Asymmetric wireless communication system using two different radio technologies
View Patent ↗A wireless communication system and method are provided, where a base station communication device includes a carrier wave-based transmitter and an ultrawideband receiver. A mobile communication device includes a carrier wave-based receiver and an ultrawideband transmitter. Carrier wave communications are carried out in a forward channel from the base station communication device to the mobile communication device, and ultrawideband communications are carried out in a reverse channel from the mobile communication device to the base station communication device. As a result, the power requirements of the mobile communication device are significantly reduced.
1. A wireless communication system, comprising:
a base station communication device including a carrier wave-based transmitter and further including an ultrawideband receiver; and
a mobile communication device including a carrier wave-based receiver and further including an ultrawideband transmitter;
wherein carrier wave communications are carried out in a forward channel from said base station communication device to said mobile communication device, and ultrawide band communications are carried out in a reverse channel from said mobile communication device to said base station communication device.
2. The wireless communication system of claim 1 , wherein said wireless communication system comprises a radio system.
3. The wireless communication system of claim 1 , wherein said wireless communication system comprises a cellular telephone system.
4. The wireless communication system of claim 1 , wherein said wireless communication system comprises a satellite telephone system.
5. The wireless communication system of claim 1 , wherein said wireless communication system comprises a pager system.
6. The wireless communication system of claim 1 , wherein said base station communication device is connected to a land line.
7. A wireless communication system, comprising:
a base station communication device including a carrier wave-based transmitter capable of transmitting a carrier wave-based signal and further including an ultrawideband receiver capable of receiving an ultrawideband signal; and
a mobile communication device including a carrier wave-based receiver capable of receiving said carrier wave-based signal and further including an ultrawideband transmitter capable of transmitting said ultrawideband signal.
8. The wireless communication system of claim 7 , wherein said wireless communication system comprises a radio system.
9. The wireless communication system of claim 7 , wherein said wireless communication system comprises a cellular telephone system.
10. The wireless communication system of claim 7 , wherein said wireless communication system comprises a satellite telephone system.
11. The wireless communication system of claim 7 , wherein said wireless communication system comprises a pager system.
12. The wireless communication system of claim 7 , wherein said base station communication device is connected to a land line.
13. A method of wireless communication, comprising the steps of:
carrying out communication from a base station communication device to a mobile communication device using a carrier wave-based transmission signal; and
carrying out communication from said mobile communication device to said base station communication device using an ultrawideband transmission pulse train.
