Development Of Wireless Mobile Telecommunication Essay

Cellular communications is such a large aspect of today’s industries, and with the number of consumers already with cell phones drastically increasing all the time, it is good to think about the future, and maybe making the customers you already have, happy and content. There are only so many “new” customers you can gain in today’s market. Phone

A networking framework in which devices communicated with each other by first going through an Access Point (AP). In infrastructure mode wireless devices can communicate with each other or can communicate with a wired network. With one AP is connected to wired network and a set of wireless stations it is referred to as a Basic Service Set (BSS). An extended service set (ESS) is a set of two or more BSSs that from a single sub network. Most corporate wireless LAN operates in infrastructure mode because they require access to the wireless LAN in order to use services such as file services or printers. A cellular network or mobile network is a wireless infrastructure base network distributed over land areas called cells.

In present, 4G is applying with IMT-Advanced and bring more convenience to people. The evolution of mobile phone infrastructure is developing at an incredible rate. No one can accurately predict the trend of its

Both Mobile and Wireless network, in today’s world the current use of both concepts has

Wireless technology means that data is sent from one computer to another through a wireless connection. Mobile technology is the way that communicates tasks which are performed. Computing on mobile technology devices, such as laptops, notebooks, PDA etc. It allows the user the flexibility to move and not be confined to the conventional desktop computer.

A wireless network is any type of computer network that uses wireless data connections for connecting network nodes .Wireless networking is a method by which homes, telecommunications networks and enterprise (business).Installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model  network structure.

In this modern era, wireless communication has become a requisite need like water and electricity which is part of our personal as well as our professional life. When we talk about wireless communication, the first word which comes to our mind is Wi-Fi. It uses 2.4-5 GHz RF (radio frequency) to deliver internet access around a wide area. As more and more users are connected to the network, the rate of data transfer gets reduced. So when more people access wireless internet, airwaves gets clogged and it makes difficult to latch onto a reliable signal. Transmission of data is done using radio waves which is just one part of spectrum. We are totally dependent upon this very prevalent service. But it has also many

In last few years cellular communication is developed, mobile users are increased and also introduce new features of smart technologies such as virtual environment of data transfer using D2D communications. It performs high speed communication for local cellular networks in approaches [1]-[4] and to minimizing the BS power consumptions as in [5]. The D2D communications proposed for different time slot and same frequency used and carefully managed interference, reducing Base station traffic and minimizing transmission power. The different power saving mechanism in Radio Resource Management (RRM), power control is very important for cellular networks and beneficial to link in adaptation, interference reduction. Depending off on time of day or geographic location BS may be an idle but mobile terminal not negatively affected.

In a remarkably short period of time, Cell phones and mobile technology have become omnipresent in the day-to-day life in Bangladesh. People around the country are using their cell phones for a variety of purposes, especially for calling, texting and taking pictures as well as social awareness raising, literacy training and skill development. The rapid expansion of mobile phone network has been accompanied by a growing emphasis on providing more cellular based services and promoting efficiency and financial sustainability. The recent addition to the list is the mobile banking service.

telecommunication has perhaps been to bring us humans closer to one another. In doing so, one of the greatest contributors has been cellular phone technology. Thus, we tried to contribute, to our limitations, to the development of the cellular network. Cellular technology not only connects people, it is also playing a colossal role in boosting the economy of Bangladesh. With the increasing popularity of cellular phones and arrival of giant phone companies, cellular traffic continued to

A cellular network is a radio network distributed over land areas called “cells”. Each cell is served by one fixed-location transceiver, which is called a “base station”. When cells are joined together, they provide wireless coverage over a large geographic area, within which mobile stations or phones can communicate with base stations and each other. Overlapping coverage areas allows transmission to be maintained even when mobile stations are moving between cells. Assigning a different set of frequencies to neighboring cells avoids wireless signal interference.

4G wireless mobile communication networks are been specified to support display, battery and computational power etc. 4G wireless mobile communication networks should not focus on air interface and data rate, but instead cover advance wireless mobile communication networks and high speed wireless access system into different platforms. Based on different model, 4G wireless

Mobile operating systems are used to run applications and programs on smartphones, tablet PCs. It is also used to manage cellular and wireless network connectivity, phone access.

The wireless technology recorded the magnificent growth since its foundation as the result there has been an surprise growth in the number of users using wireless all over the world during the last decade. As the number of user increases, the system operators regularly deploy smaller cells to increase the system capacity. As the cell size reduces, the crossing of cell boundary increases which results, a higher handoff rate. 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

WiMAX technology has been approved by Bangladesh Government in last quater of 2008 in Bangladesh. Use of this technology has been increased through the passage of time. WiMAX combines the performance of Wi-Fi with the range and quality of service (QOS) of a carrier-grade cellular technology. WiMAX networks can be as small as single base stations with a few subscriber units, to much larger networks with thousands of users. 4G WiMAX gives us incredibly fast wireless access to the internet from four to ten times faster than 3G wireless. WiMAX technology will allow the subscribers to enjoy the amazing experience of high speed internet along with data, voice and video.There are few WiMAX service provider in Bangladesh, among
