En Huawei BTS3900 is a next-generation, modular macro base station developed as part of Huawei’s SingleRAN solution. It supports multiple radio access technologies including GSM (2G), UMTS (3G), LTE (4G), and is also designed to be upgradeable for NR (5G) integration, making it one of the most future-ready platforms in Huawei’s RAN portfolio. The BTS3900 serves as a key component in dense urban, suburban, and even rural deployments where high capacity, flexible configuration, and simplified site installation are priorities.
One of the main advantages of the BTS3900 is its distributed architecture, separating the baseband unit (BBU) from the remote radio units (RRUs), enabling more flexible deployment strategies and easier adaptation to site-specific conditions. The platform also supports centralized baseband pooling, reducing the total number of baseband units needed across a site cluster. With full IP-based transport, high processing power, and multi-carrier capability, the BTS3900 is built to handle high traffic loads and rapid technological evolution.
As part of Huawei’s strategy for network convergence and energy efficiency, the BTS3900 uses advanced cooling, power control, and intelligent software to reduce operating costs. It remains widely deployed in both mature and emerging markets and continues to be supported by operators who value its reliability and upgrade potential. Carritech supports network operators using the BTS3900 by sourcing tested BBUs, RRUs, transmission modules, and other critical components through a trusted global supply chain.
Multi-RAT Capability: Simultaneous support for GSM, UMTS, LTE, and evolution toward NR (5G-ready when used with compatible BBUs and RRUs).
Distributed Architecture: Baseband and radio units can be deployed separately, enabling efficient use of space and optimal antenna placement.
Flexible Transport: Full support for IP-based backhaul and fronthaul, reducing reliance on legacy TDM infrastructure and enhancing scalability.
Centralized Baseband Pooling: Multiple cells can share processing resources, enabling more efficient use of baseband hardware and reduced power consumption.
Advanced RF Performance: High-output, multi-band RRUs support MIMO, carrier aggregation, and advanced modulation schemes for improved throughput and coverage.
Compact, Modular Design: Small footprint and scalable configuration allow for easy deployment in both existing and greenfield sites.
Energy-Efficient Operation: Intelligent power management, passive cooling options, and sleep mode capabilities reduce operational expenses.
High Availability: Designed with redundancy in mind—supports dual power feeds, redundant links, and carrier-grade uptime standards.
