12. Performance Hints

This section provides the user with ideas as to how to increase performance and network
satisfaction on a wireless network.

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. Note that the RangeLAN2
7521 Access Point will have a longer range than the 7510 or the 7520.
Radio signals may reflect off of some obstacles or be absorbed by others depending on
their construction. For example, with two RangeLAN2 radios, using the standard
antennas shipped with the units, 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'.
There are many antenna options available for the RangeLAN2 Access Point. These
optional antennas offer additional range and different radiating patterns in order to
accommodate each user's wireless coverage needs. If you are interested in antenna
options, contact your Proxim Sales Representative about antenna kits. Note that due to
U.S. regulatory laws, antennas whose gain is rated higher than 9 dBi may not be used
with the RangeLAN2 7521 Access Point within the United States. Contact your Proxim
Sales Representative to obtain regulatory information for regions outside of the United
States.
