LA-850V2 fast switching wireless transmission base station

Main Products: wireless monitoring, wireless monitoring equipment, wireless video transmission, wireless monitoring system, wireless video monitoring

Product Overview:

LA-850 series fast-switching wireless data transmission is a wireless data communication terminal with fast switching characteristics and built-in high-performance wireless RF unit. It is widely used in cruise ships, tunnels, rail transit, railways, driving school subjects 2, subjects 3, unmanned driving, etc. It is necessary to achieve real-time online communication between the mobile terminal and the back end of the center during the movement process, and to quickly switch between multiple wireless base stations Application scenarios, it has multiple fast switching mechanisms such as the roaming signal strength threshold and background scanning mode, which can provide high-bandwidth, low-latency data roaming services in high-speed mobile environments.

The LA-850 is divided into two parts. The LA-850V1 is a handheld or portable mobile terminal, which can be carried around or fixedly installed inside a small device, and directional or omnidirectional antennas with different gains can be configured according to actual needs. LA-850V2 is a wireless access base station, which is reasonably arranged on the line of the terminal mobile line process to communicate with the mobile terminal. Fixed base stations also use directional or omnidirectional antennas with different gains in accordance with the needs of different scenarios.


Second, the main features:

  • ATHEROS AR 9344 CPU

  • 64 MB Memory: 64 MB  

  • Flash: 16MB

  • 1个10 / 100 / 太网端口 RJ 45 Supports one 10/100 / Ethernet port , RJ 45
