4G Scalable Baseband Unit (BBU)
A carrier-grade LTE Baseband Unit that offers scalable baseband processing for multi-sector macro basestations. The Signaltron 4G BBU pairs with remote radio heads (RRHs) over high-speed CPRI to deliver wide-area coverage and capacity with a single system. Designed to scale from 3 sector sites to large 6 sector x 4 band, high-density sites—without re-architecting your network. One BBU system for up to 24 sectors, improving utilization and simplifying upgrades.
Standards-compliant 4G/LTE with VoLTE, video calling and broadband data. The BBU connects to EPC and IMS over secure IP backhaul. Ideal for both operators networks and large private networks.
Why Signaltron BBU?
Perfect for macro coverage, capacity expansions and rural clusters with distributed RRHs.
- Flexible duplexing: Supports both FDD and TDD to match spectrum strategy.
- RRH/RU support: CPRI/eCPRI interface.
- High-capacity fronthaul: CPRI 9.8304 Gbps links to RRHs carry I/Q with deterministic latency over long distances.
- Secure backhaul: Multiple uplink options to integrate with your L2/L3/IP/MPLS networks for transport to EPC/IMS and OSS/BSS
- Faster rollouts and O&M: Keep radios light on towers while concentrating power, cooling, and maintenance in one secure location.
- Lower total cost: Share baseband across sectors, reduce site hardware duplication, and streamline software lifecycle management.
