Chapter 4 - Wireless Performance
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. However, 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 of some obstacles or be absorbed by others
depending on their construction. For example, with two 802.11b radios,
you may achieve up to 1000' in open space outdoors where two devices
have a line of sight, meaning they see each other with no obstacles. However,
the same two units may only achieve up to 300' of range when used indoors.
The IEEE 802.11b specification supports four data rates: 11 Mbps, 5.5 Mbps,
2 Mbps, and 1 Mbps. Operation at 1 Mbps provides greater range than
operation at 11 Mbps. The SpaceLink 802.11g Access Pointwill
automatically adjust the data rate to maintain a usable radio connection.
Therefore, a client that is close to the SpaceLink 802.11g Access Pointmay
operate at 11 Mbps while a client that is on the fringe of coverage may
operate at 1 Mbps. As mentioned earlier, you can configure the data rates
that the SpaceLink 802.11g Access Pointwill use. Note that if you limit the
range of data rates available to the SpaceLink Dual-Band Home Gateway,
you may reduce the effective wireless range of the SpaceLink 802.11b
products.
