我很高兴能有一个历史的前排座位。FCC正在采取步骤allocate more spectrum for Wi-Fiin the 6 GHz band. It has been over 15 years since the last 5 GHz band was opened in 2003, and nearly 35 years since the FCC created the Part 15 rules that opened the 2.4 GHz and 5.7 GHz bands for use by unlicensed Industrial, Scientific & Medical (ISM) equipment. This decision was one of the most successful regulatory experiments in history, and led directly to Wi-Fi enabled devices being woven into the very fabric of the lives of people all around the world. The Wi-Fi industry is now shipping over 3 billion chipsets every year, and the global installed base is forecast to exceed 15 billion – or twice the entire population of the Earth – by 2022.
作为消费者，我们认为Wi-Fi依赖于理所当然的范围。但是，有限的无执照频谱越来越拥挤，并且不足以容纳更宽的80 MHz和160 MHz频道来提供多Gigabit服务。现在需要更多。频谱不是免费的，并且在大约2 GHz和7 GHz之间的“中间频段”中的频率是Wi-Fi的理想选择，已经分配了几次。这意味着要确定其他无执照的服务可以与现有现有企业的“底漆”安全地共存的艰苦努力，然后倡导现有的频谱持有人和政府。幸运的是，Wi-Fi拥有20多年的经验，与他人共存，并使不良的频谱可用。
Why Do We Need More Spectrum?
简单而简单，我们需要其他无执照的频谱才能继续提供Wi-Fi品牌承诺。
wi - fi的压力开始显现,尤其。公众y in high-density mobile environments like apartment buildings, airports and stadiums. Wi-Fi is used to carry well over 70% of data traffic originating on cellular-capable mobile devices. Wi-Fi consumption is further driven by the rollout of 5G, the proliferation of IoT devices, and the explosion of Wi-Fi dependent services.
Another phenomenon is occurring: broadband connections to homes and enterprises are quickly becoming faster than Wi-Fi interfaces. With choices ranging from high-speed broadband to metro Ethernet, WAN speeds have come a long way from the T1 days. Wi-Fi needs to keep up to ensure that the airlink is at least as fast as the WAN connection.
Why 6 GHz?
The 6 GHz band sits next to the 5 GHz band that Wi-Fi has been using, but it’s far more than that. The Wi-Fi industry has been working with the key constituencies to understand and overcome both technical and political issues. Spectrum is allocated at a global level by the ITU and governed by treaty relationships.
6 GHz无线电LAN（RLAN）无法干扰用于固定微波炉，卫星数字无线电，电信回程，公用事业，公共安全，铁路或电子新闻媒体的频谱。重要的是要协调乐队在全球范围内简化设计和部署。正在研究6 GHz的渠道计划草案，主要目标是确保我们可以有效地使用更广泛的渠道 - 与今天不同。
在现有人士担心对电视卡车以及警察直升机广播的移动乐队有害干扰。为了确定现实世界中的6 GHz Wi-Fi Interfere如何由11家领先公司组成的联盟，包括Hewlett Packard Enterprise，Broadcom，Apple，Microsoft，Facebook，Google，Google，Intel和Qualcomm，对固定卫星进行了深入研究service that’s used for geostationary satellites. We undertook a similar study for terrestrial microwave services, and adapted our rules to protect these crucial services. That study was delivered to the FCC in January 2018, and helped lead to the FCC’s decision to open a Notice of Proposed Rulemaking (NPRM) to open the 6 GHz band to unlicensed use which is underway now.
Wi-Fi行业提出了三个不同类别的访问点，具有不同的规则，可在乐队的不同部分进行优化。这些可以可视化为：
较低的室内6 GHz设备不会对现有的6 GHz任职者构成任何干扰的风险，后者仅在户外，大多在较高的海拔高度上。对于更高的功率或室外设备，将使用Wi-Fi行业提出的新自动化频率协调（AFC）方法来避免有害干扰。目前，建立一个新的6 GHz点对点链接需要与在收音机前面的“钥匙孔”形状地理区域中运行的现有许可证持有人进行仔细的协调。AFC系统采用了此概念并将其自动化，以便它可以扩展到Wi-Fi生态系统的规模，从而利用FCC的通用许可系统（ULS）作为地面真相，因为所有现有的被许可人都需要注册其系统。
What’s the Timeline?
It takes an average of nine years to open up a new frequency band for use by a new service. As an industry, we began working with the FCC in 2017 and we’re hoping to have the first 6 GHz in the US available in about two years from this writing, in time for 802.11ax Wave 2 equipment.
Aruba is pleased that the FCC unanimously voted to move forward on the提议的规则制定中型频谱的通知。我们欢迎FCC主席Ajit Pai在12月的声明中“”6 GHz乐队可以帮助推动下一代Wi-Fi，我很乐观，我们将能够在2019年提供无牌使用。”在欧洲，正在进行6 GHz的技术研究in response to a mandate from the European Commission. From a European perspective, we’re hoping for a final ruling by 2021. Meanwhile, both the IEEE and 3GPP have begun standards work to support 6 GHz. The latest 802.11ax Draft 4.0 includes a variety of 6 GHz related features.
