In addition to fast speed, 5G is likely to disappoint you everywhere-Recent activities

Less than 4 years after the issuance of 4G licences, the construction of 5G networks is already in the firing line. According to media reports, China's three largest carriers will invest 180 billion dollars, and plan to build the world's largest 5G network in 7 years.

At the moment, consumer perception of 5G networks is faster. From 3G to 4G, consumers are enjoying the convenience brought by technological change. At the same time, consumers also expect that after the popularity of 5G network, the tariff will be lower and the signal coverage will be more perfect. From all aspects of information, in addition to fast speed, 5G network or let users more disappointed.

Signal coverage is hard injury

As the fifth generation mobile communication network, the most striking advantage of 5G is its faster speed. It is reported that the maximum transmission speed of 5G network can reach tens of Gb per second, which is more than hundreds of times faster than the existing 4G network. In the future, download the entire super high quality movie using 5G network, and download it in less than a second.

The fast 5G network is worth looking forward to when the 100 trillion broadband is not yet popular. However, 5G networks still have deficiencies in signal coverage. Because 5G network technology mainly uses ultra high frequency spectrum, this can provide higher data transmission rate, but the frequency range of electromagnetic wave transmission distance is very short, and easily obstructed by obstacles. To make the 5G network a better signal, operators need to build millions of small base stations, deploying them to every pole, every building in each building, or even every room.

Careful consumers will find that the speed of mobile Internet is increasing rapidly, and the number of mobile base stations will also increase. In the 2G era, the number of base stations in the operators was very small. After 2G signal coverage is mature, it is basically a town that only needs 1-2 base stations to achieve seamless coverage. After entering the 3G era, the number of base stations of operators has increased sharply, and there will be a blind area of 5 base stations in a township. After the popularity of the 4G network, we will find that several villages need a base station.

At present, 4G network licenses have been issued for more than three years, and many areas still have 4G network coverage problems. It is impossible to predict that the signal coverage of 5G networks is more difficult than that of 4G networks. According to the plan of the Ministry of industry and commerce, a large-scale trial network was launched in 2018, and the 5G network officially launched business services in 2020. Even so, the 5G network will still be damaged after commercial signal coverage, and the 5G signal will be even worse in tall buildings.

The embarrassment of rising flow rates

Forget to move 4G, wake up and your house will be gone. The passage that has been circulated on the Internet reflects the fact that the 4G network is expensive. Under the policy of speeding up and lowering fees in the Ministry of industry and commerce, mobile Internet traffic charges have been cut down, but they are not close to the people. For this reason, many consumers put their hopes of lower fees on 5G.

From the evolution of 3G to 4G network technology, the overall fee is still rising, after all, the three major operators in 3G and 4G network construction has invested a huge amount of money. Data show that China Mobile, China Unicom and China Telecom three major operators in 2013-2020 years in the 4G network investment estimated $117 billion, which is also the root cause of the increase in tariff, after all, operators are not public welfare institutions, need to profit. The huge investment of the three big operators, the change in the tariff level is that the entry threshold has become higher. For China Unicom, the entry threshold of the 3G era is 66 yuan set meal, and the entry threshold of the 4G era is 76 yuan. Similarly, the access threshold for China Telecom and China Mobile has also increased.

According to the investment scale of the three operators in the 5G network construction, once the 5G network is commercially available, the tariff will be higher than the 4G tariff. In the same seven-year period, the three operators spent $117 billion on the 4G network and $180 billion on the 5G network, an increase of 48%. Imagine, in the 5G network, the investment of the three operators is higher, how can the tariffs drop, after all, the Ministry of Industry and Information Technology and profit indicators of KPI assessment

In addition, the shorter change time of network technology standards is also an important reason for higher 5G tariff. In 1994, Fujian opened the first GSM digital mobile phone in China; in December 2008, the Ministry of industry and information issued 3G licences to the three major operators, and the 4G license was issued in December 2013. Upgrading from 2G network to 3G network is 14 years apart, and 3G network upgrade to 4G network takes 5 years. In such a short period of time, network technology is frequently upgraded, and operators are bound to bear a greater burden. In order to recover the cost faster and improve the cost, it is not difficult to understand.

5G cell phone is facing a challenge

In recent years, many consumers have Spears on smartphones. Back in the 2G era, Nokia handsets were easy to stand by for a week, even if the phone was busy every day and charged every two or three days. After entering the 5G era, a worse life experience than 4G mobile phones will disappoint consumers.

In fact, as early as the 3G era, the continuation of smart phones has made consumers feel puzzled. Compared with 2G mobile phones, the 4G phone with larger battery capacity is much different in standby time. In many mobile applications, data traffic is the most power consuming application. People in the industry say that the faster the Internet is, the more power it will be. If this theory is set up, it may be a half day to use a 5G cell phone.

With Apple phone, we can find the change of mobile phone under different network technology. The iPhone 4 battery capacity that first entered the domestic market is 1470 Ma, and can be maintained for one day under the condition of non severe use. The latest generation of iPhone 7 Plus battery capacity is 2910 Ma, and the use of 4G data is not supported by the Internet. It is not difficult to find that the standby time does not change much when the battery capacity almost doubles, suggesting that the faster the Internet access, the more power the phone consumes.

With battery technology already encountering bottlenecks, the 5G network is indeed fast, but the problem with it is that it will last longer. Although Huawei and Kinley have introduced longer-lasting phones, mobile phone service is still a hard indicator of consumer experience in the 5G era.

In short, the perception of 5G network to ordinary consumers is only faster. Like other technologies, 5G technology has encountered bottlenecks in its development. So, apart from fast Internet access, 5G networks with poorer signal coverage and higher fees really don't have much to expect from consumers.
