Can AirLive’s Beam Forming Technology Resolve Wi-Fi Dead Spots?
5/25/2012 by: Theo Valich
New product launch are typically exciting. When it comes to networking gear, the launches are usually exciting as watching drying the paint of the wall, but AirLive came up with something new that could shake up the market: a beam forming router.
Typically, wireless routers are all nice and dandy, and they either compete in the number of antenna, or the lack of them (when the chassis is used to store antennas). Recently, we received an interesting release from AirLive, in which the manufacturer claims it managed to sort the dark reception spots by triangulating the devices and focusing the beam towards the location of a connected device.
Instead of dispersing the available power to all of the three antennas, the N450R will utilize its "direction sensing" approach to detect where the devices are located and focus the beam on it. The manufacturer claims that they can reach death spots where the wireless signal did not reach before, including thick walls, multiple floors and so on.
This is an official explanation of the technology:
"Beam forming is a signal processing technique used to control the directionality of the transmission and reception of radio signals. The most effective type of beam forming is dynamic digital beam forming. This type of beam forming uses an advanced, on-chip digital signal processing (DSP) algorithm to gain complete control over Wi-Fi signals.
By creating several independent signal paths to optimally focus radio energy to and from client devices on a per-packet basis, performance is dramatically improved. In the case of a two-stream configuration, this makes it possible to steer the energy of the antenna array in the independent spatial directions associated with both data streams, while simultaneously avoiding interference."
This is quite a bold claim form the manufacturer and we have contacted them over a review sample, to either confirm or deny these claims.
Besides the beam forming tech, this is a typical dual-band 802.11n router capable of outputting 450Mbps through 3T3R. There’s also a Gigabit NAT present and two USB 2.0 ports for NAS. Price was not known at press time.
