    Orthogonal Frequency Division Multiple Access : Is it the Multiple Access System of the Future? Srikanth S., Kumaran V. , Manikandan C., Murugesapandian AU-KBC Research center, Anna University, Chennai, India Email: [email protected] Abstract There is significant interest worldwide in the development of technologies for broadband cellular wireless (BCW) systems. One of the key technologies which is becoming the de- facto technology for use in BCW systems is the orthogonal frequency division multiple access (OFDMA) scheme. In this tutorial article, we discuss the reasons for the popularity of OFDMA and outline some of the important concepts which are used in OFDMA as applied to BCW systems. We shall use the IEEE 802.16 based WiMAX standards for highlighting some of the significant ideas in the practical use of OFDMA systems. 1. Introduction Broadband Cellular Wireless (BCW) systems are expected to be rolled out in the near future to satisfy demands from various segments. As demand for mobile services continuous to grow worldwide system vendors and cellular operators have noticed the enormous popularity of 2nd generation mobile cellular systems and are keen to extend this trend to BCW systems. Several challenges exist in the development and deployment of BCW systems and research work addressing these challenges is ongoing in several labs around the world. The orthogonal frequency division multiple access (OFDMA) based systems are being adopted for use in different flavors of BCW systems [1]. The IEEE 802.16d and 802.16e standards which are popularly known by the industry forum name WiMAX are being considered for BCW systems and are the first standards to use the OFDMA technique [2].

In short, deploying 802.11ax-based spectrum into time-frequency resource units (RUs). In this paper, we aim at designing an 802.11ax-based dense WiFi network dense WiFi network is both crucial and urgent. There are two to provide WiFi services to a large number of users within a main factors that affect the network performance. The first given area with the following objectives: (1) to minimize the one is the AP placement. The second one is resource (such as number of access points (APs); (2) to fulfil the users’ throughput power, channel, and RU, etc.) assignment for the APs/stations. requirement; and (3) to be resistant to AP failures. We formulate Furthermore, users demand continuous WiFi services even the above into a joint AP placement and power-channel-RU assignment optimization problem, which is NP-hard. To tackle under AP’s failures [4]. Unfortunately, there is little research this problem, we first derive an analytical model to estimate each on joint AP placement and resource assignment for 802.11ax- user’s throughput under the mechanism of OFDMA and a widely based dense WiFi network with quality of service (QoS) used interference model.

In industrial net- works, manufacturing processes require hard real-time communication where the latency is less than 1ms. Time-sensitive networking (TSN) technology over Ethernet already supports deterministic de- livery for real-time communication. However, TSN technologies over wireless networks are currently in their initial development stage. Therefore, this study presents an overview of TSN research trends in wireless communications. This paper focuses on 5G networks and IEEE 802.11. We summarize standardization trends for TSN in 5G networks and introduce the TSN technologies for 802.11-based WLAN. Then, we introduce the integration scenario of 5GS with WLAN. This study provides insights into wireless communication technologies for wireless TSN.

Although these two techniques have in cellular networks (see Table I), their joint optimization in been intensively studied in cellular networks, their joint optimiza- Wi-Fi networks remains scarce because OFDMA is introduced tion in Wi-Fi networks has been rarely explored as OFDMA was introduced to Wi-Fi networks for the first time in 802.11ax.

Given that marriage of these two techniques in Wi-Fi networks creates both cellular and Wi-Fi networks have different PHY (physical) opportunities and challenges in the practical design of MAC- and MAC (medium access control) layers, and that base layer protocols and algorithms to optimize airtime overhead, stations (BSs) and APs have very different computational spectral efficiency, and computational complexity.
