Thoughts about it
- in relation to Mobiles included๐Ÿ’
(No, this is not about MIMO in World of Warcraft Game  ๐ŸŽฎ๐Ÿ˜‰)


Thoughts of arousal๐Ÿ˜‰ (i.e Rise of interest in MIMO)

MIMO technology has aroused interest because of its possible applications in Digital television (DTV)
Wireless local area networks (WLANs),
Metro-politan area networks (MANs), &
Mobile Communications.

Simplified Definition should be told ๐Ÿ‘‡

In as simple terms as possible๐Ÿ™‚( not really but trying to...)

MIMO is a radio system that has multiple inputs and outputs and uses multiple antennas on both ends of the link. 
Several communication system algorithms and architectures fall under the broad category of MIMO, including 
Beamforming and massive MIMO
Modern LTE systems deploy a type known as "Spatial Multiplexing" 
This is often what the wireless industry refers to when the term MIMO is used.


MIMO working in mobile phone ...๐Ÿ“•๐Ÿ“”๐Ÿ‘ฉโ€๐Ÿ’ป๐Ÿ“ฑ
 When mobile phones are used in an urban area, the RF signal between the base station antenna and the handset often has to bounce off many buildings along the route.
This is called Multi-Pathing.
- A phenomenon that was in the past seen as being bad for good RF communications.

MIMO is a RF transmission technology that uses this reality to turn multi-pathing into a way to increase the data rates and data capacity of mobile devices๐Ÿ“ฑ๐Ÿ’ฏ.
Which enables the Gaming and mobile video possible๐Ÿคธโšฝ๐Ÿ€๐Ÿˆ๐Ÿคณ๐Ÿ“ฑ

MIMO connections get more use from the bandwidth available by using multiple channels. [This enables these(above mentioned) types of applications]

Now little in-depth into MIMO. ๐Ÿง—๐ŸŠ 
Instead of using a single channel, MIMO establishes multiple connections between a user and the network by using the same frequency band in two or four channels. MIMO does not avoid multi-pathing, but deliberately finds multiple paths for RF signals. 
MIMO can only work if multiple receivers, transmitters and antennas are installed into each mobile device. In a MIMO-enabled network, a mobile device will send and receive two separate wireless signals instead of one.
๐Ÿง๐Ÿค“

Real world Use

  • -MIMO connections use advanced signal processing algorithms and innovative engineering to avoid the negative effects of multi-pathing.
  • -At the same time, the speed at which users can watch videos, play games and access the internet is increased significantly. โšก๐ŸŽฎ๐Ÿ›ฐ๏ธ๐Ÿ“ก
  • - Vodafone Idea enhances 4G+ network connectivity through ma-MIMO (massive MIMO)-  deployments in Mumbai.
  • - Able to manage the huge increase in demand for data during the ongoing lockdown.
Recently:
  • -Samsung said that its lightning-fast 5G technology lab demonstration was made possible by combining two technologies, carrier aggregation and multi-user, multiple input, multiple output (MU-MIMO), to achieve 4.3Gbps speeds on each of two test mobile devices, reaching an industry peak speed of 8.5 Gbps.

here is a nice article about it ( post not sourced from it tho)

With massive MIMO, future 5G networks will be able to cram more data onto the same amount of spectrum
