Sounds Long Term, LTE is really round the corner, there are already existing comemrcial networks launched and surely there will be more with new markets for high speed data driving multi-media applications like You Tube and Facebook. Let’s take a look at the challenges posted to antenna systems.
LTE supports flexible carrier bandwidths from 1.4MHz up to 20MHz, in many spectrum bands and for both FDD and TDD.
This means an operator can introduce LTE in both new and existing bands, for example, 2.6GHz (Band 7), Advanced Wireless Service (AWS) (Band 4), or 700MHz bands.
Unlike other earlier cellular systems, LTE will be quickly deployed on multiple bands. Click here to see Verizon’s Band.
Todate, this is a broad summary (click to enlarge):
This post a challenge to the existing Distributred Antenna systems (DAS) which ‘flexibly’ supports 800 – 2500 MHz. This was good enough at the 2G times, so that DAS deployed back then are ‘future-proof’ for 3G systems.
It worked well until now.
4G will now definitely spread from 700 to 2700 MHz, rendering the existing DAS system vulnerable should the local regulator mandates the use of 700 or 2600MHz.
For the Network Operators, your mobile subscribers are adopting 3G services but the traditional 2G subscriber base keeps growing too. You face the need to expand both network layers for more capacity and coverage to improve both the quality of service and availability. And with the onset of LTE, you must further develop your networks and rationalize your investments to deliver profitable services.
All these calls for a Converged RAN that can support from 700MHz to 2700MHz.
As an industry leader, DragonTECH has developed a series of RF components and antenna to resolve this issue. These can be used for any DAS build for 2G / 3G now and the customer is ensured a smooth upgrade path to 4G in the very near future.
This refflector antenna is a special antenna designed for very high gain requirements, following are some examples.
If you need to cover 2 corridors at 90 degrees, adjust the reflector so that all RF is radiated within this 90 degrees to maximise performance and you only need 1 antenna instead of 2 panel antenna.
If you need to radiate highly directionally to a specific area; and do not want signal over spilt to outside this area, this antenna is for you. It can restrict RF to 40 degrees.
If you have a repeater site with multiple networks, and that you do not want to pick up signal from competitors and re-transmit them inside the building, you can use this antenna to sharply point to the preferred BTS and use the reflector to selectively block other network out by the attenuation from the reflectors.
Thanks for your support. Our Service Geographics has been ever expanding. We just updated our service coverage map. I would like to post it here to tell you how much DragonTECH appreciated your friendship and support.
We will give you Spliiters with Jumper Cables Affixed!We have a new series of Power Dividers that comes with the necessary Jumper Cables. The length and connectors can be customised.
This alleviates a lot of connections on site for a faster and easier implementation. In cases where clients are charged according to the BoQ this new idea greatly reduceds install cost.
We can customise Jumper Cables and RF components for you.

DragonTECH Tower Mounted Booster together with micro base station gives macro base station coverage with minimised investments. The result is lower infrastructure cost per square kilometre.
DragonTECH strives to be more easily accessible to the market. We participate the recent exhibition in Shenzhen, featuring the top vendors in the optical field.
The China International Optoelectronic Exposition (CIOE) is a worldwide renowned exhibition, which presents the most advanced optoelectronic technologies and innovations. The CIOE 2009 expects around 2,100 exhibitors to showcase products on 70,000 sqm from September 6-9. During the four days, more than 85,000 professional visitors will attend the exhibition. It is supported by all relevant Chinese government bodies, scientific academies, trade associations, and by domestic as well as international key players of the industry。

We have got such a wide range of products for RF systems parts and components. It is always a challenging job to keep our product pages update, readable, tidy and easy to use.
But as you see we always try.
The pruduct page has now been added with:

Recently a lot of customers asked for QMA connectors and jumper cables.
ting TimeQMA or Quick Lock SMA connectors enable fast and easy matings. It is a good alternative to SMA dna N type connectors. It uses a Snap-on mechanism to allow matings to be fast and secure. It is secure through a chamfer with a click sound during a positive mating.
The DragonTECH QMA connectors are tested against shock and multiple matings. Below is the straight type.
QMA connectors have a lower space requirement because the use of a wrench is not needed here. In addition, the small size and the distance between connectors can be optimised on the equipment panel.
Below is the DragonTECH QMA Righ-angled connector.
We will supply Jumper Cable Assembly with RG223 cable.
We introduced our Smart Elevator Solution a few days ago.
Readers customers keep flooding emails in asking for dual band and triband versions. To save more people writing, here it is:
Dual band and Triband SES
This unit maintains performance with improved appearance.
It is compact and uses external donor and service antenna.
As before, customers can speify the bands and we will customise them.
