5G Network has arrived, deployment started in 2020

In recent years, because of the development of mobile phone design, the global wireless industry leader believes that the fifth generation of mobile communication technology, 5G, will be the next important development trend, the Reuters website said in Sunday. They expect the 5G network to begin deployment in 2020.

The following is the full text of the article:

People in the mobile industry need to first determine what difference 5G can make relative to 4G technology. "It's not clear what kind of opportunities 5G can bring and what flaws to address," the GSM association said in a report last December. ”

Mobile operators generally believe that unless the next generation of mobile communications technology can lead to a noticeable increase in speed and functionality, there is no need to invest heavily in building new network facilities or forcing users to upgrade to new handsets.

Industry experts point out that as the discussion of 5G technical standards has not yet begun, the final standard is likely to be completed by 2019. However, it has not stopped traditional equipment makers such as Huawei and Alcatel-Lucent, as well as many emerging companies from launching 5G projects. Most industry experts believe that the first commercial deployment of the 5G network will be in Tokyo hosting the 2020 Olympic Games.

"Before that, manufacturers need to do a lot of marketing," says Lauri Oksanen, vice president of Nokia Network Business Research and Technology (Lauri Oxanin). "In this area, Ericsson and Nokia will showcase the latest 5G projects in this week's Mobile World Congress with a number of other equipment makers," MWC said.

Internet of things as the main application

There is no doubt that for ordinary users, 5G is more advantageous than 4G, such as video viewing, download speed and network coverage. Mainstream manufacturers expect 5G networks to be 100 to 1000 times times the size of 4G networks.

However, the technology will also face new challenges: on a global scale, the spectrum resources at lower frequencies are largely depleted. and the higher frequency spectrum is usually only used for short distance communication. At present, these bands are mainly used by interconnected devices to form the so-called "Internet of things". The Internet of things will be one of the biggest applications of 5G.

For example, interconnected vehicles will be equipped with collision detection systems, real-time navigation capabilities, and automatic braking systems, and interconnected factory equipment can be remotely monitored to see when additional raw materials or malfunctions are needed, and many families have purchased interconnected household equipment.

Sara Mazur, head of research at Ericsson, said: "In the future world, all devices that can be networked will be networked, and almost all devices are Sala Mazul." "As the world's leading mobile device maker, Ericsson expects the total number of interconnected devices to reach 50 billion by 2020."

Application scenarios are still limited

Such scenes are only ideal, and the mobile communications industry has painted too many optimistic scenes in the past. Simply put, 1G realizes mobile phone, 2G realizes SMS, digital voice and mobile Internet, 3G brings the mobile internet based on picture, and 4G drives the development of mobile video.

The GSM association estimates that global operators will invest 1.7 trillion of dollars to upgrade their network equipment by 2020. Most of these will be used for the expansion of 4G networks and to enhance coverage in areas with high traffic volume.

"The device makers are keen to have a big bang because they will be able to sell more," said Gao Tai Miller, a Telefónica. And for 5G, we saw some incremental upgrades. 4G life is still a long time. ”

It can be said that 5G brings many "mutually exclusive" features, such as very high network speed, higher data service capacity, lower latency, and broader, more intensive coverage. These properties only make sense in certain scenarios, but none of the devices require them at the same time.

Complicating the situation, some proven technologies are currently being used for short-range communications, but these technologies are not in the hands of the mobile industry, such as WiFi, Bluetooth and near-field communications (NFC). These technologies have been supported by manufacturers of chips and digital products.

For example, Apple's newest iphone has a WiFi call feature, which means that users do not need to use a mobile communication network to call.

Bent Nordstrom bengy Nordstrom, head of strategy consultancy, said: "The northstream and operators who discuss 5G technology believe that all wireless devices should be connected to their network." Their ideals are great, but what we are talking about now is no longer a traditional mobile operator business. "(D-Gold)
