| Nr | Parameter2) | Description | Comments |
| 1 | Radiocommunication service | Fixed | - |
| 2 | Application | Point-to-Point | CCDP (Co-Channel Dual Polarization) ACCP (Adjacent Channel Co-Polarization) |
| 3 | Frequency band | A: 41.000 - 42.000 GHz B: 42.500 - 43.500 GHz | - |
| 4 | Channelling | 28 MHz / 56 MHz / 112 MHz | Channel centre frequencies according to ERC/REC/(01)04, recommends 2 (Annex 5) and recommends 4 (Annex 6, option A). |
| 5 | Modulation / Occupied bandwidth | Class: 4L (16-QAM or higher). ACM is allowed. OBW: 28 / 56 / 112 MHz. | Definition of spectral efficiency classes: refer to current version of EN 302 217-2 V3.3.1, clause 4.1.3. Limits for the spectrum masks: refer to current version of EN 302 217-2 V3.3.1, clause 4.2.3.2, Figure 7. Adaptive Coded Modulation (ACM) is allowed. OBW with Class 4L (16-QAM or higher): 28 MHz / 56 MHz with or without ACM. 112 MHz in particularly justified cases with or without ACM. |
| 6 | Direction / Separation | 1500 MHz | FDD |
| 7 | Transmit power / Power density | Max. 50 dBW e.i.r.p.. | The operational e.i.r.p. will be specified in the license / individual assignment. |
| 8 | Channel access and occupation rules | - | - |
| 9 | Authorisation regime | Switzerland: License required. Liechtenstein: Individual assignment required. | - |
| 10 | Additional essential requirements | - | - |
| 11 | Frequency planning assumptions | EN 302 217-2. 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 for the spectrum masks: refer to current version of EN 302 217-2 V3.3.1, clause 4.2.3.2, Figure 7. ===== Allowed Reference Modes for ACM: - 28.0 MHz channelling with 16-QAM modulation, - 56.0 MHz channelling with 16-QAM modulation. ===== Min. link distance = 500 m. Site sharing radius = 150 m. ===== Class 3A, 3B, 3C antenna. Min. antenna gain = 38 dBi. Linear (horizontal or vertical) polarization. Antenna radiation pattern envelope (RPE) according to EN 302 217-4, Figure 29, 30, 31. 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). |
