1. When it comes to 6G, some netizens may say: now even 5g has not been used. Isn't it too early to study 6G? In fact, it's not early at all. On March 9, 2018, the Minister of the Ministry of instry and information technology said that China has started to study 6G technology. At present, research institutes in Europe, the United States, Japan and South Korea, which are powerful communication technology countries including China, have started the research of 6G network
according to this rule, if we look at 1g to 5g technology again, the context of its development is very clear:
1g technology is the pioneer of mobile communication. Before that, the telephone is fixed - people need to be in a fixed position to answer and make calls. The post-90s may not have seen such a contact information as "call 12345 to ask Uncle Wang of the reception room to call.". Therefore, although the "mobile phone" in the 1g era is large and expensive (it costs tens of thousands of yuan, but it was in the 1990s), its emergence finally let people get rid of the shackles and answer and make calls anytime and anywhere
2. there will definitely be a solution in the future, and there are a lot of arguments about the possible disappearance of WiFi now at the Guizhou digital Expo, Professor Lu Tingjie of Beijing University of Posts and Telecommunications said that 5g will be the basis of 4K and 8K video in the future, and WiFi is already a backward technology, so it is difficult to carry such a large bandwidth
in 5g, the coverage distance of uplink and downlink is quite different. In this case, the uplink and downlink decoupling technology is also introced, 4 / 5G common site construction, and 4G is used to meet the uplink coverage in areas with insufficient 5g uplink coverage
but even so, in the centimeter wave stage of China Mobile, China Unicom and China Telecom, the indoor attenuation of outdoor signal coverage is relatively large. In order to better meet the requirements of indoor coverage performance, a large number of small base stations will be introced into the 5g network
3. Compact and orderly organization is the key to make the trainees feel different. It can be said that it is not easy for a company to organize a training. HR department partners need to prepare in advance, find a teacher for class, and issue a notice for mobilization. In fact, many employees do not reject training at first. Why do they increasingly reject such "useless" activities after training? It's worth thinking about by our partners in the organization department. If a training starts from organization and preparation, activity notification and mobilization, as well as prior consultation or questionnaire feedback on the arrangement of training content, such training may not be useless, at least not offensive at first.
