Telit SGX31 Smart LTE-M, USB2.0 NB-IoT Gateway
The Telit SGX31 Smart LTE-M is a USB 2.0 NB-IoT gateway designed for cellular IoT connectivity. It supports LTE-M and NB-IoT with 2G fallback, providing connectivity options for applications that require cellular data communication.
The gateway supports LTE Cat. M1, LTE Cat. NB1, and LTE Cat. NB2, along with quad-band GSM at 850, 900, 1800, and 1900 MHz. It also supports SMS and GNSS with GPS, GLONASS, BeiDou, and Galileo.
The SGX31 provides multiple connectivity and control options, including USB2.0, RS-232, cellular and GNSS antenna connections, and a Mini-SIM card reader. It supports standardized Hayes, TS 27.007, TS 27.005, and Gemalto M2M AT commands.
For network services, the gateway supports TCP server/client, UDP client, DNS, Ping, HTTP client, FTP client, and MQTT client. It also provides secure connections using TLS/DTLS and includes an embedded IPv4 and IPv6 TCP/IP stack.
The gateway operates from a 5 - 30 V supply voltage range and is designed for an operating temperature of -30°C to +75°C. Measuring 191 x 143 x 44 mm excluding connectors and weighing approximately 130g, it is suitable for cellular IoT deployments requiring flexible interfaces and wide environmental operating conditions.
