The present disclosure is directed towards a method of changing wireless communication channels in a connected host and client system. For example, in one embodiment, the link quality of a connection is monitored by the host or the client. If the connection has a link quality below a predetermined threshold but remains intact, a channel switch request is sent, synchronization packages are exchanged between the host and client on the current channel, the channel of the system is changed to a new channel, and the system resumes communications on the new channel.

1. A method for changing wireless communication channels in a connected host and client system comprising: sending and receiving data via a connection;monitoring the link quality of the connection and determining if the connection remains intact;when the connection has a link quality below a predetermined threshold but remains intact, performing operations comprising: sending a channel switch request and receiving a channel switch response via the connection,changing the channel of the system to a new channel, andresuming system communication on the new channel. 2. The method of claim 1, wherein the link quality is determined by the host or client monitoring one or more of signal to noise ratio, signal strength, number of packages failing data verification, or number of dropped packages. 3. The method of claim 1, wherein the channel switch request indicates the new channel to which the requestor intends to change. 4. The method of claim 1, wherein the channel switch request indicates a number of synchronization packages to be exchanged before changing to the new channel. 5. The method of claim 4, wherein, exchanging synchronization packages comprises: the host successively delivering synchronization packages to the client, each synchronization package comprising a decrementing count of the number of synchronization packages remaining, andthe host successively receiving the synchronization packages back from the client until the count of the number of synchronization packages remaining has reached the count-down target. 6. The method of claim 1, wherein either the host or client device drops the connection to the other device after sending the channel switch request. 7. The method of claim 1, wherein, when the connection does not remain intact, operations are performed, comprising: the host device selecting the new channel and broadcasting a beacon on the new channel,the client device scanning channels until the new channel is located where the beacon of the host is detected, andthe host and client reconnecting on the new channel to resume system communication. 8. An imaging host device comprising: an X-ray source;circuitry configured to control the emission of radiation from the X-ray source;one or more wireless communication interfaces comprising circuitry configured to: exchange data with a detector client over a connection;monitor a link quality of the connection to the detector client and determine if the connection remains intact;when the link quality of the connection is below a predetermined threshold but remains intact, perform operations comprising:sending a channel switch request to the detector client via the connection,receiving a channel switch response from the detector client via the connection,establishing a new connection on a new wireless channel based on the channel switch request, andresuming system communication via the new connection. 9. The device of claim 8, wherein the channel switch request indicates a new channel number corresponding to the new channel selected by the host. 10. The device of claim 8, wherein the channel switch request indicates a number of synchronization packages to be exchanged before changing to the new channel. 11. The device of claim 10, wherein, exchanging synchronization packages comprises the host successively delivering a synchronization package to the detector client, and then receiving a synchronization package response from the detector client until a count of the number of synchronization packages remaining has reached a count-down target. 12. The device of claim 8, wherein the host drops the connection to the detector client after sending the channel switch request to the detector client. 13. The device of claim 8, wherein, when the connection does not remain intact, a series operations are performed comprising: selecting the new channel, andcontinuously broadcasting a beacon on the new channel until it is located by the detector client, andconnecting to the detector client on the new channel. 14. A portable client device comprising wireless communication circuitry configured to: exchange data with a host via a wireless connection;monitor a link quality of the wireless connection to the host and determine if the connection remains intact;when the wireless connection has a link quality below a predetermined threshold but remains intact, send a channel switch request to the host via the wireless connection; andwhen the channel switch request is received by the host, exchange a number synchronization packages with the host on the current channel, change to a new channel specified in the channel switch request, and then resume exchanging data with the host on the new channel. 15. The device of claim 14, wherein the client device is a portable X-ray detector client comprising circuitry configured to detect and transduce emissions from a radiation source into a portion of the data exchanged with the host. 16. The device of claim 14, wherein the client device is a portable patient sensor client comprising circuitry configured to perform measurements of physical attributes of a patient, wherein these measurements comprise a portion of the data exchanged with the host. 17. The device of claim 14, wherein a channel switch request received from the host comprises one or both of a new channel number corresponding to the new channel or the number of synchronization packages to be exchanged. 18. The device of claim 14, wherein, exchanging synchronization packages comprises the client device successively receiving a synchronization package from the host and then sending a synchronization package response back to the host until a number of synchronization packages remaining equals a count-down target. 19. The device of claim 14, wherein the client device drops the wireless connection to the host after sending the channel switch request to the host. 20. The device of claim 14, wherein, when no wireless connections to the host are currently present, the wireless communication circuitry is configured to perform a series of operations comprising: searching different channels until an active channel with a beacon from the host is located, andconnecting to the beaconing host on the active channel, and resuming exchanging data with the host via the active channel.
