The government too recognizes the importance of speed in mobile computing. In February, Congress opened the door to an increase in network capacity for mobile devices, proposing legislation that permits the auction of public airwaves now used for television broadcasts to wireless Internet suppliers.

Overcoming speed bumps is part of the history of the Internet. In the 1990s, as the World Wide Web became popular, and crowded, it was called the World Wide Wait. Invention and investment answered the call.

Laying a lot of fiber optic cable for high-speed transmission was the first solution. But beyond bandwidth, the Web got faster because of innovations in software algorithms for routing traffic, and in distributing computer servers around the world, nearer to users, as a way to increase speed.

Akamai, which grew out of the Massachusetts Institute of Technology’s Laboratory for Computer Science, built its sizable business doing just that. Most major Web sites use Akamai’s technology today.

The company sees the mobile Internet as the next big challenge. “Users’ expectations are getting shorter and shorter, and the mobile infrastructure is not built for that kind of speed,” said Tom Leighton, co-founder and chief scientist at Akamai, who is also an M.I.T. professor. “And that’s an opportunity for us.”

The need for speed itself seems to be accelerating. In the early 1960s, the two professors at Dartmouth College who invented the BASIC programming language, John Kemeny and Thomas Kurtz, set up a network in which many students could tap into a single, large computer from keyboard terminals.

“We found,” they observed, “that any response time that averages more than 10 seconds destroys the illusion of having one’s own computer.”
