7.2.4 Wifi analyzer
Wifi analyzer is an embedded application tool, to provide helpful information for the deployment and
Wifi configuration.
The IEEE802.11 a/g/n/ac standard makes use of a part of the 2.4GHz ISM band of the 5GHz U-NII
bands.
The 2.4GHz ISM band (industrial, scientific and medical) goes from 2.400 GHz to 2.500GHz and can
be used freely by any radio device for industrial, scientific and medical application. This band is also
used by several common telecommunications protocols or standards such as Wi-Fi, Bluetooth,
ZigBee, RFID devices … A more comprehensive list of systems authorized on this band can be found
at http://www.efis.dk/sitecontent.jsp?sitecontent=ecatable for the European Union and at
http://transition.fcc.gov/oet/spectrum/table/fcctable.pdf for the United States.
The 802.11 standard divides the 2.4GHz ISM band into thirteen 22MHz wide channels, spaced 5MHz
from each other (cf. as table 1 below). These channels strongly overlap with each other. The
availability of these channels varies from country to country.
Table 1 below depicts the channels enabled for the different regional versions
