Next generation wireless cellular 5G networks operating in mmWave band target a peak rate of 10Gb/s for both outdoor and indoor applications. However, in this frequency band penetration through brick pillars, concrete walls, and tinted glass hits a barrier of 30dB or more attenuation. An outdoor RF/relay station has to be placed along with an indoor RF/relay station and a mechanism to connect the...
Record wireless data transmission of 31.4 Gbps within 7 GHz license-free band at 60 GHz is experimentally demonstrated using adaptive bit-loading OFDM modulation. Adaptive bit-loading OFDM also enables extended fiber transmission distances beyond 5km.
This paper demonstrates the feasibility of a simple multigigabit-per-second (Gbps) radio-over-fiber (RoF) system employing multilevel orthogonal frequency-division-multiplexing (OFDM) signal modulation at 60 GHz and a single-electrode Mach-Zehnder modulator (MZM). In this paper, the impact of fiber chromatic dispersion and OFDM beat noise on the performance of the RoF system are investigated by theoretical...
We demonstrated near-ballistic uni-traveling-carrier photodiode based broadband photonic transmitter-mixers with quasi-Yagi radiators fed horn antennas. 100 GHz wireless transmission with date rate as high as 12.5-Gb/s via bias modulation under high photocurrent (20 mA) has been achieved.
