Ericsson Radio 4490 KRC161745/1 B1B3 4T4R FDD-LTE 400W
Description and Specifications of Ericsson Radio 4490 KRC161745/1
The Ericsson Radio 4490 KRC161745/1 B1B3 is a high-performance, dual-band Remote Radio Unit (RRU) and a key component of the latest Ericsson Radio System (ERS) generation. It is engineered for mid-band FDD (Frequency Division Duplex) capacity layers, with a strong focus on maximizing energy efficiency and reducing site deployment costs.
Technical Description of Ericsson Radio 4490 KRC161745/1 B1/B3
- Mode & Bands: The unit is a Dual-Band FDD radio, simultaneously supporting two crucial capacity bands:
- Band 1 (B1): 2100 MHz (High-speed LTE/NR layer)
- Band 3 (B3): 1800 MHz (Primary 4G/5G FDD capacity layer)
- It is a Multi-Standard Radio (MSR), supporting GSM, WCDMA, LTE, and is 5G NR-Ready via software (e.g., Ericsson Spectrum Sharing – ESS).
- MIMO Configuration: It features 4 Transmit / 4 Receive (4T4R) capability per band. This allows operators to leverage high-capacity 4*4 MIMO on both the 1800 MHz and 2100 MHz spectrum layers using a single unit.
- Key Advantage (Efficiency): The Radio 4490 series is designed for industry-leading energy performance. It significantly reduces power consumption and weight compared to previous high-power dual-band radios (like the 4480), lowering OPEX and easing site installation (less wind load, easier climbing).
- Design: It is compact, rugged, and uses passive (convectional) cooling for high reliability and quiet operation.

Comparison of Ericsson B1B3 Dual-Band Radios
The comparison, as radios represent the evolution of Ericsson’s dual-band FDD portfolio for the common 1800 MHz (B3) and 2100 MHz (B1) capacity layers.
The key differences lie in their MIMO capabilities, output power, weight/size, and crucially, the number of sectors they can serve.
| Feature | Radio 4443 B1B3 | Radio 4480 B1B3 | Radio 4490 B1B3 | Radio 6626 B1B3 |
| Primary Design Focus | High-Capacity, Standard RRU | High-Power, Standard RRU | Latest Generation, High-Efficiency | Three-Sector Consolidation |
| TX/RX Configuration | 4T4R per band | 4T4R per band | 4T4R per band | 6T6R (3 Sectors $\times$ 2T2R) per band |
| Antenna Ports | 4 Ports Total | 8 Ports Total (4 per band) | 8 Ports Total (4 per band) | 6 Ports Total |
| Sectors Supported | 1 Sector | 1 Sector | 1 Sector | 3 Sectors (Radio covers entire site) |
| Frequency Range | Dual-Band FDD: B1 (2100 MHz) / B3 (1800 MHz) | Dual-Band FDD: B1 (2100 MHz) / B3 (1800 MHz) | Dual-Band FDD: B1 (2100 MHz) / B3 (1800 MHz) | Dual-Band FDD: B1 (2100 MHz) / B3 (1800 MHz) |
| Max Nominal Output Power | 2*40 W per band (Total 160 W or higher) | 4*60 W per band (Total up to 400 W) | 4*100 W total (Shared/Flex power) | 720 W Total (Split across 3 sectors, e.g., 3 2*120 W) |
| Cooling | Passive | Passive (Optional Fan for Higher Power) | Passive (Natural Convection) | Passive (Natural Convection) |
| Weight | 30 kg | 33 kg | 23 kg (Key differentiator in newer generation) | 48 kg |
| Key Advantage | Early generation 4T4R capacity upgrade. | High power 4T4R for superior coverage and capacity. | Superior Energy Efficiency and significantly lower weight. | Site Simplification: Replaces 3 separate dual-band radios. |
Key Takeaways from the Comparison
Radio 4443 vs. 4480:
- The 4480 is essentially the high-power successor to the 4443, offering substantially more output power (up to 400 W total) for better coverage and cell-edge performance in a single-sector setup.
Radio 4480 vs. 4490:
- The 4490 is the latest generation, maintaining high-power capability (often supporting dynamic power sharing up to 400 W) but achieving massive reductions in size, weight, and energy consumption compared to the 4480. This is crucial for tower loading and operational expenditure (OPEX).
Radio 6626 (The Outsider):
- The 6626 is a completely different product, designed for site consolidation. Instead of being a single-sector radio, it contains the processing power and RF chains for three full sectors in one box. This simplifies cabling, reduces the number of units on the tower from three to one, and provides immense power output capability, though its weight is the highest as it integrates three radios worth of components.
