few as possible; otherwise the signal strength may be seriously reduced. Place PRT-
301W in open space to improve the coverage.
2. Environmental factors
The wireless network is easily affected by many environmental factors. Every environ-
ment is unique with different obstacles, construction materials, weather, etc. It is hard to
determine the exact operating range of PRT-301W in a specific location without testing.
3. Antenna adjustment
The bundled antenna of PRT-301W is adjustable. Firstly install the antenna pointing
straight up, then smoothly adjust it if the radio signal strength is poor. But the signal re-
ception is definitely weak in some certain areas, such as location right down the antenna.
Moreover, the original antenna of PRT-301W can be replaced with other external anten-
nas to extend the coverage. Please check the specification of the antenna you want to
use, and make sure it can be used on PRT-301W.
4. WLAN type
If PRT-301W is installed in an 802.11b and 802.11g mixed WLAN, its performance will
reduced significantly. Because every 802.11g OFDM packet needs to be preceded by an
RTS-CTS or CTS packet exchange that can be recognized by legacy 802.11b devices.
This additional overhead lowers the speed. If there are no 802.11b devices connected, or
if connections to all 802.11b devices are denied so that PRT-301W can operate in 11g-
only mode, then its data rate should actually 54Mbps.
