==SIM808 module==
S
IM808 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.
General features:
* Quad-band 850/900/1800/1900MHz
* GPRS multi-slot class 12/10
* GPRS mobile station class B
* Compliant to GSM phase 2/2+
– Class 4 (2 W @ 850/900MHz)
– Class 1 (1 W @ 1800/1900MHz)
* Bluetooth: compliant with 3.0+EDR
* Dimensions: 24*24*3mm
* Weight: TBD
* Control via AT commands (3GPP TS 27.007,27.005 and SIMCOM enhanced AT Commands)
