Absorption Ratio Test SAR Test Electromagnetic Wave Energy Absorption Ratio Of Mobile Phones Or Wireless Products

Absorption Ratio Test (SAR) Electromagnetic wave energy absorption ratio of mobile phones or wireless products

Introduction to SAR testing

It is defined as: under the action of external electromagnetic field, an induced electromagnetic field will be generated in the human body. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate current, resulting in the absorption and dissipation of electromagnetic energy. SAR is commonly used in biological dosimetry to characterize this physical process. The meaning of SAR is the electromagnetic power absorbed or consumed by unit mass of human tissue, in W/kg.

The LCS SAR laboratory supports SAR testing of mobile devices such as mobile phones, data cards, tablets, and walkie-talkies. The test frequency range is 300MHz-6GHz, including 2G, 3G, 4G, WIFI and other communication standards.

Due to the widespread popularity of radio equipment (such as mobile phones) around the world, more and more government departments, telecommunications regulatory agencies, etc. require that electromagnetic wave radiation be reduced to an appropriate level.
In order to meet the urgent needs of mobile phone manufacturers, Beidian Testing has introduced an advanced mobile phone electromagnetic wave energy absorption ratio (SAR) test system. This test system fully complies with the SAR standard requirements of IEEE/IEC/EN and American ANSI. It is fast, accurate, safe and efficient. It is also the most widely used and widely recognized SAR test system in laboratories. The test frequency range of this system reaches 6GHz, and it can conduct certification tests for GSM, CDMA, WLAN and other types of products (not limited to mobile phones).

About Us

Shenzhen LCS Compliance Testing Laboratory Ltd., abbr. for LCS, was founded in 2004 in Shenzhen, LCS is now growing into an independent comprehensive third-party institution which focuses on test & certification. Profound technical background and diligent working attitude decided LCS with an outstanding high starting point from the outset，pioneering spirit and consciousness of keeping pace with the times which predestined the thoroughly tempered course of LCS.

Our Labs

LCS Founding Members have engineering background and had gradually built up Safety Lab, EMC Lab, RF Lab, SAR & HAC Lab, Reliability Lab, Lighting Electrical Lab, LED Lighting Performance Lab, Energy Efficiency Lab, Electronic Cigarette Testing Lab, Chemistry Lab, BQTF, Environmental and Occupational Evaluation Lab, Battery Lab, Toy Lab, Textile Lab, Food and Food Grade Material Lab. The establishment of our comprehensive labs ensure our test and certification scope covers almost all fields, such as Reliability and Safety test, EMC test, Chemical Hazardous Substances test, Material Analysis, Food Contact Material test, Bluetooth Test & Certification, Environment and Occupational Health, Performance test of spare parts of Automobile and so on.

Authorization

Moreover, LCS won many authorized qualifications both domestic and overseas. LCS is recognized as IEC/ISO17025 laboratories accepted by CNAS and NVLAP, accredited by CPSC, CMA, accredited for CQC, ISTA, CBTL, SASO, SABS. Meanwhile LCS become laboratory authorized by TUV, BQTF issued by the SIG. LCS had also signed cooperation agreements with FCC, ISED, ETL, CEC, UL, E-Mark, CETECOM, KTC, SAA Approval and many other authoritative institutions, hence we can provide our clients with efficient and professional service for product test and certification.

Experience

Our RF experience ranges from WLAN (802.11b/g/n/a/ac), Wi-Fi 6E, Bluetooth (802.15.1), ZigBee (802.15.4), Z-Wave, UWB (802.15.3), WiMAX (802.16), SRD, DECT, RFID, NFC, GSM, WCDMA (+HSDPA/HSUPA), LTE, 5G (NR/VoNR/eMTC/eMBB/URLLC),UHF/VHF, WHDI, AM, FM, DAB, DVB, GPS, GNSS, COMPASS, GLONASS and more. The products we are mostly working with are basestations, client adapters, laptops, cordless phones, baby monitors, cellulars, radars, sensors, scanners, receivers, immobilizers, remote controls, etc. Modern products incorporate not often one, but a variety of co-existing technologies.
