UNDERGROUND
METStech in-line BDA for Hard Rock mines and Tunnels
ABOVE GROUND
Dual Band BDA's for above ground use in remote areas.
BDA SPECIALISTS
We design and manufacture leading-edge Bi-directional amplifiers for the propagation of virtually all communications technologies.
In 2016 we delivered the first in our series of low latency, highly linear BDA for two way radio technologies including TETRA for the underground hard rock market.
In 2017 we released new products to support LTE over leaky feeder cable to underground mines and tunnels. The product includes a two-way radio BDA so the same product can replace existing underground BDA systems to provide LTE and Two Way communications on the same leaky cable.
Propagating communication signals underground
METStech BDA solution amplifies and propagates radio communication signals using the leaky-feader principle. BDA's can be linked together via a radiating cable to provide coverage laterally along the length of roadways and tunnels where conventional antenna systems are sub-optimal.
Our design has an incredibly small latency removing the need for expensive fiber fed picocells.
METStech systems work with multiple vendors hardware such as LTE cores and two way repeaters.
SIMPLE TO DESIGN
The LTE BDA system works similar to an existing underground two-way radio system. The design rules are based on length of run and splitters inserted in the path.
DUAL PURPOSE
Our BDA is available for VHF, UHF, VHF + LTE , or UHF + LTE. This allows the same cable to support your existing two- way and LTE communications.
SIMPLE TO INSTALL
The radiating cable is terminated with a N type connector and the BDA inserted every 150- 300m dependent on frequency. Electricians experienced with existing two-way BDA systems will be able to install an advanced LTE solution.
