There are many situations where some spots have poor cellular network coverage. In some cases, the network is not available at all. This is common in high rise buildings, underground transportation systems and the highly populated areas like shopping malls, hospitals, college campuses, and stop arenas where the existing network system is overwhelmed by the demand such as many places in Raleigh city. The distributed antenna system, also known as the cellular DAS is the technology that boosts network coverage in areas with poor connectivity by installing a network of small antennas in the area that serve as repeaters.
In order to increase the signal reliability while reducing the total power required doing so, the DAS installation is made of a network consisting of several antenna nodes that are separately installed. The nodes are then connected to a single common source using fiber or a coaxial cable. This means that power is transmitted among several antenna elements which in turn reduces the power consumption and increases the network signal reliability.
The additional antennas mean better network coverage. The additional antennas are able to increase the line-of-sight channel that is responsible for a better network coverage. In normal systems, the provision of the cellular signals can be very power consuming since the system has to overcome the shadowing effect and penetration problems all which lead to the loss of signal.
In this way, the network is distributed through signal leakage. Since the transmitted power is split among a number of antenna elements that covers the same area as a single antenna, the total power required is highly reduced.
The DAS antenna nodes can be installed indoors as well as outdoors since they are very compact. They are also small in size and the power requirement is less. This means that the system can be installed at any remote location where the zoning restriction cannot allow the traditional cell towers to be installed. In some cases, the system is tied to the wireless carriers like the AT&T and the Verizon. In most cases, the neutral-host providers are used given that they come with multiple carrier ability.
In the carrier-owned DAS, it is the job of the wireless service provider to pay for the equipment cost, the installation cost, and the cost of maintenance and upgrade. The DAS installer on the other hands has the exclusivity on it, and the competitors can only use it at a fee. However, it may also be installed by a third party that is neutral to all the players. In this case, the entity bears the costs and recoups it by charging the service providers that have the system access.
However, in the case of a carrier-owned DAS, the wireless service provider is the one to pay for the cost of equipment, the equipment installation cost, and the maintenance and upgrade of the same. The installer, in this case, has the exclusive rights on the system. As such, the competitors have to pay the installer to use it. In some cases, the installation is done by a third party entity that bears all the costs and recoups the cost by charging the service providers in order to get the system access.
With the DAS system, it is easy to offer the voice and data services through the mobile devices to the users in the densely populated areas where the typical system is overwhelmed by the demand. The system is also suitable for the remote locations that have poor network coverage or those with no coverage at all. Today, it is widely used in the city of Raleigh. It comes with the advantages of easing the zoning and antenna placement, no need for site development, and consumes lower power.
