Eli5:Why is it that cell phones , with their tiny antenaes are able to download files at LTE speeds inside concrete buildings from cell towers kilometers away yet getting wifi to work behind a corner is an exercise in frustration?

The real answer here is because they were designed that way. Wifi is designed to use public frequency bands and for short ranges so they won’t have a large negative effect on other people using those same frequencies for their own use. Most people don’t want or need their WiFi to span a mile from their house. Cellular technology is built to use reserved frequencies that won’t conflict and is built to travel long distances.
