Most smartphones have 3G, or third generation, capabilities. This means they can work with 3G cellular telephone networks that have broadband-quality connections. Download speeds up to 1.4 megabytes per second are available. We are even seeing 4G connectivity these days, which is even faster. Wi-Fi, also called 802.11, lets users access the Internet wirelessly at home, in coffee shops and at many other places. Wi-Fi is often free, but requires users to be near a wireless router.
