Discontinuous Reception (DRX) is the standard cellular technique where the device wakes periodically to check for pages rather than listening continuously. Standard DRX cycles are 1.28 seconds in LTE. Extended DRX (eDRX) extends the cycle to seconds, minutes, or even tens of minutes, dramatically reducing the device's paging-cycle energy. NB-IoT eDRX cycles run from 20.48s up to 10485.76s (the longest, about 2.91 hours) in the standardized set: 20.48s, 40.96s, 81.92s, 163.84s, 327.68s, 655.36s, 1310.72s, 2621.44s, 5242.88s, 10485.76s. LTE-M eDRX cycles span 5.12s up to 2621.44s (about 44…
