Low-Power Wide-Area Network (LPWAN) or Low-Power Network (LPN) is a type of wireless telecommunication 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]

Platforms and technologies

  • Haystack, a DASH7 Mode 2 development framework for low power wireless networks by Haystack Technologies.[3]
  • LoRaWAN,[4] Long Range Wide Area Network (WAN), from the LoRa Alliance. On 16 June 2015 version 1.0 of the LoRaWAN specification was released.[5] The first LoRa Alliance certified radio module with a maximum output power of 19 dBm is the iM880B-L by IMST GmbH.
  • NarrowBand IoT, (NB-IOT), standardization effort by 3GPP for a LPWAN used in cellular networks,[6] that evolved from Huawei's NB-CIoT effort.[7]
  • LTE Advanced for Machine Type Communications (LTE-MTC), an evolution of LTE communications for connected things by 3GPP.[8]
  • NB-Fi Protocol, from WAVIoT.[9][10]
  • NWave, proprietary technology that also forms the basis of the Weightless protocols[11][12]
  • RPMA, Random Phase Multiple Access, technology from Ingenu,[13] formerly known as On-Ramp Wireless.
  • Senet, public LoRaWAN provider in North America.[14]
  • Symphony Link, LoRa-based platform from Link Labs.[15]
  • Sigfox, UNB-based technology and French company.
  • ThingPark Wireless, platform from Actility (based on LoRaWAN specification).[16]
  • Weightless, a set of communication standards from the Weightless SIG.
  • LoRa, proprietary, CSS modulation technology used for LPWAN patented by Semtech by LoRa Alliance used by LoRaWAN and Symphony Link.[17]
  • UNB, Ultra Narrow Band, modulation technology used for LPWAN by various companies including Telensa,[18] NWave,[19] Weightless-N[20] and Sigfox.[21]
