security isn't the main concern; the real challenge is that only one person may speak at a time in a band. If Wi-Fi covered an entire city, the available bandwidth would be extremely limited—only three 2.4G bands exist without overlap, meaning just three devices could communicate on 2.4G, which explains part of why the FCC restricts it. Microwaves use similar frequency ranges, and while they're not harmful in small amounts, excessive power can cause damage. Mesh networks are typically wireless, with examples like OBI, Google Wi-Fi, TP-Link Deco, and others.
