Introduction
The Terms of Reference for TC TETRA approved at ETSI Board meeting #69, November 2008 are to produce ETSI
deliverables (and maintenance thereafter) in accordance with the following requirements:
• The provision of user driven services, facilities and functionality as required by traditional Professional Mobile
Radio (PMR) user organizations such as the Emergency Services, Government, Military, Transportation,
Utility and Industrial organizations as well as Public Access Mobile Radio (PAMR) Operators.
• The evolution and enhancement of TETRA as required by the market with the provision of new services,
facilities and functionality made possible by new technology innovations and standards.
• Further enhancements of the TETRA standard in order to provide increased benefits and optimization in terms
of spectrum efficiency, network capacity, system performance, quality of service, security and other relevant
parameters.
ETSI
5 ETSI TR 102 021-10 V1.1.1 (2010-12)
• The backward compatibility and integration of the new services, facilities and functionality with existing
TETRA standards in order to future-proof the existing and future investments of TETRA users.
Technical Objective
TETRA is one of a number of digital wireless communication technologies standardized by ETSI.
ETSI TC TETRA produces standards and/or adapts existing standards for efficient digital PMR and PAMR voice and
data services, including broadband evolution.
The present document provides the User Requirement Specifications for the TETRA Local Mode Broadband.
Background
Before the initiation of TETRA Release 2, limited attention has been paid to the provision of IP-based wideband
multimedia services in Private Mobile Radio (PMR) wireless networks, such as those used by public safety
organizations in TETRA release 1. However, TETRA Release 2 has changed this by development of TEDS, which
intends to broaden the spectrum of multimedia services offered to TETRA users. As TEDS offers data rates comparable
to that of 2,5G/3G networks, then using real-time multimedia applications will be feasible in TETRA.
This is however only a development which improves fixed trunking network, based on an architecture which assumes a
fixed infrastructure with connections to a central intelligent switch, the SwMI. There are also needs to cover ad-hoc
incident area's with IP-based networks which should support all current services of TETRA (voice, SDS and IP) and
allow applications like sensor data and real-time multimedia applications like video images to be used.
TC TETRA organised a workshop at the TETRA World Congress 2007 to discuss the candidate TETRA enhancement
areas for TETRA Release 2 evolution. The workshop enhancement area are detailed in annex A.
Regarding to Local Mode Broadband, 2 enhancement areas were identified and specified as:
• Local Mode Broadband
Even though the TETRA standard has been enhanced for "wide-band" applications with the introduction of
TEDS, some suggestions have been made to further increase data throughput to match that offered by
broadband data services. For example, some suggestions have been to provide access to broadband services in
certain "hot zones" within a TETRA Voice and Data network coverage area. It was also suggested that "hot
zone" coverage should dynamically increased and/or decreased as required for communication purposes.
• Networking capability for Local Mode Broadband area to Local Mode Broadband area
To further enhance the capability of broadband services in certain "hot zones" as suggested above, there have
also been suggestions to increase "hot zone" coverage by interconnecting different "hot zones" together via the
TETRA Voice and Data network.

1 Scope
The present document provides the User Requirement Specifications for the TETRA Local Mode Broadband.
To improve TETRA on-site communication capabilities, the LMB aims at allowing the intervention teams to
dynamically deploy an ad-hoc wireless network within the incident area, supporting voice, video and data
communication (e.g. sensor-based data such as oxygen, gas, temperature). The ad-hoc wireless network should be made
robust and redundant, securely supporting intervention teams of different disciplines within the same incident area. This
ad-hoc wireless network should be capable of being securely connected, extended and integrated into the into a larger
outdoor TETRA network.
NOTE: Further study may be required before a standardization effort is initiated.

4 Local Mode Broadband (LMB)
4.1 Local
The coverage area of LMB is (in the start-up) limited to "on-site", meaning the "incident area". LMB is an ad-hoc
wireless network that can be deployed anywhere very quickly by "intervention" teams. This means that the equipment
should be small and "simple", not needing people with technical knowledge.
For large scale disasters, the communication in general complies with the "hourglass model".
With the "hourglass model" the following is meant:
• At the incident area, a lot of information is gathered (video footage from different cameras, the different
conversations that are recorded, sensor data, etc.) In general, it is unnecessary and impossible to transmit all
this information to the crisis centre. The crisis centre has no use for individual sensor data, nor for every
individual conversation that takes place in the incident area.
• On the other hand, if the link
