Definition of spectral efficiency classes: refer to current version of EN 302 217-2 V3.2.2, clause 4.1.3.
Adaptive Modulation (ACM) is allowed.

10Additional essential requirements--
11Frequency planning assumptionsEN 302 217-2.
Nominal RX input level = - 50 dBm.
ATPC control range = min. 15 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 V3.2.2, clause 4.2.3.2, Figure 7.
=====
Allowed Reference Mode for ACM:
- 30 MHz / 40 MHz channelling with 128-QAM modulation.
=====
Min. link distance = 30 km.
Site sharing radius = 600 m.
=====
Class 3 antenna.
Min. antenna gain = 35 dBi.
Linear (horizontal or vertical) polarization.
Antenna radiation pattern envelope (RPE) according to current version of EN 302 217-4 V2.1.1, 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.
