If I was there I would like to ask if I was at MUM meeting in Poland:
How to make wireless QoS with Mikrotik?
Correct me if I'm wrong, but there can't be real QoS on any wireless network, as there is on wired networks.
On wired networks you give some protocols the percentage of maximum bandwidth;
ie. http gets 30-90% (and is in 1st category)
ftp gets 40-60% (and is in 2nd category)
all rest gets 30-50% (and is in 3rd category)
so http ALWAYS gets minimum 30Mbit (30% of 100Mbit) on a standard network, and it is guaranteed to get that, there is no way it can get less than that, as ftp has a maximum of 40Mbit and all rest has 30Mbit, so combined it is 100Mbits/sec.
On a wireless network maximum bandwidth is always changing. If some client with poor connection connects speed throughput drops to everyone other connected. Also there is some overhead when there are more clients connected. It is not the same if there is only 2-3 clients connected or if there are 10, and not only because the speed is divided among the connected users but also because of the overhead and mutual noise that gets generated as more people put their antennas toward one to which they all connect.
Please correct me if I'm wrong and tell me how do you setup QoS on Mikrotik Wireless routers?
