Specifications

GPS Module GPRS Module GSM Module Wireless Module (SIM548C) is a compact Quad-Band GSM/GPRS-enabled module that is also equipped with GPS technology for satellite navigation. The compact design of the SIM548C 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.

Featuring an industry-standard interface and GPS function, the combination of both technologies allows valuable asset to be tracked seamlessly at any location and anytime with signal coverage.
