- Open and Virtualized RAN Solutions
Traditionally, network operators have relied on a single vendor for the entire Radio Access Network (RAN) implementation and optimization. This closed ecosystem presents a significant challenge: hardware-based appliances have short lifespans and require lengthy design cycles for upgrades, hindering revenue generation for operators.
Tejas’ Open Virtualized RAN Solution: Tejas’ truly open and ORAN-compliant Distributed Unit (DU) solution features an open software framework that provides a uniform model of the hardware underneath and simplifies the development of portable RAN software. The open fronthaul interface (eCPRI) and Control & Management Software comply with ORAN standards, enabling plug-and-play interoperability with third-party DUs.
The hardware platform and the software framework can work independently of each other and offer their own benefits. The main benefits of the combined hardware/software solutions are:
Flexibility: Implement Virtual Network Functions (VNF) on a merchant silicon and permit ‘change’ features in the software.
Scalability: Provision and group together compute elements dynamically to provide a high aggregate compute throughput to provide more elasticity to the hardware platform.
Portability: Ability to seamlessly ‘port’ DU software on different hardware platforms, with almost no changes to the DU software.
Interchange COTS and custom hardware solutions: Ability to accrue all benefits of a custom solution like lower TCO while retaining all the benefits of a COTS solution like containerization.
