Access Point Placement Guidelines
A characteristic of radio communication is the “interference” problem. Radio is
receptive to interference. Therefore, the more interference you can avoid, the
better performance you will get from wireless products. The following section
describes how the InstantWave High Rate AP should be placed to reduce possible
interference.
A few tips to mention that are particularly significant in a radio wave
communications system:
1. Radio waves reflect or refract from buildings, walls, metal furniture, or other
objects. This could result in performance degradation due to the fluctuation of
the received signal.
2. Microwave ovens use the 2.45 GHz frequency band. InstantWave High Rate
also functions in the 2.4 ~ 2.5 GHz band, and therefore shares some of the
band with microwave ovens. This means that when a nearby microwave oven
is in use, it may interfere with InstantWave High Rate, resulting in
performance degradation on the wireless network.
Placing For Performance
For the best performance, it is advisable that users follow the guidelines below in
placing the product:
• Place the AP as high as possible, in as open an area as possible
• Avoid placing the AP (especially the antenna) close to metal objects (e.g., file
cabinets, metal cubicles, etc.)
• Keep APs and Stations as far away as possible from microwave ovens (10
meters min. is advisable)
Placement Tools
InstantWave High Rate includes a Station utility program to help users find the
best location in which to place the AP relative to the location of the Stations.
1. Start the AP
2. Allow a wireless Station to connect with the AP
3. From the Station, run the InstantWave High Rate Station Monitor RF Signal
Quality Program
4. Move the AP and the AP’s antenna to find the best signal quality
Mounting the AP
The AP may be either freestanding or wall-mounted. Screws and a paper template
are provided for easy installation.
