The BBC's Rory Cellan-Jones today looks at the impact of initial WiBro deployments in South Korea.

"In a high-rise suburb of Seoul, a shiny new bus is thundering through the streets," he writes. "On board, several laptops, some Samsung PDAs, and half a dozen local residents invited on board to try out a technology South Korea believes will give it a world first. It is part of a trial of what the Koreans call WiBro, which stands for wireless broadband."

The local residents, Cellan-Jones says, seem happy with the service. "I'm catching up with a soap opera," Lim Ji Young says. "My boyfriend is playing online games."

South Korea already has four homes in five with broadband, so a mobile option like WiBro, Cellan-Jones suggests, is a logical next step. "Take a trip across Seoul and you see a population apparently obsessed with being connected, anytime, anywhere," he writes. "Deep underground in subway trains, they are making phone calls, while in the park they are watching football games on their mobiles, or playing online games."
