8  InstantWave  High Speed 

A characteristic of radio communication is the 

 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 Speed 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 Speed

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 Speed, resulting in
performance degradation on the wireless network

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)

InstantWave High Speed 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 Speed Station Monitor RF Signal

Quality Program

4.  Move the AP and the APs antenna to find the best signal quality

The AP may be either freestanding or wall-mounted.  Screws and a paper template
are provided for easy installation.
