Abstract
The performance of radio over fiber (RoF) links using low cost
optoelectronic components is assessed for distributed antenna applications
in next generation wireless systems. Important design issues are discussed
and an example link design is presented for a wireless system requiring the
transmission of four radio channels per link direction, each with 100 MHz
bandwidth, modulation complexity of 256-QAM and 2048 OFDM subcarriers. We
show that the noise introduced by the RoF links does not have a significant
impact on wireless range, provided the wireless system has uplink power
control. Finally, we compare the cost and performance of RoF links for this
application with alternative link types that use digitized radio
transmission and show that RoF is the optimum choice from a cost
perspective.
