Our Services

Our integrated design, development, engineering and production processes allow us to provide wireless coverage solutions to our customers. The services we provide include:
Design and Development Service. At the outset of each project, our design team implements a series of tests to evaluate our customer’s specific network coverage on the project site and identify any network deficiencies. These tests include magnetic environment, base station signals and coverage tests. Once the testing is complete, our design team, working closely with our sales and marketing team, which is familiar with the customer and its needs, prepares and submits a detailed design plan to our customer for the proposed wireless coverage solutions. This process allows us to develop solutions that are tailored to each specific customer’s requirement. Upon finalization of our design plan, our customer confirms their instructions to proceed with the equipment development, engineering and installation.
Installation of Wireless Coverage Equipment. Once we receive confirmation for the design plan from our customer, we proceed with the equipment development and engineering, and begin discussions with the property owner or the manager of the building, in collaboration with our customer, to arrange the installation of the wireless coverage equipment. After we engineer, produce and assemble the equipment, we deliver it from our production facility to the project site. In general, we hire third-party contractors to carry out the installation under the supervision of our project design and technical service team. We use more than 40 contractors across China, all of whom are independent third parties. After completion of the installation process, we test the equipment at the customer’s premises to ensure that they function properly before our customer issues the completion certificate. After the issuance of the completion certificate, the inspection of our installed wireless coverage equipment starts by which our customer performs a further testing of our wireless coverage equipment.
Project Warranties. We provide service warranties to our wireless coverage customers for a period typically ranging from one to three years following the final inspection of our wireless coverage solution. During the warranty period, we agree to repair or replace defective installed equipment and to provide other warranty services to our customers, such as a centralized Internet-based system to monitor the performance of our wireless coverage equipment and regular on-site inspections of our installed wireless coverage equipment. In addition, we provide other warranty services such as online technical support and telephone hotline support to our customers. Our policy is to respond to our customers within 24 hours after receipt of any technical support request.
