Dual Band Cellular Repeater

Posted by Perception System Thursday, June 9, 2011 0 comments

Cellular Repeater
Developing Various Products for the Telecom Industry.
Shireen Inc. develops various products for the Telecom Industry; understanding that there still remain a vast majority of regions, industries and people who do not receive a sufficiently strong cell phone signal. This State of the Art Dual Band Repeater/Amplifier design increases signal strength and improves cellular communication without a physical connection to the cell phone.

The amplifier has a typical signal gain of 50dB which is automatically controlled using proprietary digital design. It can be employed in large yachts, homes and offices.

The Dual Band Cellular Repeater/Amplifier works in the following manner: An outside antenna (placed outside the premises) receives the signal from the base station, the Cell Amplifier unit amplifies the signal and repeats it to the cell phones through the inside antenna (placed indoors). You get the freedom to walk around while talking on your phone. This technology allows clean and clear wireless functioning of multiple cell phones operating in the 800MHz or 1900MHz bands.
