2 Device boundary criterion
The device boundary criterion is the value of the mathematical expression: RP – MP where:
| MP | : | is PL(lmn, Lmn) + LOP – Gr; |
|---|---|---|
| RP | : | is the horizontally radiated power, measured in dBm EIRP per 30 kHz, for each bearing, σn. |
| Note 1: | For a radiocommunications device with AAS, the RP at bearing σn is defined as the sum of the gain of the antenna towards the horizontal plane and towards azimuth σn (dB) and the total radiated power (dBm). This allowance is based on the assumption that beam pointing angles and/or power can be controlled dynamically to ensure RP is not exceeded. | |
| Note 2: | For RP for a group of radiocommunications transmitters, see subitem 1(2). | |
| LOP | : | is the level of protection. For radiocommunications transmitters that incorporate an AAS, the LOP is -107 dBm per 30 kHz. For all other radiocommunications transmitters, the LOP is -115 dBm per 30 kHz; |
| Gr | : | is the nominal radiocommunications receiver antenna gain, including feeder loss set to 0 dBi; |
| PL(lmn, Lmn) | : | is the propagation loss (dB) (calculated under item 3 of this Schedule) of the mth increment on the nth radial. |
