  1. IDAS SolutionIndoor Distribution Antenna System

  2. Definition of IDAS • Indoor Distribution Antenna System • Distribute mobile communication signal inside buildings to provide coverage for the blind areas & shadow areas • Provide steady quality signals to collect the indoor mobile traffic.

  3. Why IDAS? In 2G network − About 70% of Voice traffic come from Indoor. − About 30% of Voice traffic come from outdoor. In 3G network. − About 65% of Data service come from Indoor. − About 35% of Data service come from outdoor.

  4. Different Applications Small • Small Building, • A lot of traffic • Quantity of antennas < 20 pcs

  5. Different Applications Medium • Apartment Buildings (Residential, Commercial) • A lot of traffic • Quantity of antennas is around 100 pcs

  6. Different Applications Large • Large buildings, Shopping malls, Airports • High traffic • Quantity of antennas > 150 pcs

  7. Wireless Repeater IDAS

  8. Wireless Repeater IDAS CAPEX* Capital Expenditure • Features Low traffic Sample system coverage • Consider Easy & short time Installation Low investment of CAPEX* Wireless Access • Application • Small Building, Villa…

  9. Wireless Repeater IDAS system

  10. BTS-IDAS system • BTS will be used instead of repeaters in the cases that repeater can not provide the sufficient traffic.

  11. Passive IDAS system

  12. Passive IDAS system • Features Medium traffic Sample system coverage • Application Medium buildings, basement • Consider Limited BTS output power BTS room required Capacity low efficient

  13. Passive IDAS system

  14. Disadvantages of Passive IDAS • BTS Output power is not enough. • A lot of RF loss is in feeder transmission. • Cost of RF feeder is so high. To solve these problems we can use Active IDAS system

  15. Active IDAS system

  16. Active IDAS system • Features high traffic Large system coverage • Application Large buildings, Urban Residential, Shopping malls Stadiums, Metro Stations, Airports

  17. Multiple Band Active IDAS GSM 900 GSM 1800

  18. Multiple Band Active IDAS • Components & Antenna Passive component and feeder suitable for 800~2500MHz • Combiner Dual or Multiple band access • Equipment • GSM900 MHz Optical Repeater • GSM1800 MHz Optical Repeater • 3G 2100 MHz Optical Repeater

  19. Thank you
