Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
117 words
An impulse radio mobile communications system, comprising: a first impulse radio transmitter means interfaced with a voice or data communication network; a first impulse radio receiver receiving voice or data information from said first impulse radio transmitter means. a second impulse radio transmitter in communication with a second impulse radio receiver; said second impulse radio receiver in communication with said first impulse radio transmitter; and at least one non-impulse radio wireless communication means interfaced with said second impulse radio transmitter and said first impulse radio receiver by an interface, said interface provides for the switching between said at least one non-impulse radio wireless communication means and said second impulse radio transmitter and said first impulse radio receiver.
Claim 2
Dependent Claim
117 words
An impulse radio mobile communications system, comprising: a first impulse radio transmitter means interfaced with a voice or data communication network; a first impulse radio receiver receiving voice or data information from said first impulse radio transmitter means. a second impulse radio transmitter in communication with a second impulse radio receiver; said second impulse radio receiver in communication with said first impulse radio transmitter; and at least one non-impulse radio wireless communication means interfaced with said second impulse radio transmitter and said first impulse radio receiver by an interface, said interface provides for the switching between said at least one non-impulse radio wireless communication means and said second impulse radio transmitter and said first impulse radio receiver.
Claim 3
Dependent Claim
58 words
The impulse radio mobile communication system of claim 1 , wherein said switching between said at least one non-impulse radio wireless communication means and said second impulse radio transmitter and said first impulse radio receiver occurs automatically based on the signal strength of said non-impulse radio wireless communication means and the signal strength of said impulse radio communications.
Claim 4
Dependent Claim
41 words
The impulse radio mobile communication system of claim 1 , wherein said switching between said at least one non-impulse radio wireless communication means and said second impulse radio transmitter and said first impulse radio receiver is manually selected by a user.
Claim 5
Dependent Claim
51 words
The impulse radio mobile communication system of claim 3 , wherein said first impulse radio transmitter and said second impulse radio receiver are contained in a base station networked within a plurality of impulse radio base stations, said plurality of impulse radio base stations providing communication coverage for a given area.
Claim 6
Dependent Claim
37 words
The impulse radio mobile communication system of claim 3 , further comprising a signal strength detection means, said signal strength detection means detecting the strength of cellular/PCS wireless communication signals as well as impulse radio communication signals.
Claim 7
Dependent Claim
83 words
The impulse radio mobile communication system of claim 3 , further comprising a microprocessor for controlling communication functions, said microprocessor controlling audio circuitry associated with said second impulse radio transmitter and said first impulse radio receiver and audio circuitry associated with a Cellular/PCS transmitter and a CellularPCS receiver, wherein when said signal detection means detects a weak signal in an impulse radio transmission, the microprocessor directs said audio circuitry of said cellular PCS transceiver to be activated by way of an audio switch.
Claim 8
Dependent Claim
78 words
The impulse radio mobile communication system of claim 3 , further comprising a microprocessor for controlling communication functions, said microprocessor controlling audio circuitry associated with said second impulse radio transmitter and said first impulse radio receiver and audio circuitry associated with a Cellular/PCS transmitter and a CellularPCS receiver, wherein when said signal detection means detects a signal of sufficient strength to communicate via an impulse radio communication means, ongoing Cellular/PCS communications are automatically switched to impulse radio communications.
Claim 9
Dependent Claim
22 words
The impulse radio mobile communication system of claim 1 , wherein said voice or data communication network is a land line network.
Claim 10
Dependent Claim
22 words
The impulse radio mobile communication system of claim 1 , wherein said voice or data communications network is a cellular wireless network.
Claim 11
Dependent Claim
22 words
The impulse radio mobile communication system of claim 1 , wherein said voice or data communication system is a PCS wireless network.
Claim 12
Dependent Claim
29 words
The impulse radio mobile communication system of claim 1 , wherein said first impulse radio receiver is contained in a plug in accessory to a cellular or PCS telephone.
Claim 13
Dependent Claim
29 words
The impulse radio mobile communication system of claim 1 , wherein said impulse radio transceiver is operably integrated into a handset capable of cellular, PCS or impulse radio communications.
Claim 14
Dependent Claim
62 words
The impulse radio mobile communication system of claim 1 , wherein said switching between said at least one non-impulse radio wireless communication means and said second impulse radio transmitter and said first impulse radio receiver occurs automatically based on a predetermined distance from said first impulse radio transmitter to said second impulse radio transmitter as determined utilizing impulse radio distance determination techniques.
