    摘要： A mobile tracking unit includes a controller having a processor, a memory in electronic communication with the processor, and instructions stored in the memory. The instructions are executable by the processor to communicate with a control unit of an automation and security system, determine a position of the mobile tracking unit relative to a base station using a low power location module, and communicate the position of the mobile tracking unit to at least one of the base station and a control unit of the automation and security system. When the mobile tracking unit is outside a specified range from the mobile tracking unit, the controller continues tracking the position of the mobile tracking unit with the low power location module. When the mobile tracking unit is inside the specified range, the controller determines the position of the mobile tracking unit using a high power location module.

    摘要： This disclosure relates to a devices and methods related to satellite information broadcasting. Example embodiments may include frequency shifting an intermediate frequency (IF) signal down-conversion from the microwave-band. As an example, down-conversion involving local oscillators may lead to frequency drift due to varying temperature and/or humidity conditions. Correcting for the frequency drift may provide an opportunity to remove or filter excess bandwidth. Further embodiments may include receiving, in a tuning request, information about a transponder type. A frequency translation module may be adjusted based, at least in part, on the transponder type related to the IF signal being input into the frequency translation module. Such frequency-shifting and transponder-specific filtering may allow Single-Wire Multiswitch (SWM) devices to provide output signals with narrower bandwidth, which may improve signal quality, cable run length, reduce power demands, etc.
