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.

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.

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.
