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.
