David,
I think that before working on NPRM,
we should have an agreed 802 strategy regarding the 5GHz band splitting
between different working groups. I see the UNII FCC regulations as a good
base for doing that, based on the limitations of the transmitted power.
The 802.16 interests are related to high level transmitted power, the 802.11
and 802.15 want to limit it at lower level.
It is clear that in the near future FCC will unify ISM and UNII regulations
in 5GHz, so we should already consider this consolidation and have an
agreement based on BW splitting. This will not preclude the lower power
systems to work in the higher bands, for example indoor . Nevertheless,
the focus of the higher bands should be the Fixed Wireless Access.
I would like to see in that band more waivers for P-MP, sectorized
antenna systems.
Lets discuss this in the next teleconference. I will be happy to join.
Please send me the bridge number.
Marianna

Marianna,
There will be another conference call to discuss this NPRM on June 22, 2001,
7-9 AM PDT. We can discuss the issues with Vic at that time.
Regards,
David

Dear Roger,
For clarification, the FCC notice 01-158, makes no distinction
between indoor/outdoor installations. OFDM falls in the class of
"digital modulation system".
All the systems in 5GHz ISM band are "1Watt", for more than 700KHz BW
direct sequence, in case of the old rules.
My interpretation of the text in the teleconf is:
- digital modulation systems are limited to a power density
under 10dBm/MHz and a transmitted power under 100mW;
- outdoor and P-P systems are allowed to transmit 1W, according
to the old rules, meaning no more than 8dBm/3kHz, while keeping
the processing gain rule - being DIRECT SEQUENCE
(not OFDM!) systems.
I will be the first to be happy if my interpretation was wrong.
