====== Creating a high speed mesh by using dual radio nodes ======
* During an early demonstration of MESHdesk the first question that was asked: **Does it supports dual radio nodes?**.
* The answer at that time was //not yet, perhaps in the future//....
* Fast forward to today and we are proud to say that MESHdesk does indeed also support dual radio nodes.
------------------------
===== The limitations of single radio nodes =====
* Unfortunately with a mesh there is a performance knock with each hop away from the gateway node.
* This performance knock is unavoidable even with dual radio nodes.
* With single radio nodes there are however also the following to consider.
* When you use single radio mesh nodes each node has two functions:
* It has an ad-hoc connection with neighbor nodes. (This can be seen as the connecting wire between the nodes)
* It typically also has one or more SSIDs to which clients can connect.
* This means that each radio has to **time share** between these two functions.
* Add to the mix that the mesh and SSID's are all on the same channel and it does not take a genius to see why people will ask //Does this system supports dual radio nodes//
------
===== Dual radio node alternative =====
* When we have dual radio nodes we can create a mesh in the following way.
* Use the 5G radio for the ad-hoc connection with the neighbor nodes.
* Use the 2.4G radio for the SSIDs to which clients will connect.
* Make sure each node's 2.4G radio is on a non-overlapping channel (1,6,11) to reduce interference.
* Test shown that this configuration results in an increase of the throughput of nearly 3 times when compared to a mesh that consist of single radio nodes.
* See the following diagram for an overview.
