TM
is transparent to the network
because it enhances coverage without the use of additional frequencies,
alleviating complex frequency planning. By employing various patent pending
technologies, California Amplifier has integrated this functionality into a single,
self-contained device. Since Ecco requires no mounting hardware or difficult
installation for use, it is perfectly suited for consumer deployment in a residence,
SOHO or other in-building application.
Ecco is targeted for use by PCS carriers and may either be provided or sold to
PCS customers, the end user. Ecco provides an affordable solution to decrease
customer voluntary churn caused by spotty coverage and also increase revenue
potential by providing cost-effective and reliable in-building coverage.
Additionally, Ecco provides an opportunity to attack the landline replacement
market using wireless, by enhancing availability and reliability of the wireless link
in residences.
Product Operation
Ecco incorporates a high gain antenna that is intended to be directed toward
signal paths to / from the base station (called “Donor Antenna”), and a second
high gain antenna that is intended to be directed towards the interior of the
service location (called “Server Antenna”). Ecco contains electronics that amplify
signals between these antennas, in the specific channel block of interest. The
design and packaging of the two antennas in Ecco have been optimized to
maximize their isolation, thus accommodating a high gain electronic amplifier.
In order to aid the consumer in orienting the device to optimize signal paths to /
from the base station, Ecco has visual status indicators. These indicators inform
a user that the device is receiving sufficient PCS RF signal to provide
enhancement, and an indication of the strength of that signal. The display also
provides visual indication if a PCS RF signal does not exist or if the quality of the
signal received is too poor for Ecco to enhance coverage.
Ecco employs an adaptive gain control algorithm which continually and
automatically optimizes the gain based on a variety of conditions related to the
ever-changing surrounding RF environment. This adaptive approach simplifies
the product's placement and also eliminates any ongoing need for monitoring,
adjustment or reconfiguration by the customer.
Ecco has a “Power” button, which toggles the unit on and off. It also has a “Band
Select” button which allows the user to select the desired PCS frequency block,
alleviating complex frequency planning. By employing various patent pending
technologies, California Amplifier has integrated this functionality into a single,
self-contained device. Since Ecco requires no mounting hardware or difficult
installation for use, it is perfectly suited for consumer deployment in a residence,
