International Open RAN Symposia (IORS)

The International Open RAN Symposia (IORS) provides a forum, via email lists, virtual meetings, and face-to-face meetings, for Open RAN experts to exchange information, work together on common goals, and create a community of practice for consistent, repeatable, international Open RAN testing.

Working Methods

IORS has a mailing list for online discussions and to distribute meeting announcements. This is an email reflector (i.e., anyone who is subscribed can send emails). 

• To subscribe yourself, send an email to: join-iors@osmmail.ntia.doc.gov 
• To unsubscribe, send an email to: unsubscribe-iors@osmmail.ntia.doc.gov 
• To email everyone who is subscribed to the IORS mailing list: iors@osmmail.ntia.doc.gov

If you want fewer emails, subscribe instead to the 5g-innovation mailing list by sending an email to join-5g-innovation@osmmail.ntia.doc.gov. Only ITS can send emails to the 5g-innovation mailing list. You will receive announcements about IORS meetings and other ITS 5G efforts.
