Motivation

Study Group 5 has produced a number of EMC recommendations and handbooks which provide key information to the telecommunications industry on the:

• electromagnetic environment around telecommunication equipment;
• expected worst case levels impacting equipment in this environment;
• appropriate laboratory test levels for this equipment to guarantee performance quality;
• mitigation techniques.

This question will provide new EMC Recommendations for telecommunications and will determine when the existing documents need updating or amending and ultimately provide guidance on when they can be deleted.

This work contributes to a reduction in climate change by developing specifications that allow equipment to operate within this environment without disturbance. The availability of such equipment avoids the unnecessary manufacture and distribution of equipment that is used to replace existing equipment thought to be faulty. It also reduces the subsequent engineer visit required to resolve the ongoing issue.

The following Recommendations, in force at the time of approval of this Question, fall under its responsibility:

• K.18, K.23, K.24, K.34, K.37, K.38, K.42, K.43, K.48, K.49, K.62, K.63 and K.76.

Question

This question will provide new Recommendations and will review existing K-series EMC recommendations to ensure that they remain accurate and appropriate to the telecommunications industry and environment. It will ensure that changes in the environment or in technology (for example the introduction of new radio systems) will produce an update to ensure that these documents remain current and valid. As part of its output this question may highlight further areas of study (for example new technologies) for other questions.

This question may recommend further areas of study.

Study items to be considered include, but are not limited to:

• Requirements above 1 GHz,
• Update requirements below 150 kHz,
• The inclusion of specific test methods and operating conditions,
• The specific inclusion of RF active devices,
• Calculation method for induced voltages in K.18;
• Immunity recommendation for xDSL;
• EMC requirements for electric and electronic equipment with telecommunication port, both wireline and wireless port (e.g. TV, refrigerator, home controlling);
• Lightning immunity test method (improve surge tests);
• Consideration of new EMC environmental characteristics.

Tasks

Tasks include, but are not limited to:

• A new recommendations related to EMC requirements at high frequencies (1-6 GHz) for telecommunication equipment
• A new recommendation related to EMC requirements at low frequencies (9-150 kHz) for telecommunication equipment.
• A new recommendations related to EMC requirements for Next Generation Network equipment
• Maintenance and enhancement of existing Recommendations to cover new environments.
