当最后5 GHz乐队于2003年开放时，它预示着一个新的连接时代的曙光，在该时代中，启用Wi-Fi的设备将被编织成世界各地的生活中。快进17年和4月23日FCC决定在美国发布1.2 GHz的无执照的频谱为Wi-Fi，看上去将使我们进入Wi-Fi Revolution的下一阶段。
Plans to open this spectrum from approximately 5.9 GHz to 7.1 GHz will undoubtably allow the US to edge ahead in its Wi-Fi mission and could have a significant impact on other regions as a result. While the European CEPT (Conference of Postal and Telecommunications Administrations) has been working hard to ensure that the region is on track to release 500 MHz of 6 GHz spectrum in the near future, Europe will need to keep a close eye on the action across the Atlantic. Failing to eventually follow suit in offering a more complete spectrum could leave the continent lagging behind and unable to deliver on both its Wi-Fi promises and objective to realize a千兆社会。
在这种背景下，这就是为什么其他频谱是维持Wi-Fi增长所需的重要元素的原因。
交付Wi-Fi Gigabit Band Promise
甚至在当前的大流行将我们全部寄给我们之前，Wi-Fi的互联网流量比任何其他无线技术都多。不幸的是，所有这些需求的压力开始显示出来，尤其是在公寓楼，机场和体育场等高密度移动环境中。随着5G的推出，物联网设备的扩散以及Wi-Fi依赖服务的爆炸，将越来越多的设备驱动到有限量的无载频谱上，它迫使该技术做出不可持续的折衷方案，以便与与之共处的折衷方案这么多用户。
Aside from causing performance issues today, the congestion of the unlicensed spectrum also has bigger implications in terms of the industry’s promise to deliver the type of multi-gigabit services that are in increasing demand – making it difficult to enable the 80 MHz or 160 MHz channels these services require.
通过提供额外的许可光谱，将提供更广泛的渠道。Opening 6 GHz to Wi-Fi will accommodate 14 additional 80 MHz channels and seven additional 160 MHz channels – all of which are needed to accommodate today’s growing number of high-bandwidth applications and their need for faster data throughput, such as high-definition video streaming and virtual reality. Europe is currently looking to add six additional 80MHz channels and three 160 MHz channels.
简而言之，我们需要额外的无执照的频谱来实现今天和将来的Wi-Fi承诺。
Driving the Wi-Fi 6 Revolution
去年下半年批准Wi-Fi 6（802.11ax）预计将在未来三年成为事实上的Wi-Fi标准。在欧洲，IDC estimatesWi-Fi 6市场将从2019年的6175万美元增长到2024年的16亿美元。其他未许可的频谱将是支持这一下一代Wi-Fi不可或缺的一部分，而Wi-Fi已经在5 GHz乐队的有限容量中挣扎。
然而,wi - fi的全部优势6只be realized when Wi-Fi 6 equipment does not have to work around other radio standards. With enough spectrum to safely deploy wider channels and green-field deployments alleviating concerns of backwards capability, the 6 GHz band will essentially become a VIP-only area for Wi-Fi 6 users. This additional airspace, uncrowded by legacy devices, will allow enterprises to lean on Wi-Fi more heavily than in the past for use cases within manufacturing, logistics, and critical communications, to name a few. Industrial environments are also expected to see strong adoption of Wi-Fi 6E to deliver applications including machine analytics, remote maintenance, or virtual employee training. Wi-Fi 6E is the name of a new extension to the existing Wi-Fi 6 standard to signify it's capable of supporting all-new 6 GHz frequencies. The 6 GHz spectrum will unlock the full potential of Wi-Fi 6, and become key to driving its adoption.
展望未来
随着美国为Wi-Fi发布6 GHz频谱，它不仅可以期待解决当前的拥塞和带宽问题，而且还可以释放Wi-Fi的未来未来收益6.欧洲必须注意并继续努力以释放我们自己的频谱并最终确定了500 MHz在5.9-6.4 GHz频段中急需的未经许可频谱的分配。
欧洲企业的成功取决于无线基础设施，使他们能够与U..S中的同行竞争，伦敦，巴黎和罗马的消费者应与纽约市的消费者相同的高速无线体验享受相同的高速无线体验，达拉斯或洛杉矶。
