2.11.2 8580/8590 Antenna Solutions for EU Countries
The integrated 8580/8590 antenna solutions are based on the prevailing
IEEE.802.11b standard, which allows wireless data transfer at rates from 54 Mbps
to 1 Mbps using the 2.4 GHz band.
Warning: According to regulations published in the gazette 89/2003 of the
RegTP (regulating body for telecommunications and mail), now:
Federal network agency for electricity, gas, telecommunications,
post and railway the maximum permissible transmitting power,
EIRP (equivalent isotropically radiated power), in the 2.4 GHz fre-
quency band is set at 20 dBm.
The transmitting power of the two integrated antennas (4 dBi or
5 dBi) must be set to 30 mW (15 dBm) so that the EIRP limit value
is adhered to when using the antenna.
