maybe
at
most
20
minutes
to
talk
about
dot11.
So
I
can't
go
into
very
much
detail
at
all,
but
one
way
you
can
really
save
a
lot
of
battery
consumption.
B
A
This
I
turn
the
device
off
and
then
naturally,
if
you
do
that,
you
have
to
have
a
way
to
wake
it
up.
So
you
can
see
how
Dorothy
has
organized
its
information
to
show
the
use
cases
in
the
parameters
for
the
technology,
and
here
since
you
have
now,
if
you
go
in
and
get
this
document
which
will
be
on
the
ITF
web
page
or
from
mentor,
you
will
be
able
to
follow
these
links
to
get
all
the
interesting
technical
stuff.
By
the
way,
I
should
say
one
little
thing
about
standards,
organization
and
I,
Triple
E.
A
They
require
two
documents:
one
is
project
authorization
and
it's
called
a
par,
and
so
you
had
to
basically
they're
not
going
to
approve
your
project
unless
you
can
tell
them
what
you're
going
to
do
so.
This
is
the
recipe
for
the
deliverables
for
this
wake
up
radio
and
then
not
only
you're
going
to
have
to
tell
them
what
you're
doing
and
what
you're
going
to
live,
or
you
have
to
tell
them
why
in
the
heck
you're
doing
it,
and
so
basically
this
boils
down
to
what
is
the
commercial
advantage
of
this
technology?
A
A
Some
of
these
are
actually
completed
like,
for
instance,
the
fast
initial
link
set
up
a
I
as
completed
and
the
revision
is
completed,
so
this
list
could
be
considered
to
be
shorter,
but
I
don't
want
to
go
through
each
one
of
these
in
specifics,
I
already
showed
you
this
picture,
but
I
want
to
now
at
least
emphasize
that
some
of
these
are
I,
think
more
important
or
more
interesting
to
ITF
folks
than
others.
So,
for
instance,
this
high
efficiency,
wireless
ATT,
dot11
ax-
this
is,
you
might
say,
will
become
essentially
next
generation
from
AC.
A
An
AC
is
the
one
that
has
high
multi-gigabit
data
rates,
and
so
a
8
11
ax
is
just
a
huge,
huge
effort.
There's
hundreds
of
people
in
every
single
meeting
and
that
translates
into
dozens
and
dozens
of
technical
proposals
and
arguments
and
I
don't
go
because
I
MnDOT
15,
but
I
stop
by
every
once
in
a
while
and
this
one
over
here.
This
fast
initial
link
setup
you
can
see.
11
AI
is
already
in
sponsor
ballot,
which
means
that
the
working
group
has
done
done.
A
Okay,
other
than
those
things
there's
some.
We
have
some
known
areas
of
mutual
interest
between
I,
Triple,
E
and
I.
Tf1
is
at
this
internet-draft
trying
to
describe
use
cases
for,
and
problems
with,
multicast,
so
multicast
is
crucial
for
deployment
of
ipv6
and
yet
multicast
has
numerous
issues
with
80
2011,
specifically
and
in
even
worse
issues
related
to
about
15
in
a
way
so
fell.
In
the
one
hand,
you
have
a
fabulous
technology
ipv6.
On
the
other
hand,
everybody
wants
to
run
it
over
wireless
and
the
multicast
stuff
has
got
essentially
got
bugs.
A
There's
a
couple
of
things:
I,
don't
know
much
about
Dan
Harkins
has
some
privacy
tools,
opportunistic
wireless
encryption
and
assaulted,
password
thing
so
I
think
those
are
probably
pretty
straightforward
things
to
read
about
and
then
there's
also
some
ongoing
work
with
cap
way
up.
Cap
is
cat
way
up
still
active
I,
don't
I,
don't
think
half
pipe
is
meeting,
but
anyway
people
use
it
for
dot11
stuff.
A
So
that's
the
end
of
what
Dorothy
said
was
updated
since
februari,
but
I
had
a
couple
of
other
things.
I
wanted
to
emphasize
from
the
other,
slides
and
I'm
just
going
to
go
directly
to
them
again,
and
this
will
be
on
the
ITF
website
and
it's
already
I'll
mentor.
You
can
go
get
it
I'm
not
just
show
this
picture
anyway.
So
we
had
this
body
area
network
and
then
around.
