Radisys Series — Who Disaggregated My RAN?
eBook
Because the specifications are focused on interoperability, operators are able to look for solutions that meet their
needs, while vendors are able to develop and innovate products within their area of expertise.
Over the last couple of years, there has been good progress and greater alignment with Open RAN initiatives across
the industry, resulting in many operators signaling their intent to deploy Open RAN solutions. There have been 4G
Open RAN deployments already in a few countries, and many operators are issuing RFPs with O-RAN compliance as
a requirement for their 5G networks. Radisys has engaged with a number of operators to test disaggregated RAN
solutions in the lab and then seen those projects move from proof-of-concept to field trials.
The New RAN Vendor Ecosystem
The emerging trend of new architectures and interfaces enabling disaggregated RAN solutions along with COTS
hardware options, all aligned around standards and specifications, is fundamentally changing the RAN vendor
ecosystem. Operators are no longer locked into inflexible one-size-fits-most solutions. Instead, there is now space
for newer players specializing in hardware and software components that deliver high performance, flexibility and
increased visibility into RAN nodes and spectrum efficiency at optimized price points.
So what does that market look like? We will cover that in our next post. Stay tuned!
