Description: LC970B是一款专门针对网络摄像机设计的大功率WiFi模块。针对普通功率WiFi模块在视频传输等高
数据量，较远距离等应用场合性能受限制的问题，LC970B采用高集成度单芯片RT3070方案，配合输出
功率达27DBm/500mw的高性能外置PA（射频功率放大器），可以显著提升WiFi传输效能。
LC970B 软件驱动层面支持良好，可以在Windows/Linux/Android等多系统下稳定运行，不仅支持
station模式，而且可以工作在softap模式。此外，LC970B也可以良好支持smartconfig，smartlink，zerolink
等一键配置功能，可以广泛应用在家用网络摄像机产品中。
LC970B模块采用邮票口接口，方便客户直接表贴在产品电路板上，降低电路空间。-LC970B is a high power WiFi module specifically designed for network camera. As we all known the WiFi module with ordinary power is restricted in applications such as video transmission which need to transmit mass of data in long distance. LC970A uses high integrated single chip RT3070, high-performance external PA with 27 dbm/500mw output power(RF power amplifier) and the low-noise amplifier, can significantly improve WiFi transmission efficiency.
LC970A has a good software driver and can operate stably under Windows/Linux/Android system. It supports not only STA mode but also AP mode and it also supports one key configuration function such as smartconfig, smartlink, and zerolink, can be widely used in home network camera.
LC970B module uses stamps interface for clients to attached it to circuit board directly and save the space of the circuit. Platform: |
