Abstract
A multi-mode access point (AP) and a method of controlling access between that AP and one or more clients is disclosed. In a first time period, the AP commands the client(s) not to send data on a first channel, using, for example, the 802.11a Wireless Local Area Network (WLAN) Standard. The AP is enabled, in that first time period, to receive data on a second channel using say, the 802.11b WLAN standard. At the end of the first time period, the AP switches so that the first channel is commanded to be silent while data can instead be sent via the second channel. Data queuing for a given channel can take place at the or each client when that channel is commanded to be silent, for subsequent transmission when that channel is enabled again.
