The Ericsson Radio 2203 B3 (part number KRC161488/1) is a high-performance remote radio unit (RRU) designed for outdoor deployment in cellular networks. It forms part of the Ericsson Radio System portfolio and supports both LTE and WCDMA technologies. With its compact form factor, flexible mounting options and robust build, it is ideal for urban or suburban sites, small-cell installations or retrofit upgrades. This unit helps network operators deliver reliable coverage, capacity and quality in demanding conditions.

Key Features

• Supports mixed-mode operation of LTE and WCDMA, enabling legacy and modern network coexistence

• 2T/2R MIMO architecture to increase spectral efficiency and overall throughput

• Output power of up to 2 × 5 W, suited for Band 3 (1800 MHz) and similar deployments

• Two antenna ports (4.3-10 female) and CPRI optical interface (2 × 2.5/5/10 Gbps) for flexible connectivity

• Outdoor-rated IP 65 enclosure, capable of operating from –40 °C to +55 °C and mounting on wall or pole

• Compact size (<4.5 kg, approx. 200 × 200 × 100 mm) for easier installation in constrained sites

Technical Specification Highlights

• Supported bands include 3GPP Bands B1, B3 (incl. B3C), B7, B8, B66A, B5 and B2/B25

• Up to four WCDMA carriers or up to 45 MHz LTE bandwidth in suitable bands

• Antenna interface: 2 × 4.3-10 (female) ports

• CPRI links: 2 × 2.5/5/10 Gbps via SFP modules

• Power supply options: –48 V DC or 100-250 V AC

• Mechanical: approx. 200 mm × 200 mm × 100 mm (including bracket), volume ~4 L, weight <4.5 kg

• Environmental: Humidity 5–100 % and full outdoor class IP65 rating

Usage & Application
This unit is well suited for telecom operators, system integrators and infrastructure providers who need a reliable RRU for deployment in urban rooftops, lamp-poles, towers or small-cell sites. Because of its small size and dual-mode support (LTE + WCDMA), it is particularly useful in network densification, urban micro-sites or multi-band, multi-sector configurations. It can be used in new site builds or as an upgrade path in existing sites, enabling enhanced capacity and coverage without extensive footprint or power demands.
