I'm thinking of buying a GPRS shield for an Arduino. Since Adafruit doesn't have any, I have been looking at this one.
However, I'm having trouble picking out these specs:
GPRS multi-slot class 10/8
GPRS mobile station class B
Compliant to GSM phase 2/2+
Class 4 (2 W @850/ 900 MHz)
Class 1 (1 W @ 1800/1900MHz)
Control via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands)
Can you explain their significance to why they are important when it comes to picking a GPRS equipment? Thanks in advance.
