RE: REGS/ RE: stds-802-16-tg4: Re: 5GHz Fixed Wireless Access in danger!
Colleagues,
Please focus on the subject of the e-mail you are referring to: The subject
is the NPRM to improve the sharing possibilities in part 15.247 on one hand
and to permit higher data rates in the same rules.
Note that the group did not get a chance to study the remark in the FNPRM
regarding the rules in the U-NII band.
The document gives a report of what the group came-up with.
If you want to contribute to that group's thought process, please provide
input to the regs reflector as soon as possible, so we can look at the
merits of your proposals.
Thanks

> 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.