That
is
pan.
This
is
a
talk
about
15,
stuff
and
other
a
case.
A
I
don't
mention
it,
but
later
doc,
15
is
shipping
a
million
devices
a
day.
So
it's
a
pretty
good
choice
for
IOT
stuff.
Then
we
have
a
2011
dot.
16
which
used
to
have
wimax
tenant
was
considered
a
metropolitan
area
network,
and
then
we
have
TV
wyd
space
stuff
out
and
regional
area
networks
is
so
called
and
I
wish
I
had
a
glass
of
water
I'll
get
one
shortly.
B
A
All
this
it'll
be
a
miracle
okay.
So
anyway,
you
can
see
from
these
pictures
that
Wi-Fi
is
really
caring.
Most
of
the
world's
wireless
data
and
unfortunately
I
I-
think
maybe
one
of
these
is
2014
and
other
ones.
You
know
before
that,
and
it's
also
from
the
UK,
so
you
can't
absolutely
guarantee
that
the
same
happens
here
but
I'd
be
willing
to
bet
that
in
the
u.s.
it's
even
more
pronounced.
So
what
that
means
that
Wi-Fi
is
really
really
really
important.
A
There's
a
Wi-Fi
Alliance,
which
I
can't
tell
you
very
much
about,
but
there's
a
pretty
I,
think
a
great
amount
of
corporation
between
80
to
wireless
and
the
Wi-Fi
Alliance,
and
on
Tripoli
doesn't
do
any
certification
or
anything
like
that
and,
in
fact,
I
think
Wi-Fi
Alliance.
You
might
consider
to
do
more
of
the
system's
level
stuff
instead
of
I
Triple
E.
A
A
A
C
A
Then
you
can
go
to
either
dot11
or
dot
15,
and
so,
for
instance,
here
if
I
go
to
dot,
11
and
I,
think
Dorothy's
presentation
is
500.
So
let's
just
go
500
by
golly
there.
It
is
okay,
yeah
all
right,
so
this
is
just
this
is
more
technical
than
I
probably
would
get
anywhere
else
in
this
presentation.
But
the
idea
was
that
when
your
view
and
get
into
it,
oh.
A
And
you
know
this
is
so
many
moving
parts
here
from
current
slide.
Okay,
so
it's
a
Leyden,
11
I,
I,
that
this
is
the
fast
initial
link
setup
thing
they
were
faced
with
this
problem.
You
go
over
here
and,
if
you're,
using
an
authentication
from
what
then
existing
82
dot11,
you
had
all
these
protocol
steps.
Well,
you
know
how
long
that
takes
I
mean
it's
aggravating
right,
and
so
it's
good
enough
to
long
enough
time
to
drop
lots
of
packets
and
so
on,
so
they
spend.
A
While
figuring
out
how
to
make
it
better
and
now
I
don't
know
if
this
is,
for
instance,
beat
we
can
probe
response
is
probably
two
messages
at
least,
and
here
we
hopefully
don't
have
to
more
than
two
authentication
messages,
but
anyway
diagrammatically.
It
looks
a
lot
better
and
they've
also
allowed
for
public
key
and
shared
key
variations.
A
So
here's
a
X-
this
is
sort
of
the
you
might
say
the
next
generation
of
attitude
11ac,
although
it's
not
exactly
a
linear
thing,
but
the
point
is
that
everybody
expects
that
ax
will
be
on
the
future
specification
that
allows
extremely
high
data
rate
applications,
so
so
focus
on
dis
deployments.
Now.
This
is
actually
a
very
important
point
because
for
one
thing,
if
you
have
a
lot
of
people
in
an
apartment,
complex,
that's
a
disappointment
for
the
thing.
A
If
you
have
a
lot
of
enterprises
on
a
crowded
Street,
that's
a
lot
of
deployments,
and
so
what
it
boils
down
to
is
you
have
to
do
something
to
try
to
avoid
interference
between
all
these
sub
access
networks
that
are
separately
managed
and,
for
example,
one
thing
that
there
I
believe
we're
going
to
do.
I
don't
know
if
the
current
status
is,
but
they
were
going
to
deprecate
82
dot,
11
a-11,
be
just
for
the
simple
reason
that
B
takes
up
too
much
time
on
the
air
and
it
crowds
out
new
standards
like
11
ax.
