Antenna Overview
An ant enna couples RF signals ont o air. A t ransm it t er wit hin a wireless device sends an RF signal t o
t he ant enna, which propagat es t he signal t hrough t he air. The ant enna also operat es in reverse by
capt uring RF signals from t he air.
Posit ioning t he ant ennas properly increases t he range and coverage area of a wireless LAN.
Antenna Characteristics
Frequency
An ant enna in t he frequency of 2.4GHz ( I EEE 802.11b and I EEE 802.11g) or 5GHz ( I EEE 802.11a)
is needed t o com m unicat e efficient ly in a wireless LAN
Radiation Pattern
A radiat ion pat t ern is a diagram t hat allows you t o visualize t he shape of t he ant enna's coverage
area.
Antenna Gain
Ant enna gain, m easured in dB ( decibel) , is t he increase in coverage wit hin t he RF beam widt h.
Higher ant enna gain im proves t he range of t he signal for bet t er com m unicat ions.
For an indoor sit e, each 1 dB increase in ant enna gain result s in a range increase of approxim at ely
