Mobile Communication : An Overview Of 4g And Its Features, Architecture, Key Technologies And Challenges

The telecommunication industry that AT&T essentially created has undergone radical advancements, particularly within the last decade. According to the IBM Institute for Business Value, approximately 15% of the world’s population had access to a telephone in 1999 but by 2009, 70% of the world’s population had mobile phone subscriptions (Nelson & van den Dam, 2010). Given the extraordinary explosion of mobile computing and wireless communications, continued advancements within the global telecommunication industry are certain. A number of trends drive this evolution including the advancement of devices and network access technology, changes

The use of cellular phone has skyrocketed since low-price phones and services plans became widely available to the general public in the recent years. As cellular phone is getting more and more

Since the introduction of the first mobile phone by Motorola in 1973, the phone industry has had a major boom and has increased in demand by the minute since then. Mobile phones have become so popular that now every year, each producer is competing on who can release the “newest” model and basically who can “reinvent the wheel” all over again with “new and improved” specs these mobile

Cellular Broadband is used to access Internet on mobile devices, such as mobile phones, tablets and mobile dongles. There are currently three different technologies used to access the Internet from a mobile device, these include 2G, 3G and the current 4G. Cellular broadband is a subscription-based service, which usually comes as part of your mobile tariff from your provider. However, you can get separate tariffs just for cellular broadband, these are used in laptops and tablets to provide Internet access on the move. ITU Telecom World research indicates that 90% of the world is covered by a 2G signal; where as 45% of the world has a 3G signal (www.itu.int). This shows that there is a high demand for this service, and it is a very popular option to access Internet while bring mobile. This type of service is something that could be incorporated within our health authority network, for example a 4G connection can be used as a backup internet backbone as well as employees using the service to access

Mobile data communication has become a very important and rapidly evolving technology as it allows users to transmit data from remote locations to other remote or fixed locations. This proves to be the solution to the biggest problem of business people on the move mobility. In this paper it will define mobile computing, name and tell what you can do with mobile computers, discuss the advantages and disadvantages of mobile computers, name several major trend in mobile computers and finally, we look at the future of Mobile computing in the real world.

There are 6 challenges of 5G mobile networks; higher capacity, higher data rate, lower E2E latency, massive device connectivity,

The first generation of mobile communications started with the Advanced Mobile Phone Systems (AMPS), which was an analogue system regarded as 1G. Then came GSM and CDMA-one (pretty much regarded as 2G) and then to UMTS and EV-DO, which are 3G technologies. The latest technologies for 4G are LTE (from the 3GPP group) and 802.16m (from the IEEE). In the case of 802.16m, the candidate for 4G is also known as Wireless MAN Advanced, or WiMAX2. LTE progresses through versions known as releases. The latest release that qualifies as being 4G is

4G or fourth generation technology is a mobile communication standard intended to replace 3G allowing wireless internet access at much higher speeds!

The bandwidth and location information available to 3G devices gives rise to applications not previously available to mobile phone users. Hence, there are some applications in 3g

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 complete the term paper .

Mobile wireless access networks have evolved from first generation, second generation, third generation, fourth generation and now fifth generation (Umar, 2004). Umar further states that first generation cellular systems used analogue transmission and were

Rise in mobile communications has escalated in the last decade and smartphones and other phones endowed with

The core technology of 4G is orthogonal frequency-division multiplexing (OFDM) which belongs to Multi-Carrier Modulation (MCM). It divides assigned channel into orthogonal sub channels, modulating and transmitting on each sub channel of narrowband (Aceña 2005). 3.2 Telecommunication system structure 3G is based on cellular network (shown in Figure 1), the core network of 3G is developed from GSM-MAP, AMPS and ANSI-41 which is the core network of GSM, the air interface and the corresponding system is backward 2G compatibility (Luo et al. 2003).

As the use of 2G phones became more widespread internet usage was growing. If we can expect 3- 5 mbps of speed, which is actually equal to cable/DSL kind of speed in to a moving device! That’s what all about 3G. This enabled faster data-transmission speeds, greater network capacity and more advanced network services, basically turns your cell phones to a mini computer.Also 3G is that Wide Band Voice Channel, by this the world has been contracted to a little village because a person can contact with other person located in any part of the world and can even send messages too. 3G gives clarity of voice as well can talk without any disturbance simultaneously. Not only these but also have entertainments such as Fast Communication, Internet, Mobile T.V, Video Conferencing,

In Europe, mass market commercial 3G services were introduced starting in March 2003 by 3 (Part of Hutchison Whampoa) in the UK and Italy. The European Union Council suggested that the 3G operators should cover 80% of the European national populations by the end of 2005.
