The following table explains each 902 MHz radio parameter.
Parameter Explanation
Port Control Enables or disables 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. The following combinations are valid in the United States:
•

Mode-Channel combinations:
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-Channel 10 through 40 Uses 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 packets.
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 packets on
the 902 MHz port. Hello packets help maintain the spanning tree and
serve as beacon messages to synchronize communications with power-
managed end devices.
