5G+4K: This is how you can spend Valentine's Day this year

A sudden epidemic has plunged the whole country into a haze. For our own health and to help the country win the battle against the epidemic, this Spring Festival, we have chosen to stay at home and lie in bed.

But for couples, this is undoubtedly torture. From the beginning of the holiday to the postponement of work resumption to remote work, I believe many couples have not seen each other for half a month. Especially for couples in the passionate love period, this is undoubtedly like a year.

The annual Valentine's Day is coming again, but judging from the current epidemic situation, it is still difficult to go out and date to spend this holiday together. So, are there other ways to help couples realize long-distance Valentine's Day dates?

The answer is of course yes. I believe everyone’s first reaction is “You can use WeChat video”! Indeed, WeChat video is currently the most convenient and most commonly used video method, but I believe all couples have encountered such situations: for example, there will be a freeze when you just open the video; there will often be interruptions and audio and video out of sync during the video; due to the resolution of the mobile phone or computer lens, the visual experience during the video is too different from a real date, etc.

It has to be said that in the 4G era a few years ago, although such a video experience made couples distressed, they were limited by the network technology at the time and had to use it even if they wanted to complain, because not using it meant they couldn't even see the other person's "mosaic" face.

With the Ministry of Industry and Information Technology officially issuing 5G commercial licenses to China Telecom, China Mobile, China Unicom, and China Broadcasting Corporation on June 6 last year, such bad video experiences between couples will be gone forever. Because 5G is here.

For lovers, the arrival of 5G means that video calls between the two parties no longer have to endure the troubles of lag, unclear voices, and out-of-sync audio and video. This is due to the ultra-high transmission rate and ultra-low latency of 5G: the theoretical transmission speed of 5G can reach 10Gb/s. So, what does this data mean? In terms of image, the theoretical transmission speed of 5G is 10 times faster than the home gigabit network, and how much faster than the 4G network we have been using? 100 times. On the other hand, in terms of latency, the 1ms latency of 5G is dozens of times lower than the tens of ms of 4G.

Of course, for couples, compared with these 5G technologies, they care more about how to use 5G in video dating with their significant other. The answer is also very simple, it requires two things: one is a 5G mobile phone, and the other is that 5G base stations have been deployed in the area. As for 5G, as of now, except for Apple, all major mobile phone manufacturers have released 5G mobile phones, and a 5G mobile phone can be purchased for as low as 2,000 yuan, so this is not difficult.

Another factor is whether 5G base stations are deployed in the area. Since 5G is only eight months away from commercial use, 5G base stations are still in the initial stage of deployment nationwide, and 5G base stations are mostly in first-tier cities, provincial capitals and other economically developed areas. Therefore, as long as these two points are met, couples affected by the epidemic can have a good video date experience on Valentine's Day this year.

Of course, this is also the initial stage of celebrating Valentine's Day through video this year. If you want to make this Valentine's Day more realistic, you can add a 4K video. Compared with the commonly used 1080p HD video, the display effect of 4K video is more realistic and delicate, so lovers can see each other better.

Previously, although most flagship mobile phones supported 4K video recording, it was difficult to watch 4K videos online due to the limitation of 4G transmission speed. This is because watching 4K videos requires a transmission rate of 40-60Mb/s, while the transmission speed of 4G is usually 8-60Mb/s, which is simply not enough.

5G can meet the needs of online viewing of 4K videos even at a low rate of 100Mb/s. Therefore, thanks to the 5G network, 4K video will also develop rapidly. For example, last year, 5G+4K technology was used for live broadcasts of many large-scale events.

In addition to 5G+4K, if couples want to date each other due to geographical distance, there is another way: VR. However, in my opinion, although this technology is more realistic and three-dimensional, VR is not mature enough at present and there is still a certain threshold for large-scale consumer use.
