Abstract: One example Land Mobile Radio (LMR) base station includes a network interface and an electronic processor. The electronic processor is configured to receive profile information of a plurality of fifth generation (5G)/Long Term Evolution (LTE) communication devices. The profile information of the plurality of 5G/LTE communication devices may be transmitted (i) over a background gateway communication channel to an LMR communication network that includes the LMR base station and (ii) in response to the 5G/LTE software defined network detecting a fault condition of the first 5G/LTE communication network. The electronic processor is further configured to broadcast a capture beacon based on the profile information and compliant with at least some characteristics of a 5G/LTE communication protocol. The capture beacon is configured to be received by the 5G/LTE communication device to reconfigure the 5G/LTE communication device for communication compliant with an LMR communication protocol.

Abstract: A method of controlling a converged communications device. The method includes executing a first call between the converged communications device and a first network using a first communication modality, audibilizing the first call with one of an earpiece speaker and a loudspeaker, receiving a second call from a second network having a second communication modality different from the first communication modality, sensing an action by a user in response to receiving the second call, and audibilizing the second call with the other of the earpiece speaker and the loudspeaker based on the action and based on the second communication modality. Also discloses is a converged communications device performing the method.

Abstract: An open waveguide antenna for a radio frequency identification reader includes a conductive annular waveguide concentric about an axis and configured for operation within an operating frequency band. A radiating slot is formed in at least one wall of the waveguide is also concentric about the axis. An odd-multiple of ports are electrically coupled to the annular waveguide, where the ports are equally spaced around the waveguide at a spacing between adjacent ports of one-half of a guided wavelength at a center frequency of the operating band. A second waveguide, smaller than the first, can also be incorporated. The second waveguide can have a different slot arrangement and fewer ports. The rectangular waveguides can operate in a non-transverse electromagnetic mode, and the ports can be individually driven to beamform the radiated signal of the antenna.
