Patents by Inventor George Gang Chen

George Gang Chen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11962370
    Abstract: A technique for improving wireless communication characteristics involving matching transmitter antenna patterns to receiver antenna patterns. In a specific implementation, the transmitter antenna pattern adapts to changing parameters, such as when a smartphone is initially held in a first orientation and is later held in a second orientation. Because the transmitter antenna pattern matches receiver antenna patterns, signal quality between stations improves. In some implementations, antennas are organized and mounted to maximize spatial diversity to cause peak gains in different directions.

  • Patent number: 11706841
    Abstract: A plug-in network device is disclosed. The plug-in network device can be used in association with a network management system and an infrastructure network device. The plug-in network device includes two antenna arrays, one of which is up-facing and one of which is front-facing. The plug-in network device can achieve wireless communication with the infrastructure network device via the up-facing antenna array and provide network services to wireless stations through the front-facing antenna array. The network management system can manage both the infrastructure network device and the plug-in network device.
