18.4.1 Wireless-Over-Fiber Systems
The principal attraction of wireless-over-fiber technology is that it centralizes most
of the transceiver functionality by transmitting the wireless signals in their modu-
lated format over fiber, and reduces the fielded access points to antennas with
associated amplifiers and frequency converters. Standards-independent and
multiservice operation is facilitated.
At frequencies used for existing cellular systems (900 MHz and 1.8 GHz for
Groupe speciale mobile (GSM), 2 –2.3 GHz for Universal mobile telecommunication
system (UMTS)), semiconductor lasers, directly modulated with the data-m ...
