Abstract

An apparatus for providing additional processing power to a portable, wireless, communication device. The apparatus includes a housing detachably connectable to the portable, wireless, communication device and digital circuitry carried by the housing. The digital circuitry operable to assist electronic components of the portable, wireless, communication device in processing digital information to increase a data rate of a wireless communication link.

Claims

1. A cellular telephone comprising:

a battery detachably connectable to the cellular telephone to supply the cellular telephone with power; and

a remote power source detachably connectable to the cellular telephone, wherein the cellular telephone is adapted to sense when the remote power source is coupled to the cellular telephone, the cellular telephone to alter a cellular telephone capability including a rate at which data is transmitted, responsive to sensing the remote power source coupled to the cellular telephone, whereby the cellular telephone, which communicates data at the first data rate, while transmitting, over an air interface independently of the remote power source, is capable of communicating at a higher data rate, while transmitting, only while the remote power source is coupled.

2. The cellular telephone as in claim 1 wherein the battery is operational to deliver a first predetermined voltage level to the cellular telephone, the remote power source operational to deliver a second predetermined voltage level to the cellular telephone, the second predetermined voltage level greater than the first predetermined voltage level.

3. The cellular telephone as in claim 1 wherein the cellular telephone is configured to transmit at a higher average transmit power when the cellular telephone is coupled to the remote power source.

4. A communication assembly, comprising:

a portable wireless communication device including a transceiver for communicating data over a wireless communication link and control circuitry coupled to the transceiver, the control circuitry providing digital data processing to the transceiver, the control circuitry providing digital data processing to the transceiver sufficient to enable the transceiver to communicate data via the wireless communication link at a first data rate, while transmitting; and

an apparatus detachably coupled to the portable wireless communication device, the apparatus including digital circuitry to couple to the control circuitry via a data bus, the digital circuitry interoperable with the control circuitry to provide additional digital data processing support for the control circuitry via the data bus when the apparatus is coupled to the portable wireless device, whereby the digital circuitry operates with the control circuitry to provide digital data processing to the transceiver sufficient to enable the transceiver to communicate data via the wireless communication link at a second data rate, while transmitting, when the apparatus is connected to the communication device, the second data rate being higher than the first data rate.

5. The communication assembly as defined in claim 4, wherein the control circuitry comprises a first microprocessor.

6. The communication assembly as defined in claim 4, wherein the digital circuitry comprises a second microprocessor, the data bus connected between the first and second microprocessors when the apparatus is coupled to the wireless communication device.

7. The communication assembly as defined in claim 4, wherein the apparatus further includes a power source to couple to the communication device, the power source providing additional power when the apparatus is coupled to the wireless communication device.

8. A method of controlling a transceiver in a portable wireless communication device, the method comprising the steps of:

transmitting and receiving wireless communication data from a wireless communication device in a transceiver;

data processing information for transmission and reception via the transceiver in a first processing circuitry in the wireless communication device when an external apparatus is not connected to the wireless communication device, the first processing circuitry enabling wireless data communication via the transceiver at a first data rate, while transmitting; and

cooperative data processing in both the first processing circuitry and a second processing circuitry in an external apparatus information for transmission and reception via the transceiver when the external apparatus including the second processing circuitry is coupled to the communication device, the co-processing enabling wireless data communication via the transceiver at a second data rate, while transmitting, that is higher than the first data rate.

9. The method as defined in claim 8, wherein said step of cooperative processing comprises sharing in the first processing circuitry and the second processing circuitry at least one of coding and decoding of the signals communicated on the communication link when the external apparatus is coupled to the wireless communication device.

10. The method as defined in claim 8, wherein said step of cooperative processing comprises the first processing circuitry providing internet protocol information to the second digital processing circuitry, and the second processing circuitry processing at least one of digital images and web content.
