IBS OVERVIEW

IBS means Wireless In-Building Solutions

 

  • Bringing the cellular service inside the building to provide better quality

  • Provided by Distributed Antenna Systems (DAS) to evenly distribute signals in every corner

WHY IBS

Increased mobile traffic and usage, driven by: 

 

  •  More capable devices

  •  Increasing usage indoors

  •  Demand for higher data rates and quality

  •  Reduced traffic prices/flat rates

  •  Increased acceptance for mobility

  •  Fixed phone replacements

 

 The in-building challenge: RF performance

 

  •  Users receive weak signals from many base stations or no signal at all due to isolation.  

  • Metallic coated windows, thick concrete walls, steel etc attenuating the signal. 

  • The solution is to have a dominant signal.

 

The in-building Challenge: Capacity 

 

  • Mobile service is crucial inside buildings as  majority of the calls are made inside.

  •  Dedicated capacity is needed inside big buildings, venues etc to improve quality and overcome the outdoor traffic congestion.

  •  No impact from outdoor traffic.

WHERE DO WE NEED IBS

 

  •  Offices/Industries

  •  Airports, bus/train stations

  •  Tunnels

  •  Conference and exhibition centers

  •  Hospitals

  •  Hotels

  •  Shopping Malls

  •  Stadiums

  •  High rise buildings

 

DAS

 

  • DAS- Distributed Antenna System  

  • Distributed Antenna System (DAS) solutions provide coverage in areas where there is either no coverage or the macro environment is only partially covering.

  • DAS is the concept of distributing an RF signal by splitting over several antennas.

  • A DAS can be implemented passively using splitters and feeders, or actively using repeaters, radio remotes with transmission over fiber.

  • Passive DAS- Coax used to distribute RF signals

  • Active DAS ‐Adds RF over FO conversion, fiber, and distributed amplifier
