Active Antennas...

[John Watlington]

There are no health concerns with the AAs.   Those modules have  
passed SAR
(Specific Absorption Rate) tests to both FCC and EU standards.

Martin was referring to the RF spectrum usage, which is higher for a  
given payload
using the mesh than when using a conventional AP.
