A hardware SMS gateway is a telecommunications device that sends and receives short message service (SMS) and multimedia message service (MMS) messages through a mobile network using one or more SIM cards and cellular modems.[1] Hardware SMS gateways operate within an organisation’s local network, while online SMS gateways transmit messages through remote, web-based services.[2]
History
editEarly SMS gateways were physical devices connected directly to local systems for sending messages through mobile networks.[1] These devices preceded cloud-based SMS services and continue to be used in environments where a direct connection to a mobile operator is required.[3]
Operation
editA hardware SMS gateway includes a cellular modem, a SIM interface, and a network connection such as Ethernet or Wi-Fi. Messages are submitted to the device through an API, HTTP request, or email protocol and are transmitted through the mobile network.[4] Hardware SMS gateways and GSM modem units are described in academic literature as components for remote monitoring and control systems.[5]
Applications
editHardware SMS gateways are used in network and system monitoring software to send text notifications. Zabbix supports SMS delivery using a connected GSM modem,[3] and Paessler PRTG provides configuration for external hardware gateways.[6]
Academic studies report uses of GSM–SMS gateways in industrial automation,[7] and for real-time transmission of field data in telemetry systems.[8]
Comparison with online SMS gateways
editHardware SMS gateways use local SIM cards and transmit messages directly through a mobile network. Online SMS gateways rely on an internet connection to communicate with a provider’s platform.[2]
