Unfortunately "suburb" is an overloaded and ill-defined term that can mean anything from "pre-war streetcar suburbs laid out on a grid, with a main street, walkable amenities, and (at least here in the Northeast, if not everywhere) access to commuter rail" to "a modern cul-de-sac development attached to a high-speed arterial that's walkable to exactly nothing."
