4Channelling250 kHz / 500 kHz-
5Modulation / Occupied bandwidthAnalogue modulation, equivalent to class 4L.
OBW: 250 / 500 kHz.		Definition of spectral efficiency classes: refer to EN 302 217-2, clause 4.1.1.3.
Equipment with analogue modulation shall operate within the spectrum mask of class 4L equipment.
6Direction / Separation-Unidirectional
7Transmit power / Power densityMax. 35 dBW e.i.r.p.The operational e.i.r.p. will be specified in the license / individual assignment.
8Channel access and occupation rules--
9Authorisation regimeSwitzerland: License required.
Liechtenstein: Individual assignment required.		-
10Additional essential requirements--
11Frequency planning assumptionsEN 302 217-2.
Nominal RX input level = - 50 dBm.
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,
- Propagation: clear sky conditions (i.e. without rain fading).
=====
Limits of transmitter power spectral density: Refer to EN 302 217-2, clause 4.2.3.2, Figure 7.
=====
Min. link distance = 20 km.
Site sharing radius = 150 m.
=====
Class 2 antenna.
Min. antenna gain = 23 dBi.
Linear (horizontal or vertical) polarization.
Antenna radiation pattern envelope (RPE) according to EN 302 217-4, Figure 9.
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.
