Objective of the new approach is to improve frames. legacy network capacity in such home scenarios. Network capacity is increased by allowing setting up multiple contemporary IEEE 802.11 connections using a single WLAN card. All connections share the same la lb data link and physical layers but use different b XX channels; the MAC is responsible to handle the S S channel switching as well as to allocate/de-allocate the QSTAI QSTA2 direct link sessions. In particular we aim implementing a solution where stations can be associated to an Figure 1.
