Communications using wireless networks nowadays receives an increasing amount of users and devices. This implies in an increasing need for improvements in wireless networks. IEEE 802.11ac standard enables channels wider than 20 MHz bandwidth. But currently, access points allocate channel bandwidth statically, independent of the clients’ configurations. This leads to poor network performance. In this work, we design a system that enables clients to choose the link’s bandwidth they connect to the APs. We validate the system through realistic experiments. We show the trade-off between latency and throughput. Our results show that our system improves the frequency spectrum usage, and provide better throughput/latency for the user.
