摘要： In an example embodiment, a system comprises a chain of serially coupled nodes, including a central processing node (CPN) and one or more radio communications nodes (RCNs). The CPN couples to a first RCN in the chain via a dielectric waveguide (DWG) link and any further RCNs in the chain are successively connected in serial fashion from the first RCN via further (DWG) links. The CPN generates outbound radio carrier signals that are waveguide-propagated in a downstream direction of the chain, for over-the-air (OTA) by targeted ones of the RCNs, while radio carrier signals received via OTA reception by respective ones of the RCNs are waveguide propagated as inbound radio signals in an upstream direction of the chain, for processing by the CPN. Advantages from he contemplated system include greatly simplified implementation of the RCNs, with lower cost and power consumption. Further, strategic placement of failover CPNs and DWG links provide for continued operation in the face of CPN or DWG link failures.

摘要： A wireless communication system includes a first communication device and a second communication device. The first communication device obtains a plurality of radio frequency (RF) signals corresponding to different communication protocols from a plurality of communication systems. A frequency of each of the plurality of RF signals is upconverted to a different frequency, and a phase noise is introduced in the plurality of RF signals. The plurality of RF signals corresponding to different communication protocols are multiplexed into a mmWave RF signal of a specified frequency and a defined pilot tone along with the mmWave RF signal is transmitted. The second communication device captures the mmWave RF signal having the defined pilot tone over-the-air. At least one RF signal is down converted to a source frequency and the phase noise is estimated in the one extracted RF signal based on the defined pilot tone which is reduced concurrently.

摘要： The present disclosure provides radio-frequency (RF) systems that can detect the presence of RF signals received by the system, as well as determine characteristics such as the operating frequency of RF signals, the type of RF source that transmitted each RF signal, and/or the location of each RF source with high precision and sensitivity while using low cost, scalable electronics that are versatile enough for deployment in a variety of environments. Such systems can employ a network of RF sensors that can coordinate in response to communication with a computer to perform any such detection and/or determination using trained models executed onboard the RF sensors and/or the computer. RF signals may have unique characteristics when received at one or more RF sensors that may be detected using trained models described herein, even in high noise or non-line of sight (LOS) environments and with low cost, low resolution RF receiver hardware.

摘要： WLAN access point configured to: configure a first wireless extender device not to exceed a hop limit; cause the first wireless extender device to initiate messaging with a root APD via a root fronthaul BSS to receive credentials for a backhaul BSS; cause the first wireless extender device to onboard onto the root APD via the backhaul BSS using the received credentials; enable a second wireless extender device to initiate messaging via the first fronthaul BSS of the first wireless extender device to obtain the credentials for the backhaul BSS; and prevent, in a case that the hop limit has been reached, the second wireless extender device from onboarding onto the backhaul BSS of the first wireless extender device so as to cause the second wireless extender device to onboard onto either the root APD or another wireless extender device.

摘要： A terminal includes a relay unit, a memory, and an access unit. The relay unit relays communication between a different terminal and a server that requires two-step authentication at a time of providing a service. The memory stores first identification information for identifying the different terminal. The access unit accesses the server. In a case where data to be transmitted to the server includes second identification information for identifying the terminal, the access unit transmits the first identification information, in place of the second identification information included in the data, to the server.

摘要： A wireless access point controls Carrier Aggregation (CA) over a wireless repeater chain. The wireless access point exchanges signaling with User Equipment (UE) over the wireless repeater chain which uses a number of repeater hops. The wireless access point selects a radio frequency for a Primary Component Carrier (PCC) based on the number of repeater hops. The wireless access point exchanges user data with the UE over the wireless repeater chain using the selected radio frequency for the PCC. The wireless access point determines uplink throughput for the user data. The wireless access point re-selects the radio frequency for the PCC based on the number of repeater hops and the uplink throughput. The wireless access point exchanges additional user data with the UE over the wireless repeater chain using the re-selected radio frequency for the PCC.
