Multi Access

Wireless heterogeneous environment is becoming increasingly popular because of its ability to support multi access technologies, which keeps the mobile users always connected. The fourth generation (4G) of wireless environment consists of dissimilar technologies like Worldwide Interoperability for Microwave Access (WiMAX) and Long Term Evolution-Advanced (LTE-A). Coexistence of these standards presents technological challenges. Other challenges towards heterogenous 4G environment include coexistence of third generation (3G) and 4G and coexistence of Wireless Local Area Network (WLAN) and 3G/4G technologies. This chapter presents the technical overview of the 4G (WiMAX and LTE-A) standards and identifies the challenges and research issues (i.e., mobility management, network selection, handover, and Quality of Service [QoS]) toward a multi-access environment that consists of 3G, 4G, and WLAN technologies. The chapter also discusses future directions and some research solutions.

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN  with  advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.

Voice Communication

Voice Over Internet Protocol (VoIP) is a voice communication technology (voice) that uses IP which can be done electronically and in realtime. In building VoIP devices used such as IPPBX Server, IPPBX Gateway IP and other supporting devices such as mikrotik. To design VoIP generally implemented using a local area network (LAN) or a wireless local area network (WLAN). In this study, an analysis of the quality of VoIP network communication is to determine the problems caused by communication using VoIP, so that VoIP can be used to maximize the existing internet network. This VoIP network can save costs when communicating such as video communications or video conferencing.

<p><span>Wireless local area networks (WLAN) has been used recently due to their benefits which exhibits outstanding mobility with easier and faster configurations. The wireless local area network performance is much influenced by both network topology and hardware specifications and thus will impact the quality of service (QoS) parameters which are delay, load, and response time. This works estimated the performance of WLAN in enterprise WAN based on the OPNET modeler. Three scenarios have been suggested which are FDDI scenario, FDDI Hybrid Star scenario, and FDDI hybrid ring scenario involving web browsing (HTTP) and file transfer protocol (FTP). Hardware objects and software configurations kept the same for all proposed scenarios. Different types of links and topologies have been applied among WLAN subnets as well as the involved gateway has been changed to measure parameters of quality of services (QoS) for all scenarios used. The findings confirmed that the FDDI Hybrid Ring scenario presents better performance than the FDDI Hybrid Star Scenario and FDDI scenario in terms of WLAN delay, WLAN load, FTP download response time, and HTTP object response time.</span></p>

One of the changes in the field of telecommunications is the use of wireless technology. Wireless technology is applied to computer networks better known as Wireless Local Area Network (WLAN). Network coverage quality measurements can be seen from categories of delay or suspension, excess queues on the network, increased traffic, and output results. By using Wi-Fi Analyzer and Ekahau software we get the Quality of Service (QoS) value to see how good the coverage of the existing wireless network is. The result of the measurement is analyzed to get the adjustment of the wireless area coverage formula so that it can find the maximum range used as a reference in placing the ideal access point. The addition of access point points is done on all buildings where at some point the area can not be reached as a whole.

In this paper, a novel scheduling scheme for the Fourth Generation (4G)-Wireless Local Area Network (WLAN) network is proposed to ensure that end to end traffic transaction is provisioned seamlessly. The scheduling scheme is divided into two stages; in stage one, traffic is separated into Actual Time Traffic (ATT) and Non-Actual-Time Traffic (NATT), while in stage two, complex queuing strategy is performed. In stage one, Class-Based Queuing (CBQ) and Deficit Round Robin (DRR) are used for NATT and ATT applications, respectively to separate and forward traffic themselves according to source requirements. Whereas in the stage, two Control Priority Queuing (CPQ) is used to assign each class the appropriate priority level. Evaluation of the performance of the integrated network was done according to several metrics such as end-to-end delay, jitter, packet loss, and network’s throughput. Results demonstrate major improvements for AT services with minor degradation on NAT applications after implementing the new scheduling scheme.

The paper presents a Software Defined Radio (SDR) development platform with wideband tunable RF (Radio Frequency) front end. The platform is based on the SB3500 Multicore Multithreaded Vector Processor and it is intended to be used for a wide variety of communication protocols as: Time Division Duplexing/Frequency Division Duplexing Long Term Evolution (TDD/FDD LTE), Global Positioning System (GPS), Global System for Mobile/General Packet Radio Service (GSM/GPRS), Wireless Local Area Network (WLAN), Legacy Worldwide Interoperability for Microwave Access (WiMAX). As an example, we describe briefly the implementation of the LTE TDD/FDD communication protocol. As far as we know, this is the only LTE category 1 communication protocol entirely developed and executed in software (SW), without any hardware (HW) accelerators.
