LPWAN

Low-power wide-area network

Low-power wide-area network

Type of wireless telecommunication network

Not to be confused with Low-power personal-area network.

A low-power, wide-area network (LPWAN or LPWA network) is a type of wireless telecommunication wide area network designed to allow long-range communication at a low bit rate between IoT devices, such as sensors operated on a battery.

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.

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.

Attributes

  1. 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. Power: LPWAN manufacturers claim years to decades of usable life from built-in batteries, but real-world application tests have not confirmed this.[1]

Platforms and technologies

Some competing standards and vendors for LPWAN space include:[2]

  • 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.[3]
  • Sigfox, UNB-based technology and French company.[4]
  • LoRa is a proprietary, chirp spread spectrum radio modulation technology for LPWAN used by LoRaWAN, Haystack Technologies, and Symphony Link.[5][6]
  • MIoTy, implementing Telegram Splitting technology.
  • Weightless is an open standard, narrowband technology for LPWAN used by Ubiik
  • ELTRES, a LPWA technology developed by Sony, with transmission ranges of over 100 km while moving at speeds of 100 km/h.[7]
  • IEEE 802.11ah, also known as Wi-Fi HaLow, is a low-power, wide-area implementation of 802.11 wireless networking standard using sub-gig frequencies.[8]

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 uses unlicensed 2.4GHz spectrum.[15][16] RPMA is used in GE's AMI metering.[17]
  • Byron, a direct-sequence spread spectrum (DSSS) technology from Taggle Systems in Australia.[18]
  • Wi-SUN, based on IEEE 802.15.4g.[19]
