MIMO Antennas - What is it and why would I use it?

MIMO Antennas

The acronym of MIMO stands for Multiple-In, Multiple-Out which is a communication style that sends the same packet of data as several signals simultaneously through multiple antennas. This data is split into multiple data steams when transmitted and are recombined at the receiver by another MIMO configured device that has the matching number of antennas. This style of communication still uses a single radio channel and is a form of antenna diversity which improves signal quality and strength for an RF link.

The receivers are typically designed to account for slight time differences in the receptions of each signal, prevent any additional noise or interference and even lost signals. Transmitting the same data on multiple streams introduces redundancy when transmitting data that traditional systems cant provide. This give MIMO some advantages over traditional antenna setups such as.

1. Overall throughput can be improved allowing for greater quality and quantity of data sent over the network. (Ideal for video content or other similar applications)

2. MIMO can help reduce issues like “fading” loses or dropped data packets.

3. Because MIMO uses multiple data packets and accounts for any disparity in signal reception, MIMO radios can utilize bounced and reflected RF transmissions to actually improve signal strength when direct line of site is not achievable.

MIMO systems also allow for ad-hoc networking where individuals can enter or leave the network at anytime and automatically forward data into the network. The ability to take advantage of this type of network makes MIMO systems ideal for a variety of user groups who need reliable, scalable network coverage. Such users can be.

1. Broadcast television such as live sports or news broadcasts where the video transmission location may move without notice (following players as they run up the pitch or follow the reporter as they move through a city) and MIMO prevents the need for long expensive cable runs.

2. Emergency services who are often thrown into chaotic situations and can’t always rely upon cellular to be available.

3. First responders to natural disasters where infrastructure has been damaged or completely destroyed.

MIMO systems come In a variety of form factors sometimes using multiple individual antennas however becoming increasingly popular and more common is the all in one antenna designed from the start to contain all of the antennas in one casing.

Have a need for MIMO antennas? or any other style of antenna?
