The Distributed Antenna System (DAS) is the technology that is used to boost network coverage in areas where there is either no coverage or areas with weak coverage. In order to achieve this, the technology relies on a clustered installation of antennas for boosting the cellular network. The system is common in large facilities, underground transport systems, and in the areas with large gathering that leads to a high demand that overwhelms the available network coverage. As such, you are likely to find the cellular DAS in airports, sport arenas, large hospitals, and town city centers like Raleigh city among others.
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.
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.
In any DAS project, the deployment stage is the most expensive. This is mainly due to the labor intensive process of antenna installation and stinging the coaxial cable or the fiber optic in between the antenna modules and the controller.
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.
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.
