Abstract
The growth of broadband Internet access has paved

the way for the development of many newer existing

technologies. As the costs of implementing

broadband access soar, the best alternative will

be to use wireless technologies. At a carrier

frequency of about 28 GHz, the potential benefits

of Local Multipoint Distribution Service (LMDS)

will eventually outweigh those of its current

competitors in the wired market. Since the rural

communities will reap the most benefits from this

technology due to its low costs, studies on the

channel behavior and terrain relationships must

be done.

This thesis aims to provide a preliminary study on

the effects of propagating an LMDS signal over a

lake surface. Currently, there is not enough

information to prove the feasibility of deploying

an LMDS system for this terrain. Some background

on the technology and rough surface theory is

provided for the reader to better understand the

environment that is being investigated. Simulation

results are presented as a guide to assist future

researchers to conduct a field measurement

campaign. A block diagram of a potential

measurement system is also provided to aid in the

development of the tools necessary for the

measurement of an actual channel.
