The concentrator module DRF7020M13C is designed specially for AMR applications. The network (MNET) adopts reliable MESH structure and the routing level is up to 10. The Max. number of nodes in a network can reach 1024. Each module use 6 bytes ID as address. The function of each node module is the same and has the routing function so any independent router is not necessary. The network nodes are PnP so the installment of network is very simple and no manual setting is needed on the spot.

The network constructed with DRF7020M13C and DRF7020M13N can optimize routing by itself. It can automatically find and delete net nodes. It also can recognize any ineffective node and restore the routing link actively in order to make the network work in the best status. DRF7020M13C module is designed based on ADF7020 RFIC. The data link coding uses Innovative coding technology EDAC (looped interleaving Error Detection and correction) with coding gain up to 3dBm which anti-interference and sensitivity are improved significantly. The communication distance between nodes is about 600~800meters, which makes the radiating distance of MNET network up to 4km.
