TD-LTE: Another Network Technology for Mobile Telecommunication Evolution Haoliang JIAN Department of Electronics‚ University of York Heslington‚ York‚ YO10 5DD‚ UK hj639@york.ac.uk I. Abstract----Due to increasing demand of data traffic‚ the existing 3G network has nearly reach its capacity limitation. Carriers have paid more attention to the evolution scheme called LTE. According to different duplex mode‚ LTE has two different standards‚ which are TD-LTE and LTE-FDD separately. Although

Access which is known as WiMAX technology and its usage. It will also explain that what the need for producing such technology was and some of the applications such as Triple Play and WiMax Backhaul. What is special in WiMAX and whether it is better than WiFi or not? What are the advantages and the disadvantages of WiMax? I will also explain that what makes it different from Wi-Fi regarding coverage‚ expenses and deployment. Some of the enhancements and failures cases with WiMax are also presented.

Question #1 (a)Requirements for 4G & challenges: 4G is fourth generation standard for mobile phones and telecommunication. It is preceded by 3G. 4G designer has been facing some technical challenges against the requirements. Yes‚ 4G can meet all requirements if designer overcome the challenges. Data in 4G traffic is centric‚ data traffic channel increase instead of voice traffic channels. In wireless link user demand for services with the implementation of Asymmetric Digital Subscriber Line

History of Long Term Evolution (LTE) The Third Generation Partnership Project (3GPP) started on the work of Evolution of 3G Mobile System at RAN Evolution Work Shop on November 2004 in Toronto‚ Canada. They opened a work shop to all interested organization and interested parties. Proposals on evolution of Universal Terrestrial Radio Access Network (UTRAN) were presented there. High level requirements such as reduced cost per bid‚ flexibility of existing and new frequency bands‚ simplified architecture

WiMAX Network Design Part III in a series on how to plan a city-wide wireless WiMAX network. Once a municipality or operator has considered the business model and financial aspects of the WiMAX network and a comprehensive initial site survey has been completed‚ a preliminary design is required. The design will leverage the assets and information gained from the site survey and allow the engineer to make a cost effective design choice in terms of equipment and architecture. A comprehensive

What is WiMAX? WiMax is a wireless digital communications system‚ also known as IEEE 802.16‚ that is intended for wireless "metropolitan area networks". WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations‚ and 3 - 10 miles (5 - 15 km) for mobile stations. In contrast‚ the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m). With WiMAX‚ WiFi-like data rates are easily supported‚ but the issue of

Protocols stack 3.1.3 1.INTRODUCTION 1.1 Background The Internet protocols are the world’s most open system protocol suite because they can be used to communicate across any set of interconnected networks and are equally well suited for LAN and WAN communications. The Internet protocol consists of a suite of communication protocols‚ of which the two best known are TCP (Transmission Control Protocol) and IP (Internet Protocol). The IP suits not only
