OEM Overview: Production Line: Our equipment comes from the three major operators and leading communications companies, covering mainstream brands such as Huawei, ZTE, and Ericsson. It supports 4G LTE (FDD/TDD) and 5G NR (Sub-6GHz) standards and is suitable for deployment in various scenarios, including macro stations, micro stations, and indoor distribution.BBU (Baseband Processing Unit)Disassembled, cleaned, and functionally tested by a professional team to ensure that core modules such as the baseband board, main control board, and transmission board are fault-free. Supports multi-band network expansion and can be directly connected to existing core networks to meet the needs of medium- and low-load scenarios such as rural coverage and private network supplementation.RRU (Radio Remote Unit)Through power calibration, standing wave ratio testing, and high/low-temperature environmental simulation testing, the RF module output is ensured to be stable, covering the mainstream frequency bands from 700MHz to 3.5GHz, and compatible with 2T2R/4T4R configurations. It is particularly suitable for signal coverage in areas with simple terrain or for short-term communication support during temporary events such as exhibitions or sports events.About quality management: Strict quality control throughout the entire processControlled sourceOnly 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 refurbishmentProfessional 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.
Our Team: Core members have over 10 years of experience in the telecommunications industry, are familiar with the full lifecycle management of base stations, and are proficient in BBU/RRU hardware testing, debugging, and compatibility optimization.The team always solves problems from the customer's perspective. We provide one-on-one service to each customer and are proficient in English and Russian, so there are no language barriers. - Factory Information
