Where is public Wi-Fi access needed?

Nowadays hundreds of business travelers take into trip their mobile computer. Connection by modem while traveling is difficult, expensive, rather slow and limits users opportunities. Using Dial-up connection we must be very patient and have a stable psychology to receive big documents or use VPN connection for connection with a corporative network of company. Plans of trip can be frustrated by struggling with adjustments of Dial-Up connection or waiting for a loading of important document.
More and more people are planning their trip, guiding by opportunity availability to receive high speed access to Internet in places of their presence. In other words, they will prefer one hotel (café etc.) to another one, basing on availability of high speed access to Internet service in the first one. As business travellers are starting wondering whether   they can receive such service Wi-Fi in the given place, presence of Wi-Fi access is becoming an important competitive advantage.
Satisfaction of business travellers is only the top of iceberg. The service is constantly improving and gives more and more new advantages and profits both to operators and owners of access points.
