MU MIMO wi fi performance and gaming tested. Some technologies have a clear and direct impact on your gaming experience, like your graphics card or processor. Others are a bit more nebulous, like networking standards and technologies. Take MU MIMO for example, the multi user, multiple input, multiple output wireless networking technology that was introduced with 8.

Its firmly in the latter category of technologies whose impact may not be as readily apparent. Were going to look at the pros and cons of the standard, and show who will benefit most from having a MU MIMO enabled network. In my article How to set up your home network for optimal gaming performance, I discussed the network requirements for gaming and concluded that for a gaming network, its not so much about high bandwidth requirements, but more about dedicated, low latency bandwidth. Online PC gaming is all about delivering a relatively small but steady flow of data back and forth to the gaming client. Ideally this is done via a wired connection, but plenty of PC gaming is done over wireless connections due to the physical constraints of many homes. Remember to get your next house prewired with CAT 7 going to every room Combined with improving wireless speeds, however, wired connections arent absolutely necessary, and new technologies like MU MIMO can further improve the situation. One major difficulty for wireless gaming is that there are often multiple simultaneous processes happening across the network. Netperf Windows 7 Download' title='Netperf Windows 7 Download' />Its not just the gaming PC, but also the proliferation of additional clients, including tablets, smartphones, and media boxes that are connected to a single router in most households. While todays higher end routers should be able to handle dozens of simultaneous connected clients, dividing the bandwidth so many ways can degrade the experience for all the devices. If youve experienced problems trying to play a game while other household members are streaming HD Netflix, you know what were talking about. Strike Fighters 2 Israel. The previous SU MIMO single user, multi in, multi out standard dates back to 2. Such routers send all data out to all of the wireless clients, and the clients filter which network packets are for them and which are for someone else. Netperf Windows 7 Download' title='Netperf Windows 7 Download' />As the number of wireless clients increases, this becomes increasingly inefficient and wastes precious bandwidth. Each device on the network sends and receives its own data, as well as all the traffic from the other devices. Gaming at the same time as other high bandwidth activities are going on becomes increasingly compromised an older SU MIMO routers. MU MIMO was introduced in 2. Wave 2 8. 02. 1. With a MU MIMO enabled router, data can be directed to the client that needs it, in essence giving each client its own dedicated router. Netperf Windows 7 Download' title='Netperf Windows 7 Download' />A MU MIMO router can serve up to four simultaneous clients in this fashion one per 1. By sending the data directly to the client, and only the client that needs it, the entire network becomes more efficient. Theres less wasted data and less interference, resulting in overall significantly higher network throughput. While MU MIMO is an impressive networking technology, there are limitations that should be kept in mind. Support for packages has been discontinued on Sunfreeware. Please Visit our New Website UNIXPackages. UNIX packages provides full package support for all levels. UCL Software Database Please note that the Software Database will need essential maintenance work on December 7th 2017, between 8am and 10am. During this time, the. A crucial one is that MU MIMO in the current iteration only works on the download side of the equation. That means that MU MIMO does nothing to improve the upload speeds, which are also important for PC gaming. Furthermore, MU MIMO is limited to a maximum of four simultaneous clients, and no router can currently go beyond that number. Although the router can connect to additional devices, they will be served in a SU MIMO fashion. This isnt necessarily a major problem, however, unless you have more than four active clients at a time. There are other constraints as well, like the fact that this technology only works on the 5. GHz frequency. Any devices on the older and generally still more common 2. GHz frequency cannot benefit from a MU MIMO router. This is largely due to the 2. GHz spectrum already being full of interference, which comes from the wider transmission range for 2. GHz signals. Finally, and perhaps most critically, its not just the router that needs MU MIMO support, but the client needs it as well. This last limitation is perhaps one of the biggest stumbling blocks to more widespread implementation of MU MIMO. While there are quite a few routers that support MU MIMO, there are few client devices that currently implement the technology. Currently, the clients that support MU MIMO include the Killer NIC internal adapter, and the Linksys Max Stream AC6. Edimax AC1. 75. 0 USB adapters. That presents some difficulties when it comes to testing and demonstrating MU MIMOs capabilities. We need multiple clients running simultaneously, preferably with steady loads. That makes this more complicated than typical router or client performance metrics that focus on throughput speeds between a single router and client. A green arrow in the lower left part of the image indicates where the MU MIMO feature is controlled. Our goal is to measure simultaneous throughput across multiple clients, while toggling MU MIMO support on and off. Just to clarify, the goal is to measure the performance of the local network, not the internet speed. We used Netperf, which is designed to fully load the network connections and measure the throughput. We use a version with a custom overlay for ease of use. On the hardware front, we have three test clients using different wireless adapters. Note that only one of the clients actually supports MU MIMO, but well revisit this topic as we receive future adapters. MSI gaming notebook with Killer NIC Wireless Adapter AC1. Killer Wireless AC 1.

MU MIMOOur test router is the Netgear Nighthawk X4. S, which supports MU MIMO and allows the feature to be easily enabled and disabled via the router software. In addition, the Nighthawk X4. S is our pick for the Best Gaming Router. Netperf requires the use of a server computer, and a Windows 8. Gigabit Ethernet port is connected to the router with a short CAT 5e cable. The Netperf software can run as a server or client, and it measures the bandwidth. All clients are connected to the network via the 5. GHz frequency as required for MU MIMO to function, at a distance of 3 meters, with line of sight to the router and no obstructions. The clients are connected two at a time and Netperf is run on them simultaneously. Three runs are completed and we report the result for the best run. Testing is done with MU MIMO enabled and disabled on the router to assess the impact of MU MIMO. As discussed in the previous article, How to set up your home network for optimal gaming performance, the Killer NIC software is enabled on the gaming computer, and the routers Qo. S was enabled as well using a manual configuration tuned for optimal performance, with gaming as the highest priority on all settings. The results of our testing demonstrate the effect of using MU MIMO on a network loaded with traffic. Of the three clients tested, only the Killer NIC supports MU MIMO, and network throughput is more than doubled actually 1. There is an almost negligible improvement in performance with MU MIMO on the other two adapters as well, though with wireless testing its within the margin of error.
