IZUMI COMMERCIAL COMPANY LIMITED

We are a communications equipment supplier, providing Base Station Control Unit (BBU) and Remote Control Unit (RRU). With a professional technical service team, we are committed to providing high-performance and highly reliable communication solutions for every customer. Before each product leaves the factory, we strictly follow the international inspection standards, and deliver the products on time and provide spare parts in time.

Our Service

Why choose us? Three core values

Cost advantage:

The price of equipment of the same model is only 30%-50% of that of brand-new equipment, helping customers reduce initial procurement costs, especially suitable for projects with limited budgets such as rural revitalization communication coverage and temporary expansion of private networks.

Flexible compatibility:

Supports "mixed networking" (e.g., new BBU + used RRU, compatible configurations across different brands), provides free compatibility testing services to avoid equipment idleness and waste.

After-Sales Service:

All equipment comes with after-sales service, and core module failures are supported with replacement.

History

Established in 2008,we have consistently prioritized clients,offering cost-effective solutions and fostering long-term partnerships for mutual success

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 Tour

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.

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.
