9.4.11 Configuring the Browser Application
Follow the manufacturer's instructions for configuring the end-user’s browser, so that it
correctly uses the PC Ethernet interface. Once you have done this:
1. Launch the browser
2. Confirm access to sites of interest.
9.4.12 Completing the Installation
1. Configure the remaining PC applications, as required.
2. Re-activate the end-user’s cordless phones, and any other 900MHz ISM-band
equipment that was turned off at the beginning of the installation. Note the following
points:
• Cordless phones operating in the 900MHz ISM band can disrupt service to
the EUM if precautions are not taken.
• Run an FTP throughput test, and turn on the cordless phones in sequence,
while monitoring the downlink throughput. Since there is naturally a wide
variation in the downlink speed, for reasons more associated with the network
than with the performance of the LMS4000 wireless service, repeat the tests
several times to confirm whether or not the end user’s cordless phones are
going to affect the EUM performance.
• If the cordless phones do affect the performance of the EUM, move the
cordless phone base station to a location as far from the antenna as possible.
Instruct the end user to avoid using the cordless handset in the proximity of
the antenna, particularly when the EUM is being used.
9.4.13 Baselining the Installation
Once you have completed the installation, WaveRider recommends recording the following
information:
• EUM IP addresses
• EUM radio settings
• RSSI readings
• Tx retry rate readings (displayed with the RSSI readings)
• SQ, RNA, and RNB (displayed with the RSSI readings)
If you have problems with the EUM at a later date, you can compare the latest site settings
and RSSI readings with the original settings in the site installation record.
