Cellular Coverage System

HETERO-DAS

HDAS model : HETERO-DAS

Overview
The system is designed to minimize the dual infrastructure investment in case of deploying new services and enable the simultaneous services of 2G and 3G by utilizing the 2G infrastructure installed  in the main building  with in-building integrated RF distributed antenna system (DAS) and aims to relieve the regional gap of service range by accommodating the 4 Sector, dispersing traffic and expanding the coverage. It accommodates 3FA and all the WCDMA operators within  the bandwidth can use it. It is the system that is implemented to service the future LTE by adding additional RU equipment.
Major Functions
- The system that enables new services with minimum investment (shares the existing infrastructure)
- The system that enables the deployment of the future LTE services (2 Sector, MIMO)
- The system that disperses traffic and increases the service quality (4 Sector)
- The system that accommodates the Legacy (2G) service (CDMA/GSM)
- The system that facilitates the location selection within the building (external power outlet not required)
- The system that is compatible among operators (minimizing the component replacement)
- The operation and management of the system with local GUI
- The remote management and control through NMS server
Key Features
- Integrated 2G.3G & LTE service
- Expansion of LTE RU (1) through RU
- The OPEX/CAPEX cost reduction of the operation using the existing infrastructure
- The dispersion of the maximum number of 32 RU
- East to expand and upgrade the service as the modular structure
- Accommodates the maximum 40 watt/sector signal that is emitted as BTS
- Power supply via coaxial cable
- The miniature (A4 size) is easy to install on the roof of the interlayer
