Sometimes your Wi-Fi connection encounter problems, but is turning up the transmit power the solution?

If you’re struggling to get good Wi-Fi coverage in your home, it would seem intuitive to turn up the transmit power of your Wi-Fi router. Before you do, read this.

The proliferation of IEEE 802.11 or WiFi networks, and the explosive growth in traffic demands call for solutions to maximize the capacity of WiFi networks. Hence, maximizing the spatial reuse of WiFi networks is critical as doing so allows multiple concurrent transmissions. In this respect, a critical network parameter, Clear Channel Assessment (CCA) threshold, plays a vital role as it dictates whether a node is allowed to transmit after sensing the channel. In this paper, we propose to use Deep Q-network (DQN) under two learning patterns to select the CCA threshold of devices. We further con...

To most people, all Wi-Fi might seem the same. As long as your router is properly connected to the internet, a network is a network, allowing you to stream Netflix, check Facebook, send emails, and anything else you've

Abstract We consider a Radio Frequency (RF)-charging network where sensor devices harvest energy from a solar-powered Hybrid Access Point (HAP) and transmit their data to the HAP. We aim to optimize the power allocation of both the HAP and devices to maximize their Energy Efficiency (EE), which is defined as the total received data (in bits) for each Joule of consumed energy. Unlike prior works, we consider the case where both the HAP and devices have causal knowledge of channel state information and their energy arrival process. We model the power allocation problem as a Two-layer Markov Dec...
