802.11 a

[sarahr202]

Hi everybody

My book says following about 802.11a frequency ranges.

5.15-5.25 GHz   Indoor use

5.25-- 5.35 GHz  In door and outdoor use

5.725- 5.825 Ghz   outdoor use

Are the above ranges merely recommendation or they are mandatory part of 802.11a?

thanks and have a great week

The reason for the outdoor notation regarding the 5.25-5.35 and 5.725-5.825 GHz is that FCC limited power is higher. 5.725-5.825 (U-NII-3) allows for max power of 1W, 5.25-5.35 (U-NII-2) allows for max power of 250mW.

Thanks Blakekrone

My question is since 802.11 uses license free frequency ranges then whom should we contact if someone is not abiding by 802.11 standard for example one can simply uses higher power than allowed by 802.11 standard in such case one can completely disables near by wlan deployment ?

If you are in the US you would report to the FCC.

Even If we are using Free license frequency range ?

Sara,

Correct even if its free license. Think of the FCC as a traffic cop. If free license was OPEN for anyone to do anything with, think of all the loud radios vendor could develope and stomp all over other devices in the process in the free license space.

Ghostbusters.  You call the Ghostbusters.

Seriously, do you think the FCC, a Federal Government Agency, filled with red-tape, take a complaint form (two sets in triplicate) about someone possibly misusing the 802.11a frequency?

Maybe not.
