VoWiFi Cell Capacity Estimation using IEEE 802.11ax

2021 28th International Conference on Telecommunications (ICT), 2021
The IEEE 802.11 standard is commonly used to provide wireless networking capabilities for different applications. Although the format was designed mainly to provide data transmission capability, it also became a common medium for speech communication. The reasons are twofold: extensive Wireless Local Area Network (WLAN) connectivity and the low cost of

UL-MU Transmissions in IEEE 802.11ax Networks

2020 IEEE International Conference on Consumer Electronics (ICCE), 2020
In IEEE 802.11ax networks, multiple uplink wireless-connectivity services are supported by an uplink multiuser multiple-input and multiple-output (MU-MIMO) technique. In this study, we propose a method for uplink multi-user (UL-MU) transmissions in IEEE 802.11ax networks. In the proposed method, stations are clustered on the basis of their transmission

Uplink Resource Allocation in IEEE 802.11ax

ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019
One of the notable features of the upcoming Wireless Fidelity (Wi-Fi) standard—namely, IEEE 802.11ax—is the use of Multi-User Orthogonal Frequency Division Multiple Access (MU-OFDMA). MU-OFDMA facilitates multiple users to transmit simultaneously in smaller sub-channels (a.k.a.

An IEEE 802.11ax Interference-Aware MAC Queue

2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020
The first wave of IEEE 802.11ax capable devices have already hit the market, aiming at enhancing the Quality of Experience (QoE) for the users in dense deployments, by enabling novel features to improve throughput and spectrum efficiency. One of these features is Spatial Reuse (SR) mechanism, which is introduced for coping with the exposed node problem.

High Efficiency WLANs IEEE 802.11ax Performance Evaluation

2018 International Conference on Control, Automation and Diagnosis (ICCAD), 2018
Users of wireless networks, require mostly speed and strength when it comes to connectivity. However, the increasing number of devices, diversity of traffic, and the density of networks, makes it difficult to maintain a reliable and efficient connection. Hence, the need for High Efficiency WLAN, often referred to as IEEE 802.llax.
