Wireless Networks Questions Medium
Wireless roaming refers to the ability of a mobile device or user to seamlessly connect to different wireless networks while moving from one location to another. It allows users to stay connected to the internet or a network without interruption as they move between different coverage areas or access points.
When a device roams, it automatically searches for and connects to the strongest available wireless network in its vicinity. This can be particularly useful in situations where a user is traveling or in areas with multiple wireless networks.
Wireless roaming is made possible through the use of protocols such as the Wireless Local Area Network (WLAN) standard, which enables devices to switch between different access points without losing connectivity. It relies on the concept of handoff, where the device seamlessly transfers its connection from one access point to another without any disruption in service.
Overall, wireless roaming enhances the mobility and convenience of wireless networks, allowing users to stay connected and access network resources regardless of their location.
