Terrestrial digital TV planning & design ability
Based on a wealth of long-term engineering expeirence of networking construction; under the strong support of professional institutions; with the assistance of professional design software and detailed and accurate geographic data, CEKE formed a good terrestrial digital TV netword planing and design capabilities.
- CEKE has built a long-term and 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.
- CEKE has passed the international ISO9001 Quality System Certification, and the digital television transmitter has passed the State Administration of Radio Film and Television (SARFT), SRRC,AQSIQ certification.
- CEKE was awarded “Guilin National Microwave and Optical Communication High and New Technology Industrialization Base” by the Ministry of Science and Technology in 2011.
- Multi-channel adjacent channels transmitting
One set of the wide frequency band transmitter can transmit any numbers of the frequency channels between 80MHz and 100MHzfrequency bandwidth.
- Low noise, low power, low power consumption & high efficiency
Low noise design and low equipment noise figure(N≤6 dB) greatly increase effective transmitting power.
- Module structure, ease to maintenance
Module structure design and integrated unique power module (hot-plug design) are easy to on-site maintenance without the power combiner. All transmitting TV programs still can be normally transmitted with hot-plug design, if one of the power amplifiers failure.
- Full power specifications to meet the requirement
The equipments meet 200mW ~ 2000W different power level transmitting coverage requirements.

1. More than 14 years of experience in high-frequency microwave equipment research, design, production, installation, debugging and maintenance.
2.With sophisticated research and development capability and cooperated with China North Industries Group 206 Institute, Guilin Institute of Automation Technology, Beijing University of Posts and Telecommunication and Guilin College of Aerospace Technology. Provide the most advanced products.
3. With a full range of large-scale terrestrial digital television networking products, we are sure that you will find what you need in setting up a large area terrestrial digital TV transmission coverage network
4. Providing comparative price and high quality products, so far, our company have cooperated with many customers from over 50 countries and gained good reputation at home and abroad.
Q1. Could you please introduce which countries have you been cooperated with?
A1: Our products have been widely sold both at home and abroad, and our main customers come from five continents about 30 countries, such as Uruguay, Chile, Bolivia, Brazil, Costa Rica, Dominica, Trinidad and Tobago; Mongolia, Laos, Vietnam, Georgia, Burma, Philippines, Pakistan, Iran, Kyrgyzstan; Nigeria, Senegal, Madagascar, Congo, Ghana, Tanzania, Uganda, Liberia, Guinea-Bissau, etc.
Q2. Can you introduce your company?
A2: We have been engaged in high-frequency microwave equipment and terrestrial digital TV transmitter research, design, production, installation, debugging and maintenance for more than 14 years. EKE has a 3000 square meters factory area and a 15000 square meters CEKE Science park under construction, which are invested RMB90 million and will be put into usage in 2015. Welcome to visit it.
Q3. What are your Core Competence compared with other companies?
A3: (1) Wide Frequency Band Transmitting Solution (bandwidth up to 80-100MHz) ;
(2) M-SFN networking mode, we provide large-scale networking base on engineering construction experience;
(3) Simulation Coverage planning, we can simulate the signal coverage effect with longitude and latitude and tower height through our global geographic information;
(4) Design Platform & Wireless Terrestrial Digital TV System Integration, we provide one-stop service so that customers could buy the whole system and equipments.
Q4: Are there any installing training for customers?
A4: CEKE welcome customers sharing experience in our company, and we provide one week training for customers, including transmitter technology, engineering and maintaining regulations. We also can dispatch engineers overseas to install equipments, but customers should bear the cost of return-trip tickets, visa fees, accommodations, etc.
Q5: Should customers need to purchase backup devices?
A5: We highly recommend customers purchase backup devices, or at least buy backup modules. Because there are uncertain factors could cause damages when running equipments, such as lightning shock, unstable voltage, manual improper operation, etc. Therefore, backup devices protect the broadcasting from the interrupting.
Q6. If we cooperate with you, can we get enough guarantee and interest?
A6: We are committed to provide customers with the most competitive price, one year free warranty period(Non-artificial damage) and maintenance for lifetime to enhance our long-term cooperation. For mutual benefit, we spare no efforts in satisfying our customer in every possible way.

Q8: What is your producing period after we place an order?
A8: Normally, we will complete the production from 20 to 30 days after confirming the order, which influenced by the quantity complexity level of equipments.
Q9: Which instruments will be used when testing and inspecting equipments at the customer installation site?
A9: We recommend clients should test and record main technical parameters of signal source before transmitting signal source into transmitters. After transmitters operating smoothly, customers can test the signal whether meet expectation requirements in far range, middle distance and near area, which based on actual coverage requirements. In order to master the signal coverage situations, please select testing places as much as you can and these testing sites should be typical which cannot be obstructed. Required equipments should test signal input and output level, spectrum shoulder, MER and display signal frequency spectrum.
