In-Band Full-Duplex (IBFD) is a technique that enables a wireless node to simultaneously transmit a signal and receive another on the same frequency band. Thus, IBFD wireless systems can theoretically provide up to twice the channel capacity compared to conventional Half-Duplex (HD) systems. In order to study the feasibility of IBFD networks, reliable models are needed to capture anticipated benefits of IBFD above the physical layer (PHY). In this paper, an accurate analytical model based on Discrete-Time Markov Chain (DTMC) analysis for IEEE 802.11 Distributed Coordination Function (DCF) with IBFD capabilities is proposed. The model captures all parameters necessary to calculate important performance metrics which quantify enhancements introduced as a result of IBFD solutions. Additionally, two frame aggregation schemes for Wireless Local Area Networks (WLANs) with IBFD features are proposed to increase the efficiency of data transmission. Matching analytical and simulation results with less than 1% average errors confirm that the proposed frame aggregation schemes further improve the overall throughput by up to 24% and reduce latency by up to 47% in practical IBFD-WLANs. More importantly, the results assert that IBFD transmission can only reduce latency to a suboptimal point in WLANs, but frame aggregation is necessary to minimize it. Finally, energy-efficiency is compared for both HD and IBFD networks. In comparison with the HD counterpart, IBFD systems can deliver superior energy efficiency for a given traffic scenario at the cost a higher power consumption.

Future networks require a high degree of flexibility over wide areas to enable many services that require higher quality wireless networks such as remote control of cars and remote surgery. Therefore, the network technology must combine high capacity, low latency, and flexibility. To deal with these requirements, we developed Software-Defined Radio over Fiber (SD-RoF), which is an architecture that tightly couples light and radio at a low cost. SD-RoF offers the following two key features: elastic wireless service and elastic bidirectional passthrough. The elastic wireless service provides users with access to wireless services that they need at any time in any place. The elastic bidirectional passthrough connects two remotely located points via RoF through radio waves and enables allowing for bidirectional radio communication between devices at each location. In this study, we design and prototype implementation of SD-RoF, and conduct a basic evaluation of the implemented circuit and demonstration experiments on elastic bidirectional passthrough. Through demonstration experiments, we found the feasibility and the challenges of SD-RoF. In addition, the deployment of SD-RoF, application scenarios, and operational issues are discussed.

Current 4G - the fourth-generation wireless communication, which exists in most countries represents an advance of the previous 3 generation wireless communication. However, there are some challenges and limitations, associated with an explosion of wireless devices, which cannot be accommodated by 4G. Increasing the proliferation of smart devices, the development of new multimedia applications and growing demand for high data rates are among the main problems of the existing 4G system. As a solution, the wireless system designers have started research on the fifth-generation wireless systems. 5G will be the paradigm shift that could provide with ultra-high data rate, low latency, increase of the base station capacity and improved quality of services. This paper will be the review of the changes through the evolution of existing cellular networks toward 5G. There will be represented a comprehensive study associated with 5G, requirements for 5G, its advantages, and challenges. We will explain the architecture changes – radio access network (RAN), air interfaces, smart antennas, cloud RAN and HetNet. Furthermore, there will be discussed about physical layer technologies, which include new channel modes estimation, new antenna design, and MIMO technologies. Also, we will discuss the MAC layer protocols. We will look at three kinds of technologies: heterogeneous networks, massive multiple-input, and output, millimeter-wave. Finally, there will be explained the applications, supported by 5G, new features, various possibilities, and predictions.
