LA-850 series wireless transmission equipment has the function of fast communication with various fixed base stations during fast movement to realize high-bandwidth data backhaul communication, and built-in high-performance wireless RF unit. Widely used in cruise ship, tunnel inspection, inspection, robot communication, rail transit, railway, driving school subject two, subject three, unmanned driving, etc. Real-time online communication between the mobile terminal and the back end of the center is required during the movement process, and In the application scenario of fast switching of multiple wireless base stations, it has multiple fast switching mechanisms such as roaming signal strength thresholds and background scanning modes, which can provide high-bandwidth, low-latency data roaming services in high-speed mobile environments.
LA-850 is divided into two parts. LA-850V1 is a handheld or portable mobile terminal wireless communication device. It supports hand-held or fixed on small mobile devices. The terminal device can be used with different specifications of orientation or according to the needs of wireless monitoring. Omnidirectional antenna. LA-850V2 is a fixed access base station, which is installed on the line during the movement of terminal equipment to communicate with the terminal. It can be used with different specifications of directional or omnidirectional antennas according to different needs.
