Abstract

Embodiments discussed herein refer to systems, methods, and circuits for managing and establishing contactless communications lanes between two contactlessly coupled systems. A contactless communication lane can be formed for each coupled pair of contactless communication units existing in the two systems. A contactless communications interface can enable software-defined connectivity that manages use of the contactless communication data lanes to enable data communications according to a selected one of a plurality of communications interfaces. The contactless communications interface may serve as a protocol translator and virtualization layer for enabling higher level software such as an operating system of a first system to communicate with a second system without requiring interface protocol specific hardware and software. This advantageously simplifies hardware and software components needed to simultaneously service a multitude of interface protocols.

First claim

What is claimed is:

1. A contactless communications interface (CCI) for use in a system comprising a plurality of contactless extremely high frequency (EHF) transceivers, the CCI comprising:
a plurality of communications interface lanes (CILs) coupled to transmit data to and receive data from the plurality of contactless EHF transceivers, wherein each CIL is associated with a respective one of the plurality of contactless EHF transceivers;
a bandwidth allocation module that controls downstream data capacity and upstream data capacity of the plurality of CILs, wherein a total available bandwidth depends on the number of the plurality of contactless EHF transceivers that are in contactless communication with reciprocal contactless EHF transceivers;
a quality of service module that manages performance metrics by controlling usage of the plurality of CILs; and
a lane usage module that controls the directional flow of data through the plurality of CILs, wherein the lane usage module is controlled by the bandwidth allocation module and the quality of service module.

2. The CCI of claim 1 , wherein the bandwidth allocation module controls the downstream data capacity and the upstream data capacity of the plurality of CILs based on requirements of the system for downstream and upstream bandwidth usage.

3. The CCI of claim 1 , wherein the bandwidth allocation module configures each CIL to be one of a downstream only CIL, an upstream only CIL, a bidirectional CIL, and a null CIL.

4. The CCI of claim 1 , wherein the quality of service module specifies minimum bandwidth usage requirements of a service or application being implemented by the system.

5. The CCI of claim 1 , wherein the quality of service module manages usage of the plurality of CILs based on user preferences, operating system requirements, or hardware requirements.

6. The CCI of claim 1 , wherein each CIL comprises:
a contactless LINK layer; and
a contactless PHY layer.

7. A method for using a contactless communications interface (CCI) being implemented in a system comprising a plurality of contactless extremely high frequency (EHF) transceivers and a plurality of communications interface lanes (CILs) coupled to transmit data to and receive data from the plurality of contactless EHF transceivers, wherein each CIL is associated with a respective one of the plurality of contactless EHF transceivers, the method comprising:
controlling downstream data capacity and upstream data capacity of the plurality of CILs with a bandwidth allocation module, wherein a total available bandwidth depends on the number of the plurality of contactless EHF transceivers that are in contactless communication with reciprocal contactless EHF transceivers;
managing performance metrics according to a quality of service module by controlling usage of the plurality of CILs; and
controlling the directional flow of data through the plurality of CILs with a lane usage module, wherein the lane usage module is controlled by the bandwidth allocation module and the quality of service module.

8. The method of claim 7 , wherein controlling the downstream data capacity and the upstream data capacity of the plurality of CILs is based on requirements of the system for downstream and upstream bandwidth usage.

9. The method of claim 7 , further comprising configuring, via the bandwidth allocation module, each CIL to be one of a downstream only CIL, an upstream only CIL, a bidirectional CIL, and a null CIL.

10. The method of claim 7 , further comprising specifying, via the quality of service module, minimum bandwidth usage requirements of a service or application being implemented by the system.

11. The method of claim 7 , further comprising managing, via the quality of service module, usage of the plurality of CILs based on user preferences, operating system requirements, or hardware requirements.

12. A system comprising:
a plurality of contactless extremely high frequency (EHF) transceivers; and
a contactless communications interface (CCI) comprising:
a plurality of communications interface lanes (CILs) coupled to transmit data to and receive data from the plurality of contactless EHF transceivers, wherein each CIL is associated with a respective one of the plurality of contactless EHF transceivers;
a bandwidth allocation module that controls downstream data capacity and upstream data capacity of the plurality of CILs, wherein a total available bandwidth depends on the number of the plurality of contactless EHF transceivers that are in contactless communication with reciprocal contactless EHF transceivers;
a quality of service module that manages performance metrics by controlling usage of the plurality of CILs; and
a lane usage module that controls the directional flow of data through the plurality of CILs, wherein the lane usage module is controlled by the bandwidth allocation module and the quality of service module.

13. The system of claim 12 , wherein the bandwidth allocation module controls the downstream data capacity and the upstream data capacity of the plurality of CILs based on requirements of the system for downstream and upstream bandwidth usage.

14. The system of claim 12 , wherein the bandwidth allocation module configures each CIL to be one of a downstream only CIL, an upstream only CIL, a bidirectional CIL, and a null CIL.

15. The system of claim 12 , wherein the quality of service module specifies minimum bandwidth usage requirements of a service or application being implemented by the system.

16. The system of claim 12 , wherein the quality of service module manages usage of the plurality of CILs based on user preferences, operating system requirements, or hardware requirements.

17. The system of claim 12 , wherein each CIL comprises:
