Today's Wifi vs 802.11ac Beamforming Technology


Beamforming

All about beamforming, the faster Wi-Fi you didn't know you needed

Beamforming is one of those concepts that seem so simple that you wonder why no one thought of it before. Instead of broadcasting a signal to a wide area, hoping to reach your target, why not concentrate the signal and aim it directly at the target?
Sometimes the simplest concepts are the most difficult to execute, especially at retail price points. Fortunately, beamforming is finally becoming a common feature in 802.11ac Wi-Fi routers (at least at the high end). Here’s how it works.
First, a bit of background: Beamforming was actually an optional feature of the older 802.11n standard, but the IEEE (the international body that establishes these standards) didn’t spell out how exactly it was to be implemented. The router you bought might have used one technique, but if the Wi-Fi adapter in your laptop used a different implementation, beamforming wouldn’t work.
Some vendors developed pre-paired 802.11n kits (with Netgear’s WNHDB3004 Wireless Home Theater Kit being one of the best examples), but these tended to be expensive, and they never had much of an impact on the market.
BeamformingNETGEAR
Beamforming concentrates the signals exchanged between a Wi-Fi router and the clients it's paired with.
The IEEE didn’t make the same mistake with the 802.11ac standard that’s in today’s high-end devices. Companies building 802.11ac products don’t have to implement beamforming, but if they do, they must do so in a prescribed fashion. This ensures that every company’s products will work together. If one device (such as the router) supports beamforming, but the other (such as the Wi-Fi adapter in your router) doesn’t, they’ll still work together. They just won’t take advantage of the technology.
Beamforming can help improve wireless bandwidth utilization, and it can increase a wireless network’s range. This, in turn, can improve video streaming, voice quality, and other bandwidth- and latency-sensitive transmissions.
Beamforming is made possible by transmitters and receivers that use MIMO (multiple-input, multiple-output) technology: Data is sent and received using multiple antennas to increase throughput and range. MIMO was first introduced with the 802.11n standard, and it remains an important feature of the 802.11ac standard.

How beamforming works

Wireless routers (or access points) and wireless adapters that don’t support beamforming broadcast data pretty much equally in all directions. For a mental picture, think of a lamp without a shade as the wireless router: The bulb (transmitter) radiates light (data) in all directions.
Devices that support beamforming focus their signals toward each client, concentrating the data transmission so that more data reaches the targeted device instead of radiating out into the atmosphere. Think of putting a shade on the lamp (the wireless router) to reduce the amount of light (data) radiating in all directions. Now poke holes in the shade, so that concentrated beams of light travel to defined locations (your Wi-Fi clients) in the room.
Linksys EA6900 Wi-Fi router
The Linksys EA6900 is one of several 802.11ac routers on the market that support beamforming today.
If the Wi-Fi client also supports beamforming, the router and client can exchange information about their respective locations in order to determine the optimal signal path. Any device that beamforms its signals is called a beamformer, and any device that receives beamformed signals is called a beamformee.

Netgear's Beamforming+

As mentioned earlier, beamforming support is an optional element of the 802.11ac standard, and any vendor offering it must support a specific technique. But the vendor can also offer other types of beamforming in addition to that standard technique.
Netgear’s Beamforming+ is a superset of the beamforming technique defined in the 802.11ac standard, so it’s interoperable with any other 802.11ac device that also supports beamforming. But Beamforming+ does not require the client device to support beamforming, so you could see range and throughput improvements by pairing one of Netgear’s routers (specifically, Netgear’s model R6300, R6200, and R6250) with any5GHz Wi-Fi device (Netgear’s R7000 Nighthawk router also supports beamforming on its 2.4GHz network).
Netgear is not the only router manufacturer to support beamforming, of course. It’s becoming a common feature on all of the higher-end Wi-Fi routers and access points. If you’re in the market and want a router that supports beamforming, check the router’s specs on the box or at the vendor’s website. Here are three other routers you might consider: the Linksys EA6900, the D-Link DIR-868L, and the Trendnet TEW-812DRU

Making car accidents a thing of the past

New Technology Designed to Keep Drivers From Getting Into Car Accidents

safedrive-articleTechnology has been making driving much safer for decades. From seat belts to anti-lock brakes to airbags, today’s cars are safer than ever.
But one thing technology hasn’t addressed is the prevention of accidents themselves – until now. Because it appears that the technology to prevent accidents not only has been invented, but it’s become readily available as well.

Making car accidents a thing of the past

This technology uses radar, and is designed to address the leading cause of car accidents: driver inattentiveness (otherwise known as “distracted driving”). In fact, according to a study released by the National Highway Traffic Safety Administration (NHTSA) and the Virginia Tech Transportation Institute (VTTI), 80% of crashes and 65% of near-crashes involve some form of driver distraction. And the distraction typically occurred within three seconds before the vehicle crash!
The reasons for distracted driving are varied, and are universal (meaning we all fall victim to them from time to time.) These can include:
  • Driving while tired
  • Following too closely
  • Not noticing a car in your blind spot, or perhaps even a pedestrian or bicycle
  • Being distracted by children, friends, the radio, or pets
  • Eating / drinking in the car
  • Talking or texting while driving
  • Drifting out of a lane
  • Merging too quickly
We all experience some of these from time to time. And any one of them could have life-changing repercussions. Even if you survive an accident, if you injure or kill somebody else, your life will never be the same.
Radar technology addresses every one of these issues, because it warns you when you are drifting out of your lane, when you are too close to another object or car, and so on. It’s almost like a shield around your car that alerts you to anything wrong within its vicinity, and prevents most accidents by completely eliminating the dangers posed by distracted driving. You could say this new technology will “undistract” you.

Radar Safety for Everyone

This radar technology has been cropping up in high end luxury cars. But now it’s become available to everyone. A company called SafeDrive Systems has released a radar system that is easily affordable by anyone, and can make distracted driving accidents a thing of the past. They have free information available so you can see for yourself how this can help you, your children, and/or your elderly parents avoid accidents, now and forever.

Flying squid outruns Usain Bolt

Flying squid outruns Usain Bolt

Jamaican sprinter Usain Bolt can brag about being the fastest man alive. However, he certainly cannot be as proud knowing that a species of oceanic squid can move through the air at faster speeds than him.
The Neon Flying Squid propels itself out of the ocean by shooting off water at high pressure, then opens its fins to glide at up to 11 metres per second and manages to fly for a distance of approximately 30 metres.
Olympic Gold medallist Usain Bolt averaged just 10.31 metres a second when he won at the London Games last year.
The reason the Neon Flying Squid uses its flying advantage is to avoid predators, according to Jun Yamamoto of Hokkaido University. He and his team of researchers published their study about Neon Flying Squids in the German science magazine Marine Biology this week.
“There were witnesses who said squid were seen flying. However, no-one had clarified how they actually do it. We have proved that it is true,” Yamamoto stated.
He and his team were tracking a shoal of around 100 squids in the northwest Pacific, around 600 kilometres east of Tokyo, in July 2011.
When the researchers’ boat approached, the 20-centimetre creatures launched themselves into the air with a powerful jet of water that shot out from their stems. “The fins and the web between the arms create aerodynamic lift and keep the squid stable on its flight arc,” Yamamoto added.
The squids remain in the air for about three seconds and therefore travel for 30 metres, in what Yamamoto described as a unique defence strategy to escape being eaten.

UFO disrupts flights at Bremen airport in Germany

smaller_textlarger_text
Flights were disrupted when a UFO appeared on radars at a German airport, police have said.
The unidentified aircraft cancelled one flight, diverted another and caused delays at Bremen airport.
The airport said the UFO showed up on its radar several times between 16h30 and 21h30 local time.
Police, who scrambled a helicopter to investigate, admit they still don’t know what the object was.
The incident cancelled a flight from Frankfurt, while another from Munich was diverted to Hanover.
A similar incident in Saxony on Sunday turned out to be a remote-controlled model airship.
