MD-149 Overview

MD-149 is a 4G built-in DTU produced by eTung in 2016, and supports LTE-TDD and LTE-FDD 4G networks. Compared with MD-139 3G built-in DTU, MD-149 uses 4G high-speed communication module, and has higher speed of data transfer. MD-149 supports LTE-FDD/LTE-TDD/HSPA+/TD-SCDMA/GSM networks that include China Mobile’s 4G (TD-LTE) network, China Unicom and China Telecom’s 4G (LTE-FDD) network; it also supports China Mobile & China Unicom’s 2G/3G networks, in case 4G network signal is weak, it can use 2G/3G networks. In LTE 4G network, in theory the downlink speed can reach 100Mbps, and uplink speed can reach 50Mbps, which is approximately 10 times of speed in China Unicom’s WCDMA 3G network (the downlink speed 14.4Mbps, and uplink speed 5.76Mbps). So MD-149 4G DTU is much suitable in occasions that have large quantity of data transfer or have high real-time property.

 

MD-149 has original built-in design and has smaller size; it has more flexible interface, its double-line hole interface can connect extended power supply, LED indication lights, SIM card pedestal and user serial port, etc. MD-149 makes built-in wireless applications easier for industry customers. Separate wireless application with wireless communication device and user device installed separately, has not only bigger space usage, and the outlook has no integrity, but also the installation, training, and debugging are more complicated. eTung’s MD-149 has smaller size and flexible interfaces, and can be quickly embedded into user device, thus integrates the user device and wireless device into one product. The launch of MD-149 will definitely lead the integration trend of wireless applications.

 

MD-149 can be quickly embedded into user device that need 4G wireless communication, such as appliances, meters, data terminals, RTU, or IPC. It transfers data via 4G network from the user device that connects with it to a host on the internet, and implement remote and transparent data transfer. It can be used widely in various industries related to “Internet of things”.
