Technology built the most modern routers, the beamforming promises to improve data transmission and the range of the Wi-Fi network. Learn how it works and see if it is worth buying a router with technology.
Internet ‘infinite’ and safe: device delivers signal in an area of up to 4 km
Before understanding the beamforming is necessary to detail how routers work. The omni-directional antennas of common routers work radiating Wi-Fi signal equally in all directions. In practice, this means all devices that are in the sign of range will be able to exchange information with the router.
How many concurrent connections a wireless router? Check out the TechTudo Forum.
The beamforming acts in a different way, focusing the signal in a specific direction, where one or more devices are connected. Thus, the transmission between smartphone and the router, for example, have a better quality, less susceptible to interference and extended range.
The TP-Link explains beamforming with an analogy between a lamp and a laser. The lamp would be the common router, which illuminates in all directions; and the laser, the router with beamforming which concentrates the signal for which the devices are connected.
Compatibility
beamforming emerged as part of the 802.11n protocol. However, although promising, the technology did not become popular, especially for not having a pattern. This made each manufacturer created a different specification and did not guarantee compatibility with some devices, same as they ‘theoretically’ had beamforming.
This was enhanced in 802.11ac protocol. Not all routers have the AC beamforming, but those who have should follow the mandatory requirements defined by the IEEE. This ensures compatibility with devices that have the technology.
At first, to get the maximum beamforming capacity is necessary that the receiving device (smartphone, TV, notebook etc.) is also compatible – it is worth remembering that even without being compliant they usually connect to the network. So before investing in a router with technology, it’s worth doing a search on the site of the manufacturer of gadgets that will be used.
Some manufacturers have developed their own technologies to ensure that even a device to specified with beamforming use the technology, as is the case with Beamforming +, Netgear and SmartBeam, from D-Link.
