Each balloon can provide connectivity to a ground area about 40 km in
diameter at speeds comparable to 3G. For balloon-to-balloon and
balloon-to-ground communications, the balloons use antennas
equipped withspecialized radio frequency technology. Project
Loon currently uses ISM bands (specifically 2.4 and 5.8 GHz bands)
that are available for anyone to use.
