| 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: 10.150 - 10.300 GHz B: 10.500 - 10.650 GHz | - |
| 4 | Channelling | 7 / 14 / 28 MHz. | Channel centre frequencies according to CEPT/ERC/REC 12-05. |
| 5 | Modulation / Occupied bandwidth | Class: 2 and 4L (QPSK and 16-QAM or equivalent). ACM is allowed. OBW: 7 / 14 / 28 MHz. | Definition of spectral efficiency classes: refer to current version of EN 302 217-2 V3.3.1, clause 4.1.3. Adaptive Modulation (ACM) is allowed. OBW with Class 2 (QPSK): 7 MHz without ACM. OBW with Class 4L (16-QAM or equivalent): 7 MHz / 14 MHz with or without ACM. OBW with Class 4L (16-QAM or equivalent): 28 MHz in particularly justified cases with or without ACM. |
| 6 | Direction / Separation | 350 MHz | FDD |
| 7 | Transmit power / Power density | 10.15 - 10.6 GHz: max. 50 dBW e.i.r.p. 10.6 - 10.65 GHz: max. -3 dBW | The operational e.i.r.p. will be specified in the license / individual assignment. 10.6 - 10.65 GHz: max. transmitter power at the antenna port according to ECC/DEC/(10)01. |

| 10 | Additional essential requirements | - | - |
| 11 | Frequency planning assumptions | EN 302 217-2. Nominal RX input level = - 55 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 (current version of EN 302 217-1 V3.3.1, 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: - 7 / 14 / 28 MHz channelling with 16-QAM modulation. ===== Min. link distance = 15 km. Site sharing radius = 900 m. ===== Class 3 antenna. Min. antenna gain = 33 dBi. Linear (horizontal or vertical) polarization. Antenna radiation pattern envelope (RPE) according to EN 302 217-4, Figure 13. 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. ===== For 10.600 - 10.650 GHz max. elev. +20° |
