[FADCA] Interesting Observation

Tue, 17 Dec 2002 07:46:54 -0500

Interesting, these devices are FH rather than DS
the data rates are 1,2, and 3 mbit data rates, it
changes speed by changing the number of bits/symbol
At 1 mb it is a regular GFSK signal to obtain higher
speeds they go to multiple bits/ symbol and that is
multi level FSK from what I can see. Not real barn
burners speed wise but they will punch data through
better than the DS devices. Also would keep the regular
802.11 folks off of them.
