A kind of secondary wireless network platform
Technical field
The utility model relates to field of wireless transmission, particularly relates to a kind of wireless network platform.
Background technology
Internet of Things is briefly the interconnected of thing and thing, realizes real-time status perception and the real-time intelligent of things are controlled.Obviously wiring does not gear to actual circumstances everywhere, will be that cable network well replenishes and extends and adopt wireless technology as the transmission means of its front end perception data.
Radio Transmission Technology is very abundant at present, comprising: bluetooth, Zigbee, 433M ultrashort wave data radio station, GPRS etc.Owing to having the characteristics such as cheap, low in energy consumption as wireless technologys such as 433M, GPRS, can be by large-scale application in some industries, but due to its technology exists respectively that bandwidth is low, transmission range is near, should not networking, can't incorporate the problem such as IP network, so there is certain application bottleneck in Internet of Things!
