Cellular network

Abstract With the development of mobile devices and web applications, people tend to access data, audio, picture and video from their mobile devices anywhere and anytime, thus, wireless mobile telecommunication becomes more and more important. Cellular network technology is the basis for the wireless mobile telecommunication. And the generation is used to describe the development history of wireless mobile telecommunication standard and technology, from first generation (1G) to fifth generation (5G)

of having a purely fixed line network vs. a purely cellular network. When making this decision there are several things to consider, the most important is what this network is going to be used for. I am going to first go over the fixed line network then follow up with the cellular network. At the end of this paper I will do a recommendation to a new company that wants to open up a Skype- style service as to whether they should use a fixed line or a cellular network. Fixed line telephones

Handoff process enables a cellular system to provide such a facility by transferring an active call from one cell to another. Further, in addition to voice communication the use of many other services such as multimedia, e-mail and data services came into existence. Therefore to increase the capacity, the service area

concert halls, sports stadiums, and high-congestion traffic areas in metropolitan cities. [pic] Figure 1. Cellular phone cloning 5. Loop holes in Cell phone Networks • ESN/MIN data is NOT encrypted on the way to the MSC (Mobile Switching Centre) for further authentication. Thus, scanning the airwaves for this data if you wish to clone a phone. By changing ESN and MIN, the cellular carrier will accept the call and bill it to either a wrong account or provide service based on the fact that

Unit 1 Lab 1 Data on Fixed Line vs. Cellular Debate June 16, 2014 Debate the Pros and Cons to having a purely cellular network vs. having a purely fixed line network Pro 's: Cost: Most wireline phone companies charge more than what you 'd pay for most alternatives, and some are taxed more as well. There are some locations where getting new wired phoneservice is prohibitively expensive or even impossible. Long Distance and extra features like Call Waiting are normally included with alternative

and Optimization Algorithm for Cellular Networks Muhammad Umair, Waleed Bin Shahid, Masab Javed Abbasi, Department of Electrical Engineering Royal Institute of Technology (KTH) SE100-44 Stockholm, SWEDEN E-mail: mumair@kth.se, waleed.shahid@mcs.edu.pk , masab.abbasi-pc@telenor.com.pk Abstract— Frequency planning in ever growing cellular networks is an extremely arduous task. Any effort to lay down manual frequency plans promulgates inefficiency in the cellular radio systems. The extensive

Chapter 1 Introduction The cellular technology has developed a long way from its existence in the early 1980’s. In the past few decades it has grown into one of the biggest market with the rise of cell phone users, the cellular network providers and cell phone makers have grown in immense amount. Cellular technologies have evolved from first generation (1G), second generation (2G), third generation (3G) and to its current technology which is fourth generation (4G) which is also known as Long Term

Wireless communication has emerged as its own discipline over the past decades.From cellular voice telephony to wireless internet and data services,data service has profoundly impacted our lifestyle.After a decade of exponential growth today wireless network is one of the largest industry in the world. At the time of wirtting this close to 1 billoin people subscribe to cellular service,close to 200 billion gsm short message is exchanged every year.In response to this growth, a number of universities

significant difference charged by BSNL compared to the private players. All these situations BSNL could have controlled but it didn’t. STEPS TOWARDS CUSTOMER ORIENTATION AND FORAY IN CELLULAR SERVICES In 2000, mobile service has seen phenomenal growth. BSNL had to take step towards survival. It decided to launch its cellular service by April, 2002. But the launched delayed for few months. This resulted in loss of many prospective customer. CellOne (Post-paid) and Excel (Pre-paid) were launched in October
