1. Compare and contrast 3G wireless networks to 4G networks in terms of services and application, network architecture, data throughput and user perceptions. With the world’s need for faster and efficient technology, 3G and 4G networks gives subscribers a wide range of advanced services while achieving greater network capacity through increased bandwith, transfer rates and spectral efficiency. In the simplest terms 3G and 4G are the third and fourth generation data networks. 3G opened a whole new realm of possibilities with applications that allows users to stream video and audio, video calling, video conferencing and a huge array of multimedia applications in the mobile environment. The 4G applications not only provide the same as the 3G but also included gaming services, mobile web access, high definition mobile television, IP telephony and even 3D television (Segan 2010). One of the differences between these two standards of networks lies in the network architecture. The 3G mobile network relies on the large satellite connections that connect to telecommunication towers. An example of this is that data travels from a telecommunication tower by a wire-line fiber optic network. The 4G networks are integrated within the wireless LAN and WAN. It doesn’t operate on a circuit switched subsystem but based on the Internet Protocol system (Segan 2010). Another difference is in the data throughput. The data throughput rate for 3G is up to 3.1mbps with a bandwidth of 5-20 MHz, while the data throughput rate for 4G is 3-5 mbps with a potential estimated range of 100-300 mbps with a bandwidth of 100 MHz. Many users are happy with their 3G wireless network service because it is readily available and competitive pricing (Viswanahan 2012). However, the 4G networks have had outages and complaints about the coverage areas. But as 4G improves their technology there will...
