Introduction
The Terms of Reference for TC TETRA approved at ETSI Board meeting #52, May 2005 ([ETSI/B52(05)13 rev.1]) is
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.
• Further enhancements of the TETRA air interface standard in order to provide increased benefits and
optimization in terms of spectrum efficiency, network capacity, system performance, quality of service, and
other relevant parameters.
• The full 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.

6 ETSI TR 102 021-9 V1.1.1 (2009-04)
The TETRA Release 2 standard, incorporating the high-speed capability (TEDS) has just been published. This
high-speed data capability increases the maximum data rate of the TETRA systems from 28,8 kbit/s to over 500 kbit/s,
which has the capability to radically changing the range of data applications available to TETRA users. The current
TETRA PEI standard, EN 300 392-5 [i.18] V1.3.1 is a narrow band interface with limited application handling
capability for the Release 2 type TETRA networks. Hence, an enhanced PEI with a concurrent multimedia capability is
essential to enable access to the system from a range of data terminals (such as laptops, etc.).
The present document provides the User Requirement Specifications for the TETRA Peripheral Equipment Interface
enhancements.
The URS is required by WG3 and WG4 of TC TETRA to guide the enhancement of the current TETRA PEI standard.
Background
The PEI standard which was last updated on August 2007 EN 300 392-5 [i.18], defines a point-to-point configuration
between a TE2 and a MT2 using a sub-set of ITU-T Recommendations V.24 [i.2] and V.28 [i.3]. The V.24 standard
provides list of definitions for interchange circuits between Data Terminal Equipment (DTE) and Data
Circuit-Terminating Equipment (DCE), first agreed in 1964 which is equivalent to a subset of Electronic Industries
Association (EIA) Recommended Standard EIA-232. Beside large voltage swings, limitations in noise immunity and
low reliability of the flow control mechanisms that this standard introduces, the achievable data rate is also a major
bottleneck in wide-band capability of the TETRA release 2.
In order to propose appropriate physical links, an initial study has already been carried out by HW communications Ltd
and submitted to ETSI TC TETRA WG4 as a response to the ETSI's call for STF 314 on TETRA Release 2 PEI [i.4].
The present document, recommends wired and wireless physical link candidates that should be used between a
Terminal Equipment 2 (TE2) and a Mobile Termination 2 (MT2) at the TETRA reference point RT [i.1].
Need for a Physical Link Update
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 the using real-time multimedia applications will be feasible in TETRA.
For example, in table 1, the average required throughput for real-time video is presented. The video resolution and
frame sizes are derived based on ITU-T Recommendation H.264 [i.5]. It is clear that for TETRA2, using outdated
physical link technologies such as EIA-232 which supports maximum data rate of 20 kbit/s is no longer a feasible
option.
Table 1: Average throughput for real-time video transmission
Multimedia service Average throughput (kbit/s)
Real-time video (Resolution/frame)
128 × 96 / 30,9 64
176 × 144 / 15,0
176 × 144 / 30,3 192
320 × 240 / 10,0

A list of applications with minimum required data rates for transmission is provided in annex A.

1 Scope
The present document provides the User Requirement Specifications (URS) for the enhancements of the TETRA
Peripheral Equipment Interface.
The existing TETRA PEI standard has been available since 1998. The TETRA Release 2 standard, incorporating the
high-speed data capability (TEDS) has been published. This HSD capability increases the maximum data rate of the
TETRA systems from 28,8 kbit/s to over 500 kbit/s, radically changing the range of data applications available to
TETRA users. The TETRA users could, from now on, use a range of multimedia applications (with video as a medium)
via TEDS channels. One bottleneck to making full use of this new capability is the restrictions imposed by interfacing
TETRA Release 2 systems via mobile stations only. Hence, a standard HSD PEI with a concurrent multimedia
capability is essential to enable access to the system from a range of data terminals (such as laptops, etc.).
Peripheral Equipment Interface enhancements translated into terms of:
• PEI physical layer aspects;
• Multimedia capability ;
• QoS negotiation
The present document is applicable to the specification of TETRA Release 2 equipment.
The user requirements contained in the present document are described mainly in non-technical terms and are based on
discussions in TC TETRA WG1.
