ã€World Wide Web Reporter Zhang Zhiying】 The gunfire has not sounded, and some operators have been unable to stop running. Technology foreign media MUO pointed out on the 3rd that some operators recently spoke blatant lies and claimed that they started to provide 5G services. However, the 5G service is actually a faster and better network version. It is still based on the current 4G LTE technology. These false advertisements are so rampant that the United Nations has to be involved in management.
For each "G", the industry, including manufacturers, operators, etc. must agree to a set of standards. The agency that defines these standards is the International Telecommunication Union (ITU), an agency affiliated with the United Nations. Recently, it finally introduced a set of standards that proved that advertising on "5G" is actually false.
AT&T's 5G does not meet these standards, and Verizon's upcoming 5G service is also not compliant. They are using 4G 4x4 MIMO to increase the speed of data, not true 5G. Data speed is important, but 5G is not just data speed, there are a lot of conditions. So let's take a look at what criteria 5G has, and it will not be deceived by marketing practices.
What is 5G?
Now that 5G has not been defined accurately, no one knows what the final standard will be. However, the ITU has so far reached agreement on several key requirements for 5G performance.
First, call uninterrupted line: This is the biggest change for the average mobile user, when the mobile phone switches the base station between 5G networks, the mobile phone will not cut off or lose the network connection. ITU stated that 5G networks do not have call interruptions and interference, so unless they meet this specification, they are not 5G.
Second, low delay: 5G mobile phones will have a delay between 4ms to 1ms (the lower the better). The delay is in milliseconds, which is the amount of time your phone sends a signal to the internet server. The fastest of 4G is a delay of 50ms. Low latency will greatly improve the experience like the augmented reality.
Battery efficiency: You also know how data connections drain your phone's battery. The 5G network will significantly reduce power consumption. Through the "sleep" function, the mobile phone does not need to use the network at all times.
Fourth, can operate at a speed of 500 kilometers per hour: With the speed of transportation, your mobile phone speed is also intensified. This means that your mobile phone is rapidly changing the mobile base station. Current mobile networks cannot handle fast handovers between these base stations. However, with 5G, even if you are on a high-speed train, the speed of 500 km/h will not be a problem.
How fast is 5G?
The actual download speed of a 5G network is 100 Mb/s (megabits per second) and the upload rate is 50 MB/s. Converted, which is 12 MB per second data download speed, download one hour Netflix high-definition program about four minutes.
ITU distinguishes between "peak data rate" (technically the highest possible in laboratory settings) and "experience rate" (user experience in the real world). 5G will have a peak data rate of 20 Gb/s (gigabits per second) for the downlink and 10 Gb/s for the uplink. As for laboratory testing, so far, Nokia and Samsung are able to cope with the downlink speeds of 10 Gb / s and 7.5 Gb / s.
When is the popularity of 5G mobile phones and networks?
The average consumer's time to get a 5G mobile phone is estimated to be 2020. According to Intel and Ericsson executives, the United States will see the first 5G compatible devices in 2019. However, the timetable of the ITU regards 2018-2020 as a “defining technology†period, so there may be some changes in this.
It is estimated that 5G will be opened in 2020. This time is based on the next-generation network launched every 10 years in the mobile world. Starting from 1G in 1982, entering 2G in 1991, and quickly entering 3G in 2000, the current 4G network landed in 2010.
Which frequency spectrum does 5G use?
Is your mobile network the fastest? If not, which spectrum do you fall on? These mobile network symbols can be confusing, but don't worry, we will make it clear to you.
According to the FCC, the US 5G network is expected to operate in the 28 GHz, 37 GHz, and 39 GHz frequency bands. In general, 5G will start at 30 GHz so that it can use millimeter waves. For comparison, 4G operates at 700 MHz and 2100 MHz. Gigahertz is a thousand times stronger than megahertz. 5G is the first network to operate on millimeter waves, which will allow higher data transmission than current. Millimeter waves will also reduce the size of the required antenna. This means that wearable technology is more suitable for connecting with 5G.
What is the difference between 5G and 4G?
For end consumers, 5G will have real benefits:
First, faster download and upload speeds.
Second, better video call quality, especially when moving.
Third, better mobile phone battery life.
Fourth, the augmented reality experience is good because 5G can track users in real time and load data faster.
Fifth, can experience virtual reality with mobile phones, because it can support the speed of 4K videos on mobile phones.
Sixth, the enhancement of wearable technology, such as a fitness bracelet can track your every move.
Seven, more Internet of Things and smart devices, because the 5G antenna is smaller, the battery efficiency is stronger than the current technology.
VIII. Better experience for driverless cars because delays are greatly reduced.
The benefits of 5G are endless and of course include indirect benefits. For example, it brings long-term cost benefits to the mobile industry. Conversely, these benefits will also bring new benefits to consumers.
Although some operators appear to be selling 5G, the fact is that they are based on LTE's faster download speeds. When you have these 5G common sense, you can intelligently distinguish these dazzling advertisements.