A
So
anyway,
as
with
all
new
technologies
has
got
to
be
faster
and
low
delay
and
more
efficient
and
better
power,
consumption
and
everything
else
you
can
think
of,
but
I
think
they're
making
an
honest
effort.
Now,
I'm
not
a
five-person
physical
layer
person,
but
when
I
see
1024
QAM,
I
think
that's
pretty
hot.
That
means
they
can
get
a
lot
of
bits
per
hertz
of
bandwidth,
and
so
I
don't
know
how
many
bits
you
get
out
of
there's
a
quadrature
amplitude
modulation
and
besides
that
they
have
multi-user,
MIMO
and
other
things.
A
So
that
means
that
you
can
have
pretty
high
efficiency
and
accuracy
and
extracting
your
bits
and
you
can
get
a
lot
of
bits
per
Hertz.
So
this
is
really
gonna
notice.
It's
going
to
be
fabulous
so
so
this
is
0
they
talked
about.
Also,
if
you
are
able
to
do
some
sort
of
management
between
your
base
stations,
then
you
can
do
have
special
reuse.
So
you
can
see
here.
If
I,
you
have,
let's
say
seven
different
frequency
bands
in
your
and
that
you're
allowed
to
allocate.
A
Then
you
can
have
a
pretty
high
spatial
reuse
in
this
way
and
I
wanted
to
emphasize
this
slide
just
for
a
moment,
so
the
way
that
an
X
I'm
going
to
be
honest,
this
is
slightly
beyond
my
understanding.
I
couldn't
tell
you
exactly
how
these
things
were.
The
frequency
bands
were,
but
I
can
I
know
what
this
means.
A
You
know
the
orthogonal
frequency-division
multiplexing
and
what
it
boils
down
to
is
that
you
have
I
think
these
are
no
time
slots
in
and
you
can
get
these
frequencies
and
so
on,
but
you
have
bid
/
per
slot.
It
all
belongs
to
one
user,
but
now
you
can
actually
slice
it
up
and
have
them
in
this
way
they
are
able
to
do
two
more
users
into
the
same
amount
of
a
spectrum
in
time
slot.
A
Okay,
so
that's
an
example
of
ax
and
doing
37
yeah
I
12
at
least
mention
the
802
dot11
a.
Why?
Because
here
they're
talking
about
20
gigabits
per
second
at
the
access
point,
it
is
high
high
spectral
bands,
but
well
I.
Think
20
yoga
bits
per
second
is
pretty
cool
and
so
I
think
we
have
a
lot
to
look
forward
to
their
showing
a
pictures
here.
You
know
buses
and
so
on
and
and
well.
A
Okay.
So
there's
that
for
you-
and
this
is
an
interesting
picture-
it
shows
it
the
same
mac
layer
in
80.
2011
is
able
to
serve
about
11
a
and
B
and
G,
and
in
and
you
know,
we've
been
using
these
ones
here
for
a
long
time.
Ac
is
coming
in
and
ax
is
in
process.
So
all
these
things
effectively
can
be
used
without
too
much
problem
from
the
IP,
but
it
uses
the
same
device
driver
in
many
respects.
So
this
is
a
good
situation.
A
You
can
pick
out
which
physical
layer
option
you
want
and
not
have
to
change
your
your
network
layer,
software
and
I
want
to
come
back
to
this
idea
a
little
bit
later.
Tion
yeah,
okay,
so
now
for
something
completely
different.
I
just
wanted
to
mention
something
about
not
nineteen,
because
when
you
have
the
situation
where
unlicensed
band
is
carrying,
the
heavy
majority
of
the
world's
data
and
3gpp
is
collecting
the
majority
of
the
world's
wireless
revenue.
A
Then
something
is
eventually
going
to
happen
there
and
what's
happening
is
or
something
called
laa,
but
I
forgot
exactly
what
it
stands
for,
but
it
stands
for
it.
What
it
means
is
that
LTE
and
83
at
eleven
are
both
planning
to
use
unlicensed
ban
or
license
exempt
spectrum,
and
they
could
crowd
each
other
out.
So
there
needs
to
be
a
way
for
LTE,
folks
and
Tripoli
folks
to
co-exist
and
let
the
user
use,
whichever
one
is
best
for
their
needs.
