Abstract
Wireless communication range for certain devices (e.g., a smartphone, smart watch, wearable device, augmented reality glasses, etc.) can be limited by regulatory transmit power constraints, such as for specific absorption rate, which may contribute to unreliable connections at a network edge. Systems and methods are described for dynamically managing a transmitter's duty cycle and instantaneous power. For example, a link assessment module can monitor wireless conditions and, upon detecting a power-limited state, a duty cycle modulator can reduce the transmitter's active time using techniques such as inter-frame space elongation or control frame mechanisms. This reduction can create a power budget within time-averaged regulatory limits. An adaptive power controller can then reallocate this budget to increase the instantaneous transmit power for data frames. This approach may improve the uplink link budget, potentially extending the effective communication range and improving connection stability in power-limited scenarios.
