“…Millimeter-wave bands at around 60 GHz and higher could provide bandwidth enough to easily support multi-gigabit capacities. The 60-GHz band has been widely studied as it provides about 7-GHz bandwidth for unlicensed communications [1,2]. Bands of around 100 GHz and higher show larger potential bandwidths available to support very high capacities envisioned (towards 100 Gb/s) [3].…”

Simple 60-GHz MB-OFDM Ultrawideband RoF System Based on Remote Heterodyning

“…UWB, a mature technology with efficient software and single-chip solutions available, exhibits advantages including high data rate, low power consumption and low cost. The 60-GHz millimeter-wave (mm-wave) frequency band, where several gigahertz of license-free bandwidth are available, has recently been considered for the radio-over-fiber (RoF) delivery of multi-Gb/s UWB signals to end-users for bandwidth-intensive applications including high-definition television (HDTV), video-ondemand, wireless high-speed file transfer and wireless audio transmission [2].…”

Combined single-mode/multimode fiber link supporting simplified in-building 60-GHz gigabit wireless access

“…Millimeter-wave wireless systems at around 60 GHz and higher frequencies can provide bandwidth enough to easily support multi-Gb/s communications, being a potential solution for future seamless integrated optical/wireless access, as well as for mobile backhauling [2]. The 60-GHz band has been widely studied as a wide bandwidth has been regulated in many countries for unlicensed use with a high equivalent isotropic radiated power (EIRP) of higher than 40 dBm allowed [3]. A number of standards in the 60-GHz band have recently been proposed, including WirelessHD, ECMA-387, IEEE 802.15.3c, and WiGig.…”

“…The proposed system has the following advantages: 1) Electrical OFDM modulation with a high number of subcarriers has been widely used in optical and wireless communications systems to benefit from its high spectral efficiency, flexibility, and robustness against fiber dispersion impairments and wireless multipath fading [3], [21]. 2) Seamless allocation of multiple channels in the wide RF bandwidth is demonstrated enabled by optical comb generation [22].…”
