Wi-Fi analyzer
The Wi-Fi analyzer is an embedded application tool which provides advice for the deployment and Wi-Fi
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 the likes of 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.
The table below depicts the channels enabled for the different regional versions:
