TE Connectivity sees CPRI interface gains traction with mobile operators cutting costs
CDIU establishes a direct digital connection between Alcatel-Lucent base stations and the TE DAS host unit, eliminating remote radio heads, radio-frequency (RF) conversions, and racks of attenuation panels in a DAS head-end. Typically, deploying a direct digital base station-to-host connection with CDIU reduces physical equipment by more than 50 percent and cost of materials by 40 percent, plus it reduces energy costs by as much as $100,000 per year in large venues.
CDIU has been deployed in several venues including:
- The Grand Hyatt Hotel in New York, N.Y.,
- Mizzou Arena at the University of Missouri in Columbia, Mo.,
- Paul Brown Stadium in Cincinnati, Ohio,
- Washington State University’s Martin Stadium in Pullman, Wash.
At these venues, CDIU has been deployed with the company’s FlexWave digital DAS platform using both high-power and low-power remote units. FlexWave DAS host units can drive both high- and low-power remote antennas from the same host unit, giving mobile operators and neutral host operators the flexibility to architect DAS uniquely and use CDIU at any site.
In addition to significant savings in capital and operating costs, CDIU delivers simplified installation and shorter deployment times. Rather than spending days cabling and installing racks of attenuators, the CDIU-to-DAS connection is a plug-and-play operation that takes minutes.
Finally, CDIU improves performance, testing and commissioning of a DAS. Rather than undertake expensive passive intermodulation (PIM) testing on cables linking antennas and amplifiers, operators can use the CDIU to generate a carrier waveform tone that makes it easy to optimize and troubleshoot the system.
