The OCTBTS 3500 is a dual-sector software defined base station platform that supports any combination of GSM, HSPA, or LTE sectors, or custom waveforms. The OCTBTS 3500 is a perfect fit for applications requiring small size, low power consumption, and exceptional frequency agility. OEMs can use the platform to implement complete systems including dual-mode outdoor small cell base stations and specialized embedded radio systems.

The OCTBTS 3500 platform incorporates Octasic’s flexiPHY GSM, HSPA, and LTE software, and is pre-integrated with a range of commercial Layer 2/3 stacks from leading vendors. 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 stack, or to implement fully custom waveforms using Octasic’s Opus Studio development environment.
