1. A wireless network node comprising:
- a transceiver configured to wirelessly receive a first repeating isochronous signal having an isochronous transmission period and a second repeating isochronous signal having an isochronous transmission period; and
a processing system coupled with the transceiver, the processing system configured todetermine the isochronous transmission period of the first repeating isochronous signal based on a timing of the received first repeating isochronous signal, the first repeating isochronous signal forming an established isochronous communication channel;
selectively activate and deactivate the transceiver based on the determined isochronous transmission period of the first repeating isochronous signal to generate a duty cycle including one or more search windows, the one or more search windows spaced in time such as to not interfere with the reception of the first repeating isochronous signal; and
identify the second repeating isochronous signal received by the transceiver during at least one search window;
wherein the one or more search windows are spaced according to the determined isochronous transmission period of the first repeating isochronous signal.

Abstract
A network including a plurality of nodes each configured as transmitters, receivers, or transceivers. At least one of the nodes may be configured to wirelessly transmit a repeating isochronous signal for reception by one or more of the other nodes. The isochronous phase and/or frequency of the repeating isochronous transmission may be variably adjusted to reduce signal interference.

10. A method of searching for a transmitted isochronous signal, the method comprising:
-
wirelessly receiving, using a transceiver, a first repeating isochronous signal having an isochronous transmission period and a second repeating isochronous signal having an isochronous transmission period; determining, using a processing system coupled with the transceiver, the isochronous transmission period of the first repeating isochronous signal based on a timing of the received first repeating isochronous signal, the first repeating isochronous signal forming an established isochronous communication channel; selectively activating and deactivating the transceiver, using the processing system, based on the determined isochronous transmission period of the first repeating isochronous signal, to generate a duty cycle including one or more search windows, the one or more search windows spaced according to the determined isochronous transmission period of the first repeating isochronous signal such as to not interfere with the reception of the first repeating isochronous signal by the transceiver; and identifying the second repeating isochronous signal received by the transceiver during at least one search window. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A wireless network comprising;
-
a first wireless network node configured to transmit a first repeating isochronous signal having an isochronous transmission period; a third wireless network node configured to transmit a second repeating isochronous signal having an isochronous transmission period; and a second wireless network node including; a transceiver configured to wirelessly receive the first repeating isochronous signal and the second repeating isochronous signal; and a processing system coupled with the transceiver, the processing system configured to determine the isochronous transmission period of the first repeating isochronous signal based on a timing of the received first repeating isochronous signal, the first repeating isochronous signal forming an established isochronous communication channel; selectively activate and deactivate the transceiver based on the determined isochronous transmission period of the first repeating isochronous signal to generate a duty cycle including one or more search windows, the one or more search windows spaced in time such as to not interfere with the reception of the first repeating isochronous signal; and identify the second repeating isochronous signal received by the transceiver from the third wireless network node during at least one search window; wherein the one or more search windows are spaced according to the determined isochronous transmission period of the first repeating isochronous signal. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
