Breaking the Gigabit-per-second barrier with 802.11AC

Summary form only given. The 802.11ac standard will push wireless LAN throughputs over the gigabit-per-second barrier in the coming years. Rather than only improving single link throughput by using more bandwidth and 256 QAM, 802.11ac also improves network throughput by adding MU MIMO capability. MU-MIMO makes it possible to achieve large throughputs cost effectively by having relatively simple client devices with just one or two antennas that can be simultaneously transmitted to by an access point that may have up to eight antennas.

Introduction to Globalization of Mobile and Wireless Communications: Today and in 2020

Mobile communication has expanded the basic need for humans to communicate to “from anywhere at any time,” which was unthinkable only 25 years ago. It has touched almost every person, rich or poor, child or adult, around the globe. Increasingly, new developments in wireless data and mobile internet are augmenting the voice communication experience with much richer multimedia content consisting of text, video, and images. In not too distant a future, wireless data connectivity between the machines and sensors is destined to reshape the environment we live in and impact our lives in ways that we can hardly imagine. The emerging economies are already skipping legacy technologies, going for the next generation, and will be the hotbed of some of the innovations that would find their way to the affluent economies.
