technical field

The invention relates to the technical field of power line transmission data collection, in particular to a wireless communication network deployment power line transmission data collection system using multi-hop relays.

Background technique

Relay stations with flexible deployment characteristics (relay for short) can increase system capacity and expand network coverage, which makes multi-hop relay networks more and more popular. Compared with the traditional wireless network, more factors need to be considered in the multi-hop relay network to take advantage of the relay, these factors include the number of hops of the relay, the number and location of the relay, resource allocation and so on.

802.16m, or WiMAX evolution technology, is a wireless standard developed by the Institute of Electrical and Electronics Engineers (IEEE), and is usually called WirelessMAN-Advanced. After 802.16e introduced WiMAX to the mobile communication field, 802.16m became the second-generation mobile WiMAX international standard, and its downlink rate can reach 300Mbps. In the 802.16m standard, single-user and multi-user MIMO technology, multi-base station MIMO technology, etc. are introduced. In addition, in order to compete with LTE-A, and considering the performance improvement brought by the relay technology in IEEE802.16j, the relevant requirements of the relay are added to the 802.16m document, and develop together with IEEE802.16m.
