Product Certification Service Organization

1. Introduction to RF radio frequency testing

With the continuous development of radio frequency identification technology (RFID), various wireless products continue to come out, which are relatively popular at present, such as smart home, smart home appliances, etc., are closely related to our lives, and wireless product testing is particularly important. RF is short-term radio frequency. RF is any frequency within the electromagnetic spectrum associated with the propagation of radio waves. When RF current is supplied to an antenna, an electromagnetic field is generated which is then able to propagate through space. Many wireless technologies are based on RF field propagation. Common wireless technologies are as follows:

1.BT/BLE

2.SRD（433 MHz etc）

3.WIFI 2.4 GHz

4.WIFI 5 GHz (DFS)

5.Telecom 2,3,4G (SISO)

6.WIFI 7/6E 8*8MIMO

2. Widely measured electromagnetics - RF laboratory introduction

GCDC RF Laboratory has multiple sets of international leading Bluetooth, WIFI, mobile phone testing equipment (such as WIFI 7 system uses a full set of R&S equipment), 12 years + industry senior technical team, can provide wireless communication products for various electronic companies at home and abroad One-stop services such as testing, certification (CE, FCC, ISED, MIC, RCM, BQB, etc.), GMA, etc.

3. Wireless certification project

Americas: FCC ID, ISED ID certification, etc.;

Europe: CE-RED, UKCA certification, etc.;

Asia: SRRC, NCC, TELECE, KCC certification, etc.;

Others: BQB, QI, Wi-Fi, C-tick, ANATEL certification, etc.
