What we supply
- Bi-directional amplifiers for TETRA 380–400 MHz. Other bands and regions on request: VHF 136–174 MHz, UHF up to 512 MHz, 700 MHz PPDR broadband; DMR and P25 on VHF and UHF
- Digital band-selective filtering with adjustable bandwidth; power class and filter bandwidth per build specification
- Fibre-fed remote units for long tunnels and large buildings
- Per-band level and VSWR monitoring, with local and remote management
On the ASTRID network, only repeaters and base stations validated by ASTRID can be used. Our catalogue models are not on the list ASTRID has published (January 2024 version), so we check the current list with you first. Read how this works for tunnels.
What to send
- The network and band, for example TETRA 380–385 / 390–395 MHz (uplink / downlink)
- The channels or the bandwidth to carry
- How the signal is fed: a pick-up antenna towards an outdoor base station, or an indoor base station
- The building or tunnel: floors, area or length, and floor plans
- The available power supply, any backup-power requirement, and how alarms must be reported
Digital core and management designed in Brussels
The next step for this line is a channel-selective digital repeater whose signal processing, management software and interfaces are ours: TETRA and LTE in one unit, remotely configurable band plans, a management server hosted within the EU or on the customer's own server, and an open interface into the integrator's monitoring. The digital core is planned on the same FPGA and host software as our SDR platform.
The amplifiers and remote units listed above are supplied today; this digital core is a later addition. In development; no pilot units yet. Integrators with a concrete project can send us their requirements now.
