This article focuses on the additional features of the 802.11 wireless technology standard. The Block ACK is the simplest of the three features discussed in this article. Each data transfer is separated by a short interframe space period, further improving throughput of the wireless local area network. The Direct Link Protocol increases the efficiency of high-bandwidth applications by allowing two nodes to communicate directly rather than having to go through the access point. The Automatic Power Save Delivery addresses power issues for mobile technology devices that need to maximize battery life.
