Say you’re mingling in a room full of people, enjoying a tasty beverage. It’s a polite room of people who listen and respond during pauses. (So you’re in Canada!)
Out of nowhere, a mass of large, loud people enters the room, shouting instructions to each other. It’s like they’re oblivious to anyone who isn’t them.
In wireless protocols, the Canadians are WiFi. The Large Louds are LTE.
