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'.
