GSM-GPRS-GPS SIM808 Module

SIM808 is a quad-band GSM/GPRS module that works on frequencies GSM 850MHz, EGSM 900MHz, DCS 1800MHz, and PCS 1900MHz. It features GPRS multi-slot class 12/class 10 and supports the GPRS coding schemes CS-1, CS-2, CS-3, and CS-4. The GPS solution offers best-in-class acquisition and tracking sensitivity, time-to-first-fix (TTFF), and accuracy.

Features:

• Quad-band 850/900/1800/1900MHz
• GPRS multi-slot class12 connectivity: max. 85.6kbps(down-load/up-load)
• GPRS mobile station class B
• Controlled by AT Command (3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands)
• Supports charging control for Li-Ion battery
• Supports Real Time Clock
• Supply voltage range 3.4V ~ 4.4V
• Integrated GPS/CNSS and supports A-GPS
• Supports 3.0V to 5.0V logic level
• Low power consumption, 1mA in sleep mode
• Supports GPS NMEA protocol
• Standard SIM Card

void setup()
{
mySerial.begin(9600);   
Serial.begin(9600);   
delay(100);
}
void loop()
{
 if (Serial.available()>0)
 mySerial.write(Serial.read());
 if (mySerial.available()>0)
 Serial.write(mySerial.read());
}
