| 4 | Channelling | 250 MHz / 500 / 1000 MHz. | 19 paired channels of 250 MHz, to form paired channels up to an channel bandwidth of 1000 MHz. Channel centre frequencies according to ECC/REC/(05)07, Figure A4.2. |
| 5 | Modulation / Occupied bandwidth | Class: 2 and 4L (QPSK and 16-QAM or equivalent). ACM is allowed. OBW: 250 / 500 / 1000 MHz. | Definition of spectral efficiency classes: refer to EN 302 217-2, clause 4.1.1.3. Adaptive Coded Modulation (ACM) and Adaptive Bandwidth is allowed.- OBW with Class 2 (QPSK or equivalent): 250 MHz / 500 MHz without ACM. OBW with Class 4L (16-QAM or equivalent): 250 MHz / 500 MHz with or without ACM. 1000 MHz in particularly justified cases with ACM. |
| 6 | Direction / Separation | 10 GHz | FDD |
| 7 | Transmit power / Power density | Max. 55 dBW e.i.r.p. for antenna gain of min. 55 dBi. | The max. e.i.r.p. has to be reduced, if the antenna gain is lower than 55 dBi. Refer to EN 302 217-3, Annex UC.2. 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: +2 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. ===== Limits of transmitter power spectral density: Refer to EN 302 217-2, clause 4.2.3.2, Figure 8. ===== Allowed Reference Modes for ACM and Adaptive Bandwidth: - 250 / 500 / 1000 MHz channelling with 16-QAM or equivalent modulation. ===== Min. link distance = 100 m. ===== Site sharing radius = 50 m ===== Class 3 antenna. Minimum antenna gain = 38 dBi. Linear (horizontal or vertical) polarization. Antenna radiation pattern envelope (RPE) according to EN 302 217-4, Figure 39. 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). |
