Testing for MTCTE (Mandatory Testing and Certification of Telecommunication Equipment) Approval / TEC Telecom Approval
According to the Indian Telegraph (Amendment) Rules, (2003, 2006, and 2023), telecommunication equipment, both locally manufactured and imported, needs to pass certain tests before being sold in the market or implemented in the Indian telecom network.
These tests, determine whether the telecom product complies with the regulatory requirements established by the TEC. TEC, also known as Telecom Engineering Center is the technical wing of the Department of Telecommunications, Govt. of India.
Purpose of MTCTE
The principal purpose of the MTCTE scheme:
-
01
Ensuring that, even if installed in existing networks, equipment will not degrade such networks' performance.
-
02
Ensuring the safety of the end-users themselves.
-
03
Protection of the user and public through regulation of radiofrequency emissions from equipment.
-
04
Ensuring compliance with the applicable national and international standards.
Implementation Phases
-
The MTCTE scheme is proposed to be implemented in phases, where each phase would cover different types of telecom products. Currently, notifications have been issued up to Phase III, IV, and V covering a wide range of telecom equipment. The latest Phase V has commenced from July 1, 2024.
-
Implementation Phases
The latest notified phase of India’s Mandatory Testing and Certification of Telecom Equipment (MTCTE) is Phase VI. It was notified by the Department of Telecommunications (DoT) on 25 February 2025 and became mandatory from 24 August 2025.
Phase VI covers additional telecom equipment, including Cellular Customer Premises Equipment, Fixed Wireless Phones, LAN Switches, IP Security Equipment, and NGSO Satellite Communication Equipment. The applicable requirements are based on the Essential Requirements notified by the Telecommunication Engineering Centre (TEC).
The Telecommunications (Framework to Notify Standards, Conformity Assessment and Certification) Rules, 2025 also provide the updated regulatory framework for conformity assessment of telecommunication equipment in India.
Types of Approvals
Generally speaking, TEC grants three kinds of approvals:
The technology approval will be according to the standards associated with that product. This is called the Generic Requirement or GR, which was given by TEC. Testing is done on-site at the OEM's premises or in a lab environment. This approval requires EMC, Safety, Environmental Testing, etc. Approval under GR is required for bulk purchases by network service providers and under special requirements of government tenders
The IR here in TEC stands for Interface Approval, which is a type of TEC certificate confirming that products adhere to the stipulated interface requirements. Essentially, such certification signifies that the products can link with different networks and devices without a problem. Approval under IR is usually required by end-users in various institutions like schools, colleges, and corporate offices.
The Essential Requirements (ERs) are technical necessities consecutively formulated by the Telecommunications Engineering Center (TEC) for the evolving need for better technology.
The Essential Requirements describe the technical regulations prescribed under this framework which include:
- Average launch power
- Receiver sensitivity
- Wavelengt
- Nominal bit rate with tolerance
- Latency of PON
- MAC address limitations in PON
- MAC-based 802.1x authentication in PON
- Over-voltage and over-current protection
- Password-based authentication in PON
- Maximum bandwidth limiting in PON
All three types of approvals require testing with varied intensity levels, depending on the intended use of the particular product or device
Types of Testing Performed for MTCTE:
Fulfilling the MTCTE criterion requires passing three different tests for telecommunication equipment. These tests are EMC/EMI testing, safety testing, and telecom testing. If a telecom product passes all three tests, it is then eligible to be sold in the Indian market, or imported outside the country.
1. EMC/EMI Testing
Electro Magnetic Interference (EMI) and Electro Magnetic Compliance (EMC) are paramount for Electrical/Electronic/Electro-Mechanical (E/E/E) systems to function normally without causing interference to other devices in close proximity as well as to be immune to disturbances and adverse conditions created by other devices nearby or by nature. For example, if lightning strikes nearby your smartphone doesn’t stop working. That is because it has been tested for EMC/EMI.
Testing Procedures:
In this general process, testing usually involves the following,
-
01
Finding Applicable Standards:
Identifying EMC standards early in the design process helps detect EMI issues, ensure compliance, and reduce redesign costs before testing. It also helps select test methods and meet regulatory standards.
-
02
Pre-compliance Testing:
Testing done in the early stages of design with the aim of identifying possible EMI problems before formal compliance testing. This can greatly increase the likelihood of successful final testing and keep the redesign costs down.
