The NV2 protocol (Nstreme version 2) is a wireless communication protocol developed by MikroTik that is specifically designed to improve the performance and stability of wireless networks, especially in environments where the level of interference is high and the density of nodes is considerable. This protocol may be a viable option for a WISP (Wireless Internet Service Provider) using MikroTik technology, particularly in environments with the following challenges:

Advantages of NV2

1. Improvement in Quality of Service (QoS): NV2 introduces a transmission time control mechanism that allows the allocation of specific time slots for each client, thus improving the quality of service by minimizing collisions and optimizing spectrum usage.
2. Better Interference Management: Since NV2 works with TDMA (Time Division Multiple Access), it reduces the interference typical of environments where multiple devices try to communicate at the same time, as is common in WISP scenarios.
3. Reduced Latency: Structured airtime management also helps reduce latency, which is crucial for applications that require real time, such as VoIP or online gaming.
4. Support for High Customer Density: NV2 is effective in scenarios where there are many clients connected to a single access point, helping to maintain consistent performance even under load.

Considerations When Using NV2

1. Compatibility: NV2 is only compatible with MikroTik equipment, which means that all devices on the network, both the access point and the clients, must be MikroTik.
2. Configuration and Optimization: NV2 configuration can be more complex than other standard protocols such as 802.11. Requires careful configuration and possibly frequent adjustments to optimize performance.
3. Performance in Different Environments: While NV2 is ideal for certain environments, in areas with lower client density or where interference is not a significant problem, other protocols may be simpler to manage and still offer adequate performance.

Recommendation

If you are operating a WISP with a high density of clients and facing significant interference and quality of service issues, NV2 is definitely recommended. However, it is important to ensure that all your equipment is compatible and be prepared to perform detailed network management.

For less dense environments or where configuration simplicity is a priority, it may be more effective to use standard 802.11-based protocols, along with spectrum optimization techniques and hardware improvements.

In conclusion, NV2 can be an excellent option for your WISP under the right conditions, offering significant improvements in performance and stability, but you should always consider the specific nature of your network and your operational needs before deciding on this protocol.
