Quick and Dirty Aggregate Queries on Low-Power WANs

The 868 MHz ISM band limits the use of a device to 1% of the time on air. LoRaWAN specifies that each time a message is send in one ISM subband, the device must wait the remaining time of the duty cycle in that band before resending. Specifically, we first design a duty-cycle spectrum sharing framework, which allows an LTE system to share the spectrum with a WiFi system by using time sharing. After that, we develop deep reinforcement learning (DRL)-based algorithms to learn WiFi traffic demands by analyzing WiFi channel activity, e.g., the idleness/business of WiFi channels, which can be observed by the LTE system via IoT applications which require more frequent communications will be better served by NB-IoT, which has no duty cycle limitations operating on the licensed spectrum. In March 2019, the Global Mobile Suppliers Association announced that over 100 operators have deployed/launched either NB-IoT or LTE-M networks.

So if Wi-Fi were alone on the channel, it would get 100% of the airtime.

LTE-U differs from WiFi, the predominant technology used in unlicensed spectrum in that it utilizes a duty cycle mode for accessing the spectrum and allows for a more seamless integration with LTE deployments in licensed spectrum.
