An assessment of emerging wireless broadband technologies

Abstract

This thesis provides an objective assessment in emerging wireless broadband technologies that are proposed as a solution to the "last mile" problem. Local Multipoint Systems (LMDS), Free Space Optics (FSO) and High Altitude Long Endurance (HALE) systems are examined by comparing alternative technological options and solutions. Additionally, these systems are compared with the wired competitor technologies. The main benefits of wireless versus wired technologies are ease and fast deployment, lower deployment cost, demand-based buildout and better performance in terms of bandwidth. Although xDSL and cable networks are the dominant technologies in providing broadband services today, emerging wireless broadband technologies are expected to significantly increase their market share over the next years. Deploying a wireless network is a difficult task requiring more than an understanding of the technological concepts. This thesis provides guidelines for the deployment of both LMDS and FSO systems by dividing the areas of interest into three categories: identifying the target market, developing the business case and deploying the network. The factors that affect each category are explained, and finally a deployment strategy is provided.
