Conclusion

Ultra fast up- and down-loading over wireless Gigabit

Ethernet has been proposed and demonstrated as an

application of 60GHz-band WPAN.

1.25Gbps full duplex 1000Base-T wireless Gigabit

Ethernet has been developed adopting 60GHz-band

ASK transceivers with 2Gbps operation ability.

Alignment free set up and wide transmission area of

millimeter-wave wireless link have been realized

using wide beam antennas.
