LoRaWAN is a media access control (MAC) protocol for wide area networks. It is designed to allow low-powered devices to communicate with Internet-connected applications over long range wireless connections. As a Low Power Wide Area Network (LPWAN) protocol, it is particularly applicable to the Internet of Things. It emphasizes secure bi-directional communication, mobility, and localization services to provide simple, seamless interoperability among smart "Things".
LoRa spreads communication between end-devices and gateways across multiple frequency channels and data rates. The spread spectrum technology uses data rates ranging from 0.3 kbps to 50 kbps to prevent communications from interfering with each other, and creates a set of "virtual" channels that increase the capacity of the gateway. To maximize both the battery life of the end-devices and the overall network capacity, the LoRa network server manages the data rate and RF output for each end-device individually through an adaptive data rate (ADR) scheme. LoRa also addresses the need for security by providing encryption at the network level, application level, and device level through the use of a unique network key (EUI64), a unique application key (EUI64), and a device-specific key (EUI128).
About the speaker:
Mr Gagnon have sent his live working with something that no one can ever, see, feel or touch, called; Radio Waves. From his youg age playing with rabbit ear antenna to maximise TV signal strength, to jamming missiles afer completing a Master degree in microwave circuit, antenna and radar, Mr Gagnon made a full carriere in RF. In 1995 he founded Auratek using RF signal in the ground to detect human presence, then in 2005 he founded KG Spectrum using microwave signal to remotly monitor a human breathing and hearth rate profile, then in 2013 he install the first LPWA (Low Power Wind Area) based LoRa IoT system in Canada, this time to monitor municipality sewer overflow, returning back using RF deep into the soil.
