Abstract

Laser and LED-based wireless communication systems provide license-free interconnection for voice, data. And video transport with high bandwidth and high data rate capabilities. These systems allow for the immediate, reliable and low-cost extension of copper and fiber-based networks to any end user, providing efficient bypass access to high data rate backbone networks and interconnection among voice and data network components operating at speeds ranging from T-1 voice to full throughput ATM at 155 Mbps. The wireless optical beams constitute a 'Virtual Fiber^TM' in the air, providing the capabilities of fiber in situations where wired connectivity is unavailable, impractical, expensive or slow-to-implement, while achieving a combination of cost, bandwidth, speed and reliability that cannot be matched by microwave, spread spectrum or other competing wireless technologies. The use of optical beams in the air eliminates the rf bottleneck by providing bypass access and building-to-building links with transport connectivity at and above 155 Mbps. Future generations are already under development which will accommodate emerging technologies including gigabit ethernet. This paper addresses the following issues: (1) Trade-offs between rf and optical wireless technologies and products. (2) The effects of weather and the achievement of all-weather operations to distances of 1 km. (3) The achievement of reliable operations with examples and case studies.
