Fiber-Wireless testbed using software defined radio for protocol and algorithm testing
Fiber-Wireless (FiWi) network can provide abundant bandwidth capacity and mobility to the end-users. It also eliminates the need of having complete tedious end-to-end fiber installation from the central office to the users, which saves tremendous capital expenditure. However, FiWi is still progressi...

Almost all recently proposed testbed designed for FiWi are using hardware that lacks in programmability feature, making it challenging to implement any protocols and algorithms.
