WLAN functionality test using SB-7 and Phoenix

Steps
1. Place the phone on the SB-7 WLAN test box (see figure below). The co-ordinates are E1 - for the upper left
foot.
Phoenix service software and turn the phone to normal mode.
2. Start
3. Make connection to the phone with
Normal or RF inactive mode via the
4. Search for SB-7 WLAN Test box via WLAN application. Go to Menu→settings→Connectivity→Wi-Fi.
Select the first item on the sub-menu Available Networks
5. If the name of the WLAN test Box"default" appears on the list of found networks, the phone is OK.
Note: Local WLAN environment may affect test results, especially if there are many WLAN access
points nearby and any of them are using the same WLAN channel as SB-7. If the phone is able to see
and connect to local WLAN networks via its own inbuilt WLAN menu, then the phone is OK even if
the SB-7 can not be detected. Consider repeating the test where local networks do not interfere with
the lower strength signal of the SB-7 box.
If you still can't find the name of the WLAN test Box (Default) on the list under Scan results, the
phone is not OK and you should proceed to WLAN troubleshooting.

WLAN layout and test points

The WLAN module has been optimised to achieve the smallest possible PWB area and adding test points will
compromise this layout efficiency. There is also an added risk that test point will compromise the WLAN
performance – the layout is quite sensitive and there have been EMC issues that were directly attributed to
use of test points.
Issue 3
Phoenix , if the phone powers up in local or test mode, then select
