TE Connectivity Improves its FlexWave Prism DAS

We have all experience reception problems in certain types of environments when we are on a mobile device. Depending where you are and what you are trying to do with your mobile device, it can be a minor inconvenience or a very costly one. To overcome this limitation operators use distributed antenna system (DAS) to compensate for the lack of reception. TE Connectivity, designer and manufacturer of connectivity products, announced the introduction of new high-density modules for its FlexWave Prism DAS.

With the new addition, the FlexWave Prism platform will be able to support up to 75 MHz per band with two frequency bands per module. What this means for operators is they can now have a 2-bay FlexWave Prism remote unit capable of supporting up to four frequency bands, 40 watts, or up to 300 MHz of spectrum.

Services providers in the Asia-Pacific and Europe, Middle East and Africa (EMEA), can use this platform for 1800 MHz, 2100 MHz, or 2600 MHz MIMO and 800 MHz digital dividend services.

By supporting many different frequencies with high power output, future migration from 3G to 4G will be a seamless transition. Operators can also use this platform to shift capacity when the load in one area exceeds its limits. With a reach of 20 kilometers or 12.4 miles, it can be applied in multiple environments including urban and suburban areas, buildings, stadiums, office parks and other facilities.

FlexWave Prism uses a patented digital-over-fiber technology to distribute RF by digitizing the entire RF band and/or multiplexes direct digital CPRI or OBSAI feeds over dark fiber or millimeter wave links and reconstructs the signal at full bandwidth, regardless of modulation technology or BTS vendor, at the remote location.

Some of the features and benefits of this platform include:

  • A flexible architecture  that is scalable, modular and field upgradeable
  • Support for multiple frequency bands and wireless protocols in one enclosure
  • Air Interface and BTS vendor independent
  • Multiple non-contiguous segments of 1.5 to 75 MHz each
  • Embedded element management system, supporting web based access and SNMP
  • Fully sealed, maintenance free electronics for harsh outdoor applications

"The FlexWave Prism DAS supports multi-operator, multi-protocol services in a compact, cost-effective, and power-efficient manner. It is ideal for mobile operators who want to deploy DAS with multiple frequencies and high power levels without the complexity of multiple DAS equipment overlays," said Peter Wraight, vice president, TE Wireless.
