Data Rate | Adaptive (ADR) Startup value is SF12BW125 SF12 uses the longest time-on-air, maximizing the wireless communication range. Adaptive Data Rate (ADR) is a mechanism for optimizing data rates, airtime and energy consumption in the network. The ADR mechanism controls the following transmission parameters of an end device.
ADR can optimize device power consumption while ensuring that messages are still received at gateways. When ADR is in use, the network server will indicate to the end device that it should reduce transmission power or increase data rate. End devices which are close to gateways should use a lower spreading factor and higher data rate, while devices further away should use a high spreading factor because they need a higher link budget. ADR should be enabled whenever an end device has sufficiently stable RF conditions. This means that it can generally be enabled for static devices. If the static end device can determine that RF conditions are unstable (for example, when a car is parked on top of a parking sensor), ADR should (temporarily) be disabled. Mobile end devices should be able to detect when they are stationary for a longer times, and enable ADR during those times. End devices decide if ADR should be used or not, not the application or the network |
