Abstract: Communication device with configurable antenna interface and method for configuring an antenna interface. One implementation of the communication device includes an RF transceiver, a threaded coaxial antenna connector, a first RF terminal, a second RF terminal, an RF signal conduit, and an interface circuit. The threaded coaxial antenna connector includes inner and outer terminals. The RF signal conduit includes a first structure that couples the first RF terminal to the inner terminal of the threaded coaxial antenna connector. The RF signal conduit further includes a second structure that couples the second RF terminal to the outer terminal of the threaded coaxial antenna connector. The interface circuit is configured to set an SMA antenna interface mode by coupling the RF transceiver to the first RF terminal. The interface circuit is also configured to set a ferrule antenna interface mode by coupling the RF transceiver to the second RF terminal.

Abstract: A communication pathway (145) can be established between physically collocated narrowband (135) and broadband (105) devices. The narrowband device (135) can identify a communication channel. A transmission frequency used by the broadband device (105) can be spectrally-proximate to a reception frequency used by the narrowband device (135) in a frequency range associated with the communication channel, resulting in interference of the narrowband device's (135) reception when the broadband device (105) is transmitting and the narrowband device (135) is receiving concurrently. The narrowband device (135) can instruct the broadband device (105) to switch to a transmission spectrum block that is spectrally separated from the reception spectrum block of the communication channel to minimize interference between the devices when the narrowband device (135) handles a call assignment.

Abstract: A communication system (100) is facilitated by an access node (102) to support communication with subscriber units (104, 106) as secondary users of a regulated spectrum portion. The access node requests permission to operate as a secondary user from an authorization server (118). The authorization server provides authorized transmission parameters based on characteristics of the access node. The access node operates according to the authorized transmission parameters and provides the parameters to eligible subscriber units.

Abstract: A remote microphone display select system (200) used with a two-way radio (201) for controlling the orientation of displayed information includes a remote microphone (101) which is electrically connected to a display driver (203). A hall effect switch (207) is used with the display driver (203) and acts to alter the orientation of displayed information on a display (106) to either a first orientation or second orientation when the hall effect switch (207) is disabled.

Abstract: A noise signal is obtained from a data processor output, such as a data line, an address line, or a control line, and used to control the frequency modulation of an oscillator. The modulated output is used to clock the data processor.

Abstract: A radio (100) capable of automatically selecting an encryption algorithm from among a plurality of algorithms (122 and 124) is disclosed. The method for automatically selecting the proper encryption hybrid includes the steps of: attempting to decrypt the encrypted signal with one of the plurality of encryption algorithms; determining if the encryption algorithm used to decrypt the encrypted signal matches the encryption algorithm used by the encrypted signal; and developing a control signal upon the proper matching of the encryption algorithms.

Abstract: A decryption device wherein an encryption/decryption module can be operated at various clock speeds, and wherein an associated processor controls these clock speeds depending upon the moment to moment processing interrelationship between the encryption/decryption module and the processor. In particular, when loading a new key into the encryption module, or when utilizing the encryption module to decrypt an encrypted new key, the processor alters the usual clock rate for the encryption module.
