Abstract

WiFi is every where now. In many places such as: home, office and public areas, the user could easily access the network, surf the internet, view the online video clips, and download big data through WiFi. However, in current WiFi infrastructure, the devices within the vicinity have to share the channel in a time sharing fashion. Thus the network throughput decreases linearly with the number of active devices. With more and more applications going through wireless, how to get the higher throughput in these dense area, become a hot research topic in the WiFi area. To solve this throughput challenge in dense area, research institute and IT worked together and proposed one WiFi management protocol. The main idea of this new protocol is to increase the throughput via higher spatial reuse. In the new protocol, the devices will reserve the normal space area through the handshake package (RTS/CTS), same as the legacy protocol. But after the initial device reserves the channel, it will reduce its data transmission power to decrease the wireless signal interference, and meanwhile invite the nearby devices to join the transmission. So the participant devices would reuse the channel/space which the initial device reserves, and more devices could transmit the data at the same time. We implemented and enable this WiFi management protocol on wireless card. And in the field trial with 6 laptops (3 pairs transmitting data at the same time), the new protocol got above 80% throughout increase comparing to the legacy WiFi protocol. And the benefit will be increased linearly with the number of the participant devices in the environment. This new WiFi management protocol will help increase the overall throughput in dense area dramatically, and it will also enable our IT to deploy the throughput-demanding applications, like wireless docking, in the company.
