For a WISP (Wireless Internet Service Provider) that handles 200 clients and needs to implement client control using Queue Tree for bandwidth management, it is important to choose a MikroTik device that offers high performance, good processing capacity and sufficient connectivity options .

We recommend some MikroTik models that could be suitable for this purpose:

1. MikroTik Cloud Core Router (CCR) Series:
   • Model: CCR1009-7G-1C-1S+
     • This router is powerful and versatile, with 7 Gigabit Ethernet ports, 1 combo port (Gigabit Ethernet/SFP) and 1 SFP+ port. It has a 9-core Tilera processor that can handle high traffic loads, which is ideal for a WISP. Its ability to manage multiple data streams simultaneously makes it an excellent choice for managing Queue Trees.
   • Model: CCR1036-12G-4S
     • This model is even more powerful, with 36 CPU cores, providing outstanding capabilities for processing and managing traffic on larger networks. It has 12 Gigabit Ethernet ports and 4 SFP ports, thus offering excellent flexibility in terms of connectivity.
2. MikroTik RouterBOARD RB1100AHx4
   • This device offers excellent performance with its Annapurna Alpine AL21400 quad-core 1.4 GHz CPU and 13 Gigabit Ethernet ports. It is suitable for WISPs that need a robust solution to manage traffic and bandwidth effectively, and is capable of handling Queue Trees without problems.
3. MikroTik RouterBOARD RB4011
   • The RB4011 is a cheaper but equally effective option for smaller WISPs. It comes with a 10-core processor and offers 10 Gigabit Ethernet ports. It does not have the same level of performance as the CCR models, but is still suitable for a network of up to 200 clients, depending on specific traffic demands.

When choosing equipment for a WISP, it is essential to also consider aspects such as future scalability, security capabilities and ease of management through RouterOS, MikroTik's operating system.

These devices not only allow you to efficiently manage bandwidth through Queue Trees, but also offer advanced routing, firewall, VPN, and more capabilities, allowing you to provide high-quality service to your customers.
