Ericsson's AIR 6419 massive MIMO radio, which is designed for high rise and urban capacity sites, is coupled with a 64T64R antenna array that delivers up to 200 megahertz of bandwidth. To further increase the capacity, the number of radio branches can be also increased to 64, as in the AIR 6419 that I wrote about earlier this year. x][s7v~WC?lf

Space Requirements for Outdoor Installations, Space Requirements for Indoor Installations, 48 V DC or 100250 V AC Power Supply Interface, Antenna Integrated Radio Unit Description. The beamforming computation in Ericssons products is divided between the Massive MIMO panel and the baseband processing unit, which are interconnected using the eCPRI interface. Ericsson is selling multiple products with the same number of AEs, but different subarray sizes depending on the intended deployment area (whether there is a need for elevation beamforming or not).

The AIR unit has beamforming and MU-MIMO technology, capable to fully utilize. Firstly, it eases the deployment since a single engineer can carry it; in fact, there is a 25 kg per-person limit in the industry, which implies that a single engineer may carry one AIR 3268 in each hand (as shown in the press photo from Ericsson). This is unrelated to hybrid beamforming since each element is connected to the same radio branch and emits exactly the same signal. More precisely, the Ericsson Silicon in the panel is taking care of the mapping from data streams to radio branches, so that the eCPRI interface capacity requirement is independent of the number of radio branches.

The exact spacing is fine-tuned based on thermal and mechanical aspects, and also varies in the sense that the physical spacing is constant but becomes a different fraction of the wavelength depending on the frequency band used. 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. 3.

AIR 6488 multiplies the capacity of a 5G mobile network through the use of massive MIMO technology. If we take the AIR 3268 as a starting point, the coverage range can be improved by increasing the number of radiating elements to 192 and increasing the maximum output power to 320 W. The AIR 3236 in the coverage category has that particular configuration.
