Ericsson AIR 3246 B42 KRC161614/1

The Ericsson AIR 3246 B42 KRC161614/1 (Antenna Integrated Radio) is a high-performance, FDD (Frequency Division Duplex) Massive MIMO unit designed for macro cell deployments in 4G LTE and 5G NR networks. This integrated unit combines a 32-transmitter, 32-receiver (32T32R) radio with an integrated antenna array, optimizing spectral efficiency and coverage. 

Description for Ericsson AIR 3246 B42 KRC161614/1

The Ericsson AIR 3246 B42 KRC161614/1 allows mobile network operators, particularly in metropolitan areas with high traffic demands, to boost existing 4G capacity while providing a smooth transition path to 5G using existing mid-band FDD spectrum. The core feature is its use of beamforming capabilities in both the vertical and horizontal dimensions, enabling significant capacity gains (up to 3 to 5 times that of conventional 2T2R configurations in favorable scenarios). 
  • Technology: Supports FDD-LTE and is 5G New Radio (NR) ready through software upgrades. It was notably Ericsson’s first FDD radio for Massive MIMO.
  • Architecture: It has 32 transmit and 32 receive antenna branches connected to an array of dual-polarized antenna elements, enabling advanced multi-user MIMO (MU-MIMO) and single-user MIMO (SU-MIMO) functionality.
  • Design: It is a large, rugged outdoor unit with an IP65 rating, utilizing passive convection cooling (no fans).
