| 2 | Application | Point-to-Point | CCDP (Co-Channel Dual Polarization) ACCP (Adjacent Channel Co-Polarization) |
| 3 | Frequency band | A: 27.9405 - 28.4445 GHz B: 28.9485 - 29.4525 GHz | - |
| 4 | Channelling | 28 MHz / 56 MHz / 112 MHz | Channel centre frequencies according to REC T/R 13-02, Annex C. |
| 5 | Modulation / Occupied bandwidth | Class: min. 4L. (16-QAM or equivalent). ACM is allowed. OBW: 28 / 56 / 112 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 4L (16-QAM or equivalent): 28 MHz / 56 MHz with or without ACM. 112 MHz in particularly justified cases with ACM. |
| 6 | Direction / Separation | 1008 MHz | FDD |
| 7 | Transmit power / Power density | Max. 40 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 = - 40 dBm. ATPC control range = min. 10 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. ===== Allowed Reference Modes for ACM: - 28 / 56 / 112 MHz channelling with 16-QAM modulation. ===== Min. link distance = 2 km outside polygon ''Alpensüdseite''. Min. link distance = 1.5 km inside the poly-gon ''Alpensüdseite''. Polygon ''Alpensüdseite'' LV95 coordinates (CH1903+): 2721311/1072434; 2638386/1114490; 2680819/1156635; 2716723/1158677; 2782207/1137380. Site sharing radius = 200 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 25. 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). |
