3G + Wi-Fi - Computer Definition
Devices that have third-generation (3G) cellular data service as well as Wi-Fi. Apple's iPad and Amazon's Kindle reader were some of the first products to be offered in 3G + Wi-Fi models, the latter enabling downloads whenever the user is in range of a cellular tower. On Wi-Fi-only models, the user must be within the proximity of a Wi-Fi hotspot at home or office or venues such as hotels and cafes. See cellular generations, Wi-Fi and Wi-Fi hotspot.
