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.
Basically, the DAS system is able to increase the signal reliability with far much less power consumption. This is achieved by installing a network of separate antenna nodes. All the nodes are then connected to a common source via a coaxial cable or a fiber cable. In this way, the power gets transmitted to several antenna elements which results to the reduced power consumption with increased network signal.
The system works by simply relying on the presses of additional antennas which in turn increases the chance of a good line-of-sight channel. Since the provision of cellular signals is a very power demanding process due to the problems penetration and shadowing that leads to signal losses, the DAS relies on the active repeater amplifiers or passive splitters and feeder configurations. The two configurations increases efficiency and thus reduce the power consumption.
The DAS on the other hands relies on the active-repeater amplifiers and the passive splitters as the means of feeder configurations. As a result, the efficiency is highly increased while the power consumption is reduced.
Since the installation is quite expensive, the industry is an option for the long contract terms. The most common of these is the ten year contract that is quickly becoming the industry standard.
In most cases, the cost of the equipment, installation cost, maintenance cost, and upgrading of the system are all borne by the carrier. This means that a carrier is likely to accept to bear the cost if the deployment fits within its network plan and is able to cover a large number of the subscribers. In most cases, the DAS system is shared with multiple carriers to keep the cost down.
The distributed antenna systems are transparent to the mobile devices. It provides the voice services as well as data services to the mobile devices. It offers the most appropriate solution to the densely populated spaces such as the university campuses, shopping malls, sport arenas, the medical centers and the tall buildings.
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.
