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
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.
