Patent number: 11968581Abstract: Because of the line-of-sight character of optical wireless communication and a limited field-of-view of optical receivers, the coverage of an access point and the overlapping coverage area of adjacent access points in an optical system are smaller as compared to a RF system. It turns more challenging to support an end point (110) to roam securely in an optical multi-cell wireless communication network. To speed up the derivation of a new pairwise transient key with a new access point during a handover procedure, the end point of this invention comprises a controller (118) that is configured to act as a second supplicant (1181), on behalf of a first supplicant (1186) comprised in a host processor (1185), to communicate with an authenticator to establish a new pairwise transient key for the end point (110) and a candidate access point, and an active pairwise transient key with the currently associated access point is used to secure the communication for new key derivation.Type: GrantFiled: March 1, 2021Date of Patent: April 23, 2024Assignee: SIGNIFY HOLDING B.V.Inventors: Andries Van Wageningen, Piotr Polak, Sahil Sharma

Patent number: 11968133Abstract: In a LiFi network with multiple coordinators, interference in the overlapping areas between the local parts of the network can occur if each coordinator determines its own local time schedule for communicating with devices. To solve this problem, the invention proposes cooperation between the coordinators to determine non-interfering local time schedules whereby the coordinators rely on interference reports from the devices in the overlapping areas and apply a small number of simple rules. The proposed method is simple, scalable and independent from a central unit.Type: GrantFiled: March 5, 2019Date of Patent: April 23, 2024Assignee: SIGNIFY HOLDING B.V.Inventor: Andries Van Wageningen

Patent number: 11956648Abstract: The present invention relates to commissioning in the presence of multiple networks. A network node, which is expected to join a second network, joins a first network and enters a second state from a first state once it has joined the first network. Once it has received from the first network a message to leave it, it enters a third state from the second state. The network node entered the third state becomes responsive with respect to the first network and/or the second network by receiving a dedicated message to join network or is unresponsive with respect to the first network. Then, it enters the first state from the third state once the network node has received the dedicated message from a coordinator of the first network after closing the first network and/or from a coordinator of the second network, or upon expiry of a timer.Type: GrantFiled: June 18, 2019Date of Patent: April 9, 2024Assignee: SIGNIFY HOLDING B.V.Inventors: Zhi Zhong Zz Zhang, Dun Fa Df Chen, Hao Que
