Internet connectivity is increasingly playing an
essential role in all of our lives today. To enjoy the best of the internet,
it’s vital that we own the appropriate connectivity devices. Perhaps the most
important of them all is the router. The router is responsible for managing the
devices and internet signal. It has the responsibility of managing several
devices on a network, while also providing optimal internet connection. To
achieve this goal, the routers are incorporated with specialized algorithms and
techniques such as the MU-MIMO.

Otherwise referred to as MU-MIMO, this is a set of
several multiple-input and multiple-output (MIMO) resources to support wireless
internet connections. The setup often involves a set of users or wireless
devices, which have one or many antennas, that are involved in communication.
Furthermore, the single MIMO includes a single multi-antenna transmitter that
is equipped with a single multi-receiver antenna. While MIMO technology
involves expensive signal processing, it can make effective use of spatially
distributed transmission technologies. However, the single-user MIMO only
involves the several antenna dimensions of a local device. Special algorithms
are produced to help enhance the MIMO systems when many terminals require
connections.

How
MU-MIMO Works With Wireless Devices

The MU-MIMO technologies were developed to improve
connections where several terminals require access to a wireless network at the
same time. The basis of the 802.11 protocol, is that terminals gain access to
the wireless network in order. If multiple devices request access the router at
the same time, this can lead to a bottleneck of resources. The router has to
determine the best way to address the requests of all these users. Moreover, it
also has to regulate the connection quality. In some cases, the burden
increases when other devices such as smartphones seek access to the router.
However, the MU-MIMO technology plays a significant role in eliminating this
issue.

Caveats
of MU-MIMO

MUMO technology works in a few various methods. In
particular, the technology works by dividing the internet connection into
specific individual streams. The devices will then share the internet
connection equally. The MU-MION router can be available in either the 2×2, 3×3
or 4×4 configurations. These refer to the number of streams the router can
produce at any given time. The MU-MIMO technology is simple to a car wash,
whereby cars get washed after the people ahead of you get their car cleaned.
With MU-MIMO, instead of one carwash port, there are several ports, and as many
as four vehicles can be washed at the same time.

However, there are some important rules to consider
before leveraging the benefits of this technology. Among some of these significant
benefits include:

Devices Don’t Require Several Antennas

Similar to SU-MIMO technology, only devices that are
developed to support the MU-MIMO technology can access the given signals.
However, unlike SU-MIMO, wireless devices don’t need to have several antennas
to access the MU-MIMO signals from the router. Even devices that have one
antenna can still access the MU-MIMO signal. A device with several antennas
would be able to access various types of streams at the same time. Such a
benefit would play a significant role in improving the performance of the
Wi-Fi. That said, a device with several antennas requires more space and power,
and this might affect the cost.

Access Points are Responsible for Much of the Workload

Designed to eliminate the caveats for terminals to
access a signal, the access points in the MU-MIMO technology are responsible
for processing most of the signals. This is one of the main benefits over the
SU-MIMO technology – where most of the bulk of signal processing goes to the
devices. This way, brand manufacturers have improved freedom in terms of the
diversity of features they can incorporate in a router.

It only Works on the 5 GHz Wi-Fi Band

While the SU-MIMO can work both in the 2.4GHz and 5
GHz Wi-Fi bands, the MU-MIMO is not so dynamic. The wireless routers are only
able to accommodate several terminals on a higher bandwidth level. However, the
lower and more congested bandwidth can`t leverage the benefits of the
technology. The only issue is that not many users have reliable access to high
quality internet.

MU-MIMO Does Not Support Infinite Streams or Devices

Even if most users want a router than support multiple
devices, this wouldn’t be feasible due to the high levels of traffic and
congestion. As such, an MU-MIMO router or access point is not able to deliver
an infinite number of streams. A conventional router or access point often has
a maximum limit of about five devices, that it can serve at any given point.
That said, the MU-MIMO router can send different streams to different devices.
For example, a four-stream device can serve as many as four devices at the same
time.

Why is MU-MIMO Important When Buying a Router?

Similar to investing in any form of I.T technology, it’s
crucial that you make informed decisions for the best user experiences. In
particular, it’s essential to consider the MU-MIMO protocol because it will
allow you to enjoy reliable internet connectivity. With a traditional SU-MIMO
router, you might have had to wait for the request from your terminal to be
processed gradually. Furthermore, most of the workload in processing internet
signals is done by the access point. This way, brand manufacturers have more
“space and freedom” to incorporate routers with enhanced features. However,
there are some downfalls to owning the MU-MIMO router, though not significant.
For instance, you can only enjoy the benefits of such technology of the 5GHz
band signal.

Conclusion

Overall, ever since the advent of Wi-Fi, the typical functionality
of supporting devices such as routers and access points has evolved
significantly. Gone are the days when you had to struggle to get a reliable
internet connection from your home or office router. A good MU-MIMO router lets
several devices enjoy quality internet connectivity, and without any
bottlenecks. Thus, you can experience improved productivity or internet access,
as your router provides reliable connectivity.
