    4G Wireless Networks compare and contrast 3G TO 4G wireless networks in terms of services and applications, network architecture, data throughput, user perceptions. Must distiguinsh between 4G LTE, 4G WiMax, and 4G WiBRO networks based on upload and download speeds, user preceptions, backward compatibility, and service availability. Must Identiy why the competition between 4G LTE carriers has been so fierce and satisfactorily described the benefits of this competion to the subscribers. 4G Wireless Networks Introduction In the timeline of mobile phone technology, 3G technology will always be tied to the introduction of the smart - phone ; but as our mobile phones evolve so does our technology. Our society is a demanding one and for the technologically savvy those demands are in the form of mobility, connectivity and faster mobile technology. Compare and C ontrast 3G W ireless N etworks to 4G N etworks We can compare and contrast 3G wireless networks and 4G networks in four areas: service and application, network architecture, data throughput and user perceptions. S ome examples of s ervices offered by 3G wireless networks are CDMA2000, UMTS, and EDGE along with a list of others while 4G networks offer Wimax2 and LTE - Advance. The applications are where a lot of users get hooked on technology. 3G opened a whole new realm of possibilities with applications allowing users to stream video and audio, video calling, video conferencing and a huge array of multimedia applications in the mobile environment. 4G applications include

    Assignment 2: 4G Wireless Networks 2 gaming services, amended mobile web access, high definition mobile television, video conferencing, IP telephony and even 3D television. One of the differences between these two standards of networks lies in the network architecture; the 3G mobile network is a W ide A re a C ell B ased network with a circuit - switched subsystem. It relies on large satellite connections that connect to telecommunication towers. For example, users make a call or open the internet; a radio signal is transmitted to a 3G tower antenna or cell site. That data travels from the cell site to a central switching office by a wire - line fiber - optic network. Then the central switching office connects the call or data request with the rest of the world. The 4G networks are an integration of wireless LAN and Wide Area. 4G does not have a circuit - switched subsystem, it is a purely packet based Internet Protocol (IP) system. When a Sprint user accesses a website or uses an internet based application, a radio signal is sent to a 4G cell site. That data request travels from the satellite to a central office wirelessly using microwave technology. This is a more reliable method than a wire - line transmission because there is less network downtime. The central office, in turn, connects the data using a wire - line network to the outside world. Another difference is in the data throughput. The data throughput rate for 3G is up to 3.1 mbps with a bandwidth of 5 – 20MHz; while the data throughput rate for 4G networks is 3 to 5 mbps but potentially estimated at a range of 100 to 300 mbps with a bandwidth of 100MHz (or more). Many users are happy with their 3G wireless network service. It is readily available and competitive pricing have enabled millions of users to access mobile technology in ways they never imagined possible. However, 4G ne tworks have had outages and complaints about coverage areas. The differences are definitely there between the two technologies but the users of today have only gotten a brief taste of the potential benefits of 4G service. The common users
