Distributed Antenna Systems: Better Connection, Better Communication
July 17, 2014 Technology
communication technologyOver the last half a decade, the use of wireless communication systems has seen a significant increase. This only shows that people are now communicating not just through the Internet from their homes and offices. They’re also connecting with anybody from anywhere even while on the go using their mobiles.
A shift in the usage pattern of the World Wide Web requires a parallel shift in the communication technologies to keep customers happy. This technology has been introduced as the Distributed Antenna System (DAS).
What is DAS?
As an advanced technology service, DAS is a way of dealing with areas of poor coverage within a large building. Several small antennas are installed throughout the building that serves as repeaters. These antennas are connected to a controller, which is networked to the base station of a wireless carrier.
In an indoor space that get densely populated, such as shopping centers and skyscrapers , this kind of a small-antenna service makes sure that every area of the building will get network. So, it does not matter which corner of the building people go to. There is always available and accessible data and voice services.
Passive and active DAS
DAS can be either active or passive.
In passive DAS, the smartphone signals are received by the antennas, which run them through leaky feeder cables throughout the building. In this method, it is the leakage that helps distribute the signals.
In active DAS, the signal is not leaked. Instead, it is passed from the antenna via fiber cables. The advantage here is that the signal can be amplified or boosted if needed.
Benefits of DAS
According to onepathsystems.com, DAS provides extensive coverage over huge premises and does not require any special towers, as the antennas can be attached to light poles and rooftops. Also, it uses multi-band remotes that reduces the fiber cable requirement. In addition, it is more cost effective, as the network planning and design is simple. If amplifiers are placed outdoors, there is less need for cooling.
Finally, the DAS ensures happy customers even in crowded places. Could a customer or the wireless carrier want anything more?
