Number of Increased Antennas of Routers: Is Marketing Cheat, Technical Requirement?

The new routers offered by brands each year have more antennas than the previous one and exits the market. Is this physical proliferation that draws attention on the shelf, really increases the internet speed and performance, or is it a visual strategy to influence consumers only? The answer is more technical and interesting than you can guess.

There are several important reasons behind the increase of antenna number on the routers:

-MIMO technology: Modern routers use MIMO (Multiple-Input Multiple-Output) systems, which can simultaneously send multiple data flow, and this needs a separate antenna for each flow.

-More wide frequency range: support 2.4GHz and 5GHz bands or new 6GHz (WiFi 6E) require extra antennas for optimal performance of each frequency.

-**: Multiple antennas help eliminate dead spots in home or office by increasing signal spread and coverage area.

• Cihaz density: As the number of connected devices in homes increases, routers use extra antennas to manage more connections simultaneously.

• Beamforming: Advanced routers use beamforming technology, which can redirect the signal to certain devices, which requires additional antennas.

Indeed, the increase in the number of antennas can be explained completely for technical reasons. But marketing teams also know that these physical visibility affects consumers. When you see more antennas, the device is more powerful. But when making a decision to purchase, it is more important to see only the actual specifications of the router rather than the number of antennas, WiFi standard and user reviews.
