MikroTik

Greetings ..

I've heard that the 912 Lan capacity is 100 Mbps .. and I have a 912 with a 30 db dish and the readings of the approximately tx & rx is 120 - 180 Mbps

how come ??

2x2 mimo 802.11n is capable of 300Mbits airspeed under ideal conditions.

Think you are confusing the wireless sync speed to the ethernet lan speed.

Thank you for replay ..
I meant if you're saying that the airspeed is 300Mbits so can I get 300Mbits from the 912 LAN??

Hi .. 
are they not linked together on the same measurement units which is the Megabit?

No. It means that the RF modulation speed is 300Mbps, the actual throughput will be slower.
You will be able to get up to 100Mbps from the LAN to the radio.
And in the same time, if someone will use your radio as intermediate station (e.g. 2 clients connected to the same AP communicating with each other), they would still have some data bandwidth left. Or there could be another flow in the other direction, up to 100Mbps (Radio is simplex, ethernet is full duplex).
Anyway, you will never be able to get the full 300 Mbps from the radio to be used by a wired connection (even if you would have a Gbit port) because of rx/tx switching time, radio protocol, round trip and simplex mode limitations.

thank you very much

btw Rb912 has gigabit lan
