Billy Hogan, Principal Engineer at Ericsson, pointed out that the beamforming implementation is flexible in the sense that there are tunable parameters that can be revised through a software upgrade, as the company learns more about how Massive MIMO works in practical deployments. Maybe we (ZTE) should also invite you to one of our labs as were the 1st company to release Massive MIMO BSs (in 4G era). By using our services, you agree to our use of cookies. 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. Ill r`nats rmsmrvmg. Total time-averaged power delivered to the antenna: 55.3 dBm. (TCO 1) Block encoding takes several _____ and sends them out as a new code word. BR Berthold Ruth. What is the Purpose of Asymptotic Analysis? AIR 6488 is a 64TR TDD AAS for NR. 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.

Ericsson AIR 6488 - ERICSSON | TelecomEasy,Espaol PDF EMF Test Report: Ericsson AIR 6419 B77G NR (FCC) Table 1 Technical data for the EUT. Based on US GAAP (section 605), is it appropriate for CoAx to recognize revenue. This was not the case a few years ago, and demonstrates the product evolution. Seals that have been implemented by Ericsson must not be broken or, AIR 6488 is a 64TR TDD AAS for LTE and NR, operating as standalone, as split, mode, or as mixed mode. How Much does Massive MIMO Improve the Spectral Efficiency? Four vertically neighboring elements with equal polarization are connected to the same radio branch, which Ericsson calls a subarray. All trademarks mentioned herein are the property of their respective owners. >%k%4y\B UPgpbV(D{,W/@DDUQ# I think 8 users with two spatial streams per user (different polarization) is the realistic upper bound for these panels. <> 1. AIR 6488. A radio branch consists of filters, converters, and amplifiers. The AIR unit has beamforming and MU-MIMO technology, capable to fully utilize radio resources in both azimuth and elevation. We enable the full value of connectivity by creating game-changing technology and services that are easy to use, adopt, and scale, making our customers successful in a fully connected world.

Ericsson AB AKRD901206 EMF Test Report: Ericsson AIR 6449 B77D NR (FCC 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. In the meantime, these Massive MIMO panels will deliver higher single-user data rates throughout the coverage area than previous base stations, thanks to the stronger and more flexible beamforming. In your view, what would be the typical number of users per sector that one would try to spatially multiplex using such a panel in heavy traffic scenarios? Apologies for asking too many questions. AIR 4435. 1. FaFAOX], Document Includes RF Exposure Info EMF Test Report: Ericsson AIR 6488 B48 LTE (FCC). PDF EMF Test Report: Ericsson AIR 6449 B77D NR (FCC) Great article! Two installation scenarios are shown below. With the Radio 4408, Ericsson evolves the micro radio portfolio to become even more flexible thus making it easier than ever to make small and efficient single and multi-band micro radio installations. The total energy consumption is reduced by 10% in the new product, compared to its predecessor. 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. Ericsson shall, have no liability for any error or damage of any kind resulting from the use of this. B43). 4. Product Files AIR 6488 is a 64TR TDD AAS for NR. endobj I suppose the signal processing for estimation and beamforming has also been refined. Also what is the minimum deactivation and activation time for the analog component switching off and on. BR Berthold Ruth. Ho Chi Minh City University of Technology. There are multiple reasons why the weight of a Massive MIMO array matters in practice. 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). Maximum output power and number of radiating elements, which jointly determines the. Thanks for bridging the gap between academia and industry in the area of massive MIMO. 4 0 obj thanks a lot for this very insightful post! AIR 6488 Radio Description.pdf. There are then different products depending on what output power, bandwidth, and EIRP that one wants to support. If the industry can already build 64 antenna-integrated radios into a box that weighs less than 20 kg, then one can certainly build even larger arrays, when there will be demand for that. The usual situation of ugly, bulky equipment in public spaces is avoided by replacing it with a single self-contained unit. The AIR is designed for outdoor use, intended for pole, wall, or rooftop mounting. Thanks to its unobtrusive design, the AIR 6488 blends seamlessly into public spaces. As far as I understand by using subarrays in vertical domain the Tilt will be fixed (a subarray normaly doesnt use phasesifters) e.g.
