A few years ago, at the china-developer's congress 2023, china put out a one-time move to hold on to these years。
A multipurpose and specialized ai large model, a harmo that removes android codeNyos next, the standard for assessing the experience of application of folding screens/plating, which provides suitable direction for folding screen applications。
But apart from these things, which are closer to our ordinary users, which are easy to tell, china has announced a black technology that may not have come to your attention:
Starfleet, a communication standard that integrates "stabler wifi" and "better bluetooth"。
According to the official introduction, starfleet and harmo..Like nyos, the main hit is "all things connected"。
It also provides for two agreements:
One is some kind of wifi-like slb, except that it's lower than wifi, more stable in the network
There's another one that looks like bluetooth, but whether it's speed, delay or signal, it's the traditional bluetooth。
But in tony's opinion, it canTechnologyIt doesn't matter how much more than wifi and bluetooth。
"integration" is the most important aspect of the current chaotic wireless interconnection。
Small partners, who often need to be connected with wireless devices, know how fragmented and experienced the current wireless interconnectivity is。
Wireless mouse, wireless headphone receivers are loaded on computers; however, if the receiver is replaced by bluetooth mouse and headphones, the poor performance is largely inoperable。
The connection between mobile phones and motors is also true, although theoretically there is no problem with the connection; in practice, unless mobile phones and car brands match in both directions, it is necessary to return to the age of bluetooths playing the total loss of sound。
For those of us who often use a pile of equipment at the same time, the interconnectivity and cross-fertilization of cell phones is even more disturbing。
Cross-producer documents are relatively well shared and can barely be divided into four camps: the chinese-led inter-communication alliance, the other domestic manufacturers' inter-communication alliance, the nearby share, and airdrop。
Within the camp, equipment is barely available as long as it is not routinely searched and the transmissions fail from time to time。
The country's largest cross-fertilization alliance
The connection is completely different。
The interconnective ecology of the manufacturer is limited to the interior, and the ovs each have a set of clipboards that they want to share with the tablet of the vivo, which is more difficult than going to the sky。
Each family's system is completely torn apart, and if there's no “family bucket”, don't mention convenient cross-equipment。
Although this is the case now, there must be a manufacturer's own little 99 in it。
But after a lot of bad experiences, tony has also discovered two technical problems, which may be the reason why the manufacturer cannot comply even if it wants to。
The most important of these is the absence of standards。
In wifi and bluetooth collaboration, there's not a single force that can hold the factory's head。
In terms of characteristics, bluetooth and wifi were supposed to be complementary, and if they could work together, it would be better:
Wifi is fast, has a long distance to connect and is more stable, but hardware is complex, more efficient and complex when connected
Bluetooth, while saying that the distance, speed and quality of communication are tragic, saves electricity, light quantification and simple connectivity, just to fill the blind zone of wifi。
Unfortunately, however, the technical standards of wifi and bluetooth are fully divided into two alliances, which were designed without any consideration of synergetic operations, let alone synergies。
The fragmentation of documents is a vivid example。
In theory, cross-fertilization is a simple thing: two mobile phones are easily identified through bluetooth, and then tell each other a temporary wifi hotspot and password, and then quickly transmit files via the hotspot。
But the question is, the wifi alliance and the bluetooth alliance have no rules at all, and each of these steps, which specific programmes should be adopted! Because there's never been so much cooperation between the technology unions
So company a sets the scheme a, company b designs the scheme b, company c makes the scheme c。
And you can't yell at it because there's no standard in the industry。
The other problem is that bluetooth was designed too low, and now, in 2023, it can't do anything。
But wifi's lower limit is too high, and the equipment that wants to get out of the pit of bluetooth tends to hit the “wifi lower limit”, an unbreakable barrier。
A chestnut, now the most common demand — a wireless headphone — is a victim who happens to be stuck in the middle of two technologies and who does not have enough。
The continuation of wireless headphones is important, so blue teeth that save electricity appear to be the most appropriate
But as long as those who have studied the bluetooth sound know, now the bluetooth headset is barely working, it's entirely the result of a bunch of slutty operations in the bottom of the bluetooth。
For example, lower the delayed aptx ll and improve the ldac。
Without these private agreements, the delays in the bluetooth headset, the sound quality and the quality of connections are entirely tragic。
You can go up to zero seconds of audio delay, listen to mp3 at most, and have poor signals in the crowd。
Every single point here is beyond the reach of current bluetooth technology。
So, using wifi's wireless ear is a good idea
As long as they are searched for treasures, they are found to be out of the regular market。
After all, wifi headphones are bound to face higher costs, complex-to-explosive connection operations, non-standard software, and higher utility。
No one would do that。
Similar to wireless headphones, there are now a lot of wireless devices, such as keyboards, car interconnections, mostly caught in the middle by the huge gap between bluetooth and wifi。
Bluetooth is only barely usable, and the cost of changing to wifi is too high, and it can only be cleared through various private hardware and private agreements。
In tony's view, the twinkle is a sword to both of these ends and an attempt to create a uniform and workable interconnectivity norm。
