EnGenius 08112021 DuraFon Roam RSSI Tool
Built into each DuraFon ROAM handset is a great tool to identify the best area(s) for the base unit(s) to be installed to provide the best coverage for the handsets.
Procedure for DuraFon ROAM RSSI Testing
- The DuraFon ROAM requires a BSC to register the base and handset to conduct the RSSI testing.
- Once the handset and the base are registered to each other, the RSSI testing can be done between these units.
- The base unit will be required to be powered at each location to be tested and the handset to be charged
- Any DuraFon ROAM handset can be used, it does not have to be an administrator handset to conduct the RSSI testing
- An outline or floorplan of the area should be available to note test results
- There are two different sets of number to be noted during the testing: BER & RSSI
- The RSSI test is located in a hidden menu and follow the below instructions to conduct the test:
On the handset, press MENU, # # # # *, and then “SELECT” for HS to BS item in BER test.
The display will show something like
- The received bit error number; BER (left) and frame error number; FER (right) at base side.
- The received the bit error number; BER (left) and frame error number; FER (right) at handset side.
- ID of the other side (base)
- Own ID (handset)
For acceptable voice quality over air, BER in the row A and B should be under 142.
Then press “Down” key to see RSSI value and frequency offset.
- Frequency offset
- RXIF and RSSI of the other side
- Own RXIF and RSSI
- For acceptable voice quality over air, the RSSI value should be more than -80dBm.
- The frequency offset (FREQ) should be under ±1500Hz
- Note the BER & RSSI with the location of the base and handset on the floorplan.
- Move the base to another location with less obstacles or closer to weaker areas, then conduct the test again. Note these results.
- Repeat this test as necessary to identify the best area for optimal handset coverage.
- As in the example below, mark the readings for each area with the base unit location to identify the best base location. (Ex: b1 is base 1; 1-51 is base 1 with RSSI of -51).