A
A
C
A
A
Okay,
so
you
mentioned
briefly
before
about
the
topic
of
multicast,
and
we
have
some
performance
optimization
things
and
we
have
this
draft
also
with
them.
Well,
there's
a
draft
with
Mike
McBride
from
pim
and
there's
a
draft
that
I've
been
involved
with
with
the
on
Dorothy
and
JC
and
Dan
Harkins
so
on.
A
Ok,
so
additional
topics
of
mutual
interest
on
just
briefly
honors
wide
space,
there's
ahora
si
on
providing
access
to
the
wide
space,
databases
and
I
Tripoli
at
80
to
dot
22
and
a
lot
to
do
with
the
white
space
stuff
mentioned
before.
There's
the
ongoing
work
with
cap
web
and
in
a
2
2011
uses
iono
registries
to
define
parameters
for
it.
A
A
A
A
Alright,
so
this
is
a
slide
step
from
Bob
highly
he's
the
chair
of
82
dot
15
and
has
some
other
affiliations
as
well
and
I
have
his
email
address
up
later,
but
you
can
send
any
question
stage
or
Bob
or
maybe
about
this
and
I've
already
made
this
disclaimer.
So
I
will
just
remake
the
disclaimer
okay.
So
here's
the
same
picture
just
shows
a
2
2
dot
15
in
its
home
position
with
80
to
wireless
organization,
and
it
has
a
before
remember:
802
dot11
had
about
300
and
let's
say
seventy
voting
members
well.
A
Dot
15
only
has
about
a
hundred
and
something
maybe
around
100,
but
but
in
many
ways
two
groups
are
run
a
similar
but
they're
not
absolutely
the
same.
But
there's
a
lot
of
similar
are
these
okay?
Oh
one
thing
I
should
have
mentioned
before.
I.
Remember,
I
mentioned
a
little
bit
about
well,
for
instance
in
this.
If
you
have
a
document
or
specification,
then
the
task
group
first
of
all
get
a
document.
That's
ready
for
presentation
to
the
working
group,
and
the
working
group
in
our
case
is
82
that
15,
for
instance.
A
One
task
group
recently
finished
was
a
layer,
2
routing,
and
so
then
that
15
makes
comments
on
it
and
then,
after
that's
done
it
sent
up
to
our
sponsor
and
our
sponsor
is
at
the
next
higher
level
of
this
organizational
chart,
which
is
80
to
local
and
metropolitan
area
networks.
Lms
see
which,
if
you
remember
that
thing
on
mentor,
is
one
of
them
document
subdivisions
on
mentor,
which
leads
you
to
a
tour
2011
about
15,
so
sponsor
is
in
a
way
providing
the
legitimacy
for
the
standardization
effort.
A
Okay,
so
here's
the
scope
and
purpose
of
80
to
15
activities
focused
on
wearable
devices
to
start
off,
which
were
personal
area
networks
or
pans,
and
but
that's
been,
it's
really
outgrown
that
a
lot
and
it's
really
attending
much
more
towards
I,
guess,
process,
control
and
IOT
sort
of
things.
So
the
data
rates
are
a
wide
wide
range
of
data
rates
and
long-range
communications
and
100
megahertz.
A
hundred
terahertz,
okay,
well
I'm,
not
aware
of
anything
at
eight
hundred
terahertz
and
then
to
ask
Bob
about
that.
A
But
it's
anyway
a
wide
range,
yeah
I
guess
so
there
is
an
optical,
no
owc
optical
wireless
communication
effort.
There
good
point,
thank
you,
okay,
so
they
stopped
focusing
directly
on
personal
area
networks,
but
specialty
networks
and
I'm,
not
sure
exactly
what
that
word
is
supposed
to
mean,
but
it
probably
means
whatever.
This
is
not
some
not
wireless
LAN,
so
well,
typically
short-range
communications
and
bob
says
if
it's
not
land
man
ran
or
wind,
and
it's
probably
80
to
about
15
and
there's
one
distinguishing
characteristics
will
all
show
a
little
bit
more
about
this
later.
A
It's
just
it's
a
matter
of
protocol,
just
like
IETF
works
on
protocol,
but
it's
protocol,
you
must
say
restricted,
usually
to
one
link
or
in
other
words
the
medium
between
two
neighbors.
