neighborhood area network (smart grid) (NAN)
The term Neighborhood Area Network (NAN) is used for the shared use of broadband connections, but also as a network concept for smart grids. From a broadband perspective, a Neighborhood Area Network is an extension of existing broadband connections. This can be a DSL connection, a cable modem or a WLANaccess point. Neighborhood Area Networks use the connections or access points of wireless LANs.
In order to cover as large an area as possible in terms of radio radiation, the radiation should be omnidirectional. Users connecting to the access point can do so using a directional antenna, which has a higher antenna gain and thus makes better use of the low field strength. In this constellation, ranges of up to one kilometer can be bridged.
Several users can connect to a Neighborhood Area Network and then have direct access to the Internet. The fact that several participants share the connections means that the costs for the individual are relatively low. However, the data transfer rateis also reduced if many users have to share the available bandwidth.
In smart grids and microgrids, NAN networks consist of multiple home area networks(HANs) and cover smaller local areas. They connect many smart meters, or smart meters, to a common data collection point. In smart cities, Neighborhood Area Networks can interconnect street lights, among other things. Neighborhood Area Networks transmit their data using standard and proprietary protocols. For example, with the IEEE protocol802.15.4. For smart grid applications, the ZigBee Alliance, since 2021 the Connectivity Standards Alliance( CSA), had standardized a Neighborhood Area Network (NAN) under the brand name JupiterMesh in June 2016.
