10. Performance Hints
This section provides ideas for how to increase performance with
Proxim wireless products.
Microwave Ovens
Microwave ovens operate in the same frequency band as
RangeLAN2. Therefore, if you use a microwave within range of
RangeLAN2 products, 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. Proxim has devel-
oped some guidelines to estimate the range that users will see
when the RangeLAN2 7920 Ethernet Adapter is installed in their
facility, but there are no hard and fast specifications. Note that the
RangeLAN2 7921 Ethernet Adapter will have greater range.
Radio signals may reflect off of some obstacles or be absorbed by
others depending on their construction. For example, with two
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'.