So
so
this
is
a
crucial
thing
to
understand
about
I
Tripoli's
that
they
spend
a
lot
of
time
with
optimal
scheduling
of
the
medium
and
also
fairness.
You
want
to
have
the
medium
to
be
scheduled
fairly
so
that
all
contenders
are
allowed
to
get
on
to
that
medium
and
make
use
of
it.
A
A
Well,
they
originally
did
something
for
Bluetooth
and
then
them
people
were
using
that
for
a
while
dot
one
and
eric
erickson
was
using
it
too,
but
for
some
reason
there
was
divergence
between
80
to
15
and
Ericsson,
and
then
the
zigbee
came
along
and
did
something
else
again
so
and
again,
there's
a
strong
requirement
for
dot,
15
and
dot
11
to
interact
beneficially
and
share
the
medium.
So
that's
a
coexistence
document.
A
Dot
3
is
a
high
rate
version
of
80,
20
15,
that's
still
and
quite
active
use,
and
then
they
actually
decided
to
use
Mac
of
mac
addresses
48,
good
mac
addresses
I,
don't
know
so
one
thing
I.
It's
not
here,
but
about
dot
15
of
design
philosophy
for
a
long
time
was
we're
not
going
to
do
anything
for
you,
you're
going
to
have
to
do
all
of
that
Mac
layer
stuff
up
in
the
are
a
lot
of
things
like
interpreting
multicast
or,
are
you
might
say,
fragmentation
and
so
on?
A
All
that
stuff
has
to
be
done
outside
of
our
spec.
Well,
the
natural
result
of
that
is
that
all
these
crucial
things
that
have
to
happen
like,
for
instance,
fragmentation,
got
done
in
more
than
one
way,
and
so
now
they're
trying
to
backtrack
off
of
that
and
actually
provide
standardized
mechanisms
for
some
a
lot
of
common
things
that
have
to
be
done,
beneficially
below
below
the
layer,
3,
ok,
so
on.
They
also
go
in
the
other
direction,
low
rate
stuff
for
energy-efficient
hands
and
so
on,
and
is
always
personal
area
network.
A
So
here's
a
list
of
the
dot
for
completed
projects
dot
far
as
you
can
see,
had
been
the
center
of
a
huge
amount
of
activity.
In
not
reply
802,
they
had
ultra-wideband
Phi
of
a
special
vyas
physical
layer
in
depth
where
you
get
down
to
enabling
the
discrimination
between
noise
and
actual
bits.
And
what
is
the
modulation
technique?
That's
going
on
and
what's
the
frequency
band
and
what
is
they
even?
A
What
are
the
regulatory
requirements,
for
instance,
that
the
government
gets
in
there
and
they
can
tell
you
and
you
can
do
a
carrier
sensing
for
this
amount
of
time
or
you
have
to
well
anyway.
So
there's
a
lot
of
things
like
that
and
I
had
to
tell
you
I'm
not
aware
of
most
of
what
the
technical
content
of
these
computer
projects,
because
a
lot
of
more
done
before
I
started
coming
in
2010,
so
I
will
not
go
into
very
much
detail
on
that.
A
Well,
just
the
mission,
one
last
thing
down
here:
just
dot:
you
I
think
this
was
set
the
world
record
for
the
fastest
standardization.
They
started
like
a
year
and
a
half
ago,
and
I
only
wanted
to
do
was
to
put
in
this
band
in
India,
so
you
could
use
it
later
2015.
So
there
wasn't
much
question
about
how
to
do
them
more
completed
projects.
A
This
revision
see
sofra
802,
dot,
15,
it's
the
same
importance
we
want,
and
in
order
to
avoid
having
to
go
to
so
many
different
documents
to
good
answers,
they
roll
up
all
the
amendments.
Here
you
can
see
these
seven
different
amendments
into
the
end.
This
was
just
finished
about
a
year
ago
on
that
six
is
body
area.
Networking
I
have
not
been
involved
with
that
dot.
A
So
it
allows
you
to
do
key
management
in
multiple
various
ways.
A
tour
through
dot
1510
is
layer
to
routing
basically
mesh
under
so
and
that's
done,
but
it's
not
completely
done.
It's
just
finished
with
sponsor
ballot,
and
so
it
has
to
go
off
to
one
of
the
document
producing
agencies
within
a
toe
to
toe
with
an
802
wireless
organization.
