Due to the burstiness and randomness of a large number of nodes deployed by users, the network topology and interference have a wide range of dynamic changes. The number of service users in each station is also likely to lead to service space and time. The distribution shows dramatic dynamic changes. So, this is a major promise for 5G - that is, at very high-frequency bandwidths, it can bridge the previous mobile technology Unable to connect the gap. “For LTE/4G, the industry is approaching the theoretical limits of time and frequency utilisation.
The next step in 5G wireless technology is to use spatial dimensions to transmit any given frequency as often as possible by transmitting strictly focused signals in different directions. The industry still needs to overcome the challenges when using these two technologies for 5G. In 2017, these two themes have been progressing and changing, and you may see more in these two areas in 2018.
5G has higher speed and wider bandwidth. It is expected that the 5G network speed will be 10 times higher than that of 4G. It only takes a few seconds to download a high-definition movie, which can satisfy consumers' higher virtual reality and ultra-high definition video.
Network experience needs.5g technology has higher reliability and lower time delay, which can meet the specific needs of industrial applications such as intelligent manufacturing and automatic driving, broaden the development space of the fusion industry, and support economic and social innovation and development.5G is still in the research stage of technical standards, and 4G will maintain its leading position and achieve sustained high-speed development in the next few years. Millions of people have been unable to access reliable Internet access channels. Therefore, many people are worried that many countries will not be able to afford the huge cost of 5G, thus expanding the global digital divide.
This kind of risk always exists, but one of the big thing’s operators do in 5G is that they use it in a very high-frequency space, the so-called millimeter wave.
In this area, the amount of bandwidth is very high, this It is ideal for developing peer-to-peer communications in rural communities and remote areas. "This is ideal for providing the last mile connection because it is not possible with fiber-optic bands. From the perspective of industry application, 5G has higher reliability and lower time delay, which can meet the specific needs of industrial applications such as intelligent manufacturing and automatic driving, broaden the development space of the fusion industry, and support economic and social innovation and development.
Accurate and effective perception of neighbouring nodes is a prerequisite for large-scale node cooperation. In ultra-dense networks, dense deployments result in a dramatic increase in the number of cell boundaries, combined with irregularities in shape, resulting in frequent and complex handovers. In order to meet the mobility requirements, a new switching algorithm is bound to emerge; in addition, network dynamic deployment technology is also the focus of research.
