Ericsson radio units, RRUS and Radio-series RRUs

Ericsson identifies radio hardware by a product number rather than the marketing name, and both appear in this table. `KRC` prefixes remote radio units, `KRD` prefixes AIR antenna-integrated radios, and the trailing `/1` or `/2` is a variant rather than a quantity. In the marketing name, the first two digits of a Radio-series unit indicate the transmit and receive branch count — Radio 2217 is 2T2R, Radio 4415 is 4T4R, Radio 8863 is 8T8R — and the `B` suffix is the 3GPP band, so Radio 4415 B7 is a four-branch unit on band 7. Suffixes such as `R1A` or `R2B` are revision states, and a later revision is normally backward compatible but worth confirming against your software release.

Four things decide whether a radio unit will work on your site, and all four need to be on the purchase order: the 3GPP band, the transmit branch count, the output power per branch, and the baseband it must connect to. A Radio 4415 B3 and a Radio 4415 B7 are not interchangeable. Also confirm your RBS generation and software release — later radios frequently require a baseband and software level the older cabinets cannot provide. Tell us the unit you are replacing rather than only the one you want, and we will confirm the match before quoting.

The RRUS 01 to RRUS 32 family and the DTRU, DRU and RUS units are end-of-support; they are available as new surplus and refurbished stock only, and no manufacturer warranty applies. The Radio 2000 and 4000 series are largely end-of-sale but widely available. Radio 8000 units and AIR radios remain in production. Condition and lifecycle status are stated per line.
