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 MHz, for each bearing, σn.

      Note:                 For a device with an 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.

      LOP                :  is the level of protection. For radiocommunications transmitters that incorporate an AAS and are used specifically for beam-forming, the LOP is –92 dBm per MHz. For all other radiocommunications transmitters, the LOP is –100 dBm per MHz.

      Gr                 :  is the nominal radiocommunications receiver antenna gain, including feeder loss set to 0 dBi for the 700 MHz upper band, and 13 dBi for the 700 MHz lower band.

      PL(lmn,Lmn)        :  is the propagation loss (dB) (calculated under item 3 of this Schedule) of the mth increment on the nth radial.
