LoRa Link-budget and Sensitivity Calculations – Example Explained !

January 30, 2019

LoRa is a proprietary spread spectrum modulation scheme that is derivative of Chirp Spread Spectrum modulation (CSS) and which trades data rate for sensitivity within a fixed channel bandwidth. It implements a variable data rate, utilizing orthogonal spreading factors, which allows the system designer to trade data rate for range or power, so as to […]

LoRa – Device Re-activation Call Flow (Rejoin Procedure)

January 30, 2019

LoRa Technology supports the handling and configuration of rejoin-requests for LoRa End Devices. Using a rejoin-request, a device is able to request the network-server to re-activate, without being ‘disconnected’ until receiving the activation. In other words, when it doesn’t receive a new activation, the device will continue to use the old security context. With the […]
