What you're looking to do is to create wireless roaming. To do this with stand along APs/wireless routers, you need to create a single SSID that is used by both (or multiple) APs/wireless routers. But with each AP/wireless router, you need to set the operating wireless channel to a unique one. So one would be on say channel 1 and the other would be on 6. On paper this looks like it will work and in many circumstances it does.
Here is the problem. Depending on the RF profile of where you want to implement this solution, you can have issues with RF interference on a particular channel. Layer this on top of having to depend on the wireless NIC driver of the device you are using and you can get mixed results. The roaming setup of many wireless NICs isn't really all that great.
With a wireless controller and lightweight AP setup, you have better unification of the wireless APs which means all the APs behave in a unified fashion. The system takes out the guess work of the wireless NIC driver and does the appropriate steering of the wireless device to the best AP for the best wireless connectivity. If you want the best possible solution, the only method is to use a wireless controller/lightweight AP setup or something in between which is a wireless mesh type system that approximates a wireless controller. |
