Since the end of this year's MWC, it is certain that 5G has become the focus of the global technology industry. However, after entering 4G from 5G, the whole wireless communication market talks about not only the increase of transmission speed, but also the diversification of the application market, which further affects the overall infrastructure and software and hardware issues. There are so many that it is difficult to use a limited space. However, it can be confirmed that once the application form officially enters 5G, the competition between its industry and the market will become more diverse and complex.
5G will be able to achieve "programmable world"
Since NOKIA (Nokia) acquired Alcatel-Lucent, 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 Communication Technology Innovation Department Asia-Pacific industrial environment total Manager Chang Jiang said that 5G will be a "programmable" world for NOKIA.
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 design the antenna array, but the design challenge will also increase.
How to quickly and dynamically meet different business models, how to manage and expand the infrastructure resources, has become an important challenge, and to be able to cope with the practice, probably left in the IT field for years of virtualization.
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 and further different. The business model, which must use more network architecture, is there 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 development of the programmable world.
Figure 1: In the future, all business models will move toward personal centers, and 5G is known as one of the roles that fuels the waves.
PPS Expandable Braided Sleeve is a type of protective sleeve that is used to protect and organize cables, wires, and hoses. It is made from a high-quality polyester material that is braided in a tubular shape. The expandable design allows the sleeve to easily expand and contract, accommodating different sizes of cables and wires.
