MQTT Integrates MLiS Terminal with IIoT Connectivity



[Taipei, Taiwan, Jan. 18th, 2019] - MQTT (Message Queuing Telemetry Transport) system is one of the connection protocols in IoT projects to communicate with server. In addition, it uses subscribe operations to exchange data between clients and server. Furthermore, MQTT features small size, minimized data packets, low power consumption, real time and ease of implementation to make an ideal protocol and meet the needs of M2M (Machine to Machine) and IoT (Internet of Things).


MQTT is based on protocol and operated by publisher and subscriber patterns. "Broker" is the main task of MQTT to deliver messages to clients (subscribers). In other words, "broker" uses topic to receive messages from publishers (edge devices such as sensors; the received messages fall into different categories and then sending the classified messages to the clients (devices). That is to say, the topic is managed by MQTT broker. 





Realizing the potential market of the IoT (Internet of Things) and M2M (Machine to Machine) wireless solutions, MLiS promotes terminal series MLB-G4201 and MLB-G4202 to adapte the MQTT protocol. As for MQTT protocol, it integrates with MLB-G420x series to provide secure connectivity (Transport Layer Security) to monitor the environment and control the status through the real time event alarm. With regarding to MQTT Broker, MLB-G420x series supports the system to connect the data base and analyze the information through data collection in a wide range of applications such as IP surveillance, vending machine, or telemetry, etc. In addition, MLB-G4201 and MLB-G4202 provide a higher cellular bandwidth and more reliable connection to extend the transmission distance and centrally manage the devices which widely distributed in different areas.



Key Features (MLB-G4201 & MLB-G4202)

  • Dual band 2G/3G (EU/US) (optional for MLB- G4201)
  • Supports 3G and 4G global networks, including LTE advanced (optional for MLB- G4202)
  • -40 ~ 75 ℃ wide temperature in harsh environments
  • Dual SIM card for redundancy
  • 2 Ethernet ports for 10/100M connection
  • MCCP/MCCU support
  • 15 KV ESD protection
  • NAT/Port forwarding
  • Even trigger by GPRS/IO/Reboot/Relay
