Abstract: A cloud-based Wi-Fi network architecture consisting of a CU and RAUs is proposed as an improvement on the conventional Wi-Fi architecture with traditional access points (APs). In addition, a method for uplink data transmission in a cloud-based Wi-Fi network is proposed. In a conventional Wi-Fi network with independently operating APs, APs close to each other may not be able to utilize the same frequency band efficiently because of significant amounts of interference. However, in a cloud-based Wi-Fi network, 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. For each frequency band, the proposed system utilizes a diversity combining that combines multiple signals and introduces a single improved signal with high signal-to-noise ratio for uplink transmission in the cloud-based Wi-Fi network.
