GPRS usage in tracking.

Imagine what kinds of problems a truck owner or an owner of many cabs might face. The things which can come to your mind are :-

a) He needs to know where is vehicle is, at any point of time.
b) Which of his vehicle needs a reschedule , dynamically.

The point a) can be addressed using a combination of GPS and GPRS technologies. This is what SmartTalk is trying to do.

A moving truck gets the location information from a GPS module.And later, using GPRS we can send the information to a TRacking Server. A truck owner with a laptop can actually see which of his vehicles is present WHERE at any point of time. Just check out their features page here

Infact, if an operator GSM operator provides a network node called SMLC, a mere mobile phone can provide tracking data. We can avoid the GPS angle altogether.

I dont know which GSM operators use SMLC. I will update it whenever I get the information.

Here is what mpirical companion says about SMLC :-

SMLC - Serving Mobile Location Centre
The SMLC is either a separate network element or integrated functionality in the BSC (Base Station Controller) that contains the functionality required to support LCS (LoCation Services). The SMLC manages the overall co-ordination and scheduling of resources required for the location of a mobile. It also calculates the final location estimate and estimates the achieved accuracy. The SMLC may control a number of LMU (Location Measurement Unit) for the purpose of obtaining radio interface measurements to locate or help locate MS (Mobile Station) subscribers in the area that it serves.
