Configuration for DD-WRT access points to help the WIFI phones to save Battery and to Prioritize phone data so that other Wireless data will not drop calls.

Contents

Carriers

The only carriers that support UMA are T-Mobile wireless and Cincinnati Bell Wireless

Phones

This is most current list of phones that work with UMA:
Nokia 6086
Samsung T-409
Blackberry Pearl 8120
Blackberry Curve 8320
Blackberry 8820
Samsung t409
Samsung t339
Nokia 6301
Samsung Katalyst

DD-WRT Configuration

Enable wireless multimedia support: (This should prioritize your cell phone calls and help your phone to use less power)

  1. Enable WMM support in the advanced wireless tab (the default WMM settings should be fine)
  2. Log on to the router via telnet/ssh type 'wl -i $(nvram get wl0_ifname) wme' (the command should return 1 if everything is successful)

Dropped calls

Users have noted that using the following settings have solved dropped call issues:

  • Fragment Threshold : 2304 (256-2346)
  • RTS Threshold : 2304 (0-2347)
  • Beacon Interval : 50 (20-1024 ms)

This was from the following thread at Howard forums: [1]
User Justin Poggioli wrote in to tell me that the Beacon Interval fixed his dropped call problems with the fragmentation and RTS threshold settings changing very little. He also notes that using any more then 50mW of output power seemed to be giving him clarity of voice issues.

TODO

  1. add settings for traffic shaping so that wired connections do not cause dropped calls
  2. get other users opinions on what Traffic shaping should be used.

Notes

  1. Information on wmm and dd-wrt found here
