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.
There are a number of competing standards and vendors in the LPWAN space, the most prominent of which include:
LoRa, proprietary, CSS modulation technology used for LPWAN patented by Semtech by LoRa Alliance used by LoRaWAN, Haystack Technologies, and Symphony Link.On 16 June 2015 version 1.0 of the LoRaWAN specification was released.
Haystack, a DASH7 Mode 2 development framework for low power wireless networks by Haystack Technologies.
LTE Advanced for Machine Type Communications (LTE-MTC), an evolution of LTE communications for connected things by 3GPP.
MySensors, DIY Home Automation framework supporting LoRa radios.
NarrowBand IoT, (NB-IOT), standardization effort by 3GPP for a LPWAN used in cellular networks, that evolved from Huawei's NB-CIoT effort.
