Carnegie Mellon's 103 acre (0.4 km²) main campus is five miles (8 km) from downtown Pittsburgh, in the Squirrel Hill/Oakland part of the city. A large grassy area known as the Cut
forms the backbone of the campus, with a separate grassy area known as the Mall running perpendicular to it. The Campus was the
first educational institution in the world to be completely covered by a wireless network. The campus computer network, Andrew,
is considered one of the most advanced networks on any campus in the world today.
