DAS-HUB System Design
In Building and hot-spot Coverage
OGC can assist operators to design and implement Picocellular-DAS-HUB networks, for both RF coverage or capacity challenges.
Cover and capacity expansion with a DAS system can be done in the following cases:
- Subways and stadiums
- Tall buildings and on campuses such as universities, enterprises and hospitals
- In residences and neighborhoods (shaded areas)
- On cruise ships and along coastal areas.
Services may include consultancy or full turnkey solutions.
OGC utilizes the best modeling tools in the wireless industry for:
- propagation modeling,
- RF data collection,
- and optimization.
From iBwave with the optimization tool bridges to fulfill the gap between outdoor and indoor wireless networks by extrapolating outdoor wireless signals inside the building to assess:
- signal quality,
- interference,
- and data rate.
DAS-HUB System Installed
OGC was a pioneer company in foreseen the need for in-building coverage from the early days of the wireless industry. Toward that goal, In 2002 OGC signed an agreement with ADC in the NY region for providing engineering and equipment support for in-building and outdoor (in shaded areas) wireless coverage and capacity in places where service providers had difficulty of delivering their services properly.
The projects that Odyssia got involved are the following:
- Turn key solution for the DAS – HUB system installed in IBM’s Research center in White plains, NY for Sprint PCS.
- In all Sprint’s stores located in the NY metropolitan area Odyssia installed a picocell.
A typical DAS System for Coverage/Capacity expansion.
Pair of Fibers for digital uplink and downlink
RF Coaxial Cable
System configuration consists of the following units:
- DHU - Digital Host Unit.
- DRU- Digital Remote Unit.
- DEU- Digital Expansion Unit. It enables 6-way expansion.
- In the upling the DRU digitizes the RF signals and converts them to digital optical signals for transport to the DHU and vise versa for the downlink.

Fiber Optic Network Services
OGC been in Communication Business with a deep understanding of the growing demand for broadband telecommunication links got involved in the fiber optic (FO) industry in 1999 through the fiber optic backbone of a control and communication project for New Jersey Transit.
Since then, Odyssia offers a comprehensive service for all aspects of fiber-optic installation from project management, through civil works to splicing and testing.
OGC’s FO network capabilities:
- Metropolitan Area Networks
- Last mile connection
- Fiber to the home
The activities of OGC in the FO industry are:
- Fiber optic cable installation
- Fiber optic splicing
- Fiber optic testing
- Fiber optic repairs
OGC has done wok in the fiber optic industry for Metromedia Fiber Nertworks, Verizon, FiberNet, and Bechtel.
Special Projects – FO combined with wireless
- Fiber optic for LTE projects
- Fiber optic for DAS-HUB projects
Control And Communications For Railroads
In the rail road industry Odyssia designed a telecommunication and control system of the Hudson–Bergen Light Rail for New Jersey Transit. A two million project.
For the Hudson–Bergen Light Rail (HBLR), OGC designed a sophisticated communications and control system utilizing an asynchronous fiber-optic backbone and T1 Multiplexers to collect voice, data and video signals from various subsystems throughout, the rails, the train stations and the trains.
The subsystems designed in the communications and control system of the HBLR are the following:
- Control system for finding the location and direction of the movement of the train
- Emergency call for aid - voice and CCTV systems
- Public address information system
- Wireless voice and data communication system with a train in motion
- Rail traffic control central equipment monitoring
The subsystems designed in the communications and control system of the HBLR are - continue:
- Ticket vending machine network
- Fire and intrusion alarm system
- Turn ON/OF the elevators of the train stations from the Operations and Control Center room (OCSR)
- 24 hours voice video and data recording.
In the next figure, one can see a typical design (installed by others) at a train station of the HBLR.
- T1-Multiplexers (2 for redundancy)
- Fiber optic modems T1 to Optical (2 for redundancy)
- ISDN Modem For Video transmission
- Power amplifier for the public announcements system
- Telephone for intercommunication
- Data modem collecting control signals from various location
The collected information from all subsystems of the sixteen train stations, mentioned above, are traveling through:
- the fiber optic back bone to
- Fiber optic modems Optical to T1 (2 for redundancy) to
- T1 Demultiplexers (2 for redundancy) to
- the Operations and Control Center room (OCSR)
- from where the HBLR’s preventing maintenance team can monitor and control all remote subsystems i.e. turn ON/OFF an elevator at a train station
For all mentioned systems, subsystems and equipment designed in this in the Light Rail project, OGC performed quality assurance tests complying with the ISO 9000 industrial standards.
