Several radio technologies such as IEEE 802.11 and Bluetooth operating in the 2.4 GHz
license-free ISM frequency band when present in the same environment leads to signal …

IEEE 802.11 ah (also known as WiFi Halow) is a new WiFi standard for sub-l GHz
communications intended to address key challenges of the Internet of Things. IEEE 802 …

Due to its usefulness and wide deployment, IEEE 802.11 has been the subject of numerous
studies, but still lacks a complete analytical model. Hidden terminals are common in IEEE …

A new accurate analysis model of the IEEE 802.11 DCF is presented. The analysis model is
based on a close observation of the IEEE 802.11 DCF behavior. We observe that an infinite …

Directional antennas have been introduced to improve the performance of 802.11 based
wireless networks. Station equipped with directional antennas can beamform data in a …

It is well-known that the values of IEEE 802.11 MAC parameters directly affect the utilization
of the channel capacity and link layer throughput as well as higher layers performance. This …

One interesting problem regarding wireless local area network (WLAN) ad-hoc networks is
the effective mitigation of hidden nodes. The WLAN standard IEEE 802.11 provides request …

We develop an analytical medium access control (MAC) and physical (PHY) cross-layer
model to calculate the link budget and to estimate the cell coverage of IEEE distributed …

This paper presents a measurement study of interference from six common devices that use
the same 2.4 GHz ISM band as the IEEE 802.11 protocol. Using both controlled experiments …

An IEEE 802.11 af indoor trial experiment has been conducted in the Ofcom pilot program of
the United Kingdom. This paper describes an indoor propagation characterization and …
