Hybrid free space optical/microwave communication networks: A unique solution for ultra high-speed local loop connectivity

摘要

Recently, free space optical communication systems have been discussed as solutions to provide high-speed local loop connectivity in metropolitan area network environments. Free space optical technology is capable of providing much higher bandwidth than any other competing wireless connectivity options such ascalssical RF or microwave systems. A widespread concern regarding free-space optical systems is related to its capability to provide the igh availability figures commonly envisioned by network service providers. Wireless microwave systems tend to have high availability figures, but at the expense of the ability to operate at higher data rates. LightPointe suggests an integrated networkk solution that combines the benefits of both technologies.
