1.4 Wireless Performance
The following information will help you utilizing the wireless performance, and operating coverage of
WRT-416.
1. Site selection
To avoid interferences, please locate WRT-416 and wireless clients away from transformers, microwave
ovens, heavy-duty motors, refrigerators, fluorescent lights, and other industrial equipments. Keep the
number of walls, or ceilings between AP and clients as few as possible; otherwise the signal strength
may be seriously reduced. Place WRT-416 in open space or add additional Access Point as needed to
improve the coverage.
2. Environmental factors
The wireless network is easily affected by many environmental factors. Every environment is unique
with different obstacles, construction materials, weather, etc. It is hard to determine the exact operating
range of WRT-416 in a specific location without testing.
3. Antenna adjustment
The bundled antenna of WRT-416 is adjustable. Firstly install the antenna pointing straight up, then
smoothly adjust it if the radio signal strength is poor. But the signal reception is definitely weak in some
certain areas, such as location right down the antenna.
Moreover, the original antenna of WRT-416 can be replaced with other external antennas to extend the
coverage. Please check the specification of the antenna you want to use, and make sure it can be used
on WRT-416.
4. WLAN type
If WRT-416 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 WRT-416 can operate in 11g-only mode, then its data rate should actually 54Mbps
