AI summary
A wired network may be used to carry signals for a wireless network, in a frequency-shifted manner, to extend the range of the wireless network. A wired network may detect signal interference emanating from a wireless service provider, and received through a leak in the wired network's infrastructure. Devices may be installed or leveraged in the vicinity of the interference to extend the wireless service to geographic areas that may have poor reception. The devices may amplify wireless downstream signals and transmit them wirelessly, and may receive upstream wireless communications and transmit them upstream in the wired network's protocol.
