Whether it’s open RAN or not, it’s just an interface so that’s kind of immaterial,” he said, pointing to the industry’s widespread use of Linux for operating systems, for example. “Everyone is using some open source software. Quantifying the extent of open source in RAN is a bit nonsensical because it exists in copious lines of code, but its impact is another matter entirely, according to Papa. “No one wants to admit it right now, but that’s where I think it goes and that’s why I don’t think it’ll be an open source thing.” Copious Code, Immaterial Impact The same market dynamics are in play in WiFi radios with proprietary software tightly integrated with silicon, and that’s the trajectory that open RAN is on, Papa explained. “We still don’t have a successful open source core” and “that’s a hell of a lot easier to do in open source.” “You’re going to see an open source core that’s successful long before you’re seeing open source radio components that are successful,” Papa said. “It’s just that the radio software, as it turns out, is as much about your test and environment as it is the software itself, and that requires specialized equipment and whatnot that doesn’t lend itself well to an open source development community,” he said. While open source is commonplace in data centers that power hyperscalers and some of the behind-the-scenes technology in wireless networks, there isn’t much of it in radio software, explained Steve Papa, CEO and co-founder of Parallel Wireless. The scant presence of open source in RAN causes lament among some open RAN proponents too. The total contribution of open source through the first nine months of 2020 “would be at a maximum $600,000 against a market we estimate to be around $29.5 billion,” he added. The largest RAN vendors, which aren’t exactly champions of open source, including Huawei, Ericsson, Nokia, Samsung Networks, ZTE, Fujitsu, and NEC control about 99% of the RAN market, according to Schoolar. ![]() “Open RAN does not equal open source software.” That lack of influence carries over to the open RAN environment as well, he said. Open source software, or free software that a vendor could download to a baseband or radio unit, doesn’t contribute to a significant portion of the RAN market, according to Daryl Schoolar, practice leader at Omdia. I have followed all appropriate research reporting guidelines and uploaded the relevant EQUATOR Network research reporting checklist(s) and other pertinent material as supplementary files, if applicable.Despite the widely acknowledged allure and prevalence of open source technology, it’s making nary an impact in radio access networks (RAN). I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance). I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as. No IRB approval was required for this research.Īll necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived. The details of the IRB/oversight body that provided approval or exemption for the research described are given below: I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained. We did not recieve any funding for any aspect of the work presented in this submission. The authors have declared no competing interest. To demonstrate, we fit our model to three regions (Spain, Italy, NYC) where the peak has passed and obtain predictions for the Indian states of Delhi and Maharashtra where the peak is desperately awaited. We further present a novel method for estimating the uncertainty in our predictions based on first principles. We employ publicly available mobility data from Google to estimate social distancing covariates which influence how fast the disease spreads. Given the amount of uncertainty surrounding the disease we choose a simple SIRD model with minimal assumptions enabling us to make robust predictions. We examine various existing models and their shortcomings. As India emerges from the lockdown with ever higher COVID19 case counts and a mounting death toll, reliable projections of case numbers and deaths counts are critical in informing policy decisions. ![]()
