Abstract: An ultrawideband radio transceiver/repeater provides a low cost infrastructure solution that merges wireless and wired network devices while providing connection to the plant, flexible repeater capabilities, network security, traffic monitoring and provisioning, and traffic flow control for wired and wireless connectivity of devices or networks. The ultrawideband radio transceiver/repeater can be implemented in discrete, integrated, distributed or embedded forms.

Plain-Language Overview of Independent Claims

This patent has one independent claim:

• Claim 1: This claim describes a wireless repeater device designed for ultrawideband (UWB) communication. The key features of this device include:
  • The ability to receive UWB signals with a bandwidth of at least 100 MHz.
  • The capability to process the received signals to identify and filter out unwanted data from interfering sources.
  • A function to store the received data.
  • The ability to re-transmit the filtered data, effectively "repeating" the desired communication to extend its range.
  • The capacity to be controlled or have its settings adjusted based on instructions received over the wireless network.

In essence, the claim outlines a smart UWB repeater that can not only extend the range of a wireless network but also intelligently manage the traffic by filtering out interference and can be remotely managed.
