4 TETRA World Congress 2007 Future of TETRA
workshop report
4.1 Background
Since the TETRA World Congress in November 2005, several meetings, seminars and workshops took place at which
the future requirements of TETRA were mentioned:
• Various TC TETRA WG and Plenary meetings.
• TETRA Association Members workshop 2006.
• TETRA Association TEDS workshop 2007.
• TETRA Association OUA and PSRG Meetings 2006/07.
Besides new requirements, some areas of performance enhancements were also identified:
• TMO, DMO, TEDS, Packet Data, SDS.
New technology developments in other telecommunication areas also stimulated new user requirements:
• 3G/UMTS;
• WiMAX; ®
• Multi-Mode/Multi-Technology terminals (UMTS - GPRS - GSM - WLAN - Bluetooth ).
As a result of these numerous meetings, TC TETRA felt it appropriate to facilitate a workshop at the TETRA World
Congress 2007 (with the added benefit of important input from outside Europe) to discuss the candidate TETRA
enhancement areas.
ETSI
10 ETSI TR 102 621 V1.1.1 (2008-04)
4.2 Workshop Objectives
The objectives of TC TETRA for the workshop were:
• to provide a clear indication to TC TETRA of the weighting and relative importance of all candidate TETRA
enhancement areas identified;
• to produce a set of User Requirement Specifications (URSs) for use in TC TETRA to initiate new
standardisation work by the technical Working Groups as required;
• to further enhance the portfolio of TETRA standards with new services and facilities, as well as performance
enhancements, to ensure the continued evolution, success and longevity of TETRA as the technology of choice
for traditional PMR user organisations.
4.3 Workshop Methodology
The Future of TETRA Workshop was held on Monday 11th June at the TETRA World Congress 2007, facilitated by
selected members of Technical Committee (TC) TETRA in traditional workshop style.
The delegates received a welcome pack including:
• Workshop Programme;
• List of Candidate TETRA Enhancement Areas.
To ensure the maximum benefit to participating delegates and the TETRA industry as a whole in the limited time
available, a list of candidate TETRA enhancement areas was enclosed for delegates to consider (prior to the workshop)
regarding importance and relevance to their organisation's future needs. This list is available at annex C.
This comprehensive list covers requirements identified from a number of workshops and meetings facilitated by the
TETRA Association and ETSI TC TETRA since the TETRA World Congress in November 2005.
The delegates were asked to complete questionnaire 1 (see annex A) on arrival.
The TC TETRA Chairman provided as part of the introduction and warm up to the actual workshop session an
overview of all the 44 TETRA enhancement areas listed in questionnaire 2 (see annex B):
• TMO Network Enhancements (9).
• DMO Enhancements (14).
• Data Enhancements (6).
• General Enhancement Areas (10).
• Industry Performance Enhancements (5).
The actual workshop sessions were conducted in small groups of maximum nine people. Selected members of
TC TETRA were assigned a workshop group to facilitate, record findings, and present findings to all delegates at the
end of the session. The facilitators described in more detail the candidate enhancement areas and assisted with
completion of questionnaire 2. Each delegate had:
• 100 currency units to spend in each enhancement area groupings to rank and rate importance of the
requirements within the grouping;
• 100 currency units to spend across the five groups to assess the relative importance of the groups.
After the workgroup sessions the findings from each session were presented to all delegates.
A question and answers session was used to refine and agree the main findings from the workshop as a whole.

4.4.11 Delegate breakdown remarks
Analysis of the profile of the attendees shows that the transportation sector was under-represented as were the specialist
users of the TETRA Direct Mode Operation (DMO) standards.
ETSI TC TETRA is approaching the TETRA Association to use their resources and contacts to reach these parts of the
user community.
4.5 Result representation
4.5.1 Global overview results
The global overview results (clause 5, figures 11 to 16) are a graphical pie-chart representation of the average of the
expenditure of all workshop participants per questions 1 to 6 from questionnaire 2 and the questions from
questionnaire 1.
4.5.2 Weighted results and weighted comparison results
The weighted results (clauses 6 to 13, figures 17 to 59) and the weighted comparison results (clauses 14 to 16,
figures 60 to 74) are calculated by averaging the multiplication of the spend value in a certain enhancement
(enhancement area from question 1 to 5 from questionnaire 2) by the spend value of the relative importance of the
enhancement group to which the enhancement area belongs (question 6 from questionnaire 2) for the considered
respondents segment.
The charts use bar representation of the average and the probability interval. The average is the value where the colour
of the bar is abruptly changing (from yellow to blue). The bar indicates the 68 % probability interval i.e. arithmetic
average plus and minus one standard deviation. In the probability interval calculation it was assumed that the
distribution of the answers follow the normal (Gaussian) distribution. The probability interval is a function of the spread
and number of the answers for that specific enhancement area. So it is an indication on the agreement, i.e. a narrow
interval, or disagreement, i.e. a wide interval, on the relative importance of an enhancement area.
ETSI
17 ETSI TR 102 621 V1.1.1 (2008-04)
In some cases the scale of the relative importance was selected for an easier comparison so that some interval may
exceed the scale and the actual upper interval is indicated by a number next to the corresponding interval bar.
For the weighted comparison results (clauses 14 to 16, figures 60 to 74) three times two pairs of respondent segments
are compared. These pairs are chosen because they are supposed to have sometimes opposite requirements. By
analysing the differences and similarities between these supposed to be opposite segments, more knowledge can be
gained for specific enhancement requirements of one of the two segments. In the charts, the first segment is always
represent by the top bar for the specific enhancement area. The enhancement areas are sorted in order of averages of the
first segment.
