| 2 | Application | Point-to-Point | CCDP (Co-Channel Dual Polarization) ACCP (Adjacent Channel Co-Polarization) |
| 3 | Frequency band | A: 51.400 - 51.944 GHz B: 52.056 - 52.600 GHz | - |
| 4 | Channelling | 7.0 MHz / 14.0 MHz / 28.0 MHz | Channel centre frequencies according to CEPT/ERC/REC 12-11. |
| 5 | Modulation / Occupied bandwidth | Class: 2 and 4L (QPSK and 16-QAM or equivalent). ACM is allowed. OBW: 7.0 / 14.0 / 28.0 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): 7.0 MHz / 14.0 MHz / 28.0 MHz without ACM. OBW with Class 4L (16-QAM or equivalent): 7.0 MHz / 14 MHz without ACM. OBW with Class 4L (16-QAM or equivalent): 28.0 MHz with or without ACM. |

| 11 | Frequency planning assumptions | EN 302 217-2. Nominal RX input level = - 50 dBm. ATPC is an optional feature, 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: +2 to -10 dB, - Propagation: clear sky conditions (i.e. without rain fading). - ATPC set to min. TX output power in clear sky conditions. ===== 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 Mode for ACM: - 28.0 MHz channeling with 16-QAM modulation. ===== Min. link distance = 150 m. Site sharing radius = 100 m. ===== Class 2 and 3a antenna. Min. antenna gain = 40 dBi. Linear (horizontal or vertical) polarization. Antenna radiation pattern envelope (RPE) according to EN 302 217-4, Figure 34 and Figure 35. 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. |
