Problem Statement

The demand for broadband services has driven

Research on milli meter wave frequency band communications for wireless access networks.

Solutions to overcome the problems by using low-attenuation, electromagnetic interference-free optical fiber i.e. Radio over Fiber (RoF)

Cost-effective, practical and relatively flexible system.
