Ericsson documentation shows that Radio 4415 B3 dimensions and weight vary by R-state. Earlier revisions are approximately 20kg without a fan, while R-state ≥ R5 variants are listed around 17.5kg without a fan.
Radio 4415 B3 operates in the 1800MHz / Band 3 spectrum.
Ericsson radio capability documentation states that the exact instantaneous bandwidth varies depending on R-state, software and radio mode. For KRC 161 637/1 with R-state ≥ R5, LTE operation can support up to 75MHz IBW for carriers of 5MHz bandwidth or higher.
Because capability differs between revisions, I recommend avoiding one fixed IBW figure in the main specification table unless you have confirmed the exact R-state of the stock batch.
The Radio 4415 B3 is designed to be installed close to the antenna, reducing feeder loss compared with traditional centralized RF architectures.
Typical functions include:
RF transmission and reception
4T4R MIMO operation
Optical connection to Ericsson baseband
Outdoor macro-site deployment
Multi-standard radio support
Network expansion and radio replacement
Ericsson describes Radio 4415 as part of a modular radio architecture that can be deployed in star or cascade optical configurations.

It is an Ericsson outdoor remote radio unit for Band 3 / 1800MHz networks, featuring a 4T4R architecture.
Common technical references list the KRC161637/1 as 4 × 40W, giving 160W total RF output.
The Radio 4415 product description includes NR among the supported technologies, but actual availability depends on R-state, software and network configuration.
Different R-states may have differences in hardware design, weight, installation options and radio capabilities such as IBW. Therefore, the exact R-state should be confirmed from the product label before ordering.
Yes. Actual product photos, labels and serial-number information can be provided for available units upon request.
Availability depends on current stock, but Linkworld Telecom has previously handled a 254-piece Radio 4415 B3 project, so this is a good product for you to emphasize bulk-supply capability on the page.
