What is the best wifi design in use?

Mr.Alan i agree with you.Wireless mesh networks are 'multihop' systems in which devices assist each other in transmitting packets through the network, especially in adverse conditions. You can drop these ad hoc networks into place with minimal preparation, and they provide a reliable, flexible system that can be extended to thousands of devices.The gateway MeshAP (that is, the MeshAP that is connected to the internet) can obtain its internet access from WiFi, local broadband, dial-up modem, ISDN or even a self contained GSM/GPRS module for really unconnected locations.

Dear Green,

How secure is Mesh AP in the users point of view?

Multipoiint mesh is the key to deploying a reliable wifi network. The probelm with standard wifi using a star type opf layout, if you knock out the AP the who network stops. If you know out the AP in mesh, the network automatically reroutes traffic and reheals automatically.
