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!
Having 40 watts of power pumping out of an outdoor speaker means plenty of volume: limit the chance you'll hear yourself think and increase the chance your uninvited neighbors will call the cops — all at the same time! This speaker also knows a neat trick beyond that, too
Got a gadget you wish had built-in Wi-Fi? Take a peek at this Kickstarter project called CloudFTP, from an outfit called Sanho. You connect this little box to whatever via a USB connection, and you and anyone else can access the connected device's contents.
Well, this is a little unsettling: it turns out that Wi-Fi signals are slightly affected by people breathing, and with the right tech someone could pinpoint where you are in a room from afar using just Wi-Fi.
Having in-flight Wi-Fi is a godsend, but it's not exactly what most would call fast. It's acceptable for light browsing, but not for streaming HD videos. Gogo says its in-flight Wi-Fi will be getting a major 4X boost in speed by early next year.
If you want to get live performance data from a car traveling faster than the speed of sound, you're going to need some pretty speedy Wi-Fi. Wi-Fi on a moving airliner is pretty impressive, but that's nothing compared to the folks at North American Eagle who have applied to the FCC for an experimental radio license for the 800-mph car.
Tired of your Wi-Fi cutting out every time you take your laptop into the bathroom with you? IEEE (also known as the Institute of electronics geeks) has just released a new, official standard for 802.22 Wi-Fi, and this bad boy can cover 12,000 square miles with just one single base station.
Everything is always 100% better after a nice little nap, and Wi-Fi is no exception. By allowing smartphones to take sub-second naps while waiting to transfer data, it's possible to double battery life with just a clever piece of software.
