Abstract: A wireless communication method to alter RF regulatory channel hopping requirements (regulations) between a pair of transceivers is envisioned wherein an embedded transceiver embedded in an RF attenuating medium transmits signals at a lower hopping requirement than a paired open-air transceiver. The communication method adheres to these regulations, which define a threshold power for transmission above which require a high degree of frequency hopping. Because the attenuating medium attenuates the open-air RF signal from the embedded transceiver, channel hopping in the embedded transceiver is lowered however, the channel hopping in the open-air transceiver is not lowered. The two transceivers are essentially powered equally.

Abstract: A bolus that communicates with an external transceiver by way of radio waves produced by an electrically small H-antenna is described. The electrically small H-antenna is connected to a conductive cylindrical antenna that houses a battery and chipset that includes a transceiver, identification information and at least one sensor. The H-antenna and the conductive cylindrical antenna are arranged so that electrical currents that produce the radio waves are essentially always aligned to work together. The bolus is essentially a hermetically sealed capsule containing the antennas that is meant to be ingested by a cow or other ruminant animal. The bolus is configured to transmit radio waves in essentially an omnidirectional pattern more efficiently when the boluses inside of a cow stomach than when the boluses outside of the cow.
