Note: Table 11 shows examples for the specified typical antennas. As
the antenna field distributions will differ, complete calculations or
measurements may be necessary to establish the compliance
boundary for other configurations chosen by the customer. For further
information on calculation methods, see document Radio frequency
electromagnetic fields, RBS 2000 and RBS 3000, guidelines, Safety
information, EN /LZT 720 0399.
Note: The expanded uncertainty (k=2) is ±2 dB for the underlying calculations
of the power density used for assessment of the compliance boundary
dimensions listed in Table 11.
Note: The combined configuration can be achieved with an external EHCU.
Characteristics of the antennas recommended for typical RBS configurations
with the RBS 2111 Second Generation are listed in Table 12.
