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.

64 Network Operators Have Committed to LTE in 31 Countries

China Telecom, China Mobile and its subsidary CM Peoples have announced their committment to LTE. This will mean that LTE will be the de facto standard for wireless high speed data in the region. LTE is the natural migration choice for GSM/HSPA operators and is the main direction for the industry. LTE is also the next generation mobile broadband system of choice of leading CDMA operators.

DragonTECH is LTE Ready. We have a fully developed range of products and solutions.

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

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.
