LPWAN
• 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]
• 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]
• LoRa, proprietary, CSS modulation technology used for LPWAN patented by Semtech by LoRa Alliance used by LoRaWAN and
Symphony Link.[17]
• Weightless, a set of communication standards from the Weightless SIG.
• UNB, Ultra Narrow Band, modulation technology used for LPWAN by various companies including Telensa,[18] NWave,[19] Weightless-
N[20] and Sigfox.[21]
