A power and data housing assembly includes a housing body configured to retain and support an electrical device assembly in the form of a radio frequency (RF) transmitter. The RF transmitter is configured to emit a transmitted RF signal that contains one of data transmissions and power transmissions, and acts as a repeater and/or range-extender or signal redirector for directing wireless power and/or data signals into regions of work areas that otherwise would receive only marginal signals, or none at all.

Systems and devices are provided in which an RF wireless bridge is employed to facilitate indirect transmission of communication signals between external devices located outside of an electromagnetically shielding enclosure within internal devices located within the enclosure, via the intermediate transmission of RF waves through an RF attenuating window forming a portion of the enclosure. The wireless bridge is formed from a first RF communication device located within the electromagnetically shielding enclosure, and a second RF communication device located outside of the enclosure, where the two RF communication devices are positioned with sufficient proximity such that the wireless bridge facilitates indirect communication through the RF attenuating window despite attenuation of RF energy by the RF attenuating window. In another example embodiment, the electromagnetically shielding enclosure may enclose at least a portion of the first RF communication device to reduce noise that could impact the performance of the magnetic resonance scanner.

There is provided a relay device for relaying communication between a radio base station and a communication terminal, the relay device including a relay function management switch that switches on and off a relay function for relaying communication between a radio base station and a communication terminal of a relay means; and a change command transmitter that transmits, to the communication terminal, a change command of a handover threshold for the communication terminal establishing a wireless communication connection with the relay device when the relay function management switch switches the relay function off.

Embodiments of the present disclosure support a head-mounted display (HMD) wirelessly coupled to a console. The HMD includes a positional tracking system, a beam controller and a transceiver. The positional tracking system tracks position of the HMD and generates positional information describing the tracked position of the HMD. The transceiver communicates with a console via a wireless channel, in accordance with communication instructions, the communication instructions causing the transceiver to communicate over one directional beam of a plurality of directional beams. The beam controller determines a change in the positional information. Based on the change to the positional information, the beam controller determines a directional beam of the plurality of directional beams. The beam controller further generates the communication instructions identifying the determined directional beam, and provides the communication instructions to the transceiver.

A decentralized communication device is provided that facilitates optimal positioning and orientation of one or more antennas for wireless communication with external devices. The decentralized communication device includes one or more master components and one or more slave components. The master and the slave components are physically separate and communicate wirelessly. In some embodiments the slave acts as a carrier frequency translator between the master and an external wireless device, where it communicates with the external device using a first frequency and communicates with the master using a second frequency which is different from the first frequency. In another embodiment the slave has most or all the physical layer to do the digital coding, digital modulation, data framing, data formatting and data packetization for communicating with an external device, in which case digital coding and digital modulation is distributed between the master and the slave.
