current status
Current Status
  • 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
Type Approval is ...

Type approval is granted to a product that meets a minimum set of regulatory, technical and safetyrequirements.

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
Operator Vs “Regulator” Perspective
  • Operators essentially want to assure revenue and therefore strive to create/preserve value for their customers
  • While the aim of regulators is to protect the people, the environment and the resources
operators do
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
regulators governments enforce
Regulators/Governments Enforce
  • Essential requirements:

- Safety (LVD, SAR, radiated emissions)

- Electromagnetic Compatibility (emissions and immunity)

- Efficient use of radiofrequency spectrum

  • Other
testing
Testing
  • Conformity

- To essential requirements

- Additional, e.g. interoperability, emergency …

  • Interoperability (Interconnection, interworking, roaming, multiple vendor network)

- Not practical in type approval

- This is a real problem everybody faces

Subject of the discussion

point of reference ce mark approval
R&TTE Directive 1999/5/EC on radio and telecommunications terminal equipment defines a normative framework for CE mark approval and represents a good example and a point of reference for setting a type approval process on a national and international level.

Low Voltage Directive (LVD) – Directive 2006/95/EC

Electro-Magnetic Compatibility (EMC) Directive – Directive 2004/108/EC

radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communication

emc what we need
EMC - What We Need?
  • EMC standards
  • knowledge
  • measurement equipment
  • laboratory
  • good will (intentions)
emc standards
EMC Standards
  • IEC CISPR 16
  • IEC CISPR 22 (EN 55022)
  • IEC CISPR 24
  • EN 300 386 v 1.4.1
  • EN 61000
testing of receivers
Testing of receivers
  • Assuring that the receivers comply with (future!) DVB-T network characteristics
  • Two approaches are proposed:
    • One-time testing at TAL (testing of one type, preparing a report, support in solving problems, database support for Communication campaign)
    • Permanent testing – permanent platform for compatibility and interoperability testing (DVB-T network is a changing environment!) using all approved receivers on the market
mobile communications systems
Mobile Communications Systems
  • 1st Generation ( Analogue, e.g. AMPS, NMT, TACS)
  • 2nd Generation (digital, e.g. GSM, PCS)
  • 3rd Generation (IMT-2000/UMTS)
  • 4th Generation (LTE Advanced)
  • Other (PMR, TETRA etc)

scope of the breakaway session
Scope of the Breakaway session

Decide upon TAL framework

  • Which user eqipment and network elements should be type approved?
  • What test methodologies should be used?
  • Which standards & recommendations should the equipment comply to?
wrap up of the breakaway sessions common
Wrap-Up of the Breakaway Sessions – Common
  • R&TTE Directive is a good point of reference
  • Technology Independence is important
  • 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
issues identified
Issues Identified
  • Counterfeit mobile terminals

- 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

cocluding remarks
Cocluding Remarks
  • An independent testing facility is important for the region.
  • 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
concluding remarks
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
  • Operators to concentrate on interoperability, performance and QoS. Signalling monitoring essential
  • In the beginning, regulators to concentrate on essential requirements

why safety
Why safety?

Electrical products are now the cause of 80% of all fires.

Technology trend leads to reduction and minimization of electronic circuits.

The concentration of elements and concentration of electric power per mm2 is increasing.

Electrical products can fail and may not guarante full life time.

step 1
Step 1

Select the product categories

Choose the corresponding standards

Equip the test laboratory, acquire knowledge and experience

step 2
Step 2

Enforce safety regulations in the country

Determine the penalty

Implement controls on the market

how to build the test site
How to build the test site

Prepare enough place for:

Warehouse for measurement and IUT equipment

Filtering the Internal AC main power and IT network (safety fuse and separate distribution)

Long term tests (tests can take more than 1 month)

Temperature&humidy tests (to assure separate place for noisy test equipment (temperature&humidity chamber))

AC/AC or DC/DC variation

emc definition
EMC definition
  • Electromagnetic compatibility is the ability of a device, unit of a device or system to function satisfactorily in the electromagnetic environment, without the unacceptable electromagnetic disturbances
