Roaming support is essential for providing uninterrupted connectivity for users who are moving. Roaming is supported for mobile phones, but is not as extensively available for users of Wi-Fi computer networks. Wi-Fi users can typically roam with little or no interruption when moving between wireless access points on individual local area networks, but often experience trouble when roaming around large school and business campuses. Generally, people find Wi-Fi roaming to be nonexistent when moving between different areas in a city.
