Player diversity
Reduce Time-to-Market
There is a wide recognition of Open RAN’s potential to disrupt the existing marketplace.At the same time, the low maturity of the technology presents challenges that need to be addressed.
RURadio Unit (RU) integratedinto Active Antennas
Open and virtualised RAN, Open vRAN, refers to a disaggregated approach of deploying virtualised mobile networks by using open and interoperable protocols and interfaces, implemented over a common propose hardware in a multi-vendor software environment, allowing an increased flexibility over traditional RAN architectures.,aiming to provide OPEX and CAPEX savingswhile fostering innovation.
