Article 2
For the purposes of this Decision, the following definitions shall apply: (a) β79 GHz range radio spectrum bandβ shall mean the frequency range between 77 and 81 gigahertz; (b) βautomotive Short-Range Radar equipmentβ shall mean equipment providing road vehicle based radar functions for collision mitigation and traffic safety applications; (c) a βnon-interference and non-protected basisβ shall mean that no harmful interference may be caused to other users of the band and that no claim may be made for protection from harmful interference received from other systems or services operators operating in that band.
Article 3
The 79 GHz range radio spectrum band shall be designated and made available for automotive short-range radar equipment as soon as possible and no later than 1 January 2005, on a non-interference and non-protected basis. The maximum mean power density shall be of βΒ 3Β dBm/MHz effective isotropic radiated power (e.i.r.p.) associated with a peak limit of 55 dBm e.i.r.p. The maximum mean power density outside a vehicle resulting from the operation of one short-range radar shall not exceed βΒ 9 dBm/MHz e.i.r.p.
