wifi-wireless fidelity 2020


Wi-Fi is the name of a wireless networking technology that uses radio waves to provide wireless
high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for “wireless fidelity,”

DRAIM: A novel delayconstraint and reverse auction-based incentive mechanism for WiFi offloading

Offloading cellular traffic through WiFi Access Points (APs) has been a promising way to relieve the overload of cellular networks. However, data offloading process consumes a lot of resources (eg, energy, bandwidth, etc.). Given that the owners of APs are rational and

FingerDraw: Sub-wavelength Level Finger Motion Tracking with WiFi Signals

This paper explores the possibility of tracking finger drawings in the air leveraging WiFi signals from commodity devices. Prior solutions typically require user to hold a wireless transmitter, or need proprietary wireless hardware. They can only recognize a small set of pre-defined hand

Joint Access Point Placement and Power-Channel-Resource-Unit Assignment for 802.11 ax-Based Dense WiFi with QoS Requirements

IEEE 802.11 ax is a promising standard for the next-generation WiFi network, which uses orthogonal frequency division multiple access (OFDMA) to segregate the wireless spectrum into time-frequency resource units (RUs). In this paper, we aim at designing an 802.11 ax
