performance. As a result, neighboring

cells each have their own medium and the delays resulting from time-offset

transmission no longer occur.

Channel spacing should be as large as possible; a practical value would be 25

MHz. Even in a multichannel configuration, all SCALANCE W78x access points

can be configured with the same network name.

Multichannel Configuration

If neighboring SCALANCE W78x access points use the same frequency cha

the response times are longer due to the collisions that occur. If the configuration

shown in Figure 1-4 is implemented as a single-channel system, computers A a

B cannot communicate at the same time with the SCALANCE W78x access po

in their ce

If neighboring SCALANCE W78x access points are set up for different frequencies,

this leads to a considerable improvement in
