Hello,
I have a question regarding the compatibility of multicast-helper in a Point-to-Point scenario. I couldn’t find any references in the documentation specific to this scenario, nor any relevant posts in the forum.
If our other options aren’t feasible, we might need to establish a point-to-point wireless connection in a highly congested WiFi environment. Complicating matters, one end of the connection needs to be on a rotating stage. My plan is to use a NetMetal ax with an omnidirectional antenna at the center of the stage, and a directional antenna like the mANTbox ax 15s at the side. This setup should maintain a relatively static distance between the access point and station, with distances ranging from 12 to 15 meters. One requirement is to transport multicast data between these endpoints, which requires low jitter, although manufacturer specifications on acceptable jitter levels are not provided. Overall, this setup is far from ideal, and reliability may be a concern.
Regarding the WiFi connection itself, multicast transport over WiFi is challenging, but multicast-helper can convert multicast packets into unicast frames for each station to optimize airtime usage and avoid fallback to lower basic rates.
My question is whether multicast-helper functionality also applies to station-bridge mode access points. Does this conversion to unicast occur only at the physical layer, and once received at the station, does the packet appear as the original multicast packet and can be forwarded further? Or does multicast-helper not function in a station-bridge scenario, necessitating the use of Layer 2 tunnel technologies?
Thank you for your assistance.
Best regards,