A
Dot
3
has
a
couple
of
active
amendments.
One
is
up
at
the
terahertz
man
for
point-to-point
data
center.
Anything
with
data
center
is
important,
but
I
unfort
I,
don't
have
any
more
information
about
this.
If
I
can
find,
if
you,
if
you
want
and
then
the
high
rate
and
data
communications
also
for
here,
they
show
for
specifically
MPEG
file
transfer
so
linked
ideas.
He
show
up
the
airport
you're
in
a
hurry.
You
want
to
download
10
movies,
you
do
it
about
three
seconds
later.
A
There's
location-based
service
thing
on
that
it
seems
to
be
on
hold
I'm,
not
exactly
sure
why
there's
also
a
location
on
our
localization
effort,
n,
dot,
11,
dot,
s,
difference,
proof,
spectrum
utilization,
apparently
dude
you're,
getting
close
to
being
done.
High
data
rate,
HR,
p
they're
talking
at
the
higher
so
attitude
out,
1504
was
set
up
to
be
a
low
data
rate
and
low
power
and
on
heavily
guided
towards
them,
which
also
carried
along
with
this
design
philosophy.
A
A
Ok
so
anyway,
with
faster,
faster
and
low
rate,
actual
CPUs
and
processors,
you
can
get
a
lot
more
mileage,
and
so
we
now
have
now
had
this
other
by
a
layer
called
higher
data
rate
5,
and
it's
also
done
and
didn't
take
long
to
do
that,
one
I'm,
the
regional
sub-band
I
think
this
is
remember.
I
mentioned
about
dot
v
dot?
U,
which
is
only
for
india
well,
when
they
were
doing
the
process
for
india,
they
discovered
hey,
there's
a
lot
of
other
countries
and
event
regulatory
changes
too.
A
A
Now
I
want
to
also
point
out
that
I'm
aware
that,
probably
you
don't
care
about
a
lot
of
stuff,
but
you
have
to
know
what
I
Triple
E
is
there
to
make
these
sort
of
frequency
bands
and
five
layers
available
for
use,
and
hopefully
it
will
never
boil
up
to
something
that
really
matters
it,
the
network
layer
and
above
ok,
Oh
question.
Yes,.
A
D
C
A
C
Well,
if
I
understood
your
question
correctly,
I
think
I
can
add
something
about
that.
There
are
already
radio
devices
that
are
legal
in
one
country
that
are
not
legal
in
other
countries
and
even
80.
2011
Wi-Fi
has
this
property
that
in
Japan
I
think
channel
14
is
allowed,
but
in
the
United
States
is
not
and
most
Wi-Fi
devices,
because
they're
on
mobile
devices
in
in
the
old
days
you
could
sell
a
product
in
one
country
and
assume
it
would
never
leave
that
country.
Things
are
more
mobile
now.
C
So
now,
there's
actually
communication
with
the
access
point.
So
the
access
point
will
tell
your
phone,
which
channels
it's
allowed
to
use
based
on
the
geography
and
then
you
could
buy
an
access
point
in
Japan
and
take
it
to
the
US,
and
you
would
then
be
breaking
the
law
in
the
US
by
using
that
access
point.
So
this
is
an
issue
that
people
have
to
be
careful
of.
A
Okay,
so
dot
seven
is
it's
not
dot
11?
It's
not
da
15
Oh
women
I'm
sure,
but
it
is
not
15
and
there's
a
similar
group
in
dot
11
for
this.
But
it's
not
it's
not
82
at
15
dot
4.
So
it's
not
related
to
the
low-power
dot
dot
forward
anyway.
So
they
have
also
some
optical
wireless
communications
with
visible
light,
and
this
is
they
also
have
some
discussion
in
that
group.
I'm.
A
Not
I
haven't
been
this
group
very
much,
but
apparently
you
can
just
take
two
cameras
and
cause
them
to
be
also
communicating
packets
over
there
optical
links.
Those
then
there's
this
pier
aware,
communication,
which
I
really
don't
have
very
much
to
say
about
I,
think
it's
not
only
infrastructure
list,
but
also
I,
don't
think
that
they
have
any
sort
of
forwarding
or
hop
multi-hop
operation.
