Integrated service quality enhancement of wireless optical communication systems for long haul transmission distances

Abstract

Optical wireless communication network is gaining acceptance in an increasing number of sectors of science and industry, owing to its unique combination of features: Extremely high bandwidth, rapid deployment time, license and tariff-free bandwidth allocation, and low power consumption, weight, and size. The demand of high signal bandwidth in optical wireless communication networks is growing exponentially day by day, as the numbers of users have been increased drastically over the span of last five years. The next generation wireless communication systems therefore need to be of higher standards, so as to support various broadband wireless services such as, video conferencing, videophones, high-speed internet access, etc. The existing wireless systems can hardly provide transmission capacity of the order of few Mbps. However, wireless optical fiber technology has the potential of providing data capacity of the order of Mbit/sec and Tbit/sec, respectively. Therefore the requirements of optical broadband wireless system can be met through the integration of optical communication fiber and millimeter wave optical wireless systems. Terrestrial optical wireless communication network is emerging as a promising technology, which makes connectivity possible between high rise buildings and metropolitan and intercity communication infrastructures. We have developed a light beam carrying the audio and video information, which facilitates extremely ultra high transmission data rates for ultra long transmission distances within Shannon propagation technique.
