Here, the complexity lies in finding a pair of devices whose channel conditions allow the use of this feature. Multi-User MIMO: 2×2 MIMO for 2 users simultaneously, meaning the same set of resource blocks is used for 2 different users with 2 different streams each.This results in a slightly higher data rate for the user, because the transmission is more robust (a higher modulation and coding scheme (MCS) can be applied). Transmit diversity: 2×2 MIMO is used where each of the 2 transmit signals (streams) is transmitted via 2 Tx antennas.The 4 Tx RF chains in base stations can be used for the following features that only require 2×2 MIMO capable devices: What we can say today is that the issue with 4 uncorrelated receive antennas in a form factor of a smartphone is unsolved yet.Īlthough 4×4 MIMO capable devices are not yet available, 4 Tx (transmitter) antennas on the base station side have been frequently deployed in the past months. In the past years, the availability of 4 Rx (receiver) capable devices has been and still is impeding the commercial deployment of 4×4 MIMO. This is perfect for 2×2 MIMO, but not applicable for 4×4 MIMO. smartphones) include only 2 receive paths and 2 antennas. Currently commercially available devices (e.g. A new type of user equipment is necessary. To receive 4 streams (different signals), the UE requires 4 receive paths and 4 uncorrelated antennas. And even though it is certainly possible to mount the 2 antenna columns closer to one another, the imperfect decorrelation would significantly compromise MIMO gain. The distance, equal to 10 times lambda (3.80 m in 800 MHz or 1.70 m in 1800 MHz), between the 2 antenna columns would have a severe impact on the base station site installation.

To get full decorrelation between these 2 antenna columns, however, we would need a distance of at least 10 wavelengths between them. This means they are uncorrelated.īy using 2 cross-polarized antennas, 4 uncorrelated paths with 4 antennas can be realized. The 2 polarization directions are orthogonal to each other. Base stations are typically using cross-polarized antennas (normally slanted at +45/- 45 degree for the 2 polarization directions). Today in LTE networks, 2×2 MIMO is state–of-the-art.
1blocker better than just an adblock 1 4. In theory, this doubles the downlink throughput per resource block compared with 2×2 MIMO, today's state-of-the art MIMO operating mode. To receive the signals and benefit most, however, the UE must be equipped with 4 antennas as well. MimoLive live editing allows you to cut down on.Ĥ×4 MIMO means that with exactly the same resource blocks on the air interface, the base station transmits 4 different signals (or streams) via 4 transmit antennas to one user equipment (UE). The only problem is - it takes a lot of time and effort to produce. MimoLive is a multi-in, multi-out live video engine. The mimoLive application comes with powerful broadcasting and real-time editing capabilities and can pair up with some of the most popular streaming.

MimoLive is a video streaming software solution that is the successor of a rather popular title (BoinxTV) developed by the same company (Boinx Software).It enables you to switch multiple cameras, insert presentations, add layered graphics like weather maps, lower-thirds, social media feeds, green screens, and much more. MimoLive is the all-in-one video encoder, switcher and streaming software for Mac.The feature builds on uncorrelated paths In other words, it builds on uncorrelated transmit and receive antennas and uncorrelated paths (multipaths) on the air interface (the channel). It enables the transmission of more than 1 signal to 1 user via the same set of air interface resources. MIMO stands for Multiple Input Multiple Output and can also be described as spatial multiplexing. It is only now that operators are planning 4×4 MIMO deployments. 3GPP's (3rd Generation Partnership Project) latest Release 13 is currently frozen. MIMO is fundamental in LTE system designĤ×4 MIMO has already been specified in the 3GPP Release 8, the first LTE standardization release, frozen in 2008.
The potential of this specific operating mode lies in enabling radio systems to achieve significant performance gains by using multiple (4) antennas at their transmitters and receivers.

The second part of this series discusses higher order MIMO antenna configurations, particularly 4×4 MIMO. In the first part of this series, we provided an overview of the hardware-related capacity enhancing features and discussed carrier aggregation in detail.
The various macro network enhancements available today offer a cost-efficient and smart approach for capacity increase in mobile networks.
