MIKROTIK RB911G-2HPND, Maximum speed possible

Just a quick basic question: what is the theoretical maximum that can be achieved with 2 of these boards, 21dbi antennae. Lets say at 100m, clear LOS. Thanks

Why 2,4Ghz? On 100m link you can use 60Ghz = 1Gbit troughput

Wireless specification.

300Mbps is the "interface rate" ! See http://mcsindex.com/ , yellow field, 40 MHz bandwidth (use only if you are alone there!), dual stream, MCS15, SGI=short guard interval of 0.4┬Ás)

Practical throughput could be 200Mbps for UDP, 150 Mbps for TCP. Overhead depends on the buffer size used.
Available airtime will not be 100% if other 2.4GHz devices are around. And also the quality (CCQ) will be reduced by noise and interference, what will make the devices lower the MCS rate used.

+1000

If you don't have buy any, buy 60GHz... less size, more speed...

Thanks All, esp Bpwl.
