SIM508 GSM/GPRS+GPS Module
SIM508 module is a Tri-Band/Quad-Band* GSM/GPRS-enabled module that
is also equipped with GPS technology for satellite navigation. The
compact design of the SIM508 makes it easy to integrate GSM/GPRS
& GPS as an all-in-one solution.You will save significantly
both time and cost for the integration of additional hardware
components.
The combination of both technologies can fit almost all the space
requirement in your application, such as PDA phone, GPS hand-held
device and other mobile device, it allows vehicles and people to be
tracked seamlessly at any location and anytime.
