This is a name that is assigned to a SIM Card from the cell phone carrier (ex: AT&T). It tells the carrier what IP address should be assigned to your device (Syrus) in order for it to connect to the internet, or a private network.

The APN is configured with the RF command.

AGPS

January 22, 2014/in gps /by leo

AGPS – Assisted GPS – is a method of accelerating the time it takes the GPS Receiver to “fix” it’s latitude and longitude. The way it works is by taking assistance from GPRS and at times, the service provider network information, to pin-point the current location faster and accurately. This improves GPS availability even in cities with high buildings where the GPS conditions are bad.

January 20, 2014/in general /by leo

Global Positioning System – space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.
