Typical real-world latency is 30 ms, no better than good 4G. Verizon
Edge networks cut latency to 10-20 ms in 4G or 5G
Fiber latency is usually lower. Telus
Low-band “5G” today is no faster than 4G 6 independent tests
Mid-band 5G’s speed is 100-300 Mbps, similar to good 4G in the same spectrum. 6 independent tests
mmWave capacity is typically 3X mid-band but is <5% of 5G
5G NB-IoT is almost the same as 4G, unless 50,000+ local connections.
Wi-Fi is 90+% of IoT, not cellular.
3/4ths of 5G users are in China and Korea.
80% of Korea is covered. Swisscom and Etisalat Abu Dhabi are similar. I know no other countries more than 20% covered. I don’t count low-band at 4G speeds.
Virtual reality makes most people nauseous at 20 ms and some at 10 ms
Connected cars work fine at 4G speeds and latency. Only remote driving needs lower.
Autonomous cars do not require 5G. Ford
Almost all remote surgery will be over fiber, not 5G unless surgeons operate from the beach.
5G does not cost more than 4G. Telco capex is flat to down Verizon, Orange/FT, NTT DOCOMO, AT&T
More than 65% can be covered by 5G from existing cells. (Smart build) Only mmWave needs many small cells.
Factories and industrial Internet almost always work about the same in 4G as in 5G
There is no evidence that faster wireless speeds have a major effect on employment or the economy.
Why would watching more TV improve the economy?
Spectrum usually has minimal effect on deployment although it (modestly) lowers telco costs
Major exception: Big chunks at 2.5 or 3.5 GHz ideal for Massive MIMO 4G or 5G
Competition inspired AT&T, Verizon, and T-Mobile US to roll out faster.
Inspiring or ordering one carrier to build 5G will normally force others to respond
