There are currently 3 "programming generations" of Atheros 802.11
wireless devices (some of these have multiple hardware implementations
but otherwise appear identical to users):
5210 supports 11a only
5211 supports both 11a and 11b
5212 supports 11a, 11b, and 11g
This paper provides incumbent wireless Internet service providers (WISPs), new WISPs and
demanding new markets (such as government and education) with a technical analysis of
alternatives for implementing last-mile wireless broadband services.
To fully utilize the available spectrum for a wireless communication
system it is feasible to adapt to different situations
on the channel. In this paper a flexible OFDM
transmitter is presented together with basic theory behind
OFDM transmission. It is shown that high flexibility can
be obtained with a reasonable amount
Flexible baseband transmitter for OFDM
of additional hardware.
Part of the design, the FFT-processor, has already
been fabricated and measurement results are presented.
