11th May 2010Executive summaryIn this century, the demands for internet transforms from the usual browsing the net to the use of hastily download and wireless (Communications, 2008). By use of the new arising techniques, 3G’s less speed and minimal volume of download is not able to meet the needs of an individual, hence arise of 4G mobile system that enhances greater speed, minimum expenses, fixed quality and focuses on open wireless platform. Architecture whose duty is to display the usefulness for upgrading the day to day running of business, 4G up to today is being checked if its present speed can be adjusted to 320Mb or if it’s impossible.
The 4G technology is one of the systems being seen to be in act in some years to come. Some of the 4G application will be elaborated more. INTRODUCTIONIn this present world mobility has become an essential factor for most people and this is true even in future (Comin, 2004). Mostly a number of individuals are not willing to use an infrastructure that is based with networking, for example mobile phones in use, laptop computers or personal digital assistant to communicate arising matters in a gathering, receiving or giving back email online and that’s the main reason why wireless networks are required in such cases (Communications, 2008).
With use of wireless network it’s easier for everyone to be connected with others from different parts of regions at any given time; however 4G plays a vital duty in reaching out mobiles in the future networks. The task for various personnel is to be equipped with more knowledge about 4G (Sherman & Sword, 2009). This knowledge is set to provide an important introduction of 4G’s features and working modes.
It’s well known that a SWOT analysis elaborates in deeper details the use of 4G in companies and organizations to upgrade their business (Ghadialy, 2006). 2) Definition of 4GA) Summary introduction of 1G-4G wireless systemsThe wireless mode of passing information systems are mostly grouped by generation and the main tasks of every generation is as follows; 1G (first generation wireless system which was implemented in 1984) is the voice only analog cellular system. Parts of the bands were divided into some pathways of passing information, of which each of the above could be made active by the subject using them (Ghadialy, 2006). 2G (Second generation wireless system implemented in 1991) it was directed into digital passage technology to be in line with the capacity needs of modern sound services.
The amount of data found to be held by the basic 2G networks were presented to be 9.6 kbps. This system developed multi functions compared to 1G a good example said to be caller identity and the most common short message service in short called sms (Gary, 2009). 2.5G (2.5 generation wireless system implemented in 1999) in this type of system all the clients were given permission to appreciate the data counts with a software increase at the base transceivers stations (BTS).
This 2.5G was so much in need for extra data performance and access to the internet, subsequently the 2.5G system has accepted data speed of 64-144 kbps that facilitates web browsing in various phones, voice mail messages, exchanging email messages and using fax (RFiD Centre, 2010).
