Snapdragon 855: 802.11ax-Prepared / Wi-Fi 6 Demonstrations

Whereas the headline options of the brand new Snapdragon 855 Cell Platform could also be its 5G connectivity or the Cat 24 LTE modem or the brand new CPU / GPU mixture, the truth that that is the case is the S855 Chip can be 802.11ax-capable. Below the brand new branding that is "Wi-Fi 6". Qualcomm had a demo to showcase it on the Qualcomm Snapdragon Summit.

All In For Wi-Fi 6, the brand new title for 802.11ax

With out the necessity for an additional chip, the brand new Snapdragon 855 SoC permits the next-generation flags to be 802.11ax-enabled. That is the replace to the favored 802.11ac commonplace, which allows greater throughput on related . One key level that 802.11ax can acquire is overcrowded networks: when a number of units require important bandwidth, akin to 4K / 8K video, the brand new SoC helps eight spatial streams concurrently, giving higher ends in these congested community conditions achieved.

The demo Qualcomm had at hand was easy – an eight-antenna 802.11ax entry level for 3 802.11ax units and three 802.11ac units, every offering a type of variable-bit-rate video streaming match the obtainable entry level machine bandwidth. On this congested community, the 802.11ax units had greater bit charges, leading to greater high quality and fewer picture loss.

The router used was an inner Qualcomm design that was not provided on the market. It was fascinating that he had an SFP + connection from the cupboard to the router to offer the information. This most likely signifies that even with a number of units that require quite a lot of bandwidth, the information supply spine will nonetheless be enough to assist them.

We must always level out right here that the Snapdragon 855 SoC is 802.11ax-ready, which differs from the whole compatibility with 802.11ax. The requirements are within the ultimate levels of ratification. Nevertheless, Qualcomm needed to cease improvement at one level to convey it to market in a well timed method. Due to this fact, the 855 SoC helps a subset of the 802.11ax commonplace and most certainly not the total commonplace as it will likely be.

This isn’t an issue for many issues, and a few of our common readers will bear in mind after we launched "802.11ac-ready" or "802.11n-ready" routers and units earlier than they did Requirements have been full. However, it will likely be fascinating to see which smartphone producers listing 802.11ax assist or 802.11ax-ready assist.

For these confused with 802 numbering, the Wi-Fi Requirements Alliance has not too long ago renamed all the things to simplify it. Right here is the conversion desk:

Wi-Fi title and efficiency

Prime efficiency

New title

Wi-Fi four
150 Mbps
300 Mbps
450 Mbps

Wi-Fi 5
802.11ac (80 MHz)
433 Mbps
867 Mbps
1.27 Gbps

802.11ac (160 MHz)
867 Mbps
1.69 Gbps
2.54 Gbps

Wi-Fi 6
867 Mbps
1.69 Gbps
2.54 Gbps

Added to the combination is ​​that 802.11ay, which is the 60 GHz community that additionally helps the S855 (an extra chip is required), has no quantity, however is known as Wi-Gig.
