I am a little confused about the A-GPS. I have read the articles about its working and benefits over GPS but I have following questions (Here i am concerned with 5800 Xpress Music A-GPS);
- Could A-GPS be used as standalone GPS receiver? I mean if you are out of network service range but you can get GPS satellite signals, would in such case A-GPS would work?.
- Could we use A-GPS with WLAN? or it always requires GPRS/EDGE access point?
- Would it work with any service provider(which has GPRS/EDGE)? or it requires additional support from service providers?
The thing which confused me is that when I compared the specification of N95 with 5800 Xpress Music, I found that both have A-GPS but only N95 has GPS. This confused me that A-GPS couldn't be used as standalone GPS (When you don't want to use network trafic). Please someone guide.
