SCADA OVER TETRA
Patrick Colling Managing Director of CoCo elements
Deployment of the FO network in close collaboration with third parties relating to the design/engineering,
implementation, commissioning and maintenance of the network.
Design, implementation and monitoring of a transmission architecture based on PDH-SDH-IP/MPLS
technology. Looking for synergies for data transmission depending on requests (bandwidth, data
security...)Transmission between SCADA and RTUs using legacy protocols (TG065, TG80x, SEAB-1F) and
standard protocols (IEC-104, IEC-101).
Design of a cybersecurity policy based on firewalls, authentication, access control.
Design, engineering, installation and commissioning of smaller projects (ex: protocol converters SEAB-1F
to IEC-104; signal converters TTY to RS232).
Define and forecast annual budget for Communication Infrastructure services (OPEX and CAPEX)
Deployment of a multi-services architecture network.
Project Manager at Creos Luxembourg, of a TETRA network covering needs for critical voice communication
and data transmission, especially to the MV level.
Communication Infrastructure at utilities
The Communication Infrastructure aims to
secure Data Exchange of the Grid applications:
PDH/SDH, IP/MPLS, MPLS/TP, SCADA,
RTU’s, Power Quality Management, TETRA,
Smart Metering, Teleprotection, Current
Differential Protection, Video surveillance,
VoIP, Fiber Optic Network…

The availability of near real time information at the customers, and at strategic distribution assets (like MV/LV
transformers and LV lines), provides valuable information such as load and voltage at those points, events
(indicating among others: continuity of supply, neutral cut, fraud, etc), earth leaks, serial faults, etc. The massive
information available (spontaneous or by request) is analyzed and presented to the users in a synthetic way, in order
to understand network status and identify critical situations that require immediate action.
Utilities need access to radio frequency spectrum because they have increasing communications needs for
operational reliability, safety and security…
Severe weather caused last Friday in Belgium for power outages and flooding. Nevertheless, the TETRA network
continued to work flawlessly.
This proves that even with elimination of electricity, the TETRA network continues to function properly.
Feb 2016
Strong wind causes power outages in several places in Norway that led to outages of the TETRA network.
In total there are around 1,200 stations on the TETRA network and 25 base stations were out of operation.
Outages were mainly due to power failures and breach of transmission lines to the base stations. With regard to the
transmission lines, the emergency network depends on the robustness of the power supply and leased
telecommunication lines from subcontractors….
Feb 2016
Public Safety bodies around the world are looking to deploy networks using the LTE standard, to replace aging
infrastructure based on TETRA, PMR, and P25. LTE has much to recommend it in this role, but “standard” LTE
systems lack key functionality that is required to replace the legacy public safety networks.
LTE Networks are usually owned by commercial operators and service providers and are driven by business
models.
At utilities a communication infrastructure never has to be a business model

Drivers
- Voice (e.g. replacing existing analogue systems)
• Terminals, fixed devices
• Redundant infrastructure
• Coverage
- DATA (monitoring and control)
• SCADA –RTU
• Windmill/Photovoltaic – Parcs
• E-Cars
• Leased Copper lines out of support
• Smart-Meters (e.g. Concentrators)

The
Case
Luxembourg is connected to the German grid
(Amprion) via two double HV lines
Transport Grid
High Voltage (HV) : 220 kV et 65 kV
Distribution Grid
Medium Voltage(MV) : 20 kV
Low Voltage (LV) : 230/400 V High Voltage to High Voltage from 220 kV to
65 kV
– 6 stations
High Voltage to Medium Voltage from 65 kV
to 20 kV
–48 stations over Luxembourg
Medium Voltage to Low Voltage from 20 kV
to 0,4 kV
–2 428 stations
The Gas Network from Creos is
interconnected to the German, French
and Belgian Networks.
Transport Network
• High Pressure (HP) : 60-80 bar
Distribution Network
• Medium Pressure(MP) : 0,1-1 bar
• Low Pressure(BP) : 0,01-0,1 bar
The Network - Backbone for IP/MPLS
- Backbone for the TETRA network - Sites for TETRA base stations
Technologies analyzed
• DMR capacity problems, no spectrum in Luxembourg available
• SATELLITE the most cost intensive solution
• TETRA supported by spectrum availability from the regulator
• WIMAX not really covering voice
• GPRS too dependent from Telco operator, not very reliable
• CDMA 450 a favorite, but no spectrum in Luxembourg
• LTE too expensive, no spectrum in Luxembourg

Request for Proposal (1)
• 500 Terminal (Handheld)
• 50 fixed devices
• 3000 Modems
• Coverage:
• 100% for the Modems
• 1m above ground for handheld
• indoor penetration via gateway functionality
• complete redundant infrastructure
10
Request for Proposal (2)
• TEA1 (no security class specification)
• OTA (over the air upgrade, TETRA modem e.g.)
• Voice recording
• LAN interface to SCADA
• Serial interface to SCADA (IEC 101)
• HV Stations mostly to use as BS
• Time line for Network 2014-2015
• Time line for modems 2015-2018
11
Analyzing Bids • 5 bidders
• 4 System Integrator/ 1 Vendor
• 5 different System provider
• 3 same Terminal provider
• 3 same Modem provider
• extreme differences in coverage planning
• extreme differences in number of carriers
• extreme differences in number of BS
• extreme pricing difference
12
The decision • Network (SEPURA Systems)
• BS -> 70% inside HV station
• Best price/quality relation
• Terminal (SEPURA via SEPURA Systems)
• Best price/quality relation
• Adaptive accessories
• Modem (PICIORGROS via SEPURA Systems)
• Absolute the best integrated solution (RTU)
• Order dependent from a PoC
