Multiple Input / Multiple Output (MIMO)

Thoughts about it

- in relation to Mobiles included💁

(No, this is not about MIMO in World of Warcraft Game 🎮😉)

Thoughts of arousal😉 (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 👇

MIMO is an antenna technology for wireless  communications in which multiple antennas are used at both the source (transmitter) and  the destination (receiver).

The antennas at each end of the communications circuit are combined to minimize errors and optimize data speed.

In as simple terms as possible🙂( 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 ...📕📔👩‍💻📱

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 devices📱💯.

Which enables the Gaming and mobile video possible🤸⚽🏀🏈🤳📱

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. 🧗🏊

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.

🧐🤓

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. ⚡🎮🛰️📡

- 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.

Done 🤷

Well .. you're welcome.

will try to do this in future too..
