is a term in radio telecommunications
that defines the switching of a mobile end-user's device from one fixed antenna
to another. Mobile phone
users typically 'roam' when driving on the road when their ongoing conversation is transferred from one antenna to the next when the first antenna's signal becomes too weak, hopefully without interrupting the call.
Roaming support is essential for providing uninterrupted connectivity for users who are moving. Roaming is supported for mobile phones, but is not yet available for Wi-Fi users. Wi-Fi connections get interrupted and have to be re-established when switching from one base antenna to the next.
