TETRA Base Stations

Nielson Networks is proud to feature PowerTrunk equipment as as an excellent communications solution. PowerTrunk, based out of New Jersey, is a division of the Spanish company Teltronic. PowerTrunk is well known for their excellent engineering designs, reliable equipment installation, and rock solid technical support. Teltronic has TETRA installations all over the world, and continues to innovate their TETRA products. By innovatively developing 100% of the TETRA product, they are able to deliver exact solutions satisfying customer specifications.


PowerTrunk TETRA systems consist of 3 fully redundant components: System Control Node(s), Site Base Station(s), and ethernet IP connetivity. PowerTrunk equipment is available in 450 - 470 MHz, and 806-870 MHz, the standard bands for TETRA in the US.



  PowerTrunk SCN

System Control Nodes (SCN)

Each PowerTrunk TETRA system requires at least one System Control Node (SCN) which manages the radio system. This management includes the registration of terminals onto the network, network monitoring utilities validating system health, and interactions with the outside world, such as VoIP telephone calls allowing radio terminals to call out to normal telephones.


System Control Nodes may be installed with a redundant component which will take over in a moment's notice. Using IP connectivity, these redundant components may be located in different areas, allowing for geographical fault tolerance. If distances are too great for ethernet connectivity, fiber cables may be easily implemented to make the connections.


SCN computers operate using the world-class VxWorks operating system -- the same OS that NASA trusted with Mars probes, Boeing with the Dreamliner 787, and other mission-critical operations.


  PowerTrunk SBS

Site Base Stations (SBS)

Site Base Stations (SBS) feature the TETRA transmitters and receivers for radio communications. Often located at the base of a radio tower, these units provide up to 75W of transmission power, and triple diversity reception capabilities. Mounted inside standard 19" communications racks, several transmitters, receivers, and filtering may be all neatly arranged within a single enclosed rack. Expansion is not a problem, as the systems are all IP based: install the new transmitter, wire the antenna, click in the network cable, program it up, and get the new unit onto the air.


PowerTrunk offers multi-slot packet data, up to 28.8 kbps, voice and data communications, Air-Interface & end-to-end encryption options, and other redundancy options. If network communication fails, an SBS can be configured to operate in stand-alone mode, allowing radios attached to the single SBS to interact with each other.


  PowerTrunk MBS

Mast Base Stations (MBS)

Mast Base Stations (MBS) are designed to be mounted on a tower, or anywhere else, requiring a small single-carrier installation. The MBS is a complete base station, designed to either stand alone as a single unit (such as a High School, small office or warehouse, or a small worksite), or as part of a larger TETRA network, enhancing coverage in weak areas, or for quick expansion of a network. The MBS may be combined with a second MBS, allowing for 2 operating carriers, or in a backup standby mode for fault tolerance.


The MBS transmits at 10W, and is capable of diversity reception. The unit contains an internal duplexer and multicoupler, so the radio system is completely self-contained. MBS is certified to operate from -30C to +60C, and is IP66 resistant. External ethernet jacks support either line-supplied networking from the ground, or they may be connected to wireless microwave networking. The MBS may bridge the network, relaying data from one access point to another.


The MBS is fully weather resistant, and may be mounted in the snows of northern Minnesota, or the tropics of Florida.

  PowerTrunk PBS

Portable Base Stations (PBS)

Portable Base Stations (PBS) is a trolly-mounted "MBS on wheels" designed to be rolled to a location, and connected to some antenns, and provide a small single-carrier installation. The PBS is a complete base station, designed to either stand alone as a single unit, or as part of a larger TETRA network, enhancing coverage in weak areas, or for quick expansion of a network.

  PowerTrunk DBS

Deployable Base Stations (DBS)

Deployable Base Stations (DBS) is a TETRA base station mounted in a smaller rack, and designed to be deployed in areas too large for a PBS. Capable of up to 4 carriers, this weather-hardened communications machine also may operate in a stand alone mode, or connected to a larger TETRA network. Simply roll the pre-configured station to the jobsite, attach the antennas and electricity, and turn it on.
