Simply put, it is impossible to take the high-frequency route at all. The frequency above5Gis totally useless, and the coverage is too small. Only one path can be called5Gif the multi-carrier system is based on LTE, at least more than three carriers. As for those who say 5G network system needs Gigabit level and blowing water, there is no practical application at present. (TD high-frequency mobile phones can be used under the base station, or up to 100 carriers.) Mega, but the actual long-distance, is a slag, just to catch up with wcdma. In reality,China's spectrum resources are limited, and the number of users inChinais huge. Many dense areas have emerged. The first-class signal stick and the network speed are too slow. This is the lack of bandwidth per capita, or the signal is very good, but the network can not be registered, and the bandwidth is full... So,5G, the most likely solution is multi-carrier, but multi-carrier is now defined as4G+, so the situation is awkward... In fact, the5Gstandard has not yet been formulated, so the future 4G and LTE-based multi-carrier technology should also dominate our communications for several years.
