6-GHz Development in the United States [Standards]
Edward S. Au · IEEE Vehicular Technology Magazine · 2019
Over the last 20 years, Wi-Fi evolved from a nascent technology to an integral component of the telecom infrastructure. For example, Wi-Fi delivers more than 50% of the world's Internet traffic and 70-80% of mobile offload [1]. However, there is a growing demand for Wi-Fi unsupported by spectrum capacity. Today in most countries, large contiguous channels that are required to support gigabit throughput are insufficient. For example, there are only five 80-MHz and two 160-MHz channels available in Europe, and many of the frequency bands in the 5-GHz band are constrained by the operation of dynamic frequency selection.
