Re: [WISPA] T-Mobile [EMAIL PROTECTED]
They wouldn't sell me a phone until I gave them a service address. As I understand it, if they can't determine a location from the regular cell tower triangulation, they use that address. Personally, I don't care all that much. I lived for thirty years before the 911 system was available. I understand a few people have perhaps died from e911 not working over voip, but autos kill 30,000+/ year and we still use them. Technically, I don't see how you can track IP address location very easily. I don't look forward to a government mandated system that I need to feed info into. We still have a landline at our house, but never use it. I would cut that $35/month if things got tight.

Re: [WISPA] T-Mobile [EMAIL PROTECTED]
GPS co-ordinates, your personal address, triangulation of cell towers to pin point your locaton. None of that satisfies e911, like the e911 that we are required to do provide to become a voip carrier and provide voip service. I say, if they can do this, there is a double standard and we're getting the short end of the stick. Why can't I sell wifi voip service with out the e911 again?

Re: [WISPA] T-Mobile [EMAIL PROTECTED]
I did a few tests at the East Lansing Starbucks. I start the call on WiFi and walk out the front door. By the time I'm 20' away it has switched over to a tower. I didn't detect any noise during the switch, but I was outside next to a 3 lane road. Unfortunately that doesn't work at my house. If I move out of Wifi range (currently about 20' from my porch for this phone), it drops the call. I need to move about 7 miles before I can reliably hit a T- Mobile tower. The Starbucks has a T-Mobile Hotspot, the phone usually automatically switches over to WiFi there. (I think that is how it is supposed to work) Still a few bugs in the system: sometimes I have to use the phone menu to search for WiFi at Starbucks, then pick the Hotspot. It automatically connects, don't have to enter a security code or anything. And rarely I have to power cycle the phone before it will connect via WiFi. On Jul 20, 2007, at 8:54 PM, Felix A.

No, but voip does. When it's not talking to a cell tower and is talking to a wifi ap, it's voip.

Re: [WISPA] T-Mobile [EMAIL PROTECTED]
Means they can either use the cell towers to triangulate the position of the handset, which works better as more towers become visible. Or they have an actual GPS receiver in the handset that may or may not be usable by the handset owner with or without a 'GPS feature' enabling subscription. The telco policy of nickel-and-dimeing for every little feature is very irritating, including how they handle data and SMS. -hk On Jul 21 2007, George Rogato wrote: What does that mean.

[WISPA] T-Mobile [EMAIL PROTECTED]
T-Mobile launched their [EMAIL PROTECTED] service at the end of June. I picked up one of these cell phones a few weeks ago. The deal is for an extra $10/month, you get unlimited calls in the US if they are made over wifi. The wifi connection generally works with any open AP, or if you know the security key you can enter that. It also automatically connects to T-Mobile Hotspots, such as might be found at Starbucks. Once you start a call on wifi, you can move out of wifi range into tower range it seamlessly switches over. The call is billed according to where it starts. I had actually sampled a T-Mobile phone, then returned it the day this [EMAIL PROTECTED] service launched. Most of the places I hoped to use it, I had no signal. But I like this new combo phone quite a bit. For example: my WISP office is in my basement. I've used Verizon cell phones for years, based on having them work almost everywhere I go. But no service in my basement. The T-Mobile phone happily uses my net connection and sounds better than any cell phone I have used. Ditto for a few locations at work, such as a server room. No cell service, but wifi is fine. One thing I don't like is that the phone doesn't include a web browser. If you are at a location that requires agreeing to TOS before using the wifi, you can't do that just using the phone. I've used some other VOIP systems before (Packet 8, Skype, almost went with SunRocket - that was close) but haven't really liked them. -- An idea for WISPA leadership: think about brokering a deal with T- Mobile to expand their hotspots to members POPs. They only have about 7500 hotspots in the US. For example, there are none in Michigan's Upper Peninsula, and the only one in the north half of the Lower Peninsula is Traverse City. Some technical details: The T-Mobile phone uses technology called UMA to encapsulate GSM over IP. The packets are UDP encapsulated IpSec. The call I monitored averaged 60 packets/sec. All traffic was to/from one IP address using port 4500. Bandwidth used was 9516 bytes/second average.

No cell service, but wifi is fine. One thing I don't like is that the phone doesn't include a web browser. If you are at a location that requires agreeing to TOS before using the wifi, you can't do that just using the phone. I've used some other VOIP systems before (Packet 8, Skype, almost went with SunRocket - that was close) but haven't really liked them. -- An idea for WISPA leadership: think about brokering a deal with T- Mobile to expand their hotspots to members POPs. They only have about 7500 hotspots in the US. For example, there are none in Michigan's Upper Peninsula, and the only one in the north half of the Lower Peninsula is Traverse City. Some technical details: The T-Mobile phone uses technology called UMA to encapsulate GSM over IP. The packets are UDP encapsulated IpSec. The call I monitored averaged 60 packets/sec. All traffic was to/from one IP address using port 4500. Bandwidth used was 9516 bytes/second average. Most packets were 158 bytes (the longest seen), a few were 142, and occasionally 60 bytes. -John Would you like to see your advertisement here?
