I was recently invited to the Ericsson Imagine Studio to have a look atthe companys wide range ofMassive MIMOproducts. Table 1 Technical data for the EUT. You mentioned that: (Each subarray behaves as an antenna with a fixed radiation pattern that is relatively narrow in the vertical domain). One of the main take-aways from my visit to the Ericsson Imagine Studio in Stockholm is that the Massive MIMO product development has come much further than I anticipated. Downloadable images of Ericsson Network products The micro Radio 4408 is part of the Ericsson Radio System portfolio. Four vertically neighboring elements with equal polarization are connected to the same radio branch, which Ericsson calls a subarray. The technology plays an increasingly critical role in the evolution of 4G networks toward 5G, delivering the higher capacity, spectral efficiency, and faster speeds that operators and subscribers are demanding.

The reason for having a larger spacing in the vertical dimension is to obtain sharper vertical directivity, so that the radiated energy is more focused down towards the ground. Hagstrm also pointed out that a key novelty in 5G is the larger variations in capabilities between handsets, for example, in how many antennas they have, how flexible the antennas are, how they make measurements and decisions on the preferred mode of operation to report back to the base station.
