About the Firebox X Edge e-Series Wireless
The Firebox X Edge e-Series Wireless conforms to IEEE 802.11g/
b wireless LAN standards. Some key features that have an
effect on performance of an 802.11g/b wireless device include
antenna directional gain, signal attenuation (path loss), and
channel data rate.
Antenna directional gain
Antenna directional gain is based on the shape of the radiation
pattern around the antenna. The Firebox X Edge e-Series Wire-
less uses two 5.1 dBi swivel-mount whip antennas. The whip
antenna has a radiation pattern similar to a sphere that is
squashed in the center. If the antenna points up, the gain is
largest in the horizontal direction and less in the vertical direc-
tion.
