Wireless Coverage Products and Services
Wireless Coverage Products
The company produces a range of wireless coverage products, including repeaters, trunk amplifiers, base station amplifiers, tower amplifiers and related accessories. The primary functions of wireless coverage products are to extend wireless coverage and improve radio signal quality. Its wireless coverage products support various transmission protocols, including CDMA, GSM, PHS and digital trunk communications. The company has completed its research and development for various 3G network coverage products.
In 2006, the company’s TD-SCDMA repeaters and trunk amplifiers passed the joint trials conducted respectively by various base station manufacturers, namely, Datang Mobile Communications Equipment Co., Ltd, China Putian and TD Tech, Ltd. The company uses its wireless coverage products in three primary function areas: indoor distribution, outdoor coverage and base station coverage extension.
Indoor Coverage: The company’s indoor coverage products support various transmission protocols, such as CDMA and GSM networks (1,800 MHz and 900 MHz), PHS, TD-SCDMA and other networks. The company also provides point of interface, or POI, products that are capable of supporting multiple protocols simultaneously, which offers coverage platform solutions in subways, indoor stadiums and other indoor facilities.
Outdoor Coverage: The company designs its outdoor coverage products to provide wireless coverage in specified geographic and topographic regions. The company’s outdoor coverage products are typically used in areas, such as ighways, railways, subways and tunnels.
Base Station Coverage Extension: The company’s base station coverage extension products are typically attached to base stations. It uses base station amplifiers and tower amplifiers to extend a base station’s coverage in all its surrounding directions or to improve its coverage distance in designated directions. The company’s base station coverage extensions are typically used in remote outdoor environments, such as rural regions, seashores and mountainous areas.
The company’s integrated design, engineering, and production processes allow the company to provide wireless coverage services to its customers.
Design Services: At the outset of each project, its design team implements a series of tests to evaluate its 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.
Installation of Wireless Coverage Products: The company uses approximately 100 contractors across China, all of whom are independent third parties. The company tests the products at the customer’s premises.
Project Warranties: The company provides service warranties to its wireless coverage customers for a period typically ranging from one to three years following the final inspection of its wireless coverage products. During the warranty period, the company agrees to repair or replace defectively installed products and to provide other warranty services to its customers, such as a centralized Internet-based system to monitor the performance of its wireless coverage products and regular on-site inspections of its installed wireless coverage products. In addition, the company provides other warranty services such as online technical support and telephone hotline support to its customers.
Selected Completed Projects
The company completed 10,539 projects in 2006.
RF Parts and Components
In addition to the provision of wireless coverage products and services, the company also develops, manufactures and supplies RF parts and components for base stations and repeaters. RF parts and components are essential building blocks for all forms of wireless communication products. RF parts and components can be classified into active and passive modules. Active modules contain electronic components, such as transistors and diodes and require external power to operate. Passive modules do not contain any electronic components. They rely on a combination of integrated circuits and magnetic fields emitted by their components to function. The company produces both active and passive modules.
The company’s active modules include RF power amplifiers, low-noise amplifiers, frequency-hopping modules and high-stability/low-phase noise vibrators. The company’s passive modules include filters, duplexers, multi-frequency splitters, combiners and couplers and antenna.
