Our client, one of the leading European telecom operators, wanted a working solution of Arttha5G O-RAN Radio Unit (RU) running on a reference hardware (H/W) platform called Bonnyrigg, supporting both Sub-6GHz (FR1) and mmWave (FR2), FrontHaul and RF FE (front end).
They needed a solution for low-to mid-band frequency range (FR1) that is compatible with both analog front-end (AFE) and radio frequency (RF) solutions. The client also wanted us to conduct thorough end-to-end testing involving DU-Simulator connected over eCPRI through fibre and Bonnyrigg supporting FrontHaul, LowPhy+DFE and RF FE.
We reached out to the client’s team and gathered all the requirements for a 5G solution in detail. We understood their problem and created a customized strategy to help the client efficiently implement a high-frequency Arttha5G O-RAN RU running on reference H/W platform.
After understanding the client’s requirement, our Arttha5G team seamlessly implemented Arttha5G O-RAN RU solution on their reference hardware platform. We met the performance specs requirements as per the 3GPP specification. The digital front end downlink chain was operated at digital-to-analog converter rate of 491.52 MSPS.
As per the client’s requirements, we also conducted the end-to-end testing using Matlab based 5G NR RU Frequency domain test vectors (for frequency division duplex (FDD) mode mu1_100MHz) and decoding analysis on vector signal analysis (VSA) equipment for the constellation, EVM, PSD etc.
With our Arttha5G RU solution, the client was able to achieve:
Better throughput for wide area coverage
Interoperability among connected devices
Ultra-reliable low latency for faster communication
