Do not just want to film | 4 answers to help you solve all the questions 5G

Apple iPhoneX evaluation: I believe you have been a word by the end of 2017 - 5G brush screen, but also to open a unified conference to develop 5G standards, but also operators start 5G field test, very lively.

Just like 3G began to layout 4G, in addition to speed, we do not understand what it can bring us any benefits, only until 4G fully rolled out, we know that 4G contrast 3G is simply a qualitative leap, 4G can make Terminal is more flexible, more intelligent, while 4G has better compatibility, with a variety of network interconnection.

So 5G popularity, in addition to speed 4G will certainly have a 'volume' leap, the other 'leap' can only be spread until 5G to feel it?

Do not worry, this article will answer four questions, to help you fully understand what 5G can do.

How fast is the 5G speed? The next movie takes only 1 minute

Speaking of 5G, your first reaction may be fast, but 5G speed in the end can have more? What causes the speed?

As we all know, nowadays our mobile Internet uses wireless communication technology. To put it bluntly, it is electromagnetic wave. However, the frequency of electromagnetic wave is limited, and there are many different types of work that need to use electromagnetic wave.

Therefore, these frequencies can not be used indiscriminately. According to different frequencies, the global negotiation unites different uses uniformly. For example, extremely low frequencies are used for ultra-long-range navigation and the highest frequencies are used for waveguide communications.

The frequency of our mobile communications, is assigned to the IF - UHF. From 2G to 3G until 5G, that is actually frequency Increasing.

As the frequency increases, the frequency band is also gradually widened, for example, 4G period, the frequency band used by China's operators is roughly 2555-2575MHz.According to the Ministry of Industry and Information Technology issued a notice earlier, China's 5G initial IF band For the 3.3-3.6GHz, 4.8-5GHz two bands currently used mainly in the international test 28GHz.

We can compare the frequency band to a high-speed lane, and as the frequency band increases (the lane gets wider), the rate of traffic flow naturally increases (the car travels faster).

So how fast 5G in the end it?

In October 2014, the 5G network studied by Samsung had a maximum transmission speed of 7.5 Gbps at a standstill while the maximum speed was 1.2 Gbps at a speed of 110 kph.

In July 2014, Ericsson announced a peak transmission speed of 5Gbps in a wireless test of 5G wireless technology.

If we reach it 5Gbps speed It takes only 80 seconds to download a 50GB movie, which is currently wired fiber 1Gbps transmission speed 5 times.

Driverless rely on 5G to save

Speaking of the low latency of 5G, you probably do not have much-needed appetite for just using your mobile data connection, but the major driverless car companies are eagerly awaiting this technology.

Imagine if you were in an unmanned high-speed driving car and suddenly had an emergency in front of you. Your car detected a front-end accident and started to send back data. If you use the 4G network, it will slowly return as an old man Data, but if you use 5G, it will be in the flashlight back to the data between the fire when the eyebrows, of course, is faster 5G to save you and water and fire.

So 5G is how to achieve low latency?

Before we talk about 5G, we first look at LTE latency caused by those factors. As we all know, LTE delay is caused by air interface delay (4ms), core network delay (1-2ms) and PDN network delay (5-6ms) 10ms) affected, in general, even if the laboratory to maintain the state, LTE should have 10 ~ 16ms Delay.

So 5G solution Delay will start from these issues.

The current 5G solution is to reduce the air interface delay to 0.5ms, the minimum total delay of 1ms.

such, 5G to achieve a very low delay.In fact, not only driverless, many in the 4G network age cloud-like "stubborn disease" to 5G low-latency features will be resolved.

For example, when a doctor remotely operated on a patient and was still in the age of the 4G network, it would have been difficult to implement highly accurate operations. By the age of 5G, extremely low latency would allow physicians to be immersive in real time Surgical for patient safety.

Internet of things will usher in the eruption with 5G

The Internet of Things is also a long time ago by the technology circle speculation in full swing, but so many years have passed, but has been in the embarrassment, no less than no less than the situation.

In the final analysis or because Power consumption Bandwidth speed and cost reasons, and this problem with the advent of the 5G era will no longer be a problem, then, the Internet of things will usher in its second spring.

When it comes to the Internet of Things, at a macro level, it is to transmit information on the Internet. At the micro level, it is necessary to open up all the LANs, smart hardware and sensor devices.

Due to the low frequency band of the 4G network, it can not accommodate the most numerous IoT devices, which is a bottleneck in the development of the Internet of Things. However, this stumbling block will no longer be a problem in the era of 5G. Since 5G base stations can support hundreds of antennas, Large-scale antenna arrays can be formed with Massive MIMO technology, which means that base stations can send and receive signals simultaneously from more users, increasing the capacity of mobile networks by tens or more times.

At the same time, there is a pain in the Internet of Things, which is the power consumption problem. In fact, the shared bicycle in the full street is an IoT device. However, because the shared bicycle needs to be stored outdoors for a long time and still needs to have electricity all the time, Became the biggest pain point of the Internet of Things.

Then 5G is how to solve this problem? Is the prelude and basis of 5G - NB-IoT, because of its focus on small data volume, low-rate applications, so NB-IoT device power consumption can be very small, can be easily achieved A few years or even ten a few Years of life.

5G packages will be limited? Unlimited traffic as possible

4G just popularized when there is such a piece 'China Mobile launched 4G package, 40 yuan package 300 trillion traffic, according to the rate of 100 megacycles per second, this package will run out of 3 seconds, 40 seconds for 3 seconds, an hour is 48,000 yuan. If you forget to turn off the 4G connection at night, you wake up and your house is almost moving. '

It is not hard to see that people worry about new technologies. Facts have proved that such worries are completely unnecessary. By the time of 4G, the demand for traffic surged and operators naturally reduced their traffic tariffs.

5G network period is the same reason, according to 5G this 'speed of light' speed, I guess, 5G period of the flow package will be unlimited flow mode, because the only way to carry unmanned, Internet of things, high-speed Internet ... these 5G ecological prosperity.

However, operators once taking hold of the Internet's lifeline once they have been marginalized, because in the past no matter how cheap the traffic, how fast the network speed, traffic is always 'limited', we will take it into account. The operator is always in the center of the stage.

If you have unlimited traffic, will you still be using calls and texting?

WeChat has support CallKit

As early as iOS10, Apple opened the phone to third-party developers - CallKit privileges, third-party software through this permission can be put into the software's iOS voice system voice, that is, with this permission, the first Tripartite software calls and phone calls themselves have been at the same level.

The first time after two people meet, they may have to leave their cell phone numbers for future contact, but by now most of them only add WeChat.

Then when the 5G era has unlimited traffic and it is more convenient to communicate on WeChat, will people still pay for the telephone communication?

In the 3G era, QQ and WeChat got rid of the SMS function, and in the 5G period, it seems that calling is the next victim. Of course it does not mean that we do not call any more. It just means that since we have unlimited traffic , Then why do we have to be alone Voice communications pay carriers.

At this point, operators, has completely become a 'small trader' to buy traffic.

In general, 5G gimmicks at this stage mean greater than its practical significance, but once the 5G network spread, we can most truly feel the magic of 5G, 5G bandwidth, delay, power consumption Outstanding performance, it can even lead us into a new era - a Internet of things, a world dominated by data "world."
