With the passage of time we have come to a stage where we are surrounded by various devices using WiFi as a medium of connectivity. But there is a problem, i.e. we can connect to only one WiFi device using our current WiFi radio at any given moment.
Is there a workaround for that? And why is that limitation with this?
The CSMA/CA algorithm requires the AP to "coordinate" all the clients. If clients talked with other APs or with each other, it would be impossible to prevent interference.
Furthermore, the assumption is that your client is using Wi-Fi as an access layer technology to connect to a larger network. Why would you need to connect to more than one?
There is a mode called "ad-hoc" which doesn't use an AP, but allows nodes to talk directly to each other. This has been used for mobile networks where topology varies dramatically over short timespans, like seconds.
