8 Selecting channels
For a working installation an ESL channel must be selected on each ESL access point in the network.
There are 11 non overlapping ESL channels reserved for the communication with the labels. Five of
these ESL channels do not interfere with typical Wi-Fi installations and should therefore be favored.
These are the ESL channels 3, 5, 8, 9 and 10 and they should be selected if there is a Wi-Fi
installation on the Wi-Fi channels 1, 6 and 11.
FIGURE 1-16: Comparison between common used Wi-Fi and ESLchannels
If there is a Wi-Fi installation operating at 2.4 GHz (IEEE 802.11 b/g/n) or any other radio frequency
(RF) technology that uses the 2.4 GHz ISM band make sure to select the ESL channels that are least
overlapping with the existing installation. If there is no ESL channel without any overlapping both the
ESL and existing installation should still work but there might be a reduced overall speed in both
installations.
Warning: Do not select the same ESL channel on two access points within one area. This will cause
interferences and avoids labels from joining the network or being updated. The same ESL channel
may only be selected on two access points if it can be guaranteed that every label is within the range
of only one of these access points.
