Wireless repeaters
In addition to the wireless bridge function,
Nokia access points can act as wireless
repeaters, and extend the range of a system by
receiving and re-transmitting the data at a
mid-point in the communication path:
In the example above, the data from LAN A
which needs to be sent to LAN B is first sent to
the repeater. It is then re-transmitted from the
repeater to LAN B.
Note: Data rate does become degraded, the
more repeaters you use:
degradation of data rate = data rate /
(number of repeaters + 1)
Examples
• For one repeater the data rate is halved.
• For two repeaters, the data rate is divided by
three, and so on.
