AT&T keeps RAN hardware options open beyond Intel

AT&T is pushing ahead with a more software-driven mobile network and wants to avoid locking itself into any one hardware vendor, including Intel. Network CTO Yigal Elbaz says the company is building its radio access network (RAN) so that software, not proprietary boxes, does most of the work. That approach is meant to let AT&T swap in different processors and radio gear over time, as long as they meet its technical requirements.

Elbaz also gave an update on AT&T’s open RAN plans, which aim to standardize interfaces between network components from different suppliers. The goal is to keep options open, increase competition among vendors and support ongoing wireless upgrades without constant large-scale hardware replacements.
