11  Background
 (1) The meteorological-satellite service operates at frequencies below 1710 MHz, which is adjacent to the 1800 MHz lower band.
 (2) Earth receive stations in the meteorological-satellite service use the 1670 MHz to 1710 MHz frequency band for the reception of data to assist in meteorological forecasting and other scientific purposes. The service uses both geostationary (GSO) and non-geostationary (NGSO) space stations. The 1698 MHz to 1710 MHz frequency band is typically used for NGSO purposes, with GSO space stations deployed below 1698 MHz.
 (3) Out-of-band emissions from both fixed transmitters and mobile transmitters operated under an 1800 MHz spectrum licence have the potential to cause interference to earth receive stations in the meteorological-satellite service. The potential for interference is also likely to be increased for technologies that use wide-band emissions. The protection requirements in section 12 apply in relation to interference from all radiocommunications transmitters operated under an 1800 MHz spectrum licence, including mobile transmitters.
