Abstract

From industries to individuals everyone requires the concept of connectivity everywhere. Technology is evolving very fast than ever before. Beginning with analog communication then transfer to digital communication techniques took place. Early years of this decade has seen a revolution in mobile systems like 2G. Internet related service required higher bandwidth and quality of service. This led to the evolution of 3G system through Universal Mobile Telecommunication Systems (UMTS). Now 3G services are popular across the globe and have a strong customer base. Increase in further demands requires a raise in standard which has led to the advent of Long Term Evolution Standards of wireless communication technologies. This paper evaluates 3G and 4G Networks in terms of their service, network architecture and performance. It also deals with different technologies of these wireless standards like 4G LTE, WiMax, 4G WiBro in terms of their upstream and downstream speeds, availability of service, perception of users and their compatibility factors. Outlook of fierce competition among the service providers for 4G LTE and in what way it would benefit subscribers will also be discussed. Finally this paper will study the trend by which Verizon had the ability to cover more markets than AT&T for 4G LTE.

Keywords: upload speed, download speed, compatibility, service availability, architecture, user perception.

Compare and Contrast 3G and 4G Wireless Networks

Comparing and contrasting 3G and 4G wireless networks can be based on important factors like services and applications, network architecture, data throughput and user perceptions. Inherent capabilities of 3G networks are delivered through CDMA2000, UMTS, and EDGE. They offer position based services like GPS, B2C Services, entertainment, better mobility and interactive services. It includes variety of applications...
