LPWAN

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]