-
03
Formal Compliance Testing:
After the stage of pre-compliance, the device is tested in properly accredited laboratories for compliance with the necessary standards. This can be described as either emissions testing conducted or radiated, etc.
Equipment Used
Testing generally involves multiple forms of specialized apparatus, which include:
Spectrum Analyzers
In general, they are used for calculating the frequency and amplitude of emissions.
Acoustic Panel
Used to control end reflection and noise in the surroundings.
Impedance Stabilization Networks
They are used for conducted emissions testing.
Benefits of EMI/EMC Testing
Increased Reliability
In real-world conditions, it proves that the product provides its expected performance, which increases user confidence.
Safety Assurance
Can prevent disastrous failures that could come from unanticipated electromagnetic interaction.
Cost Reduction
Early design fixes save money by avoiding costly late-stage redesigns and compliance issues.
2. Safety testing
Safety testing is primarily required to ensure the safety of the end user, environment, and the product itself while it is in use. Products are evaluated for proper design, choice of materials, physical layout of electrical components, and all those aspects that are likely to create hazards for the individual and the environment.
Products are tested for excessive heat while in normal operation, excessive leakage currents due to faulty design, use of fireproof or fire-resistant materials, and so on.
For example, if you are using your smartphone for long hours it may produce excessive heat which can then lead to internal circuit damage or even bigger accidents. To prevent these unwanted incidents safety testing becomes immensely important.
Types of Tests Performed
To ensure that telecom equipment is up to the mark and safe to use for the end users certain properties and functions need to be reviewed.
01. Excessive Heat
Telecom products tend to produce excess amount of heat due to prolonged use. This can be prevented using certain precautions. To ensure product safety, it is necessary to take note if the device cooling system is working properly.
02. Excessive Leakage Current
Testing leakage current during the design stage helps identify excessive current flow and potential electrical safety issues. This helps ensure compliance with safety standards and reduces the risk of product failure during final testing.
03.Fireproof Testing
Telecom products have a fireproof system or fire-resistant material installed in them during their development. Safety testing includes reviewing the fireproof system so that any anomaly doesn’t lead to a fire which may cause harm to the end user.
Benefits of Safety Testing
Safety testing is an important process by which the manufacturer and consumer of a product, and then the regulatory body, can have several advantages. Here are the main benefits.
01. Improved Quality and Reliability of Products
Product safety tests help to identify the defects and hazards that might be present in the product before launching it into the market. All products of good quality and those that are performing to the expected standards ensure high customer satisfaction and, as a result, bring in loyalty to the product.
02. Compliance with Regulations
The testing ensures that the products meet the various standards and regulations provided in the industry by bodies like the TEC in India. Compliance mitigates situations like legal tussles, fines, and potential recalls for both the manufacturer and consumers.
03. Risk Mitigation
Through the early identification of safety issues during the development process, companies are better equipped to dramatically reduce the ensuing risks of product failures, which could otherwise lead to both costly product recalls and lawsuits. This is critical for retaining brand reputation and consumer trust.
04. Consumer Protection
Safety testing on products protects consumers from harmful products and assures them that their product is safe when used according to the directions given, creating trust in the brand and marketplace.
05.Competitive Advantage
Products that meet the test of safety impart innovative marketing lines of being reliable and trustworthy, creating a differential advantage in the marketplace. This can also lead to an improved rate of sales and market share as consumers start flowing to brands that emphasize safety.
06. Long-term Cost Savings
Product safety testing, though requiring an upfront expense, can save money by preventing an expensive recall, legal battle, and brand reputation damage down the road. Better performance of products and fewer issues post-launch could happen following feature investment in thorough testing.
07. Improved Marketability
Certification of safe products makes products marketable in a better way, dramatically improving the organization's reputation and credibility with consumers, especially the retailers since most shoppers prefer using products with independent testing and certification.
3. Telecom Testing
Testing of the telecommunication systems, services, and even networks is referred to as telecom testing. It seeks to ensure that all the former work in terms of functionality, performance, and reliability.
Ensuring precise compliance with National and International standards is the main objective of this testing, besides its full compatibility with national telecom networks. To explain further, let’s assume you are traveling to another country.
Types of Telecom Testing are as follows:
- 1. 2W Analog
- 2. Acoustic
- 3. Digital Communications - Electrical
- 4. Digital Communications - Optical
- 5. Signalling
- 6. Protocol Conformance
- 7. Cellular 2G 3G 4G 5G
- 8. RF parameters
