Your router is a radio transmier and receiver. It is designed
and manufactured not to exceed the emission limits for
exposure to radiofrequency (RF) energy. These limits are part
of comprehensive guidelines and establish permied levels of
RF energy for the general populaon. The guidelines are based
on standards that were developed by independent scienc
organizaons through periodic and thorough evaluaon of
scienc studies. These guidelines include a substanal safety
margin designed to ensure the safety of all persons, regardless
of age and health.
The exposure standard for routers employs a unit of
measurement known as the Specic Absorpon Rate, or SAR.
The SAR limit set by public authories such as the Federal
Communicaons Commission of the US Government (FCC), or
by Industry Canada, is 1.6 W/kg averaged over 1 gram of body
ssue. Tests for SAR are conducted using standard operang
posions with the router transming at its highest cered
power level in all tested frequency bands.
Although the SAR is determined at the highest cered power
level, the actual SAR level of the router while operang can
be well below the maximum value. This is because the router
is designed to operate at mulple power levels so as to use
only the power required to reach the network. In general, the
closer you are to a wireless base staon antenna, the lower the
power output of the router. Before a router model is available
for sale to the public, compliance with naonal regulaons and
standards must be shown.
The highest SAR value for this model router when tested is
0.97 W/Kg for use close to the body.
While there may be dierences between the SAR levels of
various routers and at various posions, they all meet the
government requirement for RF exposure. For body-worn
operaon, the router meets FCC RF exposure guidelines
provided that it is used with a non-metallic accessory with the
handset at least 10 mm from the body. Use of other accessories
may not ensure compliance with FCC RF exposure guidelines.
