Abstract

A device is provided that is capable of simultaneous communication over multiple wired and wireless networks. The device is capable of processing data received simultaneously over multiple networks by storing the data in data buffers and using a polling routine to retrieve the data from the data buffers. The device is capable of preventing interference when communicating over multiple wireless networks in the same frequency band by monitoring the frequency channel used by one of the wireless networks and controlling the frequency channels used by the other wireless networks.

Claims

1. A device for communicating over at least two wireless communication interfaces comprising:

a first communication interface operating at one of a plurality of frequency channels within a frequency band;

a second communication interface operating at one of the plurality of frequency channels within the frequency band; and

a communication controller for determining which one of the plurality of frequency channels the first communication interface is operating and for directing the second communication interface to operate at a different one of the plurality of frequency channels from that which the first communication interface is operating.

2. The device of claim 1 wherein the first communication interface and the second communication interface are chosen from the group comprising wireless Ethernet, Bluetooth, and general packet radio service.

3. The device of claim 1 wherein the first communication interface is wireless Ethernet and the second communication interface is Bluetooth.

4. The device of claim 1 wherein the frequency band is 2.4 GHz.

5. The device of claim 1 wherein the device is a portable printer.

6. A device for communicating over at least two communication interfaces comprising:

a first communication interface having a first communication driver and a first data buffer such that the first communication driver retrieves first data from the first communication interface and stores the first data in the first data buffer;

a second communication interface having a second communication driver and a second data buffer such that the second communication driver retrieves second data from the second communication interface and stores the second data in the second data buffer;

a main processor for retrieving data by polling the first and second data buffers and for processing the data, such that the main processor retrieves first data from the first data buffer, then retrieves second data from the second data buffer, then processes the first and second data.

7. The device of claim 6 wherein the first communication interface and the second communication interface are chosen from the group comprising wireless Ethernet, Bluetooth, general packet radio service, serial, and universal serial bus.

8. The device of claim 6 wherein the device is a portable printer.

9. A printer comprising:

a housing including a core printer assembly wherein the core printer assembly includes a media support assembly, a drive assembly, and a print head assembly; and

a communication interface, wherein the communication interface is configured to provide functional support for a plurality of wireless communication devices selected from the group consisting of a wireless Ethernet device, a Bluetooth device, and a general packet radio service device.

10. The printer of claim 9, wherein the plurality of wireless communication devices comprises a first wireless communication device and a second wireless communication device, and wherein the printer further comprises a communication controller for determining which one of a plurality of frequency channels within a frequency band the first wireless communication device is operating and for directing the second wireless communication device to operate at a different one of the plurality of frequency channels within the frequency band from that which the first wireless communication device is operating.

11. The printer of claim 10, wherein the first wireless communication device is a wireless Ethernet device and the second wireless communication device is a Bluetooth device.

12. The printer of claim 10, wherein the frequency band is 2.4 GHz.

13. The printer of claim 9, wherein the plurality of wireless communication devices comprises a first wireless communication device and a second wireless communication device, and wherein the printer further comprises a first communication driver and a first data buffer such that the first communication driver retrieves first data from the first wireless communication device and stores the first data in the first data buffer, and wherein the printer further comprises a second communication driver and a second data buffer such that the second communication driver retrieves second data from the second wireless communication device and stores the second data in the second data buffer, and wherein the printer further comprises a main processor for retrieving data by polling the first and second data buffers and for processing the data, such that the main processor retrieves first data from the first data buffer, then retrieves second data from the second data buffer, then processes the first and second data.

14. The printer of claim 13, wherein the communication interface is further configured to provide functional support for a plurality of wired communication devices selected from the group consisting of a serial device and a universal serial bus device.
