Wireless technologylike Mobile phonesand Fitness followersAnd Medical devicesIt became everywhere. Before manufacturing and selling a wireless deviceIts technology is tested by compliance engineering Laborators to ensure adherence to them Technical standards Organizations created it, including IEEE Standards Association.
in USthe Federal Communications Committee Oversee Systems To all Wireless deviceswhile Food and Drug Administration Focus on Medical technology. The two organizations often work together.

To help Technology companies Get wireless Devices Certified, IEEE member Steve Leo Be established RF safety laboratory in 2023. the StartingIt is based in Catonsville, Maryland, specialized in a specific absorption rate (Go)) Testand nerve Stimulation Test, measurement power density Levels shipping Presses, Surgical toolsand TabletsAnd other products. SAR Test measures quantity RF energy Its absorption Preamble The body is wireless device. Nerve stimulation and Energy density The tests measure the immediate effects on the nervous system of the person.
Liu says that many laboratory clients, who focus on Japanand South KoreaAnd the United States wants to sell its products in Canada And the United States, which has the most strict and most difficult navigation regulations.
The laboratory specializes in ensuring that the wireless devices are specifically safe, and to provide consumers with peace mind.
Not everyone knows that SAR levels are available to the public on FCC Web site.
Many products Developers Do not realize this when merging Wi-Fi or 5G In a device, they need to include shielding against radiation Liu says in their designs to protect humans from excess radiation.
“Emerging and new companies Designers From wireless technology in these countries you do not realize that they cannot only Make “The device is then expected to be able to export it to North America,” he says. “Most of the time, these companies find it only after they have already started market Its products are for consumers, causing them to be kept by customs and border protection. “
If it turns out that the product is not represented with the regulations, the company can face large fines and legal Procedures, the device can be called.
From the test engineer To the startup founder
Leo is not strange to technology Standards And regulations. After graduating with a bachelor degree in Biomedic and Electrical engineering In 2000 from Jones Hopkins UniversityIn Baltimore, join Engineering Laboratory Treaty Cooperation on Patentsin ColombiaMD. The company, now part of componentIt was created to provide organization and test Services To wireless, ElectronicsAnd Wireless and wireless communications Industries.
As a test engineer, Liu evaluated the products Electromagnetic Compatibility, RF Exposure Levels, auditory aid. He also worked as a member in Communications Certificate AuthorityWho evaluates equipment. He even made his way Professional life Peace, and in 2018, he was promoted to the deputy president From engineering, overseeing global compliance.
“Be IEEE member Certainly I paid me. “
“I have pledged more than 4000 companies for companies, including appleand Motorolaand Samsungand SonyAnd RuralLiu says. “It was a really great experience to participate in such large companies and a wide range of products, although we were only a large -scale process of organizational electromagnetic compatibility and the RF safety test.”
in 2020 The company was obtained by Element, which is equipped in London to test important materials, and to test the product qualifications, ScatteringAnd certification services. New presidents mean new culture And a different way to work.
“Although new administration It was supportive and was a good experience, I felt I could not spend time And the energy that I wanted to solve problems, help customers, or Guidance “My employees,” says Liu. After 23 years, he left in 2023 to start his private company, using some of Retirement Smarts. Six of his colleagues joined his project.

How wireless Technology It is evaluated
For a certificate, new wireless products are tested for fixed criteria such as IEEE 802.11 To ensure the requirements for performance and protection. When a company develops a device, it sends technology to Certified test laboratoryWhere the technicians determine whether the product is satisfactory.
If the device is approved, the company can move forward with manufacturing and distribution. If you do not pass a crowd, the company can stop working on it or repair the problem and re -submit the device for certificates.
When the products fail in the test, companies retain institutions such as RF safety Lab appearance Liu says what to do to be dependent.
Although the startup is working with large companies, including Bilkinand GoogleAnd SonyHe says most of its customers are new designers and small companies.
He says: “Many of the first -level companies have a necessary experience to fix the problems that exist during organizational tests, so that they do not face dangerous road barriers unless the development of a new technology.” “But we see that many new designers are not. Conscious From the regulations, so they come to us for help.
He says: “Often they only need to teach them about the regulations and tell the documents they need to provide to obtain a certificate of their devices,” adding that “there are cases in which we need to conduct our tests and assessments to determine how the product can comply with the regulations.”
After evaluating the productive laboratory, it collects a report with its results, including recommendations on how to treat any Failure. Corrective measures can include change levels programming Teachers to influence an antenna behavior.
Liu says one of the most challenging Projects It was a wireless endoscope developed by a group of doctors from Illinois. Light endoscope, flexible Tool camera In the end, it is used to look inside the human body. Although it is small connected via A Wire to a screenthat surgeon It can be displayed during the procedure. and Operating rooms You have many other machines with Wire In addition to endoscopy.
Illinois doctors wanted to reduce the number of wires in operating rooms, so they developed a wireless lapar Offers High -resolution images on the screen.
“They built this interesting device, but they did not know how to obtain a testimony and the impact of the test on the final design,” says Liu.
“Like many companies, the designers were the trick and bought the transmission parts at a low cost of the manufacturer abroad,” he says. “To get an organizational certificate, you should be able to form devices for a specific test purposes, so I and the team had to do a deep diving to find instructions on how the transmission device works and how it was made.” He says he was a particular challenge because the transmission device was not the only part that designers used.
The preparation of the device is ready for certificates requires a lot of cooperation Among the designers, many manufacturers of parts, and organizational agencies.
The process took several months to complete it due to the product High frequencyWhich requires prior instructions with FCC.
“It was a very enjoyable experience and a rewarding project for the team,” says Liu. “We have spent a fun time seeing this project.”
The RF Safety Laborat European Union. It also works to obtain products to meet a global Cyber security Systems.
