Hytera Bi-Directional Amplifiers (BDAs)

Cost-effective and flexible radio communication solutions for coverage in challenging environments.

A BDA (Bi–Directional Amplifier) is an RF signal booster used to improve radio communications in situations where radio signal levels are degraded due to obstacles in the radio path. This might be in tunnels, high rise buildings and underground car parks where their construction can prevent the signals from a source reaching the users in these areas.

They are available in a number of variants to suit the communications situation, which includes integrated and distributed configurations and band and channel select options.

Sports stadiums
Stadiums can be complicated due to their semi-open design and reinforced concrete structures. Many stadiums have key areas spread around the site which need to be connected including entrance gates, spectator and player areas, offices, security areas, VIP rooms, equipment rooms, medical areas and more.

Hotels
With multiple floors and complicated building structures with many partition walls, total indoor coverage within hotels can be difficult to achieve. Offices, lobbys, corridors, elevators, meeting rooms, dining rooms, equipment stores and underground parking all need to be connected for the best guest experience.

Transport hubs
Train stations, airports and other transport hubs are often semi-open, reinforced concrete structures with few partition walls and high ceilings. Connecting all key areas of the hub including halls, lobbies, security areas, waiting areas, shopping and eating areas and parking can be challenging.

Tunnels and underground
Perhaps the most complicated settings for communication, these areas are often fully enclosed locations surrounded by thick layers of concrete and spread over long distances. Tunnel and underground communication becomes even more complex when, as is often required, coverage needs to include not only the tunnel and platforms but also outside and above ground areas.

Shopping centres
Achieving total coverage in shopping centres is vital considering how many people are moving through the structure at any given time. However, this is a challenge considering they are often complicated buildings with thick concrete supporting structures, multiple floors and several communicaiton black spots.

The Hytera BDA range

BDAs are cost-effective and flexible ways to overcome coverage challenges in difficult locations such as high-rise buildings, basements and tunnels. They can extend coverage and integrate seamlessly with many different radio systems.

DS-9300 series

  • Multi–network type: DMR, PDT and TETRA are supported.
  • Easy to deploy: DS–9300 is small and lightweight with flexible mounting options.
  • UHF: DS–9300 supports 400–470MHz.
  • Excellent out-of-band rejection. The DS–9300 starts signal rejection from 50KHz, which provides excellent rejection of out-of-band signals, which enhances coverage and voice quality.
  • Excellent intermodulation attenuation: for the DS–9300, 8 carriers deliver –45dBc. Intermodulation attenuation which is effective in eliminating the interference of intermodulation signals. This helps to provide better coverage and voice quality.

TS-9200 series

  • Multi-network type: DMR, PDT, TETRA are supported.
  • Integrated and distributed: TS–9200 offers both options.
  • VHF: TS–9200 supports VHF (136–174MHz) and UHF (Integrated model only) (350–520MHz).
  • Channel and band select variants: TS–9200 supports both options.
  • Analogue fibre: some TS–9200 BDAs can be connected with analogue fibre.
