Wi-Fi Alliance has introduced a new certification program that will let users who have mesh network products set up in their homes or offices select devices from different products, without affecting the reliability of the wireless coverage. This is called the EasyMesh, the program which will reduce the reliance of customers on a single-vendor ecosystem and enable them to add various access points to their network.

EasyMesh certified products will make it easier for customers to extend their coverage. Currently, users can only add those products to the mesh networks which work with the main network gateway. For example, if you using the Linksys Velop to extend your network coverage, you will need to purchase two extra units of the same brand to form a mesh network. That was before because now, EasyMesh will end this restriction.
