Getting connected to the Internet used to involve numerous rituals and pieces of equipment that now seem archaic and unnecessary.
Dialling up your ISP, disconnecting when someone wanted to use the phone and sign-up discs have all been consigned to history and physical wires are becoming less and less commonplace as Wi-Fi becomes increasingly available at home, at work and on the move.
World of Wi-Fi
Free public Wi-Fi has become almost ubiquitous on the high street. Where coffee shops led the way, pubs, supermarkets and retailers have followed, offering customers free connectivity in a bid to find out more about their clientele and to get more people through the door.
Communications providers are building nationwide networks of hotspots, boosted by ‘homespot’ technology that turns home routers into public access points. Wi-Fi aggregator iPass estimates there are more than 104 million hotspots around the world and expects this will rise to 340 million by 2018.
