| 2 | Application | Point-to-Point | CCDP (Co-Channel Dual Polarization) for 28 MHz and 56 MHz. ACCP (Adjacent Channel Co-Polarization) for 56 MHz only. |
| 3 | Frequency band | A: 24.549 - 25.445 GHz B: 25.557 - 26.453 GHz | - |
| 4 | Channelling | 28.0 MHz / 56.0 MHz | Channel centre frequencies according to REC T/R 13-02, Annex B. |
| 5 | Modulation / Occupied bandwidth | Class: 5HB and 6LB (128-QAM and 256-QAM or equivalent). ACM is allowed. OBW: 28.0 MHz / 56.0 MHz. | Definition of spectral efficiency classes: refer to EN 302 217-2, clause 4.1.1.3. Limits for the occupied bandwidth: refer to EN 302 217-2, clause 4.2.3.2, unified spectrum masks, Figure 7. Adaptive Coded Modulation (ACM) is allowed. OBW with Class 5HB (128-QAM or equivalent): 28.0 MHz with or without ACM only for CCDP. OBW with Class 5HB (128-QAM or equivalent): 56.0 MHz with or without ACM. OBW with Class 6LB (256-QAM or equivalent): 28.0 MHz / 56.0 MHz without ACM. |

| 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, unified spectrum masks, Figure 7. ===== Allowed Reference Modes for ACM: - 28.0 MHz channelling with 128-QAM modulation, - 56.0 MHz channelling with 128-QAM modulation. ===== Min. link distance = 2 km. Site sharing radius = 200 m. ===== Class 3 antenna. Min. antenna gain = 40 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). |
