Quality Control

Strict quality control throughout the entire process

Controlled source

Only normal equipment from operators is recycled (not faulty or scrapped items). Each piece of equipment comes with its original network registration number and retirement record, enabling traceability of its service life (average service life of 3-5 years, with a remaining service life of over 5 years).

12-step inspection process

From外观 inspection, module power-on testing, baseband processing capability verification, to RF power calibration
High/low-temperature stability testing (-20°C to 55°C)
72-hour full-load operation stress test

Ensuring device performance meets over 85% of original factory standards, accompanied by detailed inspection reports.

Compliant refurbishment

Professional repairs are performed for issues such as interface wear and aging of the housing, and aging capacitors and other wear-prone components are replaced to ensure the device meets physical condition standards, without affecting installation or long-term use.
