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.

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.
