| 3 | Frequency band | A: 17.700 - 18.700 GHz B: 18.700 - 19.700 GHz | Assignments will be made in the frequency band segments: A1: 17.706875 to 17.961250 GHz B1: 18.716875 to 18.971250 GHz. |
| 4 | Channelling | 7.50 MHz / 13.75 MHz / 27.50 MHz. | Channel centre frequencies according to ITU-R Rec. F.595, Annex 4 (7.5 MHz channelling), CEPT/ERC/REC 12-03, Annex A (13.75 and 27.50 MHz channelling). |

OBW: 7.50 / 13.75 / 27.50 MHz | Definition of spectral efficiency classes: refer to EN 302 217-2, clause 4.1.1.3. Adaptive Coded Modulation (ACM) is allowed. OBW with Class 2 (QPSK): 7.50 MHz without ACM. OBW with Class 2 (QPSK): 13.75 MHz in particularly justified cases and without ACM. OBW with Class 4L (16-QAM or equivalent): 7.50 MHz / 13.75 MHz with or without ACM. OBW with Class 4L (16-QAM or equivalent): 27.50 MHz without ACM. |
| 6 | Direction / Separation | 1010 MHz | FDD |
| 7 | Transmit power / Power density | Max. 46 dBW e.i.r.p. | The operational e.i.r.p. will be specified in the license / individual assignment. |

| 11 | Frequency planning assumptions | EN 302 217-2. Nominal RX input level = - 55 dBm. ATPC control range = min. 12 dB to max. 20 dB. | Conditions for the nominal RX input level: - Receiver input, point A in the system block diagram (EN 302 217-1), - RX input level tolerance: +1 to -10 dB, - ATPC set to min. TX output power in clear sky conditions (i.e. without rain fading). ===== ATPC power increases shall be triggered on the basis of propagation effects only. The ATPC system shall not remain at max. available power (EN 302 217-1, clause 3.1) for more than 15 consecutive minutes (ITU-R Rec. F.750). ===== Remote Transmit Power Control (RTPC) is considered to be an optional feature. ===== At first CCDP has to be used and then ACCP. ===== Limits of transmitter power spectral density: Refer to EN 302 217-2, clause 4.2.3.2, Figure 7. (7.5 MHz channelling: Limits for 7.0 MHz channelling shall be applied) ===== Allowed Reference Modes for ACM: - 7.5 MHz channelling with 16-QAM modulation, - 13.75 MHz channelling with 16-QAM modulation. ===== Min. link distance = 8 km outside polygon ''Alpensüdseite''. Min. link distance = 4 km inside the polygon ''Alpensüdseite''. Polygon ''Alpensüdseite'' LV95 coordinates (CH1903+): 2721311/1072434; 2638386/1114490; 2680819/1156635; 2716723/1158677; 2782207/1137380. Site sharing radius = 400 m. ===== Class 3 antenna. Min. antenna gain = 36 dBi. Linear (horizontal or vertical) polarization. Antenna radiation pattern envelope (RPE) according to EN 302 217-4, Figure 17. OFCOM may impose tighter requirements than the minimum values given in EN 302 217-4 in order to maximize the use of the scarce spectrum resources (Class 4 antenna). |
