WatchGuard Firebox SOHO 6 Wireless

OTE
Laptop computers typically have one antenna, which is more susceptible
to signal fading depending on position. This can lead to a situation where
the SOHO 6 Wireless hears the laptop’s signal, but the laptop doesn’t
hear the access point.
Antenna Directional Gain:
Antenna Gain is the result of how directional the radiation
(transmit/receive signal strength) pattern is. The higher the
gain, then the more directional the antenna is.
The SOHO 6 Wireless ships with 5dBi antennas. This
means they have a maximum 5 dBi gain pattern
perpendicular to the antenna position. A laptop computer
antenna gain will vary but might be as low as -10dBi for
embedded wireless antennas.
Transmitted Power:
SOHO 6 Wireless transmits at 15dBm (0.032 watts), which
is compatible with US and European and other
requirements. In the USA 802.11b devices may transmit at
up to (1 watt) and up to (0.1 watt) in Europe. Allocated
channels vary for USA and Europe.
Signal strength is a function, both of how much power was
transmitted, and how much power was received. This is impacted
by the antenna gain at the transmitter and receiver as well as the
distance and the environment in between them. Due principally to
the effect of cluttered environment, signal loss increases faster in
an office building than it would for line-of-sight transmission.
Channel Bandwidth:
This varies with the type of modulation scheme. 802.11b devices
use CCK (11 Mbps, 5.5 Mbps), DQPSK (2 Mbps), and DBPSK
