En Joseph Bonicioli i companyia, que són d'una de les comunitats més actives fent xarxa que conec, l'AWMN i de la que ja n'he parlat alguna altra vegada, comparteixen amb nosaltres una informació molt interessant, i és que han conseguit fer enllaços que rendeixen 160 Mbits reals!. Ho han fet amb les "flautes" (son els feeders duals de les antenes que fan servir, i en diuen flautes per la forma, vegeu les fotografies a continuació, perquè son espectaculars) que ells mateixos es fabriquen,la beta del RouterOS 4.0, i 5GHz com a freqüència i wifi 802.11n com a protocol.

Fotografies de les flautes:

A aquestes flautes, les connecten a tarjes R52n (AR9220), tot i que em diuen que també funciona amb les AR5008 i AR5416 amb l'nstream activat.

Una configuració d'exemple:
