在Wi-Fi 6产品开始普及到千家万户的时候,Wi-Fi 7也终于崭露头角了。

When Wi-Fi 6 products began to spread to thousands of households, Wi-Fi 7 finally emerged.

On the morning of April 7th, H3C, a subsidiary of Tsinghua Unigroup, announced that the world’s first enterprise-level smart native Wi-Fi 7 AP new products, WA7638 and WA7338, were first released by Chinese enterprises after the first Wi-Fi 6 AP in August 2017.

It is understood that Wi-Fi 7 (802.11be) supports three frequency bands of 2.4GHz, 5GHz and 6GHz, the bandwidth is 320MHz, 4096QAM modulation is introduced, 16×16 MU-MIMO, the maximum rate can reach 46.08Gbps, the delay is within 5ms, compared with Wi-Fi -Fi 6 10-20ms latency reduced by 100%.

Back to H3C’s Wi-Fi 7 AP this time, the official introduction supports tri-band 12 streams and tri-band 10 streams, and the transmission rate can reach up to 18.44Gbps. Among them, the limit rate of a single terminal reaches 11.53Gbps, which is 2.4 times higher than that of Wi-Fi 6.

For example, under the 80Mb/s bit stream, the download time of 72GB 8K video is less than 1 minute.

In other respects, the latency is less than 5ms, high concurrency of 400+ can be achieved, and the number of concurrency of a single AP is increased by 2 times.

It is worth mentioning that in March, Qualcomm also released the world’s first Wi-Fi 7 wireless integrated chip FastConnect 7800, with tri-band, peak transmission speed of 5.8Gbps, and a delay of less than 2ms. It will be commercialized in the second half of the year.

4月7日上午消息,紫光旗下新华三宣布,全球首发企业级智原生Wi-Fi 7 AP新品WA7638和WA7338,这是继2017年8月首发Wi-Fi 6 AP后,中国企业的再次领跑。

据了解,Wi-Fi 7(802.11be)支持2.4GHz、5GHz、6GHz三大频段,频宽320MHz,引入4096QAM调制,16×16 MU-MIMO,最大速率可达46.08Gbps,时延5ms内,相比Wi-Fi 6 10-20ms的时延降低100%。

回到新华三此次的Wi-Fi 7 AP上,官方介绍支持三频12流和三频10流,传输速率最高可达18.44Gbps。其中单终端极限速率达到11.53Gbps,较Wi-Fi 6提升2.4倍。

官方举例,在80Mb/s码流下,72GB大小的8K视频,下载时间不到1分钟。

其它方面,时延低于5ms,可实现400+高并发,单AP并发数提高2倍。

值得一提的是,此前在3月份,高通也全球首发了Wi-Fi 7无线集成芯片FastConnect 7800,三频,峰值传输速度5.8Gbps,时延不到2ms,下半年商用。
