Distributed Antenna System (DAS)

The Distributed Antenna Systems (in-building wireless infrastructure solutions)

Distributed Antenna System (DAS) is the solution that provides mobile coverage inside township, where the coverage, capacity or quality would not have been otherwise satisfactory.

Cutting-edge Distributed Antenna System (DAS) design meets cabling innovation with operator-grade, enterprise-ready solutions.

The DAS portfolio of in-building wireless infrastructure solutions offers built-in RF intelligence and flexible architectures to fit every facility, large or small.

These innovative solutions enable a wide variety of technologies and advanced 4G LTE for the newest breed of mobile devices. The result is a solution that is widely recommended, adopted and installed in thousands of deployments worldwide.

Intelligent Design

The Total DAS portfolio enables design flexibility for high-rise, stadium, campus environments or single facility designs:

  • Leverages Common Headend Architecture : Built on a single DAS that supports all combinations of remotes, for scalable and cost-effective coverage and capacity.
  • Delivers Efficient Remote Power: Pre-configured, modular remotes simplify commissioning and minimize upgrade costs with standard, medium and high power, indoor and outdoor remote options.
  • Improves Performance with Advanced Cabling Solutions: Take advantage of intelligent cabling solutions and reduce installation time with Plug & PlayTM, composite and stubbed hardware options.
Hybrid DAS solution :

Our solution is a Hybrid DAS this is a combo of Active and passive DAS. This DAS system will support all the requirements of any types of customers. We are creating a central control room for all mobile operators and distributing the coverage and capacity from the central location to multiple locations.

We use the passive system for providing the coverage and capacity to the nearest area of the Central control room. We also apply the active system for providing the coverage for the far end area of the buildings. By using this hybrid solution, we can save the cost and extend the coverage and capacity to another location in the premises.

Digital Active DAS solution

A DAS consists of a master Unit or head-end linked to a mobile operator’s base station. The main hub transmits the mobile signal to remote units (RUs) and antennas, which amplify the signal in specific areas of the venue. Because of traffic demands, large venues are often divided into sectors, in which a specific frequency bands or operator’s service is distributed.

DAS solutions transport RF signals in digital format from the Master Unit to the RU. This means that the signal does not attenuate nor suffer any impairments or distortion between the master unit and RU, and the master unit can simulcast the digital signal to all of the RUs in the system. Digital systems can also be configured to support other frequency reuse factors, up to and including single frequency reuse. In other words, DAS systems can be configured to operate at any point on the deployment continuum emphasizing coverage to capacity. Digital transport offers peak RF performance and greater system architecture scale and flexibility compared to analogue solutions, and far less fibre infrastructure while offering Maximum bandwidth to capacity crowd.

Functional Features
  • Creates a common and non- discriminatory comprehensive coverage solution, which provides equal access for all wireless operators in CDMA, GSM900, GSM1800, WCDMA 2100 and LTE 2300.
  • Accommodates all current technologies and capacity requirements with the ability to add capacity and support emerging future technologies as need arises. In short , it’s a scalable system design
