Wireless development module

Introduction:

WMRNET wireless meter reading network is a wireless AD hoc network specially developed for three table reading. The system adopts a reliable network topology structure. The maximum level of the network is 10, and the maximum number of nodes can be 1024. WMRNET network is a peer-to-peer network. Each module is the same and has routing function. There is no separate rout Features:

"Fully AD hoc network, automatic routing optimization, automatic discovery and deletion of nodes

"Robust MESH structure, stable performance, high reliability

"10 level routing, maximum support up to 1024 nodes

"Plug and play, the networking process is completed automatically, without manual parameter setting on site

"The network is fast, the meter reading speed is fast, and the success rate of a meter reading is high

"Free wireless metering frequency (470-510mhz), multiple frequency points can be set

"The node module adopts ADI high-performance RF chip

"The coding uses efficient cyclic interleaved error correction coding

"Strong penetration, long range, outdoor network coverage radius of more than 4Km

"Uses a uniform 6-byte ID and supports various protocols

"Excellent value for money er.

WMRNET network can automatically optimize the network route, automatically discover and delete nodes, for the failure of nodes, WMRNET has the function of automatic identification, and can automatically repair the route, so that the network is in the best state of communication, because of the mesh topology, network reliability and meter reading success rate have a high performance.

WMRNET wireless network module is embedded in the high performance RF chip of ADI Company in the United States. The software data link coding innovatively adopts the efficient cyclic interweave error correction coding, which can correct up to 24bits of continuous burst error. Its coding gain is up to nearly 3dBm, and the anti-burst interference and sensitivity are greatly improved. The communication distance between modules is more than 500-1000m. WMRNET wireless network has strong penetration ability and long distance, and the coverage radius of outdoor network is more than 4Km.
