<u>QUESTION FROM TimBle:

</u>"How is a Tx impound going to help?"

The 2.4GHz transmitter impound will help; here is why:

Range decreses as the number of clear channels decreases. Bandwidth drops each time FHSS encounters
a blocked frequency on a crowded spectrum. The crowded spectrum on the 2.4GHz band reduces the bandwidth,
increases the ever present background noise, increases the adjacent channel leakage ratio, reduces the range,
and causes overlapping. Overlapping is a direct interference.
Overlapping occurs only for an instant when two transmissions are on the same spot in the band and if they operate at the same bandwidth. Not all systems use the same bandwidth.
Receiver sensitivity, unique coding allows for high signal to noise ratio.
So by what factor is range reduced?
