Introduction

The Internet has revolutionized the way people live their personal and professional life. Not only it is contributing to enhance their professional productivity, it is actively being used as a social medium of communication as well. The access to new technologies, such as Web 2.0, requires the user to possess a broadband connection in order to enjoy its full benefits. Another concept that has gained popularity in recent years is the ability to be mobile, whether for short or long distances. To cater these demands, mobile communication standards have evolved steadily as well. Currently, a number of standards are competing in the markets worldwide to provide broadband communication service while giving the user freedom to move from one place to another.Two of these standards have gained a lot of popularity and more and more operators are seeking to deploy them. These standards are HSPA and WiMAX. Though both standards are designed to deliver high-speed wireless broadband connectivity, they use different technology to serve this purpose.

The focus of this paper is to compare the differences in HSPA and WiMAX standards. It provides information about the difference in the architecture as well as in key technologies on which these standards are based (Ericsson, 2009).

Introduction of WiMAX

Wireless Microwave Access or WiMAX is a standard designed for delivery of broadband data connectivity without the use of wireless. It has been described by IEEE and has been designated 802.16 Wireless Metropolitan Area Network standards by them. WiMAX standard has been designed to provide a wireless alternative to a conventional broadband standard such as DSL and Cable. The significant problem with these services is that they require dedication of a lot of resources in term of time, money and personnel for the deployment of their access network. WiMAX, however, provides a much quicker way for the domestic and commercial customer to gain access to high-speed data connectivity, primarily because it is a wireless standard and does not require much effort for its access network deployment. Being a cheaper alternative, WiMAX is becoming the technology of technology for data connectivity provider in third world countries and has met significant success in gaining a large market in these countries (Radha Krishna Rao, & Radhamani, 2007).

Currently, there are two standards of WiMAX that have seen deployment in various countries around the world. The 802.11d standard is primarily used for providing high-speed data connectivity over stationary links with support for non-Line-of-Sight transmissions. It is also often seen as a prime candidate for establishing backhaul links. The 802.16e standard supersedes the 802.16d standard with major modifications to it including support for mobility. The 802.16e standard also increases the maximum transmission rate to up to 75 megabits per second (Ronai, 2008).
