Interference to your 3G and 4G services?

Comments Off on Interference to your 3G and 4G services?


newBetter Data with our New Bandstop Filter

With more and more of our clients having problems with LTE and 3G interference from different RF sources, this new filter helps prevent any interference from the frequency band 1983.1 – 1990 MHz.

Interference Prevention with Customisation

We can customise any Passband and Stopband for your case with 30 to 50 dB rejection suiting your needs. Normally 30dB rejection is adequate in most cases, meaning that the interference is supressed to at least 20 times lower in power. This will improve voice and data significantly, bring more traffic, more revenue and happier customers in the network with improved LOYALTY!

Integrated Point of Interface for LTE 2×2 MIMO Systems

June 7th, 2013
Comments Off on Integrated Point of Interface for LTE 2×2 MIMO Systems

This POI integrates all the necessaary circuitries into a neat 19″ rack mounted chassis. This connects 2600MHz LTE network operator with 2 x 2 MIMO ports to your In Building Antenna System.

Advantage of Integrated POI

  1. Integrated design eliminates human error in jumper connection
  2. Compact design reduces space requirement by 50%+ in the precious equipment room
  3. Test port making it easy for T&C
  4. 20dB power adjustment provides flexibility in the link budget
  5. Special heat dissipation management allow the system to operate without fans to eliminate maitenance needs

Advanced Technical Design Enabling the Best Data Throughput

  • Duplex input per operator. This is customisable if needed.
  • The RF will then be routed through the duplexers, attenuators, splitters & combiners as necessary and eventually give 2 pair of MIMO UL DL ports to be connected to the Hub or host units as needed.
  • Power control at 20dB range so there is flexibility on-the-fly or post installation. These will be set by screws on the front panel of the 19″ standard rack mount chassis.
  • Test port for trouble shooting and T & C.
  • All components are contained within the chassis to avoid any chance of tempering by known parties after T & C.

Other types of systems supported:

  1. WCDMA / 3G
  2. GSM
  3. CDMA
  4. Tetra
  5. DCS

We will customise the POI to suit the unique requirements from each project. Below is an example of a POI system connecting various GSM operators to 10 Hosts of the DAS system.

Invisible LTE Antenna for ALL frequencies

December 29th, 2011
Comments Off on Invisible LTE Antenna for ALL frequencies

Our Invisible Antenna  has recently been upgraded to cover all 4G/LTE frequencies, making it a truly global choice for all LTE systems.

Invisible LTE Antenna (datasheet)

Why is it Invisible ?

Our invisible antenna is one of our best selling items. This is mounted from above the false ceiling and only the ‘smoke detector’ shape is seen by the users. Making the antenna invisible

How does it help Data service for 3G / 4G?

This actually allows you to have the dipole below the ceiling for maximum Data performance, while it is so low profile that does not make users think that there is an antenna. Since the dipole is below ceiling, it will not be blocked by builder materials. These materials are often made of metal which reduces available radio signal strength and caused reflection and difraction. By using the Invisible Antenna, the maximum Signal to Noise Ratio and Signal Strength are acieved to allow best  Voice Quality and Data Throughput.

Why is the Invisible Antenna best for 3G / 4G?

We have now upgraded this Invisible Antenna to support 700 MHz to 6000 MHz, covering the 4G / LTE frequencies. By using this antenna, the building is future proof. If an upgrade is required you are ensured that the antenna can continue be used to support the next technology.

4G (Long Term Evolution LTE) Ready Antenna / RF Components

January 30th, 2010
Comments Off on 4G (Long Term Evolution LTE) Ready Antenna / RF Components

DragonTECH is

4G

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.

New Frequency Bands for 4G

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):

LTE Frequency

Is my DAS really ‘Future-proof’ for 4G?

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.

Challenges for RAN (Radio Access Network)

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.

DragonTECH has a solution

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.
