Guilin CEKE Communication Equipment Co.,Ltd, located in the picturesque Guilin High-tech District Information Industrial Park, is a private joint-stock enterprises with more than 10-year experiences in MMDS,UHF/VHF wide band frequency equipment and terrestrial digital TV transmission system research, design, production, installation, debugging and maintenance. CEKE has a number of senior MMDS UHF/VHF wide band frequency technology and terrestrial digital TV technology R&D experts; first-class instrumentation equipment; 3000 sq meters production and maintenance facilities, it is a very strong manufacturer of MMDS UHF/VHF wide band frequency equipment.
CEKE has the long-term good R&D cooperation relationship with the China North Industries Group 206 Institute, Guilin Institute of Automation Technology, Beijing University of Posts and Telecommunication, Guilin College of Aerospace Technology. With maintenance capability of most of the global communication MMDS UHF/VHF wide band frequency equipment, mobile base station, repeater and wireless bridge, CEKE now undertake the imported mobile communication equipment maintenance business for more than half of all the China's provinces. With the capability of the research, design, production, installation, system integration, network planning of digital microwave transmission equipment, digital-analog compatible MMDS transmitter, terrestrial digital TV transmission system equipment, CEKE is an industrial leader especially in product and service quality.
Aiming at the existing problems in DTMB terrestrial digital TV network construction, CEKE carried out a technical research, successfully launched the first terrestrial digital TV broadband transmission system in June, 2008. Now, the same kind of wide band frequency system projects have been opened up and operating more than 40 stations, 5 multi-channel single-frequency network system, with its mature technology, stable system, and significant performance, CEKE's solution has become the best wide band frequency transmitting network construction solution.
Wide Band Frequency Transmitting Technique Profile
Wide Band Frequency Transmitting System
Wide band frequency transmitter is the latest breakthrough based on transmitter manufacturing technology, the technology is based on undertaking a series technology of single channel transmitters, by improved and optimize the technical index like equipment noise figure, the phase noise, frequency accuracy, the shoulder, etc. So as to meet the need of wide frequency band transmission (equal or more than 100 MHz). This solves the technical problem that can not realize adjacent channel transmission because of the technical limit of high-power combiner, not only save the cost of transmitting power, but also improve the utilization rate of frequency. Meanwhile it is convenient for the construction of M-SFN network.
The advantage of wide band frequency transmitting system
System brief and low cost.
One transmitter can transmit 12 within the radio and television adjacent frequently channel, system cost is reduced by more than 50%.
Low noise and high efficiency.
The noise figure of the low noise design transmitter is less more than 9dB compared with single channel transmitter, meanwhile no need of multiplexer, the total insertion loss reduce 2-3dB, it makes the effective power transmitted from the antenna terminal improve multiply.
Low power and low power consumption.
One wide band frequency transmitter can replace multiple single-channel transmitter, and the system power decreases by N times, power consumption saving N times (N=channel number)
Adapt to frequency bandwidth, easy and convenient for frequency adjustment.
The last stage power amplifier of the wide frequency band transmission system adapt to frequency bandwidth(equal or more than 120MHz), the user can adjust and change the transmitting frequency at any time when need to adjust and optimize the network.
Our Capacity
Emulational Software of Terrestrial Digital TV Coverage Planning
Our company uses the latest simulate coverage calculation software, it can calculate the transmitting station’s coverage effect by factors such as terrain, landform, reception antenna height, earth curvature, etc. Meanwhile, simulative activeshade process and formed visual coverage effect diagram, it can show anyone transmitting station coverage effect, offer scientific basis for networking plan.
