Not only fast, 5G 4G can not be replaced by the new value

In the 2017 MWC, referred to as the fifth generation of 5G wireless communication technology, as the focus of this session of the General Assembly, Intel and Qualcomm each show for the 5G developed by the wireless communications products, and even each other through the media conversation, competition (International Telecommunication Union), 3GPP (3rd Generation Partnership Project) and other standardization bodies are also privately under the dark disk rivalry, scrambling to be in line with the hardware level of the two giants on behalf of the hardware, To create the best 5G universal standard. More and more action and competition, all represent the popularity of 5G days seem more and more close to us.




However, some people may have doubts, in fact, 4G-LTE has to meet our daily needs, in addition to sometimes face the problem of network congestion, whether it is to see Youtube, Netflix, or playing online games, we have very little Encountered the problem of insufficient bandwidth Moreover, the global coverage of 4G is about 70% of the case, 5G whether there is such a need to start layout so early?


Why do we need 5G network?


Relying on the past 10 years, the growth of intelligent mobile phone, people demand for the times with the times, streaming music, audio and video because of the development of wireless networks and the rise of the past, people need to watch the audio and video, listening to music , But also because of the growth of wireless networks have changed. Light to audio and video specifications, and soon, people will not be satisfied with the resolution of Full HD, and would like to 4K, or even 8K resolution into the people, the demand for wireless networks will only be more and more , So once the 5G gradually popular, many need to download faster service and application will be quickly popular.


At present, we are 5G imagination and requirements, nothing more than is the rapid, low delay (Delay), security of these items, while many manufacturers and standard alliance, is also expected to 5G can bring a better change, so that action Medical, smart city, car network (smart car), unmanned and so on have now developed technology has become more reliable, after all, you should not want to self-driving from the network to capture data, the network delay is too serious , The current 4G technology in the point-to-point connection delay of about 50 milliseconds, can not achieve real-time control and command, but the current 5G technical point-to-point online delay of about one millisecond, in such conditions, real-time transmission orders through the network more May be achieved, and therefore in addition to smart phones, the car network will be in addition to mobile phones, tablet, laptop and other traditional mobile devices, the first benefit from the 5G intelligent device.


5G network now how the development of the situation?


Many research and reports indicate that 2020 will be a key year for 5G services, because it is the world's many telecom companies want to be able to publish 5G service time point, in fact, the US telecommunications giant Verizon has been with Cisco, Ericsson, Samsung, Nokia Cooperation, intends to begin in 2018 to build 5G network, hoping to catch up to 2020 will be able to achieve 80% coverage in order to achieve such as 4G commercial targets.


At present, the 5G standard has a number of league competition, but basically 5G specifications technical guidelines probably have the final set (see below). As mentioned above, even if there are ITU, 3GPP and other alliances in the development of 5G standard, so each alliance in the description of the specifications of the 5G are somewhat different, but in the end in order to be able to facilitate the promotion, extension that 5G unified day from now Not far, there will soon be a common technical standards released.


Qualcomm in the fourth quarter of 2016 published Snapdragon X50, is the world's first 5G Modem chip, the initial application can be used in smart phones, home wireless networks, cameras and other fields, download speeds up to 5Gbps, 2018 is expected to be available in the first half; And in 2006 to sell the mobile chip business Intel, then in January CES release can support 6GHz below the millimeter-wave band with a common 5G modem, which can support high and low frequency products.


In the current mainstream plan, the United States took the lead in the global release of 5G spectrum plan, in July 2016 the US Federal Communications Commission (FCC) announced its 5G high-frequency resource allocation plan (see below), and the EU RSPG and China IMT -2020 (5G) to promote the development of the group planning, basically grasp the high and low frequency band synergy, low frequency as the basis, high frequency to supplement the principle of the current global spectrum planning integration is not high, the use of 5G spectrum Has not yet reached a consensus, but if the global use of the same band, for the country's telecommunications business is a big advantage, which means that roaming easier, but also reduce costs, as a 5G service to accelerate the expansion of one of the important incentives.


At present, Intel's 5G Modem on the emphasis on the global common, support the following 6GHz band (3.3 to 4.2GHz part), millimeter-wave band, ultra-wideband operation, ultra-low latency Gbps-level network throughput to meet the critical 5G technical requirements, Including the expected speed of more than 5Gbps, hundreds of MHz of the aggregate bandwidth, but also support 5G NR and other key technologies.


In addition to fast, 5G will bring what value?


In view of the current 5G plan to see, telecom operators from 4G to Pre5G stage, the device does not have to spend more cost to set up base stations, only the original base station upgrade can continue to use, just as the original 3G upgrade directly to the LTE, the expansion is easier, while the cost can also be reduced, and to things networking, car networking as the final trend of development, including Bluetooth, Wi-Fi, ZigBee and other wireless technology is also evolving, Although each have limitations, but there is a gradual convergence of the situation there.


Network equipment maker Ericsson believes that 5G will be an "incredible opportunity", the company estimates 5G will bring in the 2026 US dollars 1.2 trillion dollars in economic scale. High-speed and stable wireless communication, will bring the better content, from the voice, live, to the car network and even things, many of the original 4G era is limited by speed, stability, service and applications, will be in 5G era show more head angle, for the average user, the network video upgrade will be the first wave of shock, has been considered not rapid development of the car network, Internet of things, intelligent city vision, are likely to follow the 5G Popularize the pace of implementation.
