Introduction
Antennas
The SOMAport receives radio signals from and transmits radio signals to a
basestation operated by your wireless service provider. The basestation consists of
a tower and an equipment box that houses the radio transmitters and receivers
that allow the tower to communicate with the SOMAport.
The internal antenna
The SOMAport is essentially a two-way radio with an antenna inside. You don’t
have to aim this antenna yourself. The antenna tunes itself when you plug in the
SOMAport. The SOMAport also periodically checks whether or not the current
antenna direction is optimal. If it is not, the SOMAport automatically adjusts the
antenna direction. This means that if you move the SOMAport without
unplugging it first and the antenna direction is no longer optimal for the new
location, the SOMAport will automatically resteer the antenna to improve
performance.
SOMAport performance can be affected by the strength of the wireless signal it
receives. The distance from your wireless service provider’s nearest tower, the
construction of the building, the surrounding terrain, and the placement of the
SOMAport can potentially affect the strength of the signal.
The SAU
The SOMAport internal antenna provides good reception in most situations.
However, in rare cases, the internal antenna is unable to acquire a sufficiently
strong signal. The SOMAport supports an optional device, the SOMAport
Accessory Unit (SAU), to address these circumstances. The SAU is an external
antenna mounted on the outside of your home or building. Contact your wireless
service provider or retailer for more information about the SOMA Networks
SAU.
W A R N I N G :
While this device is in operation, a separation distance of
at least 20 centimeters (8 inches) must be maintained between the radiating
antenna and any person exposed to the transmitter in order to meet the
FCC RF exposure guidelines. No change to the antenna or device is
permitted. Doing so may result in the installed system exceeding RF
exposure requirements. This device must not be co-located or operating in
conjunction with any other antenna or radio transmitter. Installers and end
users must follow the installation instructions provided in this guide.
