The wireless protocols ( 802.11 & nstream & nv2 ) each have their advantages.
802.11 ;PROs , compatibility with just about everything
802.11 ; PROs , great for point-to-point Mikrotik WDS links and probable the fastest protocol for point-to-point ( one AP and one client )
802.11 ; CONs , horrible throughput in noisy environments. Example a mountian top AP with 30 far-distant clients where there is rouge noise every where
802.11 ; PRO and CON , prior to sending the transmitter needs to first listen and make sure the channel is clear ( if the channel is not clear then it waits ). This waiting can slow down all thorughput when there is an AP with many remote distant clients.
802.11 ; CONs , subject to over the air collisions which thus creates retries
nstream ; a polling protocol - The AP will tell each client when it can transmit. Solves some of the problems with 802.11
nv2 ; PROs , best for APs with many clients in noisy environments
nv2 ; PROs , no collisions between AP to clients and no collisions between any two clients transmitting at the same time
nv2 ; CONs , nv2 is a Mikrotik hybrid-custom TDMA protocol and is not compatible with non-Mikrotik devices
nv2 ; PROs , nv2 ( TDMA ) adjustable/tuneable time-slots can be tuned from a 50/50 ratio ( 50 percent of the time in AP transmit mode and 50 percent of the time in AP receive mode ). I normally use a 75.25 nv2 ( TDMA ) ratio where the AP is configured for 75 percent of the time to be in transmit mode and only use 25 percent of the time to receive. Almost all Internet clients receive ( download ) far more data than they send ( upload ). So for an AP with many nv2 clients , this works out well to allow more data to cutomers.
I have thousands of Mikrotiks in my networks and all of them are nv2 --- with the exception that I use 802.11 for point-to-point WDS links.
