Idle Mode
Interval
Set the idle duration in minutes. This is how long the MAX208M2W
Series waits during periods of no activity before going into idle mode.
CINR & RSSI
Refresh
Interval
Set the refresh interval in milliseconds for calculating the signal-to-
noise measurement (CINR) and signal strength measurement (RSSI) of
the MAX208M2W Series.
LDRP (Low
Data Rate
Protection)
Enter the Low Data Rate Protection (LDRP) time in milliseconds. If the
uplink/downlink data rate is smaller than the LDRP time, the
MAX208M2W Series sends a disconnect request to the base station.
LDRP TX
Rate
Enter the outgoing data rates for LDRP in bytes per second.
LDRP RX
Rate
Enter the incoming data rates for LDRP in bytes per second.
Connection Type Settings
Mode Select Select how the MAX208M2W Series connects to the base station.
• Auto Connect Mode - The device connects automatically to the
first base station in range.
• Network Search Mode - The device scans for available base
stations then connects to the best one it can.
BSID This displays the MAC address of a base station within range of the
MAX208M2W Series.
Preamble ID The preamble ID is the index identifier in the header of the base
station ’ s broadcast messages. In the beginning of a mobile stations ’ s
network entry process, it searches for the preamble and uses it to
additional channel information.
The preamble ID is used to synchronize the upstream and downstream
transmission timing with the base station.
Frequency
(MHz)
This field displays the radio frequency of the MAX208M2W Series ’ s
connection to the base station.
Bandwidth
(MHz)
This field displays the bandwidth of the base station in megahertz
(MHz).
RSSI (dBm) This field displays the Received Signal Strength Indication (RSSI),
which is an overal measurement of radio signal strength. A higher RSSI
level indicates a stronger signal.
CINR (dB)
R3/R1
This field displays the average Carrier to Interference plus Noise Ratio
for the current connection. This value is an indication of overal radio
signal quality, where a higher value means a better quality signal.
