How far along is the market Welcome to a Medical Battery specialist of the EXFO Battery

It is still very early in the development cycle for 8×8 MIMO and deployment of 4×4 MIMO. Most of the 8×8 MIMO development work is still in the research stage since there are a lot of practical issues that need to be resolved. For example, the physical space on a mobile handset is very limited, considering a DUT would need to have eight antennas in order to receive eight-layers or 8×8 MIMO transmissions. Additionally, these eight antennas would need to be spatially separated enough to ensure that they are uncorrelated from each other to enable the MIMO scheme to work adequately. Now, considering that most mobile handsets support multiple bands, and depending on which bands are used, this could also require additional sets of antennas.

Agilent’s solutions are specifically designed to mitigate the complexity of the challenge facing 8×8 MIMO device developers by offering standard-compliant solutions to measure device performance, yet are flexible enough to enable troubleshooting of systems and components.

Today, most people are only looking at aggregating two separate bands, each with a single component carrier. Since each of these component carriers could theoretically be configured for 8×8 MIMO capability, this would result in 16 antennas. You also have to consider the battery life required to simultaneously run this many radios in a single mobile handset. We’ll first start to see the industry using additional antenna systems on devices that have the resources to support them, i.e. laptops.

However, with regard to antenna systems, what is more realistic is using transmission mode 9 for the beamforming and multi-user MIMO capabilities. The base station has the resources to support eight antenna systems while the mobile handset does not and these eight antennas could be used to focus a single layer at a particular user location and this only requires one antenna at the mobile handset to receive or perhaps we take two layers for four layers, each directed at different users, again only required one antenna per mobile handset.

Agilent’s solutions are definitely advancing LTE. We already support Transmission Mode 9 with up to eight-layers, carrier aggregation, and the uplink enhancements like clustered SC-FDMA and the simultaneous transmission of the PUSCH and PDCCH (which was not available in Release 8 or 9 of the standard). In fact, today we can already generate carrier aggregation scenarios with two component carriers, including cross carrier scheduling, each simultaneously generating an eight-layer MIMO signal using Transmission Mode 9. This 8×8 MIMO solution provides early researchers access to test solutions to verify and troubleshoot early designs and monitor system performance. These solutions are scalable, so they can adapt as technology moves into product development and manufacturing. Agilent is monitoring, tracking, and participating in LTE standard development and we strive to bring solutions to market as early as possible to help those working on the newest generation of 8×8 MIMO devices get their products to market quickly.
