5G Open RAN

The Advent of 5G ushers in a new era of ultra-large scale connectivity to accommodate IoT, significant bandwidth increases to meet the exponential growth of social media, streaming and gaming services, and low latency support for delay sensitive applications such as autonomous vehicle control and commercial drone applications.

To satisfy all of the use cases, more sophisticated design architectures are deployed within the Radio Unit (RU) and Distribution Unit (DU) .This, in turn, results in the need to manage more components on control paths and attention to power and thermal requirements of the system is critical.

In addition, board security is an important consideration as carriers are increasingly scrutinizing the integrity of equipment to defend against malicious attacks designed to incapacitate the network.

Lattice FPGA solutions provide:

  • Highly scalable PLD solution to meet all control needs
  • Best-in-Class security solutions to ensure protection of all boot functions and devices
  • Programmable to accommodate evolving 5G standards in the control plane
