SIM908 module is a complete Quad-Band GSM/GPRS module which combines GPS technology for satellite |
|
navigation. The compact design which integrated GPRS and GPS in a SMT package will significantly save |
|
both time and costs for customers to develop GPS enabled applications. |
|
Featuring an industry-standard interface and GPS function, it allows variable assets to be tracked seamlessly |
|
at any location and anytime with signal coverage. |
