The antenna pattern representation for each beam type (MID and SIDE) are given on Figures 1A, 1B, and 2B for both vertical (at 0° azimuth) and horizontal (at elevation corresponding to the maximum gain, i.e. 45° (MID) and 55° (SIDE). 1A 1B 2A 2B 2.1.3 Protection criteria The relevant protection criteria is given in Table 3, taken from Recommendation ITU-R . Even if RLANs are nomadic/mobile by nature, their very high density implies that the interference will be systematic. The relevant percentage of data availability, corresponding to the percentage of time, is therefore 99% (see Document ) 3 Sensor type Interference criteria Data availability criteria (%) Performance degradation I/N (dB) Systematic Random Scatterometer 8% degradation in measurement of normalized radar backscatter to deduce wind speeds –5 99 95 For the SCA instrument, the protection criteria calculated over a 2 MHz bandwidth is –143 dBW (-113 dBm) not to be exceeded more than 1% of the time. This criteria is applied over data acquisition periods of time when the sensor is operating over the measurement area of interest (as per Recommendation ITU-R ). 2.2 Mobile service (WAS/RLAN) RLAN parameters used in the present studies are those agreed in the previous study period and given in the preliminary draft new Report ITU-R RS.[EESS RLAN 5 GHz] (see Annex 35 to Document 4-5-6-7/715 (Chairman’s Report)): – e.i.r.p. distribution:
