...4G Wireless Network | Compare and Contrast 3G Wireless Networks to 4G Networks 3G networks allow people to have high speed access to data and voice services, they are essentially a high-speed mobile Internet, that can offer speeds of up to 3.1 megabits per second (Mbps) or more. This speed is around the same speeds offered by earlier sellers of cable modems. However, depending on where you are and how many users there are, the actual speed of 3G networks will fluctuate. Even though 3G is still more commonly used, the recently introduced 4G networks have quickly become the standard for wireless communication. The 4G networks are 4-10 times faster than 3G protocols and are ideal for watching streaming videos or movies, and offer more security, unlike a Wi-Fi connection. We can compare and contrast 3G wireless networks and 4G networks in four areas: service and application, network architecture, data throughput and user perceptions. The following standards are typically branded 3G: CDMA2000, UMTS, and EDGE. Whereas 4G wireless is the term used to describe the fourth-generation of wireless service such as WiMax and LTE. Although 4G is a step up from 3G, the limited coverage that is the present 4G market keeps 3G as the frontrunner in wireless protocols being used by the public. While all 4G service is called "4G," the underlying technology is different. Sprint, for example, uses WiMax technology for its 4G network, while Verizon Wireless uses a technology called Long Term...
