Re: [STDS-802-16] WiMax coverage factors



Hi all,
Thanks for the reply.
I would just to note that WiFi devices also is theorically capable to change coding scheme dynamically. That's why we could different WiFi bit rates (at least 11, 7, 5 1). Am I right?
I want to ask about some thing else: What's the most used TxPower for actual WiMax systems? Is there any implemented or theoritical propagation model so We could calculate coverage distances?
Best regrds

Tx power is the most important and fundamental factor of coverage with a same carrier.
However, Wimax coverage performance lies in its power of changing modulation
and coding scheme dynamically. Moreover, there are other techniques
such as repetition, AAS.

Hi All,
Since WiFi and WiMax could use a same Physical Modulation (OFDM) and same coding schema (BPSK, QPSK,QAM), could we say that the factor that make WiMax coverage much more greater that WiFi coverage is the Tx Power?
