International Journal of Engineering Trends and Technology
In this paper, the authors evaluate the advantages of both microwave and infrared technology and examine some crucial issues where each technology provides added value. Both microwave and infrared transmission systems are use for short distance network connections. They need line-of-sight and have its merits and demerits. The evaluation of the two transmission systems were in the areas of frequency spectrum, bandwidth, technical issues, confidentiality, security issues, distance coverage etc. From the paper, it was found that when frequency spectrum licensing is difficult and expensive to obtain, infrared transmission systems have a good advantage, and infrared transmission system is less inclined to be intercepted.
