916MHz in New Zealand

This one is for the New Zealand specialists. We make very low-power short
range telemetry devices that communicate on 916MHz outside of Europe. We
are getting interference reports from New Zealand, even though our
certification lab informed us that the band 915-921MHz band is reserved for
3mW maximum telemetry/telecommand overthere.

Has New Zealand legislation on this band changed recently or is this still
valid and should we look elsewhere?

Thanks,
Clemens

Hi Clemens, It's not an area where I have expertise but spectrum usage
is searchable at

<http://spectrumonline.med.govt.nz/licence-search.html>

The licences in that part of the spectrum seem to be for links between
commercial radio studios and their transmitter sites. Clicking on the
links at the left of the table will give details of the transmission.

The homepage at

<http://spectrumonline.med.govt.nz/>

has an email contact link at the bottom of the page if you want to
contact the spectrum management people.

Clemens.

You are almost cerainly operating under the General User Radio Licence
for Short Range Devices. As you note, you are permitted to use 3mW
eirp over the range 915-921 MHz. That legislation is current, but it's
on a shared basis, see notes 3 and 4 at
http://www.rsm.govt.nz/licensing/gurls/gurl-srd.html

===================================================
3. Frequency use is on a shared basis and the chief executive does
not accept liability under any circumstances for any loss or damage of
any kind occasioned by the unavailability of frequencies or
interference to reception.
4. Should interference occur to services licensed pursuant to a
radio licence or a spectrum licence, the chief executive reserves the
right to require and ensure that any transmission pursuant to this
general user radio licence change frequency, reduce power or cease
operation.
================================================

So, If you experience interference you have to accept it, or reduce
the effects by some means, maybe shifting freq, relocation, different
antennas, polarisation, shielding, or if all else fails: black magic?!
One thing that maybe possible is to shift to 921-929 MHz, where you
are permitted to use 1000mW eirp.

HTH,
