| + | ====== 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 <wrap em>MESHdesk does indeed also support dual radio nodes</wrap>. | ||
| + | ------------------------ | ||
| + | |||
| + | ===== 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 <wrap em>increase</wrap> of the throughput of <wrap em>nearly 3 times</wrap> when compared to a mesh that consist of single radio nodes. | ||
| + | * See the following diagram for an overview. | ||
