On 4G the comparable daytime numbers were 130 Mbps download and 50 Mbps upload (4G does better at night when the network is less congested, with 200/100 upload/download Mbps). Emerging architectures that shorten the path length, e.g. edge caching and computing, may also confine the latency. Application performance.
