Abstract: An environmental frequency sensing device, includes logic that performs signal strength (SS) level separation on a received band of frequencies to produce SS level separated frequencies. The logic performs frequency grouping on the SS level separated frequencies for each signal strength level to produce magnitude information for each grouping. The logic generates peak data by detecting peaks of the produced magnitude information. The logic generates an edge event indicating a signal edge based on arrival or departure of a given peak and compares, on a frequency basis, generated edges to stored fingerprint data of a signal of interest. Based on the comparison, the logic provides detected signal data indicating current use of a range of frequencies in an environment.

Abstract: In the presence of a network fault condition preventing communication between a communication device and a network device of a first network, a method includes receiving a heartbeat request from the communication device requesting permission for the communication device to perform a device operation. The method further includes obtaining device state data associated with the communication device and determining whether the communication device is permitted to perform the device operation based on the device state data associated with the communication device. When the communication device is permitted to perform the device operation, the method also includes transmitting a heartbeat confirmation signal to the communication device. The heartbeat confirmation signal permits the communication device to perform the device operation.

Abstract: In the presence of a network fault condition (130) preventing communication between a communication device (106) and a network device (200) of a first network (102), a method (400) includes receiving a heartbeat request (128) from the communication device requesting permission for the communication device to perform a device operation. The method further includes obtaining device state data (110) associated with the communication device and determining whether the communication device is permitted to perform the device operation based on the device state data associated with the communication device. When the communication device is permitted to perform the device operation, the method also includes transmitting a heartbeat confirmation signal (126) to the communication device. The heartbeat confirmation signal permits the communication device to perform the device operation.
