SRRC, or the State Radio Regulation Committee, is a mandatory certification required by the National Radio Management Committee of the Ministry of Industry and Information Technology of China. All wireless products sold within China must obtain certification, commonly referred to as SRRC certification, which involves approval of the wireless transmission equipment model.
SRRC Document No. 129:
Document No. 129 introduces various interference avoidance technical requirements for wireless transmission equipment, including “pre-transmission scanning," “monitoring and avoidance," and “Medium Utilization (MU)" for equivalent occupancy rate.
a. “Pre-transmission scanning" and “monitoring and avoidance" mechanisms involve monitoring and listening to the wireless channel before or during signal transmission. By setting appropriate detection threshold levels, the channel’s occupancy status is determined to select an idle channel for access.
b. The “equivalent occupancy rate" mechanism requires wireless transmission equipment to self-adjust based on parameters such as “Duty Cycle" and “transmission power," ensuring the “equivalent occupancy rate" remains at a lower level (not exceeding 10%).
1. Certificate Validity Period: Enforced from October 15, 2023. During this period, both old and new policies can be applied. Certificates obtained under the old regulation (Document No. 353) are valid until December 31, 2025. However, certificates obtained by complying with the requirements of Document No. 129 will be valid for 5 years.
2. Sample Requirements: 2.1 The quantity of conducted samples prepared according to the old regulation remains unchanged: 5 samples. 2.2 The major change introduced by Document No. 129 is the addition of interference avoidance technical requirements. The interference avoidance test items include: 1. Maximum channel occupancy time 2. Minimum channel idle time 3. Minimum silence period duration 4. Detection of unused signals 5. Detection threshold 6. Short control signal duty cycle 7. Equivalent occupancy rate.
You will get a brief understanding of WPC-ETA certificate (India) and how it relates to Raytac low energy Bluetooth module and how it helps you entering Raytac Bluetooth module into India by passing through importing and Customs clearance procedure way efficiently.
There are some types of ETA certificate categorized by the spec of your wireless transmission product (Bluetooth/Wifi/RFID and by device using frequency spectrum).
Hereafter we’re talking about the WPC-ETA compliance regulation to specifically on “Raytac’s low energy Bluetooth module.”
Outline of the article:
What is WPC Certificate/Equipment Type Approval (ETA) in India?
Raytac Bluetooth module applied to WPC-ETA Regulation Category
What is essential to get the ETA-SD license (ETA Approval)?
How the ETA-SD license works during importing process
A. What is WPC Certificate/Equipment Type Approval (ETA) in India?
The WPC (Wireless Planning & Coordination) is the broadcasting authority and is part of the Ministry of Communications and Information Technology in India.
Products with radio and/or wireless functionality imported or manufactured or marketed in India are required to have an Equipment Type Approval certificate (ETA certificate) from the Wireless Planning and Coordination (WPC India) Wing of the Ministry of Communications of the government of India. This includes product with Bluetooth, wireless local area network access technology (Wi-Fi), small digital radios (Zigbee), and radio frequency identification (RFID) and else more. The WPC-ETA certificate is required for anyone who wants to do wireless device business in India.
B. Raytac Bluetooth module applied to WPC-ETA Regulation Category
–ETA Through Self Declaration (ETA-SD License)
To specifically recognize what is the compliance regulation of equipment applies to Raytac Bluetooth module, we can be assured with our Bluetooth module spec located within “De-licensed Frequency Band list” , 2400-2483.5MHz / Limit with 10mW EIRP / Use of low power and very low power short range radio frequency device for Non-Specific Short range device, from the following chart which was released from WPC authority.
Once we confirm Raytac Bluetooth module spec is operated in De-License Frequency Band with low transmission power, at the mean time making sure the device is exempt from import license as per Import Policy of DGFT (Directorate General Of Foreign Trade), Ministry OM ETA-WPC-Policy-2018-19 dated 26th February 2019, free from EXIM Policy of DGFT, Raytac is granted to apply for “ETA Through Self-declaration” application procedure which was enabled by SARAL SANCHAR Portal of DoT on 12th April, 2019.
Here’s Raytac’s ETA through self-declaration (ETA-SD license) of module MDBT50 certified by WPC authority. (Please refer to the following image)
C. What is essential to get the ETA-SD license (ETA Approval)?
After getting idea of what ETA-SD license means to Raytac low energy Bluetooth module business, we need to get ready of the following points for applying the ETA Approval (ETA-SD License)
Applicant must be India manufacturing or authorized Indian representative
Making sure product exempt from import license
Making sure product working in the de-licensed frequency band
Wireless RF test report conducted by accredited laboratory
Details of Accreditation laboratory & Accreditation certificate issuing authority
Authorization letter
D. How the ETA-SD license works during importing process
Once ETA through self-declaration is generated for a model, subsequently it may be utilized by other person(s) for import/usage purpose in India. It is not necessary the importing agent/manufacturer is same party to the applicant of the license.
Question: How to import products falling under the category of ETA through Self-Declaration? Answer: Such category of product(s) may be imported by submitting an undertaking to the customs along with ETA-SD License without additional payment.
The ETA-SD license remains valid and NO renewal is needed until the technical parameter/design of the device is modified or altered.
Generally speaking , India doesn’t follow Modular policy nor Non-Modular policy. It determines how you proceed WPC-ETA certificate by product type (Semi-finished & End-product) and product technical spec (Frequency spectrum & Max output power). For instance: When the product is manufactured in India and its RF module(s) having ETA certificate is/are fitted inside it without any modification/alteration; then NO separate ETA is required for such finished product during import process. However, if finished product(s) are manufactured outside India, then ETA is required for each product before its import.
For the product which does not fall under De-Licensed frequency band and exempt from import license, WPC/ETA Certificate shall be obtained by routine proceeding to the concerned RLO ETA certificate. Both ETA (RLO) certificate and Import license shall be submitted to Customs during importing process whereas ETA-SD license Raytac module certified is exempt from import license that is way easier to proceed.
