The terminal's radio operates by "frequency hopping" spread spectrum.
The radios hop from one frequency to another very 400ms. The radio
goes through 25 different frequencies and then repeats the sequence –
all in the 902 MHz band at 150 milliwatts of power. Different
sequences define the channels. It is possible to have more than one RF
Network in the same area, providing each RF Network is on separate
channels to avoid interference and general confusion.
•
The default
Channel
is always shipped as
0
. There are 10 channels in
the USA. The Channel can be set by entering the corresponding
characters (0-9) either by scanning the bar coded Setup Menu or by
entering the character from the RF Terminal keypad.
•
All Terminals, Base Stations and Relays in the RF Network must be set
to the same channel. The channel is always displayed on the Start Up
screen when you power up the Terminal. It is possible to have more
than one RF Network in the same area, providing each RF Network is
on separate channels to avoid interference and general confusion.
