A low-power wide-area network (LPWAN) or low-power wide-area (LPWA) network or low-power network (LPN) is a type of wireless telecommunication wide area network designed to allow long range communications at a low bit rate among things (connected objects), such as sensors operated on a battery.[1][2] The low power, low bit rate and intended use distinguish this type of network from a wireless WAN that is designed to connect users or businesses, and carry more data, using more power. The LPWAN data rate ranges from 0.3 kbit/s to 50 kbit/s per channel.[3]

A LPWAN may be used to create a private wireless sensor network, but may also be a service or infrastructure offered by a third party, allowing the owners of sensors to deploy them in the field without investing in gateway technology.

Platforms and technologiesEdit

There are a number of competing standards and vendors in the LPWAN space, the most prominent of which include[4]:

Chirp spread spectrum basedEdit

Ultra-narrow bandEdit

Ultra-narrow band (UNB), modulation technology used for LPWAN by various companies including:

  • Sigfox, UNB-based technology and French company.[6]
  • Telensa[7] A Cambridge based company using UNB-based technology to connect and control streetlights and other city infrastructure.
  • Nwave,[8] proprietary technology developed in cooperation with MIT. Its first release without error correcting codes also forms the basis of the Weightless-N open protocol.[9][10]
  • Weightless, a set of communication standards from the Weightless SIG.[11]
  • NB-Fi Protocol, developed by WAVIoT company.[12]
