Other installation configurations or antennas can result in different compliance distances.
For characteristics of an antenna recommended for typical configurations of
an RBS 2106, see Table 5.
Table 5 Characteristics for a typical antenna (KRE 101 1916/1)
Antenna specifications X-pol macro RBS sector antenna
Antenna height 1.3 m
Half-power beam width 60 degrees
Antenna gain 14.5 dBi at 900 MHz, 17 dBi at 1800 MHz
The maximum power fed to the antenna, as a function of the number of
transceiver units (TRUs) per antenna and the maximum power (including
tolerances and transmission loss) per TRU, for RBS 2106 at 900 MHz and
1800 MHz, are given in Table 6.
