CAREER EPISODE – 1 MTNL India BSC (Base Station Controller) traffic migration CE 1.1 Introduction:- Duration : Jan 2008 – June 2008 Geographic Location : Mahanagar Telephone Nigam Limited, Connaught Place, New Delhi, India Position Held : Engineering Student (College project) In final year of my bachelor’s degree I got the opportunity to work with MTNL (Indian Government’s owned telecom company) on BSC (Base Station Controller) migration as part of training and project. The migration involved

So, for example, Vodafone uses extra 1 million gallons of gas per day to provide power their network. The above example gives us an idea of how the energy is consumed by the information technology. They are increasing energy costs with larger base station site densities which leads to increase in energy price. Many companies have decided to reduce carbon emissions, for example Vodafone has set a target to reduce it CO2 emissions by approximately 50% by 2020. From an operators perspective, lowering

the base stations through which the terminal access takes place. In order to overcome and solve this problem Mobile Virtual Centre of Excellence (VCE) has performed a project named Green Project in the year 2009 and the main aim of this project is to overcome all the problems and to develop a process which is going to save energy in future wireless systems. This paper deals with the technical parts of the project and details several other current energy consumption models in the base station devices

technology Does works on a system geographically its seperated zones are called cells. Majority of the cells have its own base station that both and it receivs and it also emits the radio waves. When the call is then placed from the cell phone and then the signal is sent from the cell phones antenna to one of the cell’s base station called the antenna. Once the base station transfers the calls to the switiching center the call is then transferred to another cell phone. Once one of the RF channel

certain (USDA, 2009). In this paper I will be addressing the following scenario (Case 4): A mobile phone base station was installed near a neighborhood in order to provide a better service coverage in 2008. Over the past 5 years, the local residents complained of headache, memory loss, dizziness, tremors, depressive symptoms, and sleep disturbance. They are concerned that the station has caused neuropsychiatric problems and some changes in the performance of neurobehavioral functions. They are

1. Introduction A Macrocell user operating in the same band as femtocell users may cause unacceptably high interference levels, if it is close to the femtocell base station supporting the aforementioned femtocell users, and far away from its own macrocell base station. Additionally, the fact that femtocells can be deployed in an ad hoc fashion anywhere within a macrocell, and can be removed as easily, adds to the critical importance of interference management. Notwithstanding the importance of

BTS ID, TOA of signals, and so on that we discuss later. Depending on past information about the MS, a set of BS’s could be used to page the MS, and directly or indirectly obtain the location parameters. These are sometimes called Geolocation base stations (GBSs). Once this information is collected, the location control center can determine the location of the mobile with certain accuracy and convey this information to the service provider. The service provider will then use this information to visually

Difference between GSM AND CDMA . This term paper is a comparison (difference) between two technologies which brought revolution in the field of mobile communication i.e GSM and CDMA . Firstly in the term paper , history of both of these technologies , GSM and CDMA is introduced along with their brief terminology . After the history construction , working and its application is discussed and compared . Finally the main difference in both the technologies i.e GSM and CDMA is summarized to

Mobile phone exposure and carcinogenesis Brain cancer is the most frightening hazard of mobile phone use. The International Agency for Research on Cancer (IARC) classified RF fields as “possibly carcinogenic to humans,” in 2002 in spite of limited evidence from human and animal studies (IARC, 2002). The relation between mobile phone radiation exposure and cancer are justified. Muscat et al. (2000) showed that a relationship exists between mobile phone use and meningioma or glioma. A meta-analysis

featured, short range mobile phone base stations used to complement mobile phone services from larger macrocell towers. These range from very compact residential femtocells to larger equipment used inside offices or public spaces. They offer excellent mobile phone coverage and data speeds at all the places. Femtocells have been developed for 3G and also the newer 4G/LTE radio technologies. III. DEFINITION OF A FEMTOCELL Femtocells, also known as ‘home base stations’, are small low power cellular network
