Abstract

A radio module that detachably connects with a host device. A radio module is provided that includes an antenna as an integral part of the radio module. The antenna satisfies regulatory requirements by being an integral part of the radio module. The radio module includes an interface circuit that provides the processing required for communication over a wireless network. The functionality of the interface can be divided between the radio module and the host device. The physical interface between a host device and the radio module may depend on which functions are implemented by the radio module and which functions are implemented by the host device. In one example, the physical interface is a standard connection that permits the radio module to be detachably connected with multiple devices. The radio module also includes a flexible cable such that the radio module can be optimally positioned within the wireless network.

Claims

1. A method for positioning a radio module that is utilized by one or more devices in a wireless network, wherein performance of the radio module varies based on position of the radio module within the wireless network, the method comprising:

providing an antenna module that includes an antenna and is an integral part of the radio module;

providing a plurality of other modules including a baseband module that performs demodulation and decoding on signals received over the antenna module and that performs modulation and coding on signals transmitted by the antenna module;

providing a first interface that is configured to directly connect one of the plurality of other modules with a host device when the first interface is in use;

providing a second interface that is configured to directly connect another of the plurality of other modules to the host device when the second interface is in use; and

providing a physical interface that detachably connects the radio module with the host device such that the radio module may be positioned within the wireless network without fixing the host device'"'"'s location.

2. A method as defined in claim 1, wherein the antenna module receives power from the host device through the physical interface.

3. A method as defined in claim 1, wherein the plurality of other modules comprises a host interface module.

4. A method as defined in claim 3, wherein the host interface module comprises a USB interface.

5. A method as defined in claim 3, wherein the host interface module comprises an Ethernet interface.

6. A method as defined in claim 3, wherein the host interface module comprises a IEEE 1394 interface.

7. A method as defined in claim 3, wherein the host interface module provides store and forward capabilities.

8. A method as defined in claim 1, wherein the plurality of other modules comprises a wireless data link layer module.

9. A method as defined in claim 1, wherein the plurality of other modules comprises a wireless media access control module.

10. A method as defined in claim 1, wherein the method further comprises optimally positioning the radio module within the wireless network independent of the host device.

11. A method as defined in claim 10, wherein the physical interface comprises a cable that permits the radio module to be optimally positioned within the wireless network independent of the host device.

12. A radio module as defined in claim 10, wherein the method further comprises indicating to a user when the radio module is optimally positioned within the wireless network.
