What You Don't Know About Industrial GSM/GPRS Modem Communications

Executive Summary

Cellular communications are becoming increasingly popular in industrial process applications where traditional wired and wireless communications are not possible. The cellular network provides access to devices anywhere a cellular connection exists. However, when using cellular communications, a number of things must be considered to ensure solid network communications. In the United States, carriers like AT&T typically do not allow the use of "Voice" networks like GSM (Global System for Mobile Communications) for M2M data communication applications. This is because modems could monopolize network bandwidth, thus reducing network access for the carrier's typical customers. However, it is also advantageous for the user of cellular modems to avoid using the GSM network because of billing methods.
