私は彼に彼のT移動式8320の問題および彼の顎骨のbluetoothのヘッドホーンがいかにあっていたか詳しく述べているポールから電子メールを先週得た。 Bluetoothで彼が呼出しを落とす間、彼がUMA上の呼出しをしたときにそれはなる。 これは彼の古い顎骨によってちょうど解放された新しい顎骨によってだけ起こらなかったが。
ポールはそれからUMA、WiFi、及びBluetoothがすべて互いに干渉するかもしれない2.4 GHzバンドで動くことを学んだ。 UMAおよびBluetoothのあるヘッドホーンのための回避策がないこと彼に言われるT移動式。
私は知っている 何人かの人々 切り刻まれた(ddwrt) Linksysを使用して無線ネットワークのファームウェアは新しい特徴をこの問題を修理するBluetoothの共存モードと呼ばれて得た。
誰でもは回避策を見つけたか。 またこの問題を経験しているか。 感じなさいコメントのポールを助けること自由に…

I also have the T-Mo 8320. As I understand it the WiFi UMA conflicts with other devices running on 2.4 GHz. The cordless phones T-Mo actually sells for use with Talk Forever Home Service run on 6.0 GHz because T-Mo has documented some interference for 5.8 GHz phone as well. I personally use two 5.8 GHz cordless phones with my Talk Forever Home Service, and have not had any problems on call quality at all. I would therefore propose not to use 2.5 GHz wireless devices, but stick to 5.8, 6.0, or other. T-Mo/RIM should be able to provide support on this issue. I have personally found them always helpful.

Hi - I’m the guy that emailed. Some additional color commentary: The new Jawbone is Bluetooth 2.0, and the old one (which works fine) is Bluetooth 1.5. So it may be a difference in the standard, or the power of the signal, etc. Either way, I just thought it might be of interest to people who were considering the new Wifi Pearl. It’s a shame because the new Jawbone was awesome, very small and light, great charging connection - they really solved some of the issues with the older one. I work from home and probably spend 3-4 hours per day on my UMA connection, so having a functional headset is kind of non-negotiable…

I believe that you are a tad off on the “6ghz”. The technology at use in the TMobile Hotspot at home Unlimited plan is actually “DECT 6.0″ which is a revision of the DECT technology that Europe has used for many years. It actually operates at 1920-1930mhz, 1.9ghz.
The reason that 5.8ghz has interference, is simply because such a small wavelength has signal loss going through a sheet of paper, let alone metal, wood and brick. The lower the frequency, the easier it passes through objects.
More info can be found on Wikipedia; http://en.wikipedia.org/wiki/DECT

Mike: I didn’t buy one of the T-Mo cordless phones, I just remember they rep in the store saying it was 6.0 GHz and was guaranteed to work with the new linksys router while 2.4 and 5.8 GHz they would not “guarantee.” If that was incorrect then that’s just what I was told by the rep.

I’ve been able to use my curve and my 8120 with my H680 and H12 on wifi

I have the Tmo Curve and for my house phone i have Vonage.. and UMA will NOT WORK if Vonage is plugged in.. but once u unplug the Vonage Modem.. vulah!!! it works like a charm.. HOW Come?

Carlos: MMmmm, that’s a pickle. I used ViaTalk (Linksys router) and my WiFi T-Mo UMA Router (also Linksys) together at the same time for about 6 months had never had a problem. Now I have the T-Mo Talk Forever Home Service ($10/month unlimited) and still don’t have a problem.
Do you have your routers fighting for the same IP? Could also depend on if you have your Vonage plugged into WiFi (maybe T-Mo) router, or WiFi Router plugged into Vonage. I used a non-T-Mo D-Link router for a few weeks, which worked by not perfectly. With a T-Mo Linksys wifi router worked much better. Best bet is to call T-Mo HotSpot support.

I am using the dd-wrt Linksys firmware with the Bluetooth Coexistent mode turned on but my bluetooth headset still does not function at all with the 8320 using uma.

I have a similar problem. I too work from home and spend a great deal of time on the phone via UMA. I have a T-Mob 8320, WRT54G V5, Moto H700 and the new Moto H710. The H700 works fine with the whole setup and I am able to carry on business as usual. Unfortunately the H700 has taken some abuse and needed to be replaced. I purchased the H710 (which by the way is phenomenal on edge) and cannot place a call with it on UMA. It eventually forces the phone into edge, which is worthless to me as the package I am on is limited.
I ran across the post that you referenced concerning the DD-WRT firmware and the Bluetooth Coexistent capability. I was going to give it a shot but I just don’t know enough about flashing a router to feel comfortable doing it. Does anyone know a step by step guide that I could reference to flash the modem with my particular router version?
Or, does anyone know a really good router that would already have this Bluetooth Coexistent mode on it that I could just purchase? I am getting kind of sick of messing with this thing.
