In order to deal with the isolated spots that have poor network coverage inside a large building, a network of small antennas are usually installed in the building to serve as repeaters. This is known as the distributed antenna system (cellular DAS). The technology is very important in the areas that have a weak coverage or no coverage, such as the underground transportation system, and college campuses. It also offers a suitable solution in places with large gathering where the existing network coverage is overwhelmed by the demand such as in the sport gatherings, airports, and hospitals among others that are common in the Raleigh city.
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.
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.
The DAS systems offers the voice services and data services to all mobile devices in densely populated areas like the shopping malls, tall buildings, sport arenas, and the university or college campuses. Generally, the technology eases the zoning and antenna placement, less power consumption, and reduces the need for site development. In addition to this, less BTS are used since the Simulcast means less need for the Backhaul.
