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,
- 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.
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.
