● What construction materials are used in wall and floors?
Users are dropped from the wireless network
Suggested causes and solutions:
● Find out if a person or workgroup moved or if the building has been rearranged.
● If two or more users are seated too close to each other, performance can suffer.
Instruct your users to space themselves a small distance apart to keep receivers
from being overloaded.
● Delivery trucks with very large metal sides can affect performance by reflecting
destructive signals back into a building. If you have an installation that includes a
shipping dock, check to see if the problem coincides with the arrival of large
trucks.
● Personal “systems” can also interfere with your network. Wireless speakers,
cordless earphones, some Bluetooth devices, and similar systems can be the
source of an infrequent but hard to find the problem. Some systems do not conform
to wireless regulations. Shut off suspect devices or remove them from the area.
● If possible, remove and reinstall your new software. Conflicts with other resident
software packages are always a possibility, and they are not always the fault of the
newest addition. Sometimes just starting over fixes the problem.
● Swap units around. Does your problem follow the changed units, or is it unique to a
specific location? If it follows the product, the swapped unit could be damaged, or
improperly configured. If the problem stays with the location, try to find out what is
different about that particular room or area.
Range decreases as data rate increases
This is a normal condition. Range is inversely proportional to data rate: the faster the
data, the shorter the range. This has to do with the modulation technology used. Very
fast data rates require extremely complex signal waveforms, where even minor
distortions can result in data errors. Slower data rates are much more tolerant, and
consequently will get through even in the presence of some amount of noise,
interference, distortion and echo.
Signal doesn't pass through a short or thin wall
Range is highly dependent on the physical environment. In a line-of-sight location, with
elevated and calibrated antennas, range predictions are quite accurate. This is not true in
