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.

Comments Off on Variable Power Management for LTE

LTE 4G variable attenuator

When it comes to precise control of power levels, DragonTECH has the best LTE solutions.

Systems like optical RF transport systems require flexibility for the site enginer to be able to finetune power levels, and yet high precision is required. Not to mention that it needs to be very reliable so the power levels stay exactly the same after testing and commissioning.

Consider the Variable Attenuator LTE 0-3000MHz, contact us for more details.

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.

New – Reflector Antenna

November 27th, 2009
Comments Off on New – Reflector Antenna

This refflector antenna is a special antenna designed for very high gain requirements, following are some examples.Reflector Antenna

Corridor

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.

Service sector restrictions

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.

Network Selective Donor Antenna

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.
