In the context of wireless networks, a “Mesh” refers to a network that allows multiple access points to connect to each other without the need for a central router or switch.

At MikroTik, Mesh technology is implemented through a protocol called Mesh Networking, specifically using standards such as 802.11s or using MikroTik's proprietary protocol, HWMP+ (Hybrid Wireless Mesh Protocol+).

How the Mesh works in MikroTik

1. Hybrid Wireless Mesh Protocol+ (HWMP+): HWMP+ is a Mesh routing protocol that MikroTik has implemented for its Wireless devices. This protocol is based on the IEEE 802.11s standard, which is a default routing protocol for networks.

Mesh under the IEEE 802.11 standard. HWMP+ enables the creation of a self-configuring and self-healing network, facilitating network expansion and maintenance.

2. Mesh configuration in MikroTik: To configure a Mesh network on a MikroTik device, you need to use RouterOS, MikroTik's operating system.

The process includes configuring wireless interfaces to operate in Mesh mode, defining the routing protocol (such as HWMP+), and establishing the necessary parameters for the network.

3. Advantages of Mesh Networks:

• Flexibility and Scalability: Mesh networks allow you to easily add more devices without the need for additional cabling.
• Resilience: In a Mesh network, if one node fails, traffic can be automatically rerouted through other nodes, keeping the network operational without significant interruptions.
• Extended Coverage: By being able to place additional nodes that communicate with each other, Mesh networks are ideal for covering large and complicated areas where cabling would be impractical or too expensive.

4. Mesh applications in MikroTik: Mesh networks are especially useful in applications such as:

• Business environments and large campuses: Where extensive wireless coverage is needed without interruptions.
• Smart cities and communities: Where access points are distributed over large areas.
• temporary events: Such as festivals or fairs, where a robust and flexible network needs to be temporarily deployed.

Considerations

When setting up a Mesh network with MikroTik devices, it is crucial to ensure that all devices support the chosen Mesh protocol and are configured with compatible parameters.

Additionally, network design must consider node density, topology, and potential physical obstacles to optimize network performance and reliability.

Mesh networks are a powerful solution for many network scenarios, offering flexibility, scalability and resilience where traditional network deployment would be limited or costly.
