    Abstract: Radio frequency architecture for reducing mutual interference between multiple wireless communication modalities. One embodiment provides a portable communications device including a housing and an RF antenna system including a first RF antenna, a second RF antenna, and a third RF antenna in the housing. The portable communications device includes an RF transceiver system including a first RF transceiver, a second RF transceiver, and a third RF transceiver operating in respective bands and an isolator circuit coupled to the RF antenna system and the RF transceiver system and configured to provide RF isolation between the first RF transceiver, the second RF transceiver, and the third RF transceiver. The isolator circuit includes an RF coupler featuring six RF coupler ports coupled to the first RF antenna, the second RF antenna, the third RF antenna, the first RF transceiver, the second RF transceiver, and the third RF transceiver through respective phasor shaping networks.

    Abstract: An antenna system. The antenna system includes a central antenna, and a plurality of peripheral antennas positioned symmetrically around the central antenna. A first coupler provides a first radio connection and a second radio connection. A first 180 degree hybrid coupler is coupled to a first two diametrically opposed antennas of the plurality of peripheral antennas. A second 180 degree hybrid coupler is coupled to a second two diametrically opposed antennas of the plurality of peripheral antennas. A third 180 degree hybrid coupler coupled to the first and second 180 degree hybrid couplers, and having a third radio connection and a fourth radio connection. The first, second, third, and fourth radio connections are decoupled from each other, and the first, second, and third system radio connections are also decoupled from the central antenna.

    Abstract: A short, efficient antenna utilizing a floating coax transmission line over ground or overlapping wire feed structure for reduced antenna size for use in handheld radios. An asymmetric transmission line radiator having a length (LTL) is oriented substantially planar to and proximal to a truncated ground plane, and having at one end an input/output connector, and at an other end a feed point at least one of above a ground plane and proximal to its edge. An exciter antenna in a form of a plate or bent wire is coupled to the feed point and is exterior to the edge of the ground plane and oriented substantially orthogonal to the ground plane, the exciter antenna having a larger dimension length (LEA) that is at least 50% smaller than the length LTL. The overall length of a perimeter of the antenna is approximately ½ a wavelength of a center frequency of the antenna.

    Abstract: Systems and methods for dynamically updating and distributing digital reconnaissance maps for incident response. One example system includes an electronic processor coupled to an electronic communication interface. The processor is configured to receive an incident notification for an incident occurring at an incident scene and to generate a reconnaissance map for the incident scene. The processor is configured to receive a voice communication associated with a first incident responder at the incident scene and determine, for the first incident responder, a location within the incident scene. The processor is configured to determine a location status for the location based on the voice communication and to generate an updated reconnaissance map for the incident scene based on the reconnaissance map, the location, and the location status. The processor is configured to send, via the communication interface, the updated reconnaissance map to an electronic communication device associated with a second incident responder.

    Abstract: One example cloud-based electronic computing device includes and electronic processor and communicates over a wireless communication network with a User Equipment (UE) device. The electronic processor receives public safety incident information about a public safety incident from a public safety command center. The electronic processor receives metadata representing first gathered data from a location of the public safety incident from the UE device. The electronic processor may determine, based on the public safety incident information and the metadata, whether to process the first gathered data by a first UE device at the location of the public safety incident or by the electronic processor of the cloud-based electronic computing device.
