    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.
