PAR for High Rate WPAN
I sent this Saturday but did not see in come back to me. I have included
the PAR in zipped form.
To SEC Members
The 802.15 High Rate Study Group has been a busy bunch. Since its formation
at the November,1999 Plenary, it has been working to determine the need for
a WPAN standard addressing data rates of 20 Mbits/s or more. 51 people from
roughly 30 companies have participated in the process. Attached, you will
find a draft PAR and 5 Criteria to form a Task Group within 802.15 to
develop a draft standard for a High Rate WPAN. The PAR was approved by the
Working Group at its January meeting.
Bottom line: high data rates are required for time dependant and large file
transfer applications such as video or digital still imaging. Twenty
Mbits/s is proposed to be the lowest acceptable rate for these types of
data. There appears to be a significant market, from cameras and video
webpads to games and toys, as well as significant industry interest to
support a standards activity. It should also be noted that the High Rate
Study Group has brought a significant number of new participants to 802.15.
In looking at alternatives, the Study Group determined that neither 802.11
nor 802.15.1 are able to address the key requirements of this class of
application. The basic usage model is typical of a WPAN (low power, low
cost, embeddable, range of 10 meters or less) with the exception of the
need for significantly higher speeds to support the multimedia class of
applications. Unlike the 802.11 WLAN environment, where range, link
integrity and throughput are paramount goals along with features like
roaming, a high rate WPAN optimizes for data rate, low power, low cost and
small size rather than range and link integrity. It is acceptable to move
the camera a little closer to an access point to get the "green light". It
is not acceptable to move your desk to get LAN access.
802.15.1, which is being based on the BlueToothtm specification, is great
for data and voice applications in the 1 Mbits/s range, but is not
extendable to the data rates required for video, mulitmedia, and rapid
large file transfer to and from multimedia devices.
It is not the intent of this TG to be an extension of 802.15.1, because the
MAC needs are predicted to be different. It is, however, in the best
interest of users and the industry to strive for compatibility, or at least
coexistence with these other wireless systems, especially those in
similar market spaces such as BlueToothtm . Compatibility and coexistence
criteria will be included as important considerations in the proposal
evaluations.
I would appreciate any comments you might have as soon as possible.
See you in Albuquerque--
