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: +2 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 = 150 m.
Site sharing radius = 100 m.

Class 2 antenna.
Min. antenna gain = 40 dBi.
