This application is a cost-effective means of connecting multiple remote locations back to a central location to alleviate the need for expensive T1 or Fiber installations.

As defined by PCIA, The Wireless Infastructure Association:

A Distributed Antenna Solution, or DAS, is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure. DAS antenna elevations are generally at or below the clutter level and installations are compact.

A distributed antenna system can be implemented using passive splitters and feeders, or active repeater amplifiers can be included to overcome the feeder losses. In systems where equalization is applied, it may be desirable to introduce delays between the antenna elements. This artificially increases delay spread in areas of overlapped coverage, permitting quality improvements via time diversity.  DAS are customized for individual installations and designed to suit each facility.

A cellular network is a radio network made up of a number of radio cells (or just cells) each served by at least one fixed-location transceiver known as a cell site or base station. These cells cover different land areas to provide radio coverage over a wider area than the area of one cell, so that a variable number of portable transceivers can be used in any one cell and moved through more than one cell during transmission.

Cellular networks offer a number of advantages over alternative solutions:

1. Increased capacity

2. Reduced power usage

3. Larger coverage area

4. Reduced interference from other signals

BDA’s are similar to the cellular broadcast towers used to broadcast by the network providers, but are much smaller, usually intended for use by one building. Modern cellular repeater amplifiers work by rebroadcasting cellular signals inside the building. The systems usually use an external, directional antenna to collect the best cellular signal, which is then transmitted to an amplifier unit which amplifies the signal, and retransmits it locally, providing significantly improved signal strength. The more advanced models often also allow multiple cell phones to use the same repeater at the same time, so are suitable for commercial as well as home use.

Harris Communications implements a multi- carrier repeater solution for the physicians lounge at Cleveland Regional Medical Center

Shelby, NC (February 23, 2009) Cleveland Regional Medical Center was seeking in-building cellular signal enhancement for the physicians lounge to facilitate cellular signals in a confined area. As an answer, Harris Communications custom designed and implemented the Distributive Antenna Solution (DAS) for all carriers to ensure adequate in-building cellular phone signal for the physicians lounge and surrounding area.

Harris Communications designs and implements a multi- carrier cellular signal repeater solution for Jupiter Medical.

Jupiter, FL (December 9, 2008) Jupiter Medical facility was seeking in-building cellular signal enhancement to maximize operational efficiency and improve patient care. Harris Communications was able to custom design and implement a turnkey Distributive Antenna Solution (DAS) for all carriers to ensure adequate in-building cellular phone signal. As hospitals move towards total mobility, more facility managers are seeking facility-wide wireless coverage to support critical functions.
