Abstract: Embodiments described herein relate to apparatuses and methods for registering and storing a local key associated with a local application of a communication device, including, but not limited to, receiving a request from the communication device to register and store the local key, evaluating the request based on at least one first policy, and sending the request to register and store the local key to a secure key storage.

Abstract: Reliable transmission of signals in a multi-channel system is achieved by transferring signal inputs from a defectively operating or inoperative transmitter to another transmitter which continues to transmit other channels. At least two transmitters are operated normally, each transmitting its own block of channels. A sensor detects when the output of one transmitter is improper or non-existent, and causes a change-over switch to operate. Operation of the switch adds the block of channels which had come from the one transmitter to the other (or one or more) of the transmitters, so that the remaining transmitter or transmitters now provide all the channels.

Abstract: A combination of broadband program materials, such as TV, plus digital communications services of all types, are broadcast to a cell in the same frequency band, such as 27.5 to 28.5 GHz. The combination of all the transmitted channels have a combined bandwidth substantially exceeding the frequency band. At least some of the channels are transmitted with two diversity characteristics different from those of other channels. In one embodiment analog signals transmit the broadband services, preferably using wide deviation FM modulation, the FM channels filling the band. By choosing carrier frequencies selectively, between 5 and 9 T-1 digital channels can be broadcast in each FM channel when polarization is the same. Differing polarization of digital and FM signals in the same band can enable selection and detection of the desired one of a full spectrum of digital signals, or any one of the analog signals.
