| 14th April 2004 - The key to the integration of all
communications media, and therefore the foundation of
future public safety and security networks, has been announced
by Cogent, the UK operating company of EADS Defence and
Communication Systems. TETRAPOL 2004.IP technology ensures
the availability of all information on the same platform
with identical security standards. Data and voice can
be available wherever public safety and security forces
happen to be. At this month’s BAPCO event, EADS will
present TETRAPOL 2004.lP in actual use (base station,
control node).
TETRAPOL is the world’s most widely deployed professional
digital mobile communications standard, with over 80
systems deployed in 34 countries. TETRAPOL’s standardised
end-to-end encryption, combined with inbuilt security,
provides the highest possible level of protection for
voice and data communications. Cogent’s TETRAPOL
2004.IP proposal has been shortlisted to provide the
new Firelink network for the UK Fire and Rescue Service,
due for implementation by 2007.
With TETRAPOL 2004.IP, Cogent is marketing a new-generation
digital radio system for public safety and security
forces. Based on IP technology (Internet Protocol),
this system provides significant technical and economic
benefits. TETRAPOL 2004.IP was shown in action at this
year’s CeBIT show in Germany.
Key advantages of TETRAPOL 2004.IP include:
• Lower infrastructure and line costs
• A single data network for radio communications
and data systems
• IP telephony is possible over the same line network
• Existing data networks are included, such as
intranets
• Applications are implemented cost-effectively
• Redundancy ensures high operational reliability
• End-to-end encryption provides a high level of
security
• Optimised load distribution during peak times
For digitised voice and data transmissions, the system
utilises existing IP-based data networks (IP backbone)
as far as possible. Voice communications are no longer
transmitted over a separate network, but are instead
compressed and transmitted in the form of IP packets
over the same network as other data. It is therefore
no longer necessary to deploy, maintain and service
several separate networks. Analogue and digital, wireless
and wired networks are readily interlinked by IP interfaces.
The TETRAPOL 2004.IP radio system for safety and security
forces provides all basic services: group communication,
individual and multi-address calls, conference calls,
secure emergency calls, direct mode – as well as
handover and pager. Additional features that are provided
as a matter of course include data transmission with
database access and automatic position fixing with the
help of GPS. The robust radio interface remains the
same, and consequently, so does the advantage that few
base stations are needed. TETRAPOL 2004.IP employs the
latest Vocoder technology to boost voice quality and
voice capacity to unprecedented levels.
