AIR 6488 multiplies the capacity of a 5G mobile network through the use of massive MIMO technology. In hybrid beamforming, an antenna element is connected to multiple radios. Anywhere. Antenna Integrated Radio Unit Description. B43). 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 5G standard specifies protocols but leaves the door open for both clever and less sophisticated implementations. 1 0 obj Ericsson is one of the leading providers of Information and Communication Technology (ICT) to service providers. -48 VDC 3-wire. The purpose of the computational split is to reduce the fronthaul signaling by exploiting the fact that Massive MIMO transmits a relatively small number of data streams/layers (e.g., 1-16) using a substantially larger number of radios (e.g., 32 or 64). 159.89.202.53 Episode 33. 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). ,#~]ipB6+h#QPtQZMtD`$0Q.hN]Xdh_wS?Lv,g 0:s5 %PDF-1.7 Your email address will not be published.

BR Berthold Ruth. 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. Ericsson - Winncom Turning off components is not as simple as it sounds, since it must be possible to turn them on again in the matter of a millisecond so that coverage and delay issues are not created.

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). It has a maximum IBW of 100 MHz and maximum transmitted power of 80 W (200 W for B41K, B42, B42F, B42G, and B43). The AIR unit has beamforming and MU-MIMO technology, capable to fully utilize radio resources in both azimuth and elevation. For the power levels specified in the table with tolerances added, and the upward rounding of compliance boundary dimensions to the nearest decimeter, the specified results are conservative. Ericsson AB 2020. This is unrelated to hybrid beamforming since each element is connected to the same radio branch and emits exactly the same signal. The main benefits compared to previous macro solutions are improvements in: Enhanced coverage - High gain adaptive beamforming Enhanced capacity - High-order spatial multiplexing and multi-user MIMO INGENIERIA CIM100.

The AIR unit has beamforming and MU-MIMO technology, capable to fully utilize. It is actually the same silicon that is used in all the current Massive MIMO products. However, there is a new software feature called Deep Sleep, where power amplifiers and analog components are turned off in low-traffic situations to save power. Ericsson Teases Massive MIMO 5G Radios For Late 2021 According to Mns Hagstrm, Senior Radio Systems Architect at Ericsson, there are no low-hanging fruits anymore in the hardware design since the Massive MIMO product line is now mature. You mentioned about Deep Sleep. Your IP: The unit is equipped with two warranty seal stickers. Required fields are marked *. AIR 6488 multiplies the capacity of a 5G mobile network through the use of massive MIMO technology. In hybrid beamforming, an antenna element is connected to multiple radios. Anywhere. Antenna Integrated Radio Unit Description. B43). 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 5G standard specifies protocols but leaves the door open for both clever and less sophisticated implementations. 1 0 obj
Ericsson is one of the leading providers of Information and Communication Technology (ICT) to service providers. -48 VDC 3-wire. The purpose of the computational split is to reduce the fronthaul signaling by exploiting the fact that Massive MIMO transmits a relatively small number of data streams/layers (e.g., 1-16) using a substantially larger number of radios (e.g., 32 or 64). 159.89.202.53 Episode 33. 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). ,#~]ipB6+h#QPtQZMtD`$0Q.hN]Xdh_wS?Lv,g 0:s5 %PDF-1.7

Aside with analog component switch-off what is the additional power saving achieved over and above PA switch-off. BR Berthold Ruth. 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. Ericsson - Winncom Turning off components is not as simple as it sounds, since it must be possible to turn them on again in the matter of a millisecond so that coverage and delay issues are not created.

That would mean this concept is also more cost efficient, because each subarray can be adapted to a certain enviroment such as urban, rural etc.. For example, in rural areas the subarray will have a narrower beam created by more antenna elements (e.g.8AE ) and in an urban area the vertical-beam would be less narrower (e.g.4 AE) known as angular coverage.
