 <title>RF Behavior</title>
 			<para>
-				This section...
+				This section describes some of the natural behaviors of wireless or radio frequency (RF) signals. These behaviors can cause a loss of signal or other negative effects on your reception, speed, and general network performance. Knowing what they are, why they happen, and what environmental situations can cause them, is important when you are designing a network layout or troubleshooting your connection.

 <title>Reflection</title>
 			<para>
-				Reflection
+				Reflection occurs when a signal bounces off an obstacle. This can happen when hard surfaces such as walls or desks are in the wireless coverage area. ...[picture]

 <section id="sect-Wireless_Guide-Communication-RF_Behavior-Absorption">
 <title>Absorption</title>
 			<para>
-				Absorption
+				Absorption occurs when a signal is completely or partially absorbed when it travels into or through a medium, such as a wall. The level of absorption depends on the medium - for instance, brick or concrete walls will absorb signals more than a plaster wall. The result of absorption is lowered signal power, or amplitude. ...[picture]

 <section id="sect-Wireless_Guide-Communication-RF_Behavior-Refraction">
 <title>Refraction</title>
 			<para>
-				Refraction
+				Not to be confused with reflection, refraction occurs when a wireless signal is bent as it passes through an object, such as glass or water. As a way to understand refraction, consider what you see when you look at your reflection in a swimming pool. Your reflection may appear stretched or compressed. This happens to wireless signals in a similar way and can cause signal degradation. ...[picture]

 <title>Scattering</title>
 			<para>
-				Scattering
+				Scattering occurs when a signal hits an object that has several different edges or angles and bounces off it into multiple directions. Objects that can cause scattering may include a disco ball, a tree or other foliage, or window blinds. ...[picture]

 <section id="sect-Wireless_Guide-Communication-RF_Behavior-Diffraction">
 <title>Diffraction</title>
 			<para>
-				Diffraction
+				Diffraction is when a signal bends around an object and changes the path and direction of the signal. It often occurs when a signal hits small or sharp-edged objects.
