• "Always-On" Connectivity: GPRS provides persistent connectivity without the need for manual dial-up, which is ideal for continuous monitoring applications.
• Packet Switching: Data is broken into packets and sent over shared radio channels, making data transfer more efficient and generally billed by volume of data rather than connection time.
• GSM Network Compatibility: These modules operate on existing GSM (Global System for Mobile communications) infrastructure, typically using 900 MHz and 1800 MHz frequency bands, allowing for wide coverage.
• TCP/IP Stack: Most industrial GPRS modules have an integrated TCP/IP protocol stack, enabling direct internet connections to a remote server or cloud platform.
• Data Rates: GPRS offers theoretical data speeds up to 171.2 kbps, although real-world speeds for IoT and M2M applications typically range from 15 to 40 kbps, which is sufficient for small, bursty data transfers.
