The VRM-mini-SDR is a miniature, software defined base station platform that supports ready-to-deploy LTE and 2G/3G solutions, and is also an exceptional development platform for custom waveforms. The VRM-mini-SDR is a perfect fit for applications requiring the smallest possible size, very low power consumption, and exceptional frequency agility. OEMs can use the platform to implement complete systems including portable small cell base stations, network analyzers, and specialized embedded radio systems.

The VRM-mini-SDR platform incorporates flexiPHY GSM, UMTS/ HSPA, CDMA2000, and LTE -FDD/TDD software, and is pre-integrated with a range of commercial Layer 2/3 stacks from leading vendors, saving months of development work. OEMs can leverage the complete solution to deliver high-performance base stations offering their own differentiating features, while reducing development time, cost, and risk. OEMs also have the option to integrate their own Layer 2/3 protocol stack, or to implement fully custom waveforms using the Opus Studio development environment.
