Building the Infrastructure

Evaluation of Existing Infrastructure

l

Existing Analog and LMR systems had TX / RX sites at various locations at the plant. Each TX/RX channel had different performance based on antenna location.

l

Existing North Cellular Tower (NCT) located in an ideal location, but needed a new shelter to house the equipment.

l

Construction of a new tower at the South Warehouse Building (SWB) to cover southern half of the plant, and provide failover options. Radio equipment installed inside a secured room within the SWB.

l

RX Diversity antennas added at each location to enhance RX performance.

l

IP Networking installed at each location, connected with fiber cable, allowing communications among the towers, and the Dispatch System (CeCoCo) unit.

Antenna Systems

l

Installed 6 RFI Model FSA20-67 (5 dBd) and 4 FSA10-67 (7 dBd) antennas.

l

Offset (cardioid) pattern with 130 degree Horizontal Beamwidth.

l

High front to back ratio, allowing frequency re-use, or aiming the antenna for greater gain.

l

Base Stations

l

Site Base Stations (SBS) arrived from PowerTrunk 90% configured.

l

PowerTrunk built, tested, and certified at the factory, along with the System Control Node (SCN) and Dispatch (CeCoCo) components.

l

NCT and SAB have 6 transmitters each, with one serving as redundant hot-standby.

l

Current configuration of 5 frequencies at each site allows for 19 talk paths at each site.

l

75 Watts delivered to the combiners; 32 Watts delivered to the antenna connector at the top of the cabinet.

l

System Controllers

l

System Node Controllers (SCN) arrived from PowerTrunk 90% configured.

l

PowerTrunk built, tested, and certified at the factory along with the Base Stations (SBS) and Dispatch (CeCoCo).

l

Installed one SCN at each tower site, providing redundant performance.

l

SCN systems manage the registration of terminals, along with gateways to external devices, such as databases, IP network relays, and telephone connectivity.

l

Network Management System (NMS) Client manages components within the SCN.

CeCoCo Enhancement

l

Centralized Command and Control (CeCoCo) unit installed at the South Admin Building (SAB), and connected to SCN’s over fiber network.

l

CeCoCo provides a variety of TETRA system enhancements, such as GPS integration, Dispatching solutions, and exporting of system audio from TETRA into other formats.

l

FHR uses CeCoCo to connect with analog users who have not migrated to TETRA yet.

TETRA RF Gateways

l

Using CeCoCo, TETRA audio conversations may be linked to Analog / LTR systems.

l

RF Gateways allow for a gradual transition from legacy systems onto TETRA systems.

l

Conversations are linked bi-directionally between a TETRA talkgroup, and an external talkgroup, such as LTR, Analog, even P25 or DMR.

l

FHR uses an RF Gateway to link TETRA to some LTR repeaters. This supports units who have not migrated to TETRA yet.

TETRA Data Gateways

l

TETRA supports full-duplex audio traffic, allowing radio users to have a telephone conversation over the radio.

l

Using SIP connections, telephone calls may be routed into and out of the TETRA radio network.

l

TETRA’s Status Message (pre-defined text codes) allow for quick messages to be sent over the network.

l

TETRA also supports TCP/UDP protocols on the

• network. Ideal uses include SCADA and Digital I/

O to control pumps, gates, valves, and other industrial controls.

l

With proper connections, TETRA radios can access databases and other external systems.

Fleet Mapping

Good Paperwork è Less Programming Iterations!

l

FHR already has an operational radio network. How do we migrate those conversations, with minimal impact to the end user?

l

Some allocated channels were already “dead” – prune them from the new programming.

l

Each analog channel became a TETRA talkgroup. Because TETRA allows for “folders”, auxiliary channels became talkgroups underneath the main

• channel. Named the talkgroups after the unit numbers

for easy reference.

l

All-call and emergency channel selections were preserved.

Programming the Radios

Sepura’s Radio Manager Software

l

Radio Manager comes in several versions – FHR uses the Server version to allow several programming computers to access programming data simultaneously.

l

Configurations are created in “batches” based upon groups of settings prepared for the radio.

l

USB cables connect the radio to the programming

• computer. Each computer supports up to 32 physical

USB connections at once.

l

Because FHR uses IS radios, they could not take advantage of Sepura’s programming pods.

l

Once the batch is prepared, simply connect the radio, and programming will automatically begin.

Programming the Radios

Test and Re-Program

l

Made an initial program of about 30 radios for technicians and select users to walk around the plant, and comment on system performance.

l

Focused testing with users and features, such as scan groups, to ensure that we had a valid program, and eliminated any oversights.

l

Testing with analog RF gateways, and set audio levels for proper audio response.

l

Tested emergency features.

Maintenance Services & Support

System Care and Reliability

l

Using a VPN, Bay Electronics and PowerTrunk monitor the system for SNMP generated alarms.

l

Many of the TETRA components have IP addresses: TX & RX Systems, ethernet switches, power supply, and Gateways are types of devices monitored over IP, using SNMP.

l

Network Monitoring System (NMS) has visual alarms of troubled equipment, allowing for easy identification.

l

Majority of components are rack mounted, with rails, for easy removal and replacement of defective

• components. Some are even hot-swappable.

l

Base Station Repeaters (BSR) are hot-swappable.

System Care and Reliability 2

l

Sepura releases firmware updates from time to time with new features. When bound to a batch, any radio that is part of that batch will be updated when connected via USB.

l

PowerTrunk releases firmware updates from time to time with new features. Backups of current configurations are made, and may be restored if there is a failure.
