IP3 2023 – Network & Cloud (LOT 14932)

This lot discloses a cloud-based Wi-Fi network architecture consisting of a Central Unit (CU) and Remote Access Units (RAUs) to improve on the conventional Wi-Fi architecture with traditional Access Points (APs). It uses a method to uplink data transmission in a cloud-based Wi-Fi network where the CU coordinates RAUs so that they can operate in the same frequency band by transmitting or receiving signals through the shared wireless medium to improve spectral efficiency. Most operations for providing data services, including baseband signal processing or wireless Medium Access Control (MAC), are performed at the CU in the cloud, making service maintenance and updating new communication protocols of a cloud-based network easier.
