- Optional monitor methods, RS232/SMS.
II.Product Description
Triple-band wireless repeater can amplify two bands or multiple
sub-bands signals at the same time by sharing one antenna feeder
system. It is a good solution for multi-operator coverage projects
because the infrastructure costs will be greatly reduced.
In the downlink path, the repeater will pick up the signal from the
exiting transmitter via the donor antenna, amplifying and
re-transmitting it into the desired coverage area via the service
antenna. In the uplink path, the repeater will receive signals from
cell phones in the covered area and re-transmit them back to the
base station.

Company Profile
ZD Telecom was newly established in Sep. 2009 by its founder who
had been working in one of the earliest companies in the
wireless/RF industry of China for more than 10 years of R&D and
management after graduation from the best in China of“ University
of Electronic Science & Technology of China”,with a back up of
a group of veteran engineers cherishing the value of
“professional(attitude) & excellent(products)”.
We are true manufacturer with a facilities of 2000㎡ and 150 heads
of working force, not any of trading or solution provider
companies, specializing in products of
coverage/enhancement/optimization for wireless network and
previously have been working as a role of OEM for some other big
names of telecom equipment suppliers. We now step forward to the up
front and devote to adheres to the business strategy of “customer
oriented and continuous improvement”, and closely keeping to the
principle of customer satisfaction, quality first, competitive
price, fast delivery and service in individual place.
On the basis of such, we will continuously, as at our starting
point, be striving to develop state-of-art products for the
wireless telecommunication and antenna as our long run direction
with our professional ability,rigorous attitude and standard of the
line and enthusiasm and constant input of money for R&D.
With combined endeavours of years in this line,ZD has developed its
own "RF passive products","Systemproducts"and the "The system
structure" "Antenna"product line. Taking the advantages of China’s
best supply chain of local industry as a plus, ZD is bracing up to
become an important participator in the feeder antenna and the
field of wireless network optimization equipment both in China and
the outside world.
