iPhone Repair Radio Wave Characteristics 'Vary by Individual Device' ── Smart Doctor Pro Osaka Shinsaibashi Discloses Quality Verification Process Using Radio Wave Tester CMW500
Smart Doctor Pro Osaka Shinsaibashi Honten has unveiled its quality verification process for iPhone repairs using the Rohde & Schwarz CMW500 wideband radio communication tester. The company found that radio characteristics vary significantly by individual device and software updates, suggesting that design-based certification alone is often insufficient to ensure compliance with radio laws in real-world devices. They also disclosed the significance of their 'diagnosis fee system,' operated under ISO9001:2015 certification, from the perspective of an independent repair business.

Smart Doctor Pro Osaka Shinsaibashi Honten (operated by CREA Inc. / Headquarters: Nishi-Shinsaibashi, Chuo-ku, Osaka / Representative Director: Junichiro Koga), a smartphone repair business, announced on May 13, 2026, the details of its verification process utilizing the 'Rohde & Schwarz CMW500' wideband radio communication tester for repair quality management. Based on measurement data accumulated from approximately 60,000 repairs annually, the company has continuously confirmed that 'radio wave characteristics fluctuate due to software updates and individual differences, even for the same model.' They state that there are situations where it is difficult to guarantee compliance with radio laws for actual devices through design-based certification alone. Concurrently, the significance of their 'diagnosis fee system,' operated under ISO9001:2015 certification, is also disclosed from the standpoint of an independent repair business.
**Communication Quality Verification of Repaired Devices Using Rohde & Schwarz CMW500 Radio Wave Measuring Equipment**
**■ Background: Current Status of Radio Law and Compliance in the Repair Industry**
With the expansion of the smartphone market, the number of businesses providing repair services has also rapidly increased. However, the initiative to objectively verify the communication quality and radio wave characteristics of repaired devices using measuring equipment is not necessarily widespread across the industry.
Smart Doctor Pro is an independent repair brand that pioneered smartphone repair services in Japan compliant with the Electrical Appliances and Materials Safety Act (PSE) in 2009. CREA Inc., the current operating company, was established in September 2011 and continuously operates a quality management system as a registered repair business with the Ministry of Internal Affairs and Communications and an ISO9001:2015 certified company.

**■ Overview of the Disclosed Verification Process**
The 'CMW500' manufactured by Rohde & Schwarz, which our company utilizes for repair quality management, is a wideband radio communication tester standardly used by telecommunication equipment manufacturers and certification bodies worldwide.
Our company operates this equipment as part of 'process quality control,' which involves periodically verifying the quality of the entire repair process, rather than individual inspections for each repair. Specifically, representative samples are measured at timings such as parts lot changes, repair method revisions, and assembly process changes, with the aim of statistically understanding the impact of the repair process on the device's radio wave characteristics.
This enables us to confirm that repaired devices maintain communication quality equivalent to that at the time of manufacturer shipment, not just by confirming design specifications, but by verifying the behavior of the actual device.

**■ Our Official Statement**
"Regardless of how the system was established, it has been confirmed that the radio wave characteristics of actual devices fluctuate due to software updates and individual differences. Even in our measurement environment, differences are observed depending on conditions for the same model. Therefore, design-based compliance alone does not guarantee compliance in terms of state." ── Smart Doctor Pro Quality Control Department
This statement is based on approximately 60,000 annual repair achievements and continuous measurement data using the CMW500, casting light on how communication quality management should be in the repair industry.
**■ 'Diagnosis Fee System' under ISO9001:2015 Certification**
In some parts of the repair industry, service providers charge only if the repair is successful. In contrast, our company, based on the ISO9001:2015 certified quality management system, adopts a 'diagnosis fee system' where an accurate diagnosis is performed before commencing repair, and an appropriate estimate is provided based on the diagnosis results.
This system is designed to prioritize accurately conveying the device's condition and repair prospects to customers, considering the technical complexity of modern smartphones (especially NAND memory and CPU pairing, integrated logic boards, and advanced waterproofing structures). Based on the diagnosis results, we also offer customers the option 'not to proceed with the repair,' achieving highly transparent operations.
**ISO9001:2015 certificate obtained by CREA Inc. (Scope: Import and repair of smartphone parts)**
**■ Customer Evaluation and Inbound Support Achievements**
As of May 2026, our company has received a cumulative total of 424 reviews with an average rating of 4.8 (out of 5). Additionally, to meet the same-day repair needs of foreign tourists visiting Japan, we have established a 9-language support system and serve approximately 2,000 overseas customers annually.
**■ Future Outlook**
Our company will continue to disseminate transparent information as an independent repair business and expand the scope of utilization of quality verification data using CMW500.
