Re: My non gps phone
said by wifi4milez  :said by Austinloop :It is more than 3 years old and works just fine, no GPS. Within 1/2 mile is a lot of space in my current city. What specific phone is it? Some phones have had GPS chips in them (Nextel for example) since 2002. GSM phones don't even need GPS at all. They use TDOA triangulation for 911. My AT&T LG CU515 which i got this year has no GPS chip. My Sprint and Nextel phone however does. But AT&T and T-Mobile don't use GPS to determine 911 location |

Some GSM handsets use TDOA, while others use GPS. Still others use AoA technology to determine your location. It all depends on the manufacturer and how they designed the phone.

| A phone will only use what the carrier supports. If AT&T hasn't implemented an A-GPS server to connect to E911 it's not going to utilize the GPS chip in the phone. AFAIK AT&T and T-Mobile have only deployed TDOA based E911 technologies right now. Sprint/Nextel, Verizon and the rest of the CDMA carriers use Qualcom based A-GPS/AOA for E911. |

Again, I need to disagree. The iphone has A-GPS, as do a few other ATT phones. In fact, ATT just had a press release that they use A-GPS in their phones the other day. It looks like they officially started offering it last month, but now most of their phones will likely have it.
