Metricom has plans for their wireless internet for all
major US cities. If you happen to be within range of
one of their poletop radios as I am, you will hear lots
of clicking on a narrow band 900 MHz radio. This includes
my 900 MHz spread spectrum cordless phone.
Also, the 2400-2483 MHz spectrum is to be used so more
interferance can be expected on this band also.
An antenna connected to a spectrum analyzer shows lots of
activity here in the San Francisco bay area on 902 to 928
Maybe if you live in a major city, you might think twice
before spending money on a 900 MHz radio.
