What You Should Know About Wi-Fi

What is Wi-Fi?

Wireless LANs (local area networks), are also known as "Wi-Fi", or "hotspots". The technology is relatively simple and cheap to deploy, and is capable of transmitting data at far higher speeds than current wireless networks.

The momentum around Wi-Fi continues to grow, with a recent surge in operators deploying Wi-Fi networks. The challenge for cellular carriers moving to deploy Third Generation (3G) wireless networks that offer high-speed Internet services is that they usually make most of their money from heavily used parts of their networks -- usually in city centers, exactly where Wi-Fi providers are deploying their services.

Wi-Fi networks do not typically work when users are in motion (driving, for example). However, innovations in Wi- Fi technology also are occurring at an impressive pace. For example, new products have been developed for wireless billing and receipt printing by commercial businesses and retail outlets. These products will enable small businesses to easily and cost-effectively install hotspot access points for wireless connectivity and tie multiple Wi-Fi access points together into workable systems with authentication, billing, pre- and post-paid billing, and credit card management.

Wireless operators in the United States are recognizing the advantages of using public Wi-Fi access to complement their wireless data offerings and see hotspots as an immediate revenue generator for data service. For example, T-Mobile, a nationwide wireless operator in the United States, has been promoting Wi-Fi access through Starbucks. ATT provides Wi-Fi in McDonalds and various other locations. Verizon Wireless is converting payphones in New York City to wireless hotspots.
