Cut out Wi-Fi6 functions collect

Recently, nordic of enterprise of BLE chip bibcock released a chip of new 2.4GHz special Wi-Fi 6, the name is NRF7001, Face the market of content couplet net that has demand of low cost, low power comsumption.

Regard the head of BLE domain as the player, be contented client demand and fill market is blank, nordic develops group and property of relevant technology of Ensigma Wi-Fi IP at buying the Ensigma Wi-Fi of Imagination company 2020 first, back-to-back move announced to invest capital of research and development 2021 at Wi-Fi product, to 2022 Nordic rolls out Wi-Fi 6 of money of banner right-hand seat to cooperate with ICnRF7002, this product is OK with the company already SoC of blue tooth of series of some NRF52, NRF53 and SiP of net of couplet of content of NRF91 series beehive are used together.

This means NRF7001 is Nordic chip of the 2nd Wi-Fi, its action includes as complementary as NRF7002, domain of career of integral augment Nordic Wi-Fi.

But from the point of design parameter, no matter be NRF7002 or NRF7001, even if belongs to Wi-Fi 6 chip, the property performance of their both is far not as good as chip of smartphone domain Wi-Fi 6 can accomplish.

It is with NRF7002 exemple, its function feature is64Handling capacity of a bandwidth of QAM modulation, 20MHz, space shedding, 86Mbps PHY, this is far not as good as 8 bandwidth of the 1024QAM that Wi-Fi 6 can achieve, 160MHz, space shedding, 9.6Gbps carries style design on the head. But this kind of product can exist, because its itself faces intelligent household, asset to track,just be, can apparel wait for IoT market, not tall to transmitting the demand of speed, large handling capacity.

What have feature of industry of content couplet network more is, NRF7001 serves as the compensatory product of NRF7002, Former apply to 2.4GHz only, and latter support 2.4GHz and 5GHz Shuang Pin, the ability that this means NRF7001 to will back 5GHz aspect " cut down " dropped, because a lot of IoT application do not need to move in 5 GHz join,this also is, adjust for 2.4GHz sheet frequency band ability is helpful for reducing BOM cost further. On transmission rate, NRF7001 uses 64QAM support to offer the data rate that is as high as 69 Mbps, relatively the 86Mbps of NRF7002 wants again a few lower.

Of course, the superior performance of Wi-Fi6 is like low power comsumption (the target wakes up time TWT) , high security (WPA3) still have reservation, and NRF7001 also can be used at offerring 2.4 GHz Wi-Fi 6 to join together with SoC of blue tooth of NRF52840 low power comsumption.

Anyhow, chan Pin paragraph chip reflects the one share that gave function of complete Wi-Fi 6 only, but to application of net of couplet of content of the low speed in much, when deciding to whether embrace Wi-Fi 6, orThe most preferential look " low power comsumption, low cost, security " such ability, especially economy / it is more important that sexual price is compared, Be based on this to be enjoyed again Wi-Fi 6 and before the experience with acting different technique.

The general choice of domain of Wi-Fi 6 IoT

Besides Nordic, star appears on the market the company is become like happy Xin science and technology, Botongji, fly nimble science and technology, Silicon Labs is in at present face market of content couplet net to roll out Wi-Fi 6 chip, in light of the product parameter that announces from them:

The product takes the place of at the beginning of 1. each company all compositive blue tooth 5 reach above agreement, 2 syncretic become visible Wi-Fi, blue tooth already tide;

Acting product all is Wi-Fi 6 of 2.4GHz Chan Pin at the beginning of 2. each company. Besides the consideration that reduces cost, because the penetrability of 5GHz is inferior to 2.4GHz,Chan Pin of preferential development 2.4GHz is more, application of content couplet net is far to transmitting a distance have a preference more.

Of course, the product that the account that produces such general character is above company all is made to consume class market, emphasize sexual price comparing, did to a lot of parameter so reduce, also include to adopt the RISC-V plan with lower cost. But market of content couplet net also exists in high-end application, for example net of margin calculation box, couplet exceeding Qing Dynasty photographs terminal resembling a head, it is parameter setting likely right now on the level that can behave acme function, in this kind of setting, 2.4GHz/5GHz Shuang Pin can behave the ground of use force.

The technology is superfluous in industry of content couplet network it is common phenomenon, but also be born a new market

The market of content couplet net in the past, have occasionally appear " the technology is superfluous " phenomenon: Those who point to is a product the technical advantage such as the function in a certain respect, function, quality, exceed the value that the client is willing to pay for its far. Namely technical development direction and degree, did not use the resonance of directional in harmony of the product with the client.

Now the content couplet net of day, enterprise people can understand more, compare at period make brand-new, high-powered technology horizontal sky is born and overturn the market, more efficient development way still is to grasp hold " low power comsumption, low cost " train of thought, the care satisfies the most essential requirement, otherwise as good as at " cannon hits mosquito " , the client can not buy sheet for this.

So scan widely looks, market of content couplet net besides undertook adjustment when using Wi-Fi 6 technology, there also is a lot of precedent in other sphere, for example technology of net of couplet of content of 5G and 5G Redcap, 4G and Cat.1, tape is mixed in transmission distance make on transmission rate accept or reject evenly.

With nowadays newest 5G and 5G Redcap have give an example.

5G RedCap full name is 5G Reduced Capability, simplify the 5G system of ability namely.

Yao thinks 5G original conduct propaganda will promote network of couplet of equipment of network of large-scale content couplet, but in carrying out a process, industry discovery still has facility of net of couplet of a lot of content " with do not rise " or " do not need " 5G technology, for instance a lot of in setting of net of couplet of low speed content (can apparel sensor of equipment, industry, economy supervisory equipment) , the price of equipment itself is low, the demand that when they are mixed to bandwidth, delays is not high, but have demand to low power comsumption and low cost, and right now the cost with module resides 5G terminal chip not to fall high however.

Before such pain spot, because the target still is market of content couplet net, The design train of thought of 5G Redcap is to reduce cost, reduce power comsumption, reduce a system complex degree, draw close toward the balance of function and cost. The cost that Redcap calls terminal commonly on market relatively 5G terminal can reduce 60%-70% , redcap terminal projects power relatively 5G terminal reduces half above.

Nevertheless, 5G Redcap is based on 5G network compose to build from beginning to end, its are basic function can show a network via 5G as before flowing upgrade introduce.

Same, 4G Cat.1Also can be equivalent to the castrate edition of 4G, the leaves for lowermost version parameter user terminal level that industry says.

And from the point of development, cannot when oversight Cat.1 is rolled out comfortable meet 2G/3G removes a net, cat.1 industry got growing quickly, volume of modular group shipment predicts to will reach 200 million levels 2024; The development potential of 5G Redcap, the industry forecasts future to link volume level to be able to achieve billion.

The WiFi IoT technology that alludes the earliest as to the article, consideration WiFi standard is updated net of apt content couplet, and what WiFi holds proportion in join of content couplet net, the potential that we need not underestimate our to develop for a long time...

To be opposite each element undertake industry of network of Wi-Fi content couplet analyse and be judged, banner of content couplet medium issues academy of AIoT star chart to be being begun closely" industry of network of couplet of Chinese Wi-Fi content considers to report (2023) "survey and contribute the job. Serve as what already released " industry of network of couplet of content of Chinese blue tooth considers to report (2023) " sister piece, a report general once more the content such as trend of player of focusing WiFi technology and product, market, industry, industry, the individual that special reception has intent to participate in content to build or enterprise and we communicate collaboration.
