Wireless roaming, also known as roaming WiFi, allows devices to stay connected to a network while moving between different access points. The roaming WiFi is an event where a client device connects to another network after moving away and outside the range of an access point. The data roaming WiFi router is commonly used in large areas like offices, educational campuses and malls.
How Does WiFi Roaming Work?
Roaming WiFi operates by switching your device’s connection from one access point to another with minimal disruption or interruption in connectivity.
When a device moves closer to a new access point with a better connectivity signal, it automatically disconnects from the current network and connects to the new one.
To truly understand how WiFi roaming works, you must understand these factors:
Scanning
Authentication
Re-association
The client device scans the surroundings by sending probe packets to identify another viable network. Once that is done, it sends a request to the access point for authentication. Once the request is accepted, the client device sends a re-association request.
After this, the device and the old network are disassociated, and the device connects with the new access point.
Wi-Fi Roaming vs. Traditional Wi-Fi Connection
Traditional WiFi connections stick to one access point, even when its signal is weak on the outer corners of the range. This usually affects your performance quality and speed, leading to possible disconnection.
The data-roaming WiFi router enables a seamless transition between access points, which helps you maintain stable connectivity and optimal performance. This is very important for activities like video calls, where interruption can be disruptive.
How WiFi Roaming Works with Routers and Data Roaming
Data roaming WiFi routers rely on multiple access points connected to the same router or network. The router coordinates the handoffs and exchanges between the access points. Data roaming differs from WiFi roaming in that it involves switching between mobile networks rather than WiFi networks.
