Two thoughts:

1. It´s designed for point-to-point, not point-to-multipoint.
In any case you´re thinking it wrong... this helps an ISP reach a new
target area -and cross over large unprofitable area (slims, parks)
without costly digging and laying out fibre-, then at the other end of
the airwaves, another of the Airfiber converts back to ethernet or
fibre and the backbone continues....

2. I´d say that at 24 Ghz it´s a quite narrow wavelength
http://www.convertunits.com/from/gigahertz/to/wavelengths+in+meters
0.012 meters = 1.2 cm, coupled with this unit´s directional antenna...
I don´t see interference as big of a problem as 2.4 Ghz with omnis...

Again, I´m sorry to sound like a Ubiquity salesman but I´m just too
excited that the 24 Ghz band is suddenly within reach of us mere
mortals for unlicensed use... this is better than the costly and
reach-limited Free Space Optics... a FSO Gigabit unit sells for $9900
* and only reaches about 1200 meters last time I looked ....
