An antenna diplexer or RF diplexer is a unit or module that enables two antenna feeds to be combined and carried down one feeder. Conversely, it can act as a splitter to enable the signal from one feeder to be connected to two receivers or antennas.

Tetra 400 / Mobile Diplexer

Diplexer 400 Tetra / Mobile

• Tetra and mobile antenna diplexer enables Tetra security and Mobile Cellular radio signals to be combined or split with a single feeder.
• Enabling multiple transmitters to use a single antenna: Mobile services often use multiple frequencies, possibly for different Mobile Network Operators. In view of the size and cost of the antennas they may have a single antenna and they may want to combine the signals from several transmitters to feed into the antenna. As they are on different frequencies, it is possible to use a diplexer to combine the signals and use a single feed.
• Enabling a multiband transmitter to use different antennas according to frequency.
• Allowing single feeder to be used for multiple feeds. The signals from he antennas can be combined at the antenna end using diplexer, and a second diplexer at the point of use to route the signals.

We have a TETRA system from Motorola which we would like to sell.

These are used by police and security forces worldwide. Some proerty management groups will use them too. These are like walkie talkie radio but they are digital and they have data communications capability.

The system we are selling has 3 cell sites and 200 subscribers. Condition is excellent.

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):

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.

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.
