Title: Chakavuth C. Chau and Cellular Network Timing Innovations.

Introduction

Chakavuth C. Chau is an inventor based in Garland, Texas, whose patent work focuses on timing systems for cellular networks. His inventions address how base stations generate and distribute precise timing signals. He is associated with Dish Wireless, L.L.C., and holds 2 patents.

Latest Patents

Chau’s latest patents concern edge-originated cellular network timing. The first, “Edge-originated cellular network timing,” describes a base station generating a grandmaster clock timing signal using information from a global navigation satellite system (GNSS) receiver and a local oscillator. The base station can send the signal to its distributed unit and distribute it over a network to other base stations.

The second patent, “Edge-originated cellular network timing for light base stations,” addresses networks in which a light base station serves as the timing grandmaster. The base station’s radio unit and router operate without an onsite distributed unit, while the distributed unit is hosted remotely at a local data center. A GNSS receiver and local oscillator support generation of the grandmaster timing signal, which can then be sent to the data center for use by the master base station and other light base stations.

Career Highlights

Chau’s patent portfolio reflects work on cellular infrastructure and network synchronization. The inventions describe approaches for maintaining and distributing timing across both conventional base stations and light base stations with remotely hosted distributed units.

Collaborations

Chau is associated with Dish Wireless, L.L.C. His patents describe systems involving base stations, routers, GNSS receivers, distributed units, and local data centers, illustrating the coordination required to provide timing across cellular networks.

Conclusion

Chakavuth C. Chau’s two patents focus on generating and distributing grandmaster timing signals for cellular networks, including deployments that use light base stations and remotely hosted distributed units.
