LPWAN

From HandWiki
Short description: Type of wireless telecommunication wide area network

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

  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

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.
  • Wize is an open and royalty free standard for LPWAN derived from the European Standard Wireless Mbus.[5]
  • Sigfox, UNB-based technology and French company.[6]
  • LoRa is a proprietary, chirp spread spectrum radio modulation technology for LPWAN used by LoRaWAN, Haystack Technologies, and Symphony Link.[7][8]
  • MIoTy, implementing Telegram Splitting technology.
  • Weightless is an open standard, narrowband technology for LPWAN used by Ubiik

Ultra-narrow band

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

Others

  • DASH7 Mode 2 development framework for low power wireless networks, by Haystack Technologies.[12] Runs over many wireless radio standards like LoRa, LTE, 802.15.4g, and others.
  • LTE Advanced for Machine Type Communications (LTE-M), an evolution of LTE communications for connected things by 3GPP.[13]
  • MySensors, DIY Home Automation framework supporting different radios including LoRa.
  • NarrowBand IoT (NB-IoT), standardization effort by 3GPP for a LPWAN used in cellular networks .[14]
  • Random phase multiple access (RPMA) from Ingenu, formerly known as On-Ramp Wireless, is based on a variation of CDMA technology for cellular phones, but is purpose-built to use unlicensed 2.4GHz spectrum..[15][16] RPMA is used in GE's AMI metering.[17]
  • Taggle Byron. A Direct Sequence Spread Spectrum (DSSS) technology from Taggle Systems in Australia. "How Taggle is spreading LPWAN across Australia"
  • Wi-SUN, based on IEEE 802.15.4g.[18]
