Google Project Loon interference concerns

Concerns have been raised about interference from the 2400 MHz and
5800 MHz transmitters on the Google Project Loon High Altitude
Balloons.

Google has launched 30 balloons from New Zealand which transmit
wideband 2400 MHz and 5800 MHz signals and concerns have been raised
about the interference they could cause to radio astronomy.

The Register reports that when Google engneer Dr Brad Tucker was
contacted about the problem, Google said they had identified locations
where Loon balloons might interfere with radio astronomy, and shut the
transmitters down until they're out of range.

Google plans to sending up 300 balloons around the world at the
southern fortieth parallel that would provide coverage to New Zealand,
Australia, Chile, and Argentina.

The company hopes to eventually have thousands of balloons flying in
the stratosphere at an altitude of 20 km.

The Amateur and Amateur Satellite Services also use the frequencies
that Project Loon is transmitting on.
