Collision Communications is launching its new C-RAN Receiver Solution that uses advanced signal processing to achieve 500% performance gain in dense network environments ahead of 5G

Advanced signal processing pioneer Collision Communications is launching its C-RAN Receiver Solution, designed to dramatically improve spectral efficiency in LTE and 5G network environments through new approaches to interference suppression. The software solution uses innovative techniques developed by Collision to turn signal interference into significant gains in network performance and utilization of costly spectral assets.

Faced with ever-increasing cost pressures, it’s important for mobile network operators to make the most of spectrum investments. But, as the demand for consumer and enterprise data continues to grow, carriers have to deploy increasingly dense networks, which, in turn, compound complicated interference issues. To push costly networks closer to what is theoretically possible (Shannon’s capacity), and provide the quality of experience needed to combat churn, operators need solutions that more effectively address interference.

Jared Fry, Collision Communications chief operating officer, discussed the company’s unique take on interference in a conversation with RCR Wireless News. “With the ability to understand and interpret the interfering signals, mobile networks can allow interference to exist while enabling significant gains in spectral efficiency. Through many years of R&D, Collision has designed and implemented approaches that flip the interference paradigm. We’ve actually developed sophisticated methods that harness interference to improve network performance.”

Collision’s new C-RAN software simultaneously processes interfering signals from a large number of distributed antennas. Consider a seven-site C-RAN cluster: Collision demonstrates spectral efficiency of more than 10 bps/Hz per 4-antenna site achieving more than 700 Mbps in just 10 megahertz of bandwidth on the Uplink.

Key features of the C-RAN Receiver Solution include:

  • Ability to jointly process up to 28 antenna signals, or operate in a PHY-distributed configuration.
  • No additional hardware, and is designed to run within OEMs’ baseband processing platforms.
  • Reduced sensitivity to antenna placement and aim, resulting in eased network planning and deployment efforts.
  • Provides for much more consistent user performances, and effectively eliminates performance degradation at the cell edge.

“Fundamentally, we are offering a better performing solution that can improve OEM products by improving spectral efficiency, particularly in challenging interference environments,” Fry said. “Given the market outlook in terms of amount and type of data demands, networks are only going to become more dense making interference, and its performance-degrading effects, more challenging. Our technology fills an important need in the telecom ecosystem as carriers and their vendors work to make the most of the spectrum they have.”

Collision is currently demonstrating its C-RAN solution on an industry-common SoC platform with key industry players. To learn more about Collision Communications, please visit: http://www.collisioncomms.com or contact Collision through [email protected].
