frequency allocation but more specifically within a context of mobile networks and the mathematics involved. We will focus more towards the issue of frequency allocation/assignment as well as touching base on the historical context of the issue and it 's influence of our approach towards the problem today. In a basic reference, modern day communication uses the electromagnetic spectrum and every industry from aviation to television networks requires the use of this spectrum. Given its limits, the government

2.2 LPS Classification Due to their diversity, LPS schemes can be categorized from different perspectives .The classification could be based on various criteria like methodology, dependency on equipment’s, operating scenarios, targeted users and outputs. Here we categorize indoor localization systems along three dimensions. First, we consider the output of a localization system which is usually generalized as locations or positions, but actually could be divided into different groups. Most

nationwide 4G LTE network where you can talk and surf simultaneously, all without an annual contract. The Cricket Wireless brand name has been in the market for more than fifteen years and is widely recognized in many parts of the country. The weaknesses of Cricket Wireless come from its limited availability for international coverage and roaming capabilities. Also, the phone selection is very basic and/or one dimensional compared to the latest apple products and other cellular devices. To readdress

Mobile Communication from 1G to 4G Ajit Singh Grewal GEORGE MASON UNIVERSITY Fairfax, Virginia, USA Abstract The evolution of mobile telephone system can be classified into different generation based on the level of maturity in technology. This classification does not depend on any standardized facts. The purpose of this paper is to provide the history of mobile communication and provide an overview of 4G and its features, architecture, key technologies and challenges. Introduction: From 1G (First

With a proper market research, this technique will allow any company to live another day in the market or even live more years. Verizon wireless, the nation’s largest and leading wireless network service provider, according to National Mobile Network Performance Rankings (usatoday, 2015), has been part of many market researches throughout the years. One of their most iconic and trend leading decisions was to allow customers to keep their wireless numbers when they chose

The next major step in mobile phone history was in the mid-eighties with the First generation (1G) fully automatic cellular networks released. The first ever mobile phone approved by the Federal Communications Commission in the USA was the Motorola DynaTac in 1983 (USswitch). The benefits of the mobile phone are simple and apparent. The mobile phone provides the convenience

Assessment task 1 The mobile industry is made up of four main mobile networks which all compete together to serve the best mobile experience to its customers. Three, EE, Vodafone and O2 all provide the UK with a cellular signal and a mobile broadband connection to allow an extra flow of communication around the UK. Another company, Ofcom, ensures the UK has these services by providing telecom masts which are used by the four main mobile networks and by emergency services such as Airwave. (Ofcom, 2016) Airwave

Enhance the network reliability and reduce the cost efficiency always been a major challenge for the cellular network operator and there is no magic solution to that demand [14]. With evolution of mobile network, the capacity requirement of transport network from the core raises significantly [18]. The major backhaul challenges that mobile network operator had to deal with up to 4G network includes capacity, availability, deployment cost, and long distance reach [16]. But, 5G network will interconnect

layer. The transmit power is allocated to spatial layer under the total base station power constraint and the per base station power constraint Keywords : LTE A, CoMP, UE, MIMO, 3GPP Introduction In order to maintain the competitiveness of the 3GPP cellular system, Long Term Evolution (LTE), is developed. For downlink transmission the technique selected is Orthogonal frequency division multiple access (OFDMA). In this time and frequency resources are reused in adjacent cells, inter cell interference

ABSTRACT Mobile positioning technology has become an important area of research, for emergency as well as for commercial services. Mobile positioning in cellular networks will provide several services such as, locating stolen mobiles, emergency calls, different billing tariffs depending on where the call is originated, and methods to predict the user movement inside a region. The evolution to location-dependent services and applications in wireless systems continues to require the development of
