Bird Das Bird RF

You hold a responsibility in the operation of a building or construction such as a large office building, hotel or stadium. And you get reports that the indoor coverage of wireless networks such as GSM, LTE and those networks used for public safety (C2000) is poor. You need to improve this indoor coverage but cannot make the network operators to put in additional capacity. And you want to be flexible towards the future for new networks that may arrive.

    Go passive or get active

  • There are basically two options to improve the indoor coverage of wireless networks; by the use of a passive system and by the use of an active system. A passive system makes use of antenna’s to receive the wireless signals and then passively relay these signals to indoor antenna’s. This improves the indoor reception typically with several db’s. An active system receives the wireless signals and then amplifies and distributes the wireless signals to indoor antenna’s. Heynen offers passive systems as well but in this article we focus on the active system – Distributed Antenna System (DAS) – from Bird (DeltaNode).

    • Increase in-building coverage

  • The RF experts from Bird offer a mature and flexible DAS that allows stable indoor coverage and communication over wireless networks. It supports the frequency bands that you need including GSM, 3G, LTE and C2000. You can carry up to four bands in one DAS chassis. The system can be completely configured by remote over an IP connection. A typical installation consists of base station interface cards, a fiberoptic network to connect the central unit to remote units and repeaters that will transmit the RF signal. Obviously the output power of the transmitter is relatively low because you don’t want interfere with network operators networks or apply for licenses to transmit an RF signal.

    • Specify your DAS

  • Specifying a DAS that answers to your specific situation can be challenging task. There are many things that you need to take into account. These include the layout of the building, physical information related to the building and the details of the wireless networks which indoor coverage you need to improve. You can find some best practices in the whitepaper below.

    • Main Advantages

    Flexible DAS with different system components to choose from
  • Multiple frequencies in one system
  • Fully configurable over IP

  • Bird pocket-sized SiteHawk Antenna and Cable Analyzer

    Bird has released a new version of their widely used antenna and cable tester the SK-4500.

    The FDR (Frequency Domain Reflectometry) measurement method results in a highly reliable assessment of the health of critical components in your system; ultimately providing a “heads-up” before a failure occurs.

    The device is an excellent help to do the end verification of a system upon delivery by generating a completet measurement wihich later during the service of the system can be used as a reference.

    Fault location or DTF mode indicates VSWR or Return Loss levels at each point along the cable and antenna system length. This helps in debugging a failing system

    Cable Loss function measures insertion loss of the cable system over a given frequency range.

    An excellent help to your engineers in delivery, maintenance and repair. A low cost solution with excelllent performace in and outdoor.
