LPWAN

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.

Technology attributes[edit]

  1. Long range: The operating range of LPWAN technology varies from a few kilometers in urban areas to over 10 km in rural settings. It can also enable effective data communication in previously infeasible indoor and underground locations.
  2. Low power: Optimized for power consumption, LPWAN transceivers can run on small, inexpensive batteries for up to 20 years
  3. Low cost: LPWAN's simplified, lightweight protocols reduce complexity in hardware design and lower device costs. Its long range combined with a star topology reduce expensive infrastructure requirements, and the use of license-free or licensed bands reduce network costs.

Platforms and technologies[edit]

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

  • DASH7, a low latency, bi-directional firmware standard that operates over multiple LPWAN radio technologies including LoRa.
  • Chirp spread spectrum based
  • Sigfox, UNB-based technology and French company.[5]
  • Weightless is an open standard, narrowband technology for LPWAN used by Ubiik
  • Wize is an open and royalty free standard for LPWAN derived from the European Standard Wireless Mbus.[8]

Ultra-narrow band[edit]

Ultra Narrowband (UNB), modulation technology used for LPWAN by various companies including:

  • Sigfox, UNB-based technology and French company.[9]
  • Telensa[10] A Cambridge-based company using UNB-based technology to connect and control streetlights and other city infrastructure.
  • Nwave,[11] proprietary technology developed in cooperation with MIT. Its first release without error correcting codes also forms the basis of the Weightless-N open protocol.[12][13]
  • Weightless, a set of communication standards from the Weightless SIG.[14]
  • NB-Fi Protocol, developed by WAVIoT company.[15]

Telegram splitting[edit]

Telegram splitting is a standardized LPWAN technology in the license-free spectrum.

  • MIOTY, telegram-splitting technology standardized by ETSI (TS 103 357).
