Therefore it is possible to leave the controlling application always connected and ready to receive send data on demand while paying only for the data really exchanged The drawback of the GPRS connection is that the controlling application must have its own TCP IP protocol stack embedded to decode the packets that arrive from GPRS and encode the ones to be sent through the internet There are few considerations than must be done on the GPRS connections e the GPRS connection speed with a GPRS class 10 multislot device is asymmetrical 3 time slots in reception 43200 bps max and 2 time slot in sending 28800 bps max or 4 time slots in reception 57600 bps max and 1 time slot in sending 14400 bps max e The controlling application of the module must have a TCP IP PPP software stack to interface with the GPRS modems e The controlling application must relay on some ISP that may be the Network Operator of the SIM to gain access to the internet through the GPRS connection e Because of the point before the receiving application must have internet access either e Since the communication is based upon TCP IP packets then it is possible to talk contemporarily with more than one peer e When required the data security in internet shall be guaranteed by security protocols over the TCP IP that must be managed by the controlling application NOTE For more detailed information about GPRS connections and practical examples please refer to the Easy G
