For the WIMAN STAR enter the commands „stat wl“
and „stat wl<nodeID>“ to ensure proper functioning of
the data exchange.
-
For the WIMAN LINE enter the command „stat sync“
to check the setting of both signals (both signals have
to be set to „On“).
5.2.1 Continue the Tests
•
Switch on the WIMAN radio modem next to the synchroni-
zation master.
•
Switch off the synchronization master.
•
Perform a reception test.
•
Check the X.21-interface (see chapter X.21-Test above).
•
Switch the synchronization master back on.
•
Perform another reception test to make sure the synchroni-
zation cable does not produce any errors (the radio statistics
should not differ substantially from the preceding ones).
5.2.2 Test the Remaining Modules
•
Switch on the next WIMAN.
•
Switch off all WIMAN radio modems that were tested be-
fore.
•
Perform a reception test.
•
Check the X.21-interface (see chapter X.21-Test above).
•
Switch on all WIMAN units that were tested before.
•
Connect the synchronization cable to the last tested
WIMAN radio modem.
•
Perform another reception test to make sure the synchroni-
zation cable does not produce any errors (the radio statistics
should not differ substantially from the preceding ones).
5.3 Transmission Speeds
5.3.1 FTP-Download from an FTP-Server
The maximum transmission speed of the WIMAN radio modem
at optimum conditions is about 25 … 30 Kbytes/s at 2FSK and
about 55 … 62 Kbytes/s at 4FSK (depending on the extend of
utilization of the network).
