Multi-Channel Operation; Figure 2.2. Multi-Channel Operation - Contec FX-DS110-APL User Manual

Overview

Multi-channel Operation

By changing channels on adjacent access points, it is possible to
obtain higher throughput per wireless terminal than when is
channels are not changed, even when the number of wireless
terminals is increased.
The 2.4G ISH band (2400 to 2483.5 MHz) in which this product
operates is subdivided into 11 (FCC model) or 13 (CE model)
channels, numbered 1 to 11 or 13, by IEEE standard 802.11.
Because each frequency has sidebands around its central frequency,
sidebands on adjacent channels overlap. Overlapping frequencies
can adversely affect communications by interference with each
other's transmissions.
Refer to Figure 2.3 when selecting channels, to ensure that
frequency bands do not overlap.
The maximum number of channels that can be used simultaneously
without interference is four, by using a combination of channels 1, 6,
11. Channel numbers can be set from 1 to 11 using utility
software.
Two wireless terminals on the same network cannot use the same
frequency.
