Want to know why your cell phone service sucks all the time? Phone companies will tell you: it's bandwidth, man. The wireless spectrum is getting crowded and there's just not enough room. What's needed is a new way to cram more data into the same amount of space, and the solution might be to twist multiple light beams together into a vortex.
Under normal circumstances, I wouldn't use this space to simply describe a new product, in this case two new products — the new Buffalo AirStation WZR-D1800H ($179.99) 802.11ac router and its sibling, the WLI-H4-D1300 wireless media bridge (also $179.99), which went on sale last week. But I'll make an exception for these two products, the first commercially available Wi-Fi 802.11ac gear. Aka "gigabit Wi-Fi," these and other pending 802.11ac gear promises to deliver Wi-Fi transmitted content at between 1.3 and 1.75 Gbps, around twice as fast as today's fastest 802.11n routers. Why the exception? Because these products portend a momentous change in our wireless communications lives. I'll explain this hyperbolic pronouncement — and what a "wireless media bridge" is — after the jump.
Do you have the need for speed? Wi-Fi speed? Who doesn't? Boy, do we have good news for you! A group of Japanese researchers have just broken the record for wireless data transmission in the terahertz band resulting in data transfers that are 20 times faster than standard Wi-Fi.
Trust me, all of your neighbors have already figured out that the password to your Wi-Fi network is the name of your cat, and they're busy pirating movies and software and when the MPAA breaks down the door you're the one who's going to a labor camp in Siberia. Don't let this happen to you, install wallpaper that keeps your Wi-Fi contained.
For the first time, particle physicists have successfully used neutrinos to transmit a message from one place to another. Since neutrinos travel at (or near) the speed of light and can pass through just about anything, neutrino communication could potentially replace wires, Wi-Fi, satellites and everything else as the ultimate method of transmitting data.
For all of us frequent fliers the days of listlessly leafing through that dog-eared copy the inflight-shopping catalog are over. At least on Delta Airlines. The airline just announced consumers will soon have free access to Amazon.com as part of its overall Wi-Fi service.
Photos and photo apps are a part of our everyday life now thanks to our mobile phones. A big downside is that in most cases we never print the photos — they stay in the virtual world. Wouldn't it just be nice to be able to print one out every now and then?
Straddling the border of north central Virginia and southeastern West Virginia is a 13,000-square-mile mountainous region known as the United States National Radio Quiet Zone. To protect the clutch of radio telescopes located within its borders from radio interference, the federal government highly regulates wireless technology, which means no cellphones and few Wi-Fi hotspots. Sleepy towns within this quiet zone might soon be invaded by folks trying to escape the onslaught of wireless technologies. You see, not only are cellphones suspected (emphasis on suspected) of causing cancer, but some scientists are now claiming Wi-Fi should be seen as a health hazard. But there are equally vociferous scientists who say all these Wi-Fi Chicken Littles are foolish fowl. So, is Wi-Fi harmful to you? This is an imponderable on the level of asking if animals have souls, or why we park in a driveway but drive on a parkway, or Coke or Pepsi. Of course, I have all the answers.
A report that came out in October, 2011 showed that the number of wireless devices in the U.S. exceeds the number of humans. It's an incredible fact, but it has a downside — all those gadgets in addition to radio and television signals are gobbling up space on the electromagnetic spectrum
Robert Moses, a man who never learned how to drive, ironically was the greatest road builder in history. From the early 1930s to 1968, Moses built nearly every major highway in and around New York City and Long Island, and all the bridges and tunnels attached thereto (and lots of other stuff). Moses also may have invented the traffic jam. To everyone's shock, a Moses highway designed to alleviate traffic would suddenly fill with it, forcing him to build more highways, which in turn got filled with traffic, forcing him to build more highways, which then got filled with more traffic I bring up Mr. Moses and his crowded highway exploits because of a recent post week on CNN Money, "Sorry, America: Your Wireless Airways Are Full." Welcome to the spectrum crunch reporting party, mainstream media. It seems Moses' self-perpetuating highway expansion cycle is repeating itself on our cellular network highways. Each time our smartphones and tablets become more powerful, we pull more content through the 3G and 4G spectrum, encouraging smartphone makers to make more powerful smartphones, encouraging us we pull more content through the 3G and 4G spectrum Cellular spectrum is finite. We're filling it like a closet with junk — or a new road everyone wants to drive on. But a solution is coming: Wi-Fi to the rescue!
