Regulatory Framework well established
Type Approval in place
Testing limited at the most to field trials
Installation personell has to be certified
Vendors/ distributors have to be rgistered with the
authority
 Problem of counterfeit, sub-standard mobile terminals
 More normative framework still needed
 More enforcement needed

Type Approval is ...
Issued by Sintesio; All rights reserved
Type approval is granted to a product that meets a
minimum set of regulatory, technical and safety
requirements.
Generally, type approval is required before a product is
allowed to be sold in a particular country, so the
requirements for a given product will vary around the
world.

Operator Vs “Regulator” Perspective
 Operators essentially want to assure revenue and
therefore strive to create/preserve value for their
customers
Issued by Sintesio; All rights reserved
 While the aim of regulators is to protect the people, the
environment and the resources

Operators do
 Performance measurement (KPIs, network element
counters, signalling monitoring)
 Implementation / protocol conformance testing
 field trial testing/ drive tests – real environment
 interoperability testing
 load testing
 E2E testing
 Sometimes have test plants / laboratories and are
better placed to conduct some tests

equipment comply to?

Wrap-Up of the Breakaway Sessions – Common
 R&TTE Directive is a good point of reference
 Technology Independence is important
Issued by Sintesio; All rights reserved
 Phased approach is encouraged
 The most problematic issues are to be addressed first
(i.e. user equipment, receivers)
 (Harmonised) standards and their references to be
used wherever possible
www.sintesio.org
1st Interoperability test site endorsed by
Issues Identified
 Counterfeit mobile terminals
Issued by Sintesio; All rights reserved
- cannot be solved by means of TA as those terminals
enter the market illegally
 Questionable quality of network equipment, i.e.
equipment not meeting the declared operation
parametres
- can be solved by menas of TA only to some extent
www.sintesio.org

Cocluding Remarks
 An independent testing facility is important for the
region.
Issued by Sintesio; All rights reserved
 Phased approach encouraged. Start with essential
requirements and then expand the scope based on the
demand
 There is adequate regulatory framework but not
enough normative framework and, consequently, little
enforcement
www.sintesio.org
1st Interoperability test site endorsed by
Concluding Remarks
 Fake phones issue cannot be solved by means of testing and TA
alone if they enter the market illegally, i.e. without TA
 Operators and regulators should equip themselves with detailed
technical (protocols, architecture, testing) knowledge. Ideally by
menas of university courses and other “neutral” sources
Issued by Sintesio; All rights reserved
 Operators to concentrate on interoperability, performance and
QoS. Signalling monitoring essential
 In the beginning, regulators to concentrate on essential
requirements
