Advantages of ClearFill Star system versus a typical distributed antenna system:
Lower costs for hardware and installation:
Installation costs are reduced by the use of existing infrastructure.
All remote radio heads / active antennas (RRH) are powered via CAT5 cables and
the Power of Ethernet (PoE) functionality that eases the installation considerably.
CAT5 cable (+fiber) versus coaxial cable (+fiber).
Gig-E components versus RF components.
Solution is future proof, because the used transport medium will evolve with Ethernet
evolution; 10 GBit Ethernet solutions are already entering the market.
Costs are competitive due to huge Ethernet market: the benefit is a massive economy
of scale.
Higher flexibility:
Ability to adjust output power per RRH via software.
Supports diversity and sectorization for increasing capacity without additional
hardware.
OA&M functions are integrated in same Gig-E network.
Conversion between fiber medium and CAT5 medium is done easily.
System is flexible and scalable.
Higher performance:
Highest quality of service; due to digitization of the RF signal directly at the source no
degradation of the signal due to distribution.
Digital transport does not degrade RF signal quality.
Elimination of gain uncertainty in the system.
Capacity and coverage are independent with ClearFill®Star:
1 sector worth of capacity can be distributed to multiple RRHs covering a large area
or a single RRH covering a small area resulting in a very flexible growth.
Capability to manage base station capacity. The software assigns Remote Radio
Heads (active antennas) to base station or base station sectors.
Softer and soft handoff features are preserved.
Welcome to the next generation of active Distributed Antenna Systems, welcome to
ClearFill®Star!
