What is an Outdoor Distributed Antenna System and how it works?

www.premier-cable.net


A Distributed Antenna System (DAS) consists of a network of antennas that facilitate wireless cellular connectivity of an area, structure, or building. DAS technology addresses service gaps caused by conditions such as mobile data growth and large areas of heavy traffic. The deployment configuration of DAS is highly customized according to the environment. Depending on the situation, Ethernet, fiber optic or coaxial cables connect the antennas to the base station. Through one of the transmission media, the antenna broadcasts signals from participating operators. Base stations are also custom built to boost the signal and distribute it through various parts of the site. DAS is transformative in areas previously with little or no cellular coverage.

 

 

The Outdoor Distributed Antenna System (oDAS) amplifies and transmits carrier signals in complex, spacious outdoor environments. Open-air environments pose serious challenges to wireless connectivity. Using multiple antennas outdoors can increase capacity and quality while reducing cumulative power consumption.

 

 

How Outdoor DAS Works?

 

The vast, complex geographic areas served by oDAS require long-range antennas and amplifiers to reach places that cell towers cannot. Optical fibers are used to transmit signals to and from remote nodes. Optical fibers are connected to the basic unit that generates, converts, refines and controls signals. Remote Radio Heads (RRH) are sometimes used to send and receive signals. RRH nodes are protected by waterproofing measures in public areas exposed to the elements. Many oDAS systems are active configurations. Active DAS can be used when the logistics dictate that the signal needs to be transmitted directly from the fiber to the RRH. Active DAS requires a dedicated power supply and is easily scalable because it does not use coaxial cables. Active DAS networks are ideal for densely populated outdoor spaces where superior performance is required.

 

 

Cabling and connectors are essential components of a DAS, as they physically connect the various components of the system, including antennas, DAS equipment, and signal sources. The type of cabling and connectors used in a DAS can significantly impact the system's performance, as well as its installation and maintenance costs.
