Guilin CEKE Communication Equipment Co., Ltd., located in the picturesque Guilin High-Tech District Information Industrial Park, is a private joint-stock enterprise with more than 10-year experience in high-frequency microwave equipment research, design, production, installation, debugging and maintenance. CEKE has a number of senior high-frequency technology R&D experts, first-class instrumentation equipment and 3000 square meters of production and maintenance facilities.

CEKE has a long-term good R&D cooperative relationship with China North Industries Group 206 Institute, Guilin Institute of Automation Technology, Beijing University of Posts and Telecommunication and Guilin College of Aerospace Technology. With maintenance capability of most global communication microwave equipment, mobile base stations, and repeater and wireless bridges, CEKE now undertakes the imported mobile communication equipment maintenance business for more than half of Chinese provinces. With the capability of the research, design, production, installation, system integration and network planning of digital microwave transmission equipment, digital-analog compatible MMDS transmitters and terrestrial digital TV transmission system equipment, CEKE is an industrial leader especially in product and service quality.

Aiming at solving the existing problems in GB terrestrial digital TV networking constructions, CEKE carried out a technical research and successfully launched the first GB terrestrial digital TV broadband transmission system in June, 2008. Now, the same kind of broadband system projects have been opened up and operated in more than 25 stations. 2 multi-channel single-frequency network system, with its mature technology, stable system and significant performance, has become the best DTMB network construction solution.

We are the first company propose BROADBAND concept in China which make our transmitter different from the other suppliers' from the other countries and the other suppliers' in China. With the innovative broadband adjacent transmitting technology, our one set of transmitter can replace several sets of traditional transmitters, realizing the large area coverage with small power and long-distance networking setup, which dramatically reduce the investment of the Digital TV transmission system construction.
