Abstract: A land mobile radio (LMR) device may be used with a cellular device in communication with a push-to-talk-over-cellular (POC) network. The LMR device may include an LMR processor, an LMR memory, an LMR local communication interface configured to communicate with the cellular device, and a channel selection input. The LMR processor may be configured to retrieve channel configuration information defining one or more POC channels from the cellular device via the LMR local communication interface and store the channel configuration information in the LMR memory. The channel selection input may be configured to select a selected channel from the one or more POC channels defined by the channel configuration information. The LMR local communication interface may be configured to communicate with the POC network over the selected channel via the cellular device.

Abstract: A method for configuring a land mobile radio (LMR) may include providing a hub device and providing a destination LMR device. The hub device may include a hub memory, a hub communication interface, and a hub processor operably coupled to the hub memory and the hub communication interface. The destination LMR device may include a destination LMR memory, a LMR destination communication interface, and a LMR destination processor operably coupled to the destination LMR memory and the destination LMR communication interface. The method may further include storing a configuration parameter in the hub memory, establishing communication between the hub communication interface and the destination LMR communication interface, transmitting the configuration parameter from the hub memory to the destination LMR memory, and controlling the destination LMR device to implement the configuration parameter.

Abstract: A P25 radio can be configured to implement a key management facility to thereby manage keysets for and provision the keysets on other P25 radios in a communications system. The P25 radio, as a radio, can directly communicate with the other P25 radios to provision keysets in accordance with the OTAR protocol. The P25 radio may also be configured to function as a key fill device to thereby provision keysets manually on any of the other P25 radios to which it may be physically or wirelessly connected. The P25 radio may also be configured to use the keysets to communicate securely with any of the other P25 radios.

Abstract: Public safety official accessories, such as remote speaker microphones and body cameras, can include an infrared thermometer for enabling public safety officials to detect whether individuals have fevers. Temperature readings obtained using the public safety official accessories can be output to a display of a radio or of the public safety official accessory. By integrating an infrared thermometer into a public safety official accessory, the public safety official can discreetly determine whether an individual has a fever.
