DAS

Choctaw Defense Services designs cost-efficient coverage and capacity solutions that provide functional solutions for mobile phone users in the in-building environment. Our team provides on-site assessments, system designs, and cradle-to-grave deployments of these solutions. We stay up to date with all major wireless service providers and leading equipment manufacturers.

Choctaw Defense Services sees an increasing usage in cellular communications, often resulting in poor reception in office buildings, parking garages, and airports. Users need reliable wireless coverage to work efficiently and effectively, but low quality signals, dropped connections, and lack of coverage decrease productivity,

A Distributed Antenna System, or DAS, is a network of spatially-separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure. DAS antenna elevations are generally at or below the clutter level and node installations are compact.

The idea behind DAS is to split the transmitted power among several antenna elements, separated in space so as to provide coverage over the same area as a single antenna but with reduced total power and improved reliability. In other words, a group of low-power antennas that cover the same area replace a single antenna radiating at high power. These types of antennas have recently been employed around the United States by several service providers.

Challenges –

DAS is used in scenarios where alternate technologies are not feasible due to factors such as terrain, zoning challenges for cell towers, unfeasible cell tower placements, etc. However, several regulatory challenges at the federal, state and municipal levels arise out of DAS deployments. Recent academic works and industry resources such as The DAS Forum address these regulatory issues.
