A compact-range wireless access system in the 60 GHz-band has been proposed for multi-Gb/s data transfer. Large array antennas adopting in the transmitter operate in their near-field regions, and provide us with a large communication zone and a pure propagation environment. However, intersymbol interference (ISI) may significantly degrade the system performance especially when the receiver is close...
A compact range wireless access system in the 60 GHz-band has been proposed for multi-Gb/s data transfer. A prototype GATE (Gigabit Access Transponder Equipment) was made to evaluate the coverage as well as the system performance of received power, bit-error rate (BER) and signal-to-noise ratio. Originally, the double-layer corporate-feed waveguide slot arrays with different number of elements were...
A compact range wireless access system in the 60 GHz-band has been proposed for multi-Gb/s data transfer. A prototype Gigabit Access Transponder Equipment was made to evaluate the system performance of bit-error rate and signal-to-noise ratio. An error-free communication zone up to 11 m is available by adopting the 32×32 and 64×64-element waveguide slot arrays in the transmitter. However, the BER...
A novel compact-range wireless access system is proposed for multi-Gb/s data transfer in the 60-GHz band. Large-array antennas in the access point generate a quasi-plane wave and form a stable communication zone proportional to the antenna size. The link budget based upon the Friis transmission equation is not applicable as ever in this compact-range communication system. The signal coverage up to...
