简要描述：
RRU 2212B3 (KRC 161 496/1 or KRC 161 496/2)Buy the Ericsson RRU 2212B3 (KRC 161 496/1 or KRC 161 496/2) — a high-performance 1800 MHz (Band 3) remote radio unit supporting 2×2 MIMO, 2×80 W output power, and LTE FDD / GSM 1800 operation.Compatible with Ericsson Baseband 5216, 6630, and 6648, ideal for macro site deployments, capacity expansion, and multi-band network modernization.
The Ericsson RRU 2212B3 is a remote radio unit (RRU) designed for 1800 MHz Band 3 applications in Ericsson’s macro base station systems.
It belongs to the Radio 2212 family, which is known for its compact outdoor design, low power consumption, and high reliability.
The RRU 2212B3 supports LTE FDD and can be used in GSM/WCDMA + LTE multi-standard configurations depending on the software license and system version.
It is commonly deployed in macro sites for capacity enhancement and coverage expansion.
| Parameter | Specification |
|---|---|
| Operating Band | Band 3 (1800 MHz) |
| Uplink Range | 1710 – 1785 MHz |
| Downlink Range | 1805 – 1880 MHz |
| Transmit/Receive Paths | 2 × 2 MIMO (2T2R) |
| Typical Output Power | 2 × 80 W per channel (reference value for Radio 2212 series) |
| Supported Technologies | LTE FDD, GSM 1800, WCDMA Band 1/3 (depending on configuration) |
Note: Ericsson’s Radio 2212 B3 units are typically labeled KRC 161 496/1 or KRC 161 496/2. Actual power and configuration should be confirmed from the unit’s nameplate.
| Interface | Description |
|---|---|
| Optical Interface | CPRI-based connection to Ericsson Baseband (e.g., Baseband 5216 / 6630 / 6648) |
| Electrical Power | DC −48 V nominal (via outdoor power cable) |
| Cooling | Passive / active air cooling (depending on ambient installation) |
| Mounting Options | Pole, wall, or tower mounting using standard Ericsson outdoor brackets |
Compatible Basebands: Baseband 5216, Baseband 6630, Baseband 6648, Baseband 6000 series
Integration: Supports direct fiber (CPRI) connection for flexible deployment — star, chain, or ring topology.
Deployment Type: Outdoor macro cell; near-antenna installation reduces feeder loss and improves signal efficiency.
Software Support: Works with RBS 6000 / Ericsson Radio System (ERS) software releases for LTE and multi-standard operation.
| Parameter | Specification |
|---|---|
| Form Factor | Outdoor remote radio unit |
| Protection Level | Weather-sealed design (typical IP65 class for Ericsson macro RRUs) |
| Operating Temperature | −40 °C to +55 °C (depending on deployment height and cooling) |
| Installation | Single-person mountable; lightweight aluminum chassis optimized for tower deployment |
Each RRU 2212B3 unit undergoes:
Port and VSWR inspection
Power output and EVM testing
Optical and CPRI link validation
Software and license compatibility check
Before delivery, units are refurbished and tested to ensure full compliance with Ericsson network standards.
