Abstract: Methods for determining calibration parameters to correct for frequency responses of one or more dielectric waveguides coupling a control unit to a first antenna node or to a series of antenna nodes that includes the first antenna node. An example method comprises transmitting, via a first dielectric waveguide coupling the control unit to the first antenna node, a radiofrequency (RF) test signal having a signal bandwidth covering a bandwidth of interest. The method further comprises receiving, via a second dielectric waveguide coupling the control unit to the first antenna node, a looped-back version of the transmitted RF test signal, and estimating a first one-way frequency response corresponding to the first (or second) dielectric waveguide, based on the RF test signal and the received loop-back version of the transmitted RF test signal.

Abstract: 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.

Abstract: A first aspect provides in a supply voltage control module, a method of providing instructions for setting a supply voltage comprising obtaining information on a supply voltage need of a load and based on that information, determining a supply voltage that is to be provided to the load. Subsequently, an instruction is sent to a power supply module to supply the determined supply voltage to the load. A need for a supply voltage of a load, like an integrated circuit, may not only depend on design of the load, but also on parameters of the manufacturing process and the level of activity of the load. By obtaining information on a supply voltage need of the load and using that information to determine a supply voltage to be provided to the load, a feedback loop is created by instructing a point of load power supply to provide the supply voltage determined.
