WiFi Access is one thing that people can't live without. Traditionally you need something called WiFi Router through which you can access Internet.
WiFi Routers have a range of around 30 meters. In case you need to access beyond this range, you need something called WiFi Repeater / WiFi Range Extender.
WiFi Repeaters have some limitations though. Some of them are enumerated below.
- WiFi Repeaters are not that easy to configure
- Sometimes they create a new Network
- There might be some compatibility issues between multiple vendors
WiFi Systems address the above limitations. They are easy to configure. There will be exactly one WiFi network with a typical WiFi System and there will be smooth roaming for clients between Routers.
People started moving towards WiFi Systems from traditional WiFi Routers / WiFi Repeaters and next few years belong to WiFi Systems.
