From 1b8a6d001bcb67341093c8fc9b4f0a6a786efe18 Mon Sep 17 00:00:00 2001 From: Reem Bahsoun Date: Tue, 25 Mar 2025 15:29:42 +0100 Subject: [PATCH] Add documentation for Foxconn RU in ORAN_FHI7.2_Tutorial.md - This addition is based on past tests, iperf3 UDP throughput was 520Mbps DL and 40Mbps UL. - Throughput degrades when using OAI L1 with tags beyond `2024.w30`. - This RU is being CI tested only in the Aerial pipeline, not with OAI L1. - The document will be updated once the issue is identified and fixed. --- doc/ORAN_FHI7.2_Tutorial.md | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) diff --git a/doc/ORAN_FHI7.2_Tutorial.md b/doc/ORAN_FHI7.2_Tutorial.md index c28f75a2cf..560733881f 100644 --- a/doc/ORAN_FHI7.2_Tutorial.md +++ b/doc/ORAN_FHI7.2_Tutorial.md @@ -72,6 +72,7 @@ tested any RU without S-plane.
