MIMO allows multiple streams of data to be sent in parallel. Unlike other home Wi-Fi mesh systems, all AmpliFi Routers and Mesh Points use 3-stream MIMO, allowing three streams of data to be sent to a supporting device.
Many argue that most client devices are either 1-stream SISO or 2-stream MIMO and that only higher-end devices like Apple’s MacBook Pro support this technology.
In this blog post, we look at how the AmpliFi system provides a performance boost for all devices: from single-stream smartphones to high-end 3-stream laptops.
Speed and Time
When driving from point A to B, we know that faster speeds translate to lesser time.
Wireless networks work similarly: The same amount of data takes less time to transfer when using higher wireless speeds.
3-stream MIMO offers a 50% boost in transfer rates, compared to 2-stream MIMO (1.3 Gbps versus 866 Mbps).
Hence, a 3-stream client will be able to transfer the same amount of data in 50% less time than a 2-stream client.
How does that help 2-stream and 1-stream clients?
The AmpliFi Wi-Fi system typically serves several devices, such as smartphones, laptops, cameras, thermostats, etc.
Since a 3-stream device takes 50% less time, the savings can now be distributed to other devices, and more time for them means:
They can transfer more data.
More devices can be served.
Faster Mesh = Faster Everything
So what if you don’t have a 3-stream client device, is AmpliFi still able to boost network performance? Yes, see below:
In the figure above, we have the AmpliFi Router serving the Mesh Point in the bedroom, which is relaying to the Mesh Point in the backyard. The client devices in the example are either 1-stream (the Wi-Fi camera) or 2-stream (the smartphone and tablet).
Since the Mesh Points use 3-stream MIMO, transferring data between the Amplifi Router and the Mesh Points or between Mesh Points takes 50% less time compared to an equivalent 2-stream solution.
This allows the AmpliFi system as a whole to increase performance for the smartphone, tablet, and single-stream Wi-Fi camera.
Longer Range and Better Connectivity
With 3-stream MIMO, AmpliFi can use three antennas to transmit wireless data, regardless of the number of streams supported by the client device.
This provides 50% increased range (as compared to a 2-stream Wi-Fi system), due to:
Multiple data copies are sent.
Wireless networks are prone to interference and information loss. Just like having a disk backup helps in recovering lost data, the AmpliFi system replicates the information across all three antennas when sending data to clients.
This technique is called Cyclic Delay Diversity (CDD) or Cyclic Shift Diversity (CSD).
The wireless transmission is focused more in the direction of the client.
Known as Beamforming, this allows us to dynamically focus the wireless energy in the relative direction of the client device.
This boosts the range of your home Wi-Fi network and minimizes interference to and from other devices.
Data received from multiple antennas.
When a client device such as a smartphone or tablet transmits information back to the AmpliFi system, AmpliFi takes the best bits of information from each of the three antennas and automatically combines them. The technical name for this process is Maximal Ratio Combining (MRC).
This is especially useful with Wi-Fi cameras: the direction of traffic is primarily from the camera to the AmpliFi system. This keeps the video flowing smoothly.
