Anyone working on O-RAN
Curious to see if anyone working on O-RAN or vRAN... The Telco industry seems to be at the crossroads trying to decide if this is the future for Radio access. @at&t @msft @verizon

U.S tier-1s will be slow in adoption since it is difficult to completely replace the traditional vendors who also handle the installation and deployment. With O-RAN there will be disaggregation of components coming in from different vendors and so, this needs to be completely validated in terms of interworking. This is an area for system integrators to step in and stand up to ease the deployment. Rakuten is an early adopter, JIO is doing it in India, Telefonica making some early moves and closer to home - DISH have plans to embrace it. So, in my opinion we are atleast some years away in US
T-Mobile US CTO has openly expressed to be against O-RAN.
What Verizon said. Also, some telcos are using O-RAN simply for negotiating leverage. They know it's a difficult-to-impossible to actually deploy, but they pretend to support it so as to threaten traditional vendors to cut their pricing. Sounds ridiculous, but sometimes works.
Vendors like Parallel Wireless are leaders in ORAN
I think PW has done great job with virtualizing RAN, but to me it seems to be lacking O-RAN compliancy; of course I don't know for sure, but this is just my observation and I might be wrong. There's two big O-RAN projects on-going; Rakuten in Japan and Dish in US. Why PW is not part of either of these ?
Yeap it's a turning point for Telco RAN, if things work well based on R&D dev. next coming years...if not O-RAN, atleast some form of vRAN using vnf/cnf . Interestingly, vendors like Nokia are all in, on this direction.
Let's not mix up vRAN and O-RAN. vRAN can exist or it is already existing without O-RAN. For example; Nokia has already virtualized RAN for 3G, 4G as well as for 5G. Also, O-RAN doesn't require vRAN. It's about open interfaces within RAN; in 5G that is F1 and eCPRI (Fronthaul). However, I wouldn't expect to see bare metal implementations of O-RAN.
Sometimes vendors publicly say they support something, while in fact they are posturing and don't have any intention of supporting it now or at any future time. Not saying that's the case here, but also not saying it isn't the case.
Interesting question indeed. I've been with Nokia very long time and worked with RAN since days of GSM. I'm sure O-RAN is eventually coming, but will it's prime be next or year after, I doubt about it. I've followed O-RAN specification development closely even it is not really my job, but because it is interesting. I'm sure new ORAN vendors who are with Dish are facing huge challenges in their integration activities to get RRH+DU+CU working. What I know, they haven't even managed to make first E2E call yet. It would actually be interesting to see to Nokia or Ericsson to provide let's say RRH and then see, if it worked right away with different DU and CU vendors without major integration and troubleshooting. Back to original posting; I don't think Telco RAN is in the cross road yet. Look at commercial deal numbers of both Nokia and Ericsson has; both of them has 100+. I would say O-RAN is something that Greenfield service providers may consider. Let's follow up how Dish is able fulfill the deployment requirements with their current O-RAN vendors.
Recent article about ORAN and TIP (FB's telecomInfraProject). Few words from T-Mobile US CTO as well: https://www.sdxcentral.com/articles/news/tip-pitches-bigger-open-ran-tent/2020/10/
Nvidia is the latest entrant to the market !! They have interesting roadmap for vRAN and it’s integration towards O RAN
If I remember right NVidia is working with Ericsson to use GPU as accelerator HW in vDU. Nvidia GPUs are considered as COTS (commercial off-the-shelf) HW.

What do you mean by "O-RAN"? A product that conforms to O-RAN alliance specs?
O-RAN == OpenRAN ~ as you said which conforms those specs you mentioned.
I'd dare to say that even conformance to ORAN specs doesn't make the RAN "open" ;)

VMware is partnering with Intel to create a software platform for vRAN: https://www.fiercewireless.com/tech/intel-vmware-collaborate-vran
Intel has their FlexRAN reference platform for O-RAN and VMware has actually already established position with some telecom companies as cloud platform provider. They are also working with Dish; see the press release: https://www.vmware.com/company/news/releases/vmw-newsfeed.DISH-Selects-VMware-to-Help-Build-the-Most-Advanced-Automated-End-to-End-5G-Network-in-the-U.S.459a7317-5c39-48ec-a2c1-fef8509d4075.html
