Microwave Ovens; Range - Proxim RangeLAN2 752 Series Manual

Microwave Ovens

Microwave ovens operate in the same frequency band as
RangeLAN2. Therefore, if you use a microwave within range of
RangeLAN2 you may notice network performance degradation.
However, both your microwave and your RangeLAN2 network
will continue to function.

Range

Every environment is unique with different obstacles, barriers,
materials, etc. and, therefore, it is difficult to determine the exact
range that will be achieved without testing. The site survey tool
was developed to aid in this process. Additionally, Proxim has
developed some guidelines to estimate the range that users will
see when the product is installed in their facility, but there are no
hard and fast specifications.
Radio signals may reflect off obstacles or be absorbed by others
depending on their construction. For example, with two 100 mW
RangeLAN2 radios you may achieve up to 1000' in open space
outdoors where the two antennas are line of sight, meaning they
see each other with no obstacles. However, the same two units
will only achieve up to 500' of range when they have to travel
through the cubicles usually used in modern offices. If there are
office walls to penetrate, the signal range may decrease even
further to up to 300'.
Proper antenna placement can help improve RangeLAN2 perfor-
mance. Try to place the antenna so that it extends above the top
of the computer.
