Operating Environment

Always stop using the Site Survey Tool and disable the WLAN adapter when it is forbidden to use radio
equipment or when it may cause interference or danger.

User Training

User Training
The Site Survey Tool user should be appropriately trained and should be familiar with at least the basics
of signaling technology in Wireless LAN.

Term Definition
Wireless LAN Access Point.
Decibels relative to one milliwatt, where one
milliwatt (1 mW) equals 1/1000 of a watt. This
unit is commonly used in test laboratories to
define signal strength.
The dBm increment is based on the decibel, a
logarithmic measure of relative power. Suppose
a signal has a power level of P mW. Then the
signal strength in dBm, symbolized SdBm, is:
S = 10 log P
dBm 10
A 1-mW signal has a level of 0 dBm. Signals
weaker than 1 mW have negative dBm values;
signals stronger than 1 mW have positive dBm
values. The Site Survey Tool reports all signal
strengths as dBm values.

Wi-Fi (Wireless Fidelity) is the certification given
by the Wi-Fi Alliance for wireless networking
equipment that passes the Wi-Fi Alliance
stringent tests for adherence to IEEE 802.11
standards and for real-world interoperability.
Wi-Fi labeled equipment will work with any other
piece of wireless networking gear that also has
the Wi-Fi logo.