A
So
I
have
a
lot
more
to
say
about
12.
This
is
a
relatively
new
thing.
We
just
got.
We've
just
started
first
meeting
a
few
months
ago.
I
mean
our
first
meeting
is
a
task
group
before
that
there
was
an
interest
group
in
a
study
group.
So
this
is
bound
effort
here
is
to
repair
some
of
the
lack
from
80
to
about
15
from
a
long
time
ago
to
try
to
actually
provide
standardized
way
to
use
the
various
Phi
and
Mac
layer,
so
beta
2,
dot
15.
A
A
So
so
that's
the
idea
and
want
to
be
able
to
use
the
various
protocol
stacks
in
the
same
way
that
11
and
3
use
him
without
changing,
depending
upon
you
might
say,
lower
level
details,
okay,
and
we
also
want
to
maintain
backward
compatibility
with
existing
attitude
about
15
dot,
4
devices
and
applications,
plus
we're
going
to
take
layer
to
routing
and
a
campy.
This
is
ten
nine
and
from
ITF
we're
going
to
be
enabling
6lowpan
and
sixth
ish
all
in
up
with
the
same
upper
layer,
interface
work.
So
I
think
this
is
a.
A
This
is
really
interesting
word
for
ITF
and
when
we
have
a
lot
of
the
you
might
say,
yum
interest,
group
and
study
group
effort
for
you.
Li
was
done.
We
were
talking
with
folks
from
62
ish
and
six
lo,
all
along
the
way.
So
what
it
does
is
to
give
the
15
24
devices
well
I.
Think
I
already
said
this
person,
standard
interfaces
and
primitives
in
a
modular
way,
modular,
meaning
that
you
can
add
new
features
inside.
A
1512
as
people
decide
to
do
the
word,
it's
just
s,
effort
as
an
example.
You
might
want
it
to
be
that
dot.
12
does
ranging
no
matter
what
the
specific
frequency
ranges
and
so
on,
and
one
thing
that
is
going
to
be
part
of
this
is
to
use
either
type
and
The
Dispatch
ID,
so
that
we
can
package
that
come
in.
A
Okay,
so
fragmentation
is
going
to
assume.
Well
me,
we
don't
actually
have
to
specify
fragmentation
because
6lowpan
already
has
a
fragmentation
capability
and
I
do
too
dot
15
dot.
Nine
already
has
a
fragmentation
capability,
but
we
have
to
allow
it
to
all
coexist
so
that
the
higher
layers
don't
care.
That
much
and
as
mentioned,
we're
going
to
include
layer
to
routing
and
KMP
is,
as
part
of
that,
so
I've
got
seven
minutes
left
how
much
more
material
do
I
have
I
knew.
This
was
going
to
happen
and
please
I
still.
A
If
you
have
questions
even
if
I'm
not
going
to
finish
all
the
slides,
please
don't
don't
hesitate
to
stop
and
ask
so
I
have
a
picture
which
I'll
show
shortly,
but
what
we're
going
to
do?
What
we
have
is
essentially
an
architecture
to
allow
a
modular
extension
and
The
Dispatch
capability,
plus
the
interface
to
the
mac
and
phy
layers.
A
So
here's
a
picture
that's
got
way
too
much
information,
but
Pat
Kenny
insisted,
I'll,
show
it
so
I'll
try
to
parse
it
out
a
little
bit.
So
here
we're
going
to
have
v6
stuff
coming
down
and
take
them
to
keep
in
mind.
This
is
all
I
do
to
doc,
15
dot
4,
and
that
means
it
down
here.
The
mac
layer
stuff
is
15
24
and
the
file
layer,
it's
15
dot
4.
A
So,
for
example,
of
some
of
these
four
new
amendments
are
enlarging
the
ability
for
more
file
layer
to
be
included
in
them
1504.
So
this
is
a
simple
example:
we
have
v6.
My
contention
is
that
most
v6,
or
maybe
all
of
these
six
is
going
to
be
going
down
through
6lowpan
into
for
the
only
way
that
wouldn't
happen
is
it
if
people
of
princeton's
get
a
better
compression
technique
and
it's
not
standardized
6lowpan
or
something
like
that.
But
anyway,
we
have
modular
blocks
for
native
code
59,
which
is
key
management
and
then
dot1x.
A
And
this
diagram
by
the
way
is
in
flux,
and
this
is
where
we've
been
focusing
our
efforts
at
several
months:
okay!
Well,
that's
enough
for
about
12
I
have
one
more
really
important
thing
I
want
to
mention.
We
have
interest
groups
in
82
at
15,
there's
one
about
dependability.
This
is
actually
seem
to
be
picking
up
a
little
bit
of
steam.
A
recent
presentation
by
the
way
you
can
get
all
of
this
on
mentor.
A
If
you
go
into
a
row,
2
15
and
look
in
them,
there's
a
pulldown
menu
for
the
interest
groups
and
the
task
groups,
and
one
of
them
is
I
GDP,
and
so
you
can
go
get
all
the
stuff
about
this.
So
this
could
be
an
important
effort,
but
reliability.
Well,
if
you're
doing
vehicular,
for
instance,
you
kind
of
want
to
make
sure
it
actually
works.
A
High
speed
are
high
rate
rail
communications.
I.
Don't
pay
much
attention
to
that.
The
terahertz
interest
group
I
haven't
followed
that
but
low-power
wide
area
I
have
been
following,
and
here
this
is
actually
just
recently
turned
into
a
study
group.
So
I
think
it
should
be
changed
as
a
study
group.
So
low
power
wide
area
networks
are
very
interesting
for
many
applications
in
them.
Tomorrow,
blp
win
a
meeting
up
for
a
rum
in
ffort,
there's
a
new
working
group
in
IETF
for
help
you
win
and
the
prom.
A
The
thing
is
that
there's
a
lot
of
proprietary
interest
in
this
stuff
too,
and
so
we
want
to
find
out
what
our
gaps
are.
So
there's
a
lot
of
discussion
in
this
LP
wa
and
I
should
say,
study
group
about
finding
what
work,
if
any
needs
to
be
done
at
on
Tripoli
a
tour
through
wireless
area
because
of
any
gaps
and
their
existing
standards,
and
maybe
there
maybe
there
aren't
any
we'll
we'll
see
it's
not
an
effort
to
create
work.
A
It's
an
effort
to
be
responsible
to
our
our
customers,
so,
for
instance,
may
have
able
to
have
15
20,
4,
K
and
G,
which
has
already
been
done
as
part
of
a
total
of
fifteen
for
standard.
We
have
cig,
Foxin
and
Laura,
and
Etsy
has
some
efforts
and
the
3gpp
as
his
narrow
band
IOT,
and
one
of
my
things
to
do
recently
has
been
to
learn
about
this.
But
I
don't
know
anything
about
mbio
to
right
now
and
there's
also
a
low-power
group
minute
or
two
title
Evan.
A
So
let
the
on
LP
wa
will
do
is
to
we
already
have
got
scenarios
for
the
kind
of
work
that
should
be
done.
Look
at
the
channel
interference
models
and
this
you
might
consider
this
to
be
also
an
exercise
in
coexistence
and
actually
look
at
the
performance
of
what
we
have
now
so
I'm
now
down
20
minutes.
Almost
I
want.
I
have
to
mention
that
I
th
standards
standing
committee.
This
is
the
802
correspondent
or
early
months,
like
the
other
half
of
the
there's
an
ietf.
I
triple
e
group
this
meeting
here
this
week.
A
A
So
this
was
the
message
from
Karen
a
few
minutes
ago.
Do
you
want
to
provide
feedback?
Please
go
to
survey
monkey
and
express
your
opinion
and
I
specifically
want
to
ask
anybody
to
tell
what
didn't
work
about
the
presentation
and
if
you,
if
you
tell
me
it
was
too
much
material
for
an
hour.
I
will
absolutely
believe
you
and
you
can
say
which
parts
you
didn't
want
to
know
about.
A
You
know,
and
maybe
we
can
leave
some
of
that
out
or
maybe
we
can
convince
Karen
to
give
us
an
hour
and
a
half
next
time
or
something
we'll
see.
But
whatever
the
purpose
here
is
to
make
sure
the
world
you
know
working
together
and
to
make
sure
that
you
have
awareness
of
how
to
get
the
materials
that
are
of
interest
and
provide
and
again
Bob
and
me
and
Dorothy
will
be
here
this
week
to
answer
questions
and
I
do
not
at
all
mind.
