Moreover, the proprietary nature of the equipment and interfaces that connect the hardware locks MNOs into existing relationships with the vendor that originally supplied them. Bettersnaptool network access upgrade#Making any upgrade or change to the wireless network, even seemingly minor ones, requires replacing physical hardware throughout the network-a costly, manual, and time-consuming process. While these traditional systems have worked well for MNOs, they have many drawbacks. The RAN uses proprietary hardware and vendor-defined communication interfaces, and its software-driven functionality is tightly integrated inside the hardware. Why open RAN?Īt its most basic level, the RAN architecture at the mobile network edge comprises a remote radio unit (RRU or RU) at the top of a cell tower that communicates with a baseband unit (BBU) located at the tower’s bottom. 4 Moreover, if governments force MNOs to replace installed 5G RAN equipment from restricted vendors, the growth rate may be even higher. If this trend continues, the open RAN market has the potential to grow substantially, with some estimating double-digit growth rates 2 that will push open RAN to approach 10% of the total RAN market by 2025 3 from less than 1% today. Economic and competitive forces are also converging to drive the market forward. While it may take anywhere from three to five years for the technology to fully mature, open RAN adoption should accelerate rapidly thanks to the logic of its network design and its strategic alignment with carrier needs. Although deployments are starting slowly, they could easily double in 2021. We estimate that there are currently 35 active open RAN deployments across the globe, 1 many of which involve MNOs testing open RAN in greenfield, rural, and emerging markets. The open RAN market is still in its early days. And because MNOs must replace or augment existing RAN equipment to deliver 5G service, they have the opportunity to adopt open and virtualized RAN architectures-which we will refer to simply as “open RAN”-as part of these deployments. They now have their sights on their distributed mobile edge networks: the radio access network (RAN). Many MNOs are well on the journey toward opening and virtualizing their core networks, achieving significant operational gains.
