OCUDU 26.10's release notes flag Split 7.2b and two positioning features as untested

The 26.10 release notes put a test status beside individual features, and I think that habit is the best engineering in the release. Split 7.2b support is described as a baseline and "not yet tested with O-RU" ^[9]. The beam-management baseline is waiting on the same O-RU test ^[9]. Two positioning features, angle-based positioning and generation of the downlink positioning reference signal, still lack an end-to-end test ^[10]. The other new items include two-step random access, uplink pre-scheduling, configured grants and DTLS signaling encryption ^[8].

The 7.2b flag lands on the project's stated purpose. OCUDU's technical project describes a permissively licensed CU/DU with the full L1/L2/L3 stack, aligned with 3GPP and O-RAN specifications ^[17]. The foundation wants vendors and research groups on one codebase, and expects shared testing to make open RAN components easier to integrate across suppliers ^[20]. Split 7.2b sits between the DU and the radio unit, where two suppliers' equipment would meet.

The release notes also say VALOR Labs validated OCUDU against O-RAN end-to-end and security test specifications ^[11]. Quoted alone, that line overstates the test record. According to RuntimeWire, the project-reported validation does not cover the hardware and end-to-end limits flagged on particular features ^[12].

The release notes do not establish a satellite deployment or production use by an operator, and the Linux Foundation's announcement does not name a deployment or compare performance, RuntimeWire reported ^[13]. For once there is no benchmark table to discount. In my view, 26.10 is a sound base for lab work on Release 17 NTN ^[2] and on the new positioning code ^[10].

The engineering lineage runs through Software Radio Systems ^[4]. Ismael Gomez, its co-founder and CTO, chairs the OCUDU Technical Steering Committee ^[4]. The Linux Foundation said in March that the National Spectrum Consortium and the FutureG Office funded DeepSig and SRS to build OCUDU's initial software ^[6].

Arpit Joshipura also said active contributors to the technical project have doubled and participating organizations have grown tenfold ^[15]. A Linux Foundation update in May counted 21 new member organizations since launch ^[16]. If that count and the October figure of 95 are both cumulative, 74 organizations joined between the two announcements ^[21]. Members include telecom operators, equipment and silicon vendors, cloud providers and research institutions ^[18]. RuntimeWire noted that membership alone does not establish a paid deployment or a commitment to use the software ^[19].
