Wireless signals are carried by electromagnetic
waves in the Radio Frequency (RF) bands. The
frequency range used by the Essential Insight.mesh
802.15.4 wireless mesh network is 2.4 GHz–2.4835
GHz. The typical node to node communication range
is 50–75 m (165–246 ft), occasionally achieving paths
of 100 m (330 ft) and greater in outdoor, line of site
applications.

passing through obstacles is important when

Repeaters in a wireless mesh network.
When a wireless signal meets an obstacle in its path,
a combination of events can occur. Some of the
signal may pass through the object, some may be
absorbed by the object, or some may be subjected to
reflection, diffraction, or scattering.

Absorption - Certain insulating materials, such as
concrete, water, or ceramics can absorb
electromagnetic energy by converting it to heat.
