902 MHz Radio Parameter Descriptions
Parameter Explanation
Port Control Enable or disable the 902 MHz port.
Mode-Channel Sets the bit rate option. Generally, the higher the bit rate, the
lower the range of the access point. Mode-Channel defines a
frequency range that is a small portion of the available
bandwidth.
Mode-Channel displays the list of mode and channel
combinations available on the access point. Mode-Channel
options are country-dependent.
These combinations are valid in the United States:
DS 225K-Channel 25 uses one direct-sequenced channel at
225,000 bits per second. This one moderate-speed channel uses
all available bandwidth.
DS 090K-Channels 10 through 40 use one of several direct-
sequenced channels at 90,000 bits per second. Seven low-speed
channels share the available bandwidth.
DS 450K-Channel 25 uses one direct-sequence channel at
450,000 bits per second. This one high-speed channel uses all
available bandwidth.
Multicast Filter Determines if this radio can receive and send multicast frames.
File Name Specifies the name of the radio's driver software. Intermec
recommends that you change this name only when directed to
do so by Intermec Technical Support.
Hello Period Controls how frequently the access point broadcasts hello
messages on this radio port. Hello messages help maintain the
spanning tree and serve as beacon messages to synchronize
communications with end devices.
