The LTE-M protocol is a technology designed specifically for the Internet of Things (IoT). It has become one of the most suitable LPWAN solutions for deploying IoT systems that require low consumption while covering large geographical areas. The LTE-M network offers long battery life (> 5 years), low and adaptable latency, extended coverage, and high and adaptable throughput.
The LTE-M protocol supports voice over IP, also known as Voice over LTE (VoLTE), which makes it the most suitable solution for IoT applications that may require some human interaction (smart home, alarm system or health monitoring systems).
The LTE-M protocol uses IP protocols such as IPv4, IPv6, UDP, CoAP, MQTT, etc. for connected objects. The unique competitive advantages of LTE-M include bi-directional communication in real time (upload and download speeds), a latency of a few hundred milliseconds, and extended coverage. In short, the LTE-M protocol is an ideal solution for IoT applications requiring low power consumption, extended coverage, and real-time communication.
The LTE-M protocol for connected objects is available in 60 commercial networks around the world. The main countries where the protocol is available are the United States, Japan, Japan, Canada, Canada, France, Canada, France, Canada, France, and the United Kingdom.
You can ask your local operator for an LTE-M service or use our multi-operator solution that guarantees coverage in several countries at attractive rates.
The MQTT (Message Queuing Telemetry Transport) protocol is used to send messages between devices connected with LTE-M, such as sensors, cameras, thermostats, etc. It is designed to be simple, effective, and easily implemented on devices with low power consumption and low bandwidth.
The MQTT protocol is often used with LTE-M to connect connected objects because it is designed to work effectively on networks with low bandwidth and low power consumption. IoT devices connected via LTE-M can send messages to an MQTT server, which can then forward these messages to an application. It is also used to send commands to IoT devices connected via LTE-M.
In order to secure communications, the secure version of MQTT, called MQTTS, is used primarily. MQTTS uses SSL/TLS to authenticate data transmitted from IoT devices, ensuring that data is protected from malicious interceptions and attacks.
The TLS ALPN extension is used to select which version of MQTT to use, the SNI extension to ensure the name of the MQTT server that should be used.
Finally, a unique signed certificate is used by each object, which gives them the right to publish and subscribe to certain MQTT topics.
