Abstract
This work describes a concept of a hierarchical radio-over-fiber (RoF)
network architecture that provides both intra- and inter- network connectivity
for end user wireline and wireless terminals with high-bandwidth, in-building
access applications. An intelligent gateway router (IGR) is proposed as a
unified platform to accommodate multi-gigabit, millimeter-wave services at
60-GHz band as well as being backward compatible with all current wireless
access technologies such as WiFi and WiMAX. In addition, we further present
an advanced multi-band optical carrier generation technique that can simultaneously
deliver independent 60-GHz mm-wave, 2.4-GHz WiFi, and 5.8-GHz WiMAX signals
efficiently carried over the same wavelength, and is suitable for the proposed
IGR. Finally, we report, for the first time to our knowledge, a campus-wide
field trial demonstration of RoF system transmitting uncompressed 270-Mbps
standard definition (SD) and 1.485-Gbps high definition (HD) real-time video
contents carried by 2.4-GHz radio and 60-GHz millimeter wave signals, respectively,
between two on-campus research buildings distanced over 2.5-km standard single
mode fiber (SMF-28) through the Georgia Institute of Technology's (GT) fiber
network.
