B、由于频率升高,视距传播距离限制,5G一般需要比 4G系统更为密集的基站体系

D、How much better than 4G will it be? It depends who you ask. Verizon has said that its 5G network will likely deliver speeds 200 times faster than many of its 4G LTE users get now. According to Gizmodo, 5G networks will have the capacity for transfer speeds 10 times those of 4G networks. Other forecasts vary considerably, with some experts saying that 5G connections will initially be about three times faster than 4G, and others making claims on par with Verizon’s. One big reason for those discrepancies is that 5G hardware standards haven’t yet been agreed upon by the telecommunications industry. The carriers are still developing several versions of the technology. So naturally, there’s no clear "speed multiple." But all companies involved are pursuing 5G that will be significantly faster than today’s mobile wireless connections. (5G 和 4G 对比,速率优势比例不确定,优势肯定有)
