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

述: Product Overview :

高性能无线射频单元 LA-850V3 is a wireless data communication terminal with fast switching characteristics and built-in high - performance wireless RF unit . Widely used in cruise ship, rail transit, railway, driving school subject two, subject three and other application scenarios that require vehicle communication terminals to quickly switch between multiple wireless base stations. It has a variety of fast switching mechanisms such as roaming signal strength thresholds and background scanning modes. Provides high-bandwidth, low-latency data roaming services in high-speed mobile environments.

点: Main features :

l         AR 9344 CPU ATHEROS AR 9344 CPU

l         MB Flash, 64 MB SDRAM Memory: 16 MB Flash, 64 MB SDRAM

l         2个10 / 100 / 太网端口 Supports two 10/100 / Ethernet ports .