First, in response to the issue of cross-technical collaboration between the "low-end bluetooth" and "high-end wifi", the starflake alliance adopted an approach that could be described as a miracle:
Turn both "wifi" and "bluetooth" into "star flash"。
As mentioned at the beginning, stars can be divided into two branches: slb and sle。
In terms of their characteristics, slb is the "stabler wifi," fast, but complex
And sle is "better bluetooth," slow, but simple, low effort。
But these two branches are not as irrelevant as wifi and bluetooth, but they are two different uses under the same standard。
In coordinating the "star wifi" and "star bluetooth," the star flash alliance will certainly not have a history of each other fighting, relying entirely on the manufacturers themselves。
Sle and slb share a top-level design
What's the use of it
For example, it provides the foundation for future interconnectivity between a unified car and a mobile phone。
As with the fragmentation of mobile phone traffic, a considerable part of the confusion in the interconnectivity is purely technical。
Since the nature of bluetooth meets the need for interconnectivity, wifi's connection and authentication process is too cumbersome, the most common method of interconnection is also the pre-bluetooth authentication, automatic exchange of wifi's connection parameters, and eventually automatic switching to wifi to complete the interconnection。
However, as stated earlier, the two technical organizations behind wifi and bluetooth did not go into this depth of cooperation, and the process was defined entirely at the discretion of the manufacturer。
It's a completely different set of interconnective technologies, which naturally cannot be compatible。
Now starfleet unites “wifi” and “bluetooth” within a framework that certainly does not completely prevent the manufacturer from intentionally incompatible, but offers at least one technically feasible and advanced compatibility standard。
And the historical burden on bluetooth is too heavy and its performance too bad, and it's already a bit out of date, and the starlight gives the answer to the question of "rich and skilled, is willful":
Drop the historical burden of bluetooth and rewrite the "star bluetooth"。
First of all, can't bluetooth speed
Starfleet sle, bluetooth, six times the speed of the ble
Undamaged uncompressed audio, up to and including 4 mbps, fully meets demand at the highest speed of sle 12 mbps。
And then bluetooth's too late
That's because bluetooth protocol is too old to send up to 133 data per second, with a theoretical delay limit of 7. 5 milliseconds
Sle is designed to optimize the delay by sending up to 4000 data per second, with a theoretical delay limit of 0. 25 micros
And the difference between that is probably an underground one。
Bluetooth mouse has the highest return of 125 hz, and even the office code word makes tony uncomfortable。
The mouse with the sle maximum yield of 4000 hz, in terms of return alone, fully reaches the game mouse。
After all, the well-known open-wire game mouse g304 returns less than 1000 hz。
If you want a more image analogy, imagine a delayed difference between the 30hz monitor and the 900 hz monitor (currently not available)。
And finally, bluetooth's connection is bad
Starfleet sle directly uses china's well-known polar code coding program on 5g, while at the same time using china's technology accumulated over the years in the field of communications。
There are occasional doubts about china's bragging, but generally there is no doubt about the good signals。
Such a combination of punches could be said to have provided the manufacturer with a technical route out of private agreements, providing a common basis for agreement across platforms and across manufacturers。
Now there's only one last question: will the manufacturer with a small idea play with wah
At least for the time being, it should。
Even if we don't look at the 300-plus members, just look at the names of the members of the starfleet league, tony can be sure that the stars won't be invisible。
Wally ov, move, zing, ucd, violet。
To be honest, it's been a long time since we've seen an alliance so high that we can get the whole industry chain。
And finally, there's a lot of "obligation" about stars, but they all have to go deep into technology, not exactly in line with our "sleeping books" and "getting up news." for example, the ceo, which is a voice research unit for starlight members, tells us that the ultimate goal of starlight is to replace cable in part of the scene。
Now, the greatest advantage of wire over wireless is not speed, but delay. Don't look at tony's "stabler wifi" and "better bluetooth" to describe the flashes. In fact, its whole set of techniques and wifi, bluetooth have nothing to do with it. From a technical source alone, the stars should be called "personal 5g"。
It inherits the character of 5g's "extra-low delay" even better than 5g's, drying the delay directly to near-lined microseconds。
It's hundreds of times higher than millisecond wifi! But it's because it's too much like 5g, it's too high, and it's a little bit difficult for the stars to develop:
Star flash chips are too expensive! Especially the high-compatible version of the slb like wifi in the starlight, which is said to be slightly more expensive than expected. So, for the time being, starfleet is simply planning to achieve the replacement of cable on less sensitive vehicles。
However, as a low-matching agreement in the stars, sle, the cost is probably acceptable, and it may be seen on the market next year. Sle module
Finally, it is also a tip-off: it may be the result of an emergency project after china was sanctioned。
Seeing the date of the stars, it does。
In other words, after the sanctions were imposed in about 2019, china took a better set of wifi+ bluetooths directly from the top, and resolved the split between the two modes of connection。
Four or five years ago, a project like starfleet, with an emergency uplift, had been carried out by china。
According to technology development patterns, those “black technology” projects, these years should be exactly the time of the outbreak。
There's been a tip-off before that, saying wigand might re-launch their 5g flagship in the near future。
If this news is true, it might be able to draw a lot of technology from behind。
