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

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).
