BT Openzone access points will allow diners to log on to the internet using wireless broadband if they use a Wi-Fi-enabled laptop or PDA. The deal is timed with the start of Wireless Broadband Week (from 26 January), when users will be able to try out services free of charge.
Most of these Wi-Fi-enabled sites will be at drive-thru restaurants, popular with business travellers. After the deal, there will be some 2,000 BT Openzone sites live across the UK.
Peter Richards, chief development officer at McDonald's, explained: "Today's customers are more time-pressed than ever and we think it's important to meet the needs of busy professional and family lifestyles by offering services that are easy to use and relevant. We want the 'golden arches' to be the first choice for a great meal and a place to go wireless."
Steve Andrews, managing director for products and enterprises at BT, said: "We have a vast network of BT Openzone access points at key locations for road warriors and those at McDonald's will help boost that network.
The sites will provide easily accessible locations for people who haven't tried Wi-Fi to log on for free during Wireless Broadband Week."
In the US, the fast-food giant has Wi-Fi in 400 restaurants.
