The main focus of this year's MWC is the layout of the major manufacturers in 5G. Although the 5G standard is still in the discussion stage, the major manufacturers have demonstrated the investment and R&D achievements of 5G technology in MWC to enhance the visibility in the wireless communication industry. .

Since the acquisition of Alcatel-Lucent by NOKIA, the major suppliers of the global telecom equipment industry have been left, but this also makes the outside world pay more attention to NOKIA's strategic layout and trends in 5G. NOKIA (Nokia) Communication Technology Innovation Department Asia-Pacific industrial environment total Manager Chang Jiang shared the idea of ​​NOKIA for 5G to the Taiwanese media. For NOKIA, the future will be a "programmable" world.
NOKIA believes that in the future, after entering 5G, the range of applications covered is quite wide. For example, Industry 4.0, Internet of Things and M2M, which we are familiar with, will be the areas that 5G can reach. Chang Jiang believes that 5G will expand the possibilities of mankind, but the question is, how to do it? Chang Jiang further said that before this, several development trends must be met, such as expanding new spectrum, full dynamic resource allocation and omnipotent self-configuration. Under these development trends, some technical challenges will be derived. For example, the current wireless spectrum currently uses only 6 GHz, but in the mid-high frequency range, even the millimeter wave (mmWave) still has considerable space to be used, and it is possible to transmit 100 Mbps anywhere. . In addition, after entering the high-frequency field, the antenna volume can be greatly reduced, and the wireless communication device will have the opportunity to implement the antenna array design.
In terms of M2M, the actual system requirements, demanding ultra-low power consumption, operating time of up to ten years, small data transmission and low system cost, etc., this part of NOKIA has already demonstrated technology as early as MWC 2015.
Going back to the “programmable†world mentioned earlier, Chang Jiang believes that although the past commercial services are very close to individual needs, they are still limited. In the future, all services will be personally centered, which must use more. The network architecture of the yuan has a way to respond, so how to dynamically manage the multi-network has become one of the important topics in the 5G era, and network virtualization can just play such a role and drive the programmable world. development of.
However, the formulation of the 5G standard has been upgraded to a political battle between countries. The performance of major manufacturers in various countries has naturally affected the formulation of future 5G standards. Chang Jiang said that the EU will play a key role in the formulation of the 5G standard. The future development of 5G is believed to be a win-win situation. The technologies provided by various major manufacturers have the opportunity to appear in the 5G standard. For example, the 5G standard development will be carried out in two phases instead of all in one time, although It is aimed at different countries' attitudes towards the establishment of 5G services, but the idea of ​​formulating specifications in stages is proposed by NOKIA.
