Do you have any questions about wi-fi?

The city is covered by a wi-fi network which lets people access the internet and web services free of charge.

The technology section will be using the wi-fi network in an experiment to work away from the office - examining issues such as internet telephony, wireless gaming, the remote office, and assessing the views of people in the city.

We want you to take part in the wi-fi day out.
