Overview
CPRI (Common Public Radio Interface) is an interfacing standard for high-speed communication of digital radio samples and control data between wireless infrastructure base station inter-modules. MTI’s IPC-CPRI-v.4.2 solution enables the quickest and most reliable deployment of REC (Radio Equipment Controller) interfaces for easy and flexible interfacing to Remote Equipment. It includes all features required to support LTE/WCDMA/WiMAX standards. MTI’s IPC-CPRI-v.4.2 is a self-contained and fully tested solution compliant with the latest CPRI v.4.2 specification and the market leading solution used today in many eNb field installations as well as in Tier1 DSP ASICs and FPGAs devices.

Powering Scale Up and Scale Out with 224G SerDes for UALink and Ultra Ethernet
At the recent ECOC 2025 conference in Copenhagen, Cadence showcased its key role in enabling the future of AI infrastructure with live silicon demonstrations of several essential IP technologies for emerging 800G and 1.6T networks. Powered by Cadence's 224G SerDes IP, Cadence's Ultra Accelerator Link (UALink 1.0) scale-up and Ultra Ethernet scale-out networking solutions deliver the performance, flexibility, and interoperability needed for next-generation AI factories and hyperscale data centers.
O-RAN Fronthaul Security using MACsec
With 5G being deployed for time-sensitive applications, security is becoming an important consideration. At the same time, Open Radio Access Networks (RAN) are gaining more interest from mobile carriers and governments. Yet, Open RAN networks have serious security challenges, especially in the RAN fronthaul where there are strict timing requirements. This paper proposes MACsec as an efficient data link layer security solution that can assist in meeting these challenges.
Seize the Ethernet TSN Opportunity
The following sections will take a look at the major Ethernet performance issues and how the extensions address those shortcomings. This will be followed by an overview of the applications of TSN for 5G, industrial automation, automotive invehicle communications and avionics. The paper will conclude with a description of Ethernet TSN solutions offered by Comcores.
Part 2: Opening the 5G Radio Interface
Carriers are now deploying 5G across the globe driven by the need to keep up with relentless mobile data growth. 5G New Radio (NR) operates at higher frequencies to increase bandwidth, but at the expense of range. There will therefore be a need for a much larger number of 5G RUs to provide the same coverage. The availability of cost-effective, reliable and open 5G radio units is therefore critical.
