Mavenir and Sunwave announced Tuesday integration of Mavenir’s virtual RAN architecture with an Open digital interface into Sunwave’s CrossFire product portfolio and that first customer trials are now underway.
The companies will jointly or independently support OpenRAN deployments in the enterprise private LTE market and take end to end responsibility.
Existing Distributed Antenna System (DAS) deployments using the CrossFire platform can now be upgraded to support OpenRAN architectures and have an immediate path to 5G. The combination of Mavenir’s OpenRAN and enterprise communication portfolio together with Sunwave’s enterprise portfolio, provide the industry with a true OpenRAN production-proven platform supporting 4G/5G for enterprise and private LTE.
The evolved RAN architecture, designed with cloud-native virtualization techniques, enables the RAN to flex and adapt based on usage and coverage. This flexibility provides expanded and more convenient network location choices for the baseband processing.
Therefore, this architecture naturally fits in existing networks’ backhaul infrastructure and is future-proof for evolution towards a fully virtualized and cloud RAN architecture. In addition, it offers a strategic differentiation by enabling the Remote Radio Units (RRUs) to interwork with the Virtualized Baseband Unit (vBBU) over a non-ideal fronthaul (i.e. ethernet), overcoming the traditional constraints of CPRI over fiber.
Conventional RAN platforms have been based on proprietary hardware and rely on long life-cycles in development, deployment, and operation. With each generation of radio interface change, these radios are typically replaced with the newer versions at a significant investment and inconvenience to the CSPs.
Furthermore, radio infrastructures based on this approach are designed based on the peak capacity without granular power and interference management capabilities. This creates the vendor lock-in and the inability to keep pace with technology and demographic transitions.
