A "3D" processor could make wireless communication more efficient according to scientists at the University of Florida. It could benefit both WiFi and cellular data services. One of the limitations of current WiFi tech is that it uses a "planar ... processor" to handle the wireless signal. Because these processors are (in practical terms) two-dimensional, they can only work with a limited range of wireless frequencies. Expanding the range of frequencies planar processors can handle is only possible by making them wider, a little like increasing capacity on roads. But making the ... (view more)

Samsung has made a battery-less remote control that takes power from Wi-Fi signals. It's proof the concept works, though it's still very questionable if the same approach could work on devices such as phones or laptops. The remote is an update on an ... existing "Eco Remote" model that uses solar power to top up the battery. Although solar is naturally very limited inside a home, a rechargeable battery in a remote only needs very slow, low-power topping up as it uses little energy to operate. Samsung says it then explored a range of wireless charging technologies to add to the solar in a second ... (view more)

Google says it has successfully used beams of light in the air to carry an Internet signal. It says the technology won't work everywhere but could be a useful solution in specific places. Project Taara works on a broadly similar principle to fiber ... optic cables, with pulses of light carrying a signal that translates into the 0s and 1s of computer code. The "Free Speech Optical Communications" system uses a narrow beam of light invisible to the human. It's a similar technology to that which Google used in a previous project to connect balloons in the sky. The new system instead connects ... (view more)

Comcast is to impose a 1.2TB monthly data limit on its broadband customers in all locations across the United States. The move affects 12 states that weren't already under the cap. Customers will be able to get unlimited data, but will have to pay a ... fee of $30 a month above their current charges. Those who don't "upgrade" will face an overage charge of $10 for each 50GB they use, with a maximum overage charge of $100. (Source: stopthecap.com ) The company already had the cap in 27 of the 39 states it served. Many of the remaining 12 covered markets where Comcast had competition with Verizon, ... (view more)

I've tried to settle this amicably but now he's threatening to (among other things) hack into my computer and delete my files. Since then, ... my Internet has been slow and I suspect that my neighbor is stealing my WiFi signal . I have searched all over the Internet on how to stop someone from stealing WiFi , but the solutions are not effective. I am scared to death he may get into my machine and cause havoc. Can you PLEASE help me? I'm desperate for help and you are the ONLY one I trust ... (view more)

Microsoft has blocked users of some security software from updating Windows 10. It's also spotted some problems with specific WiFi drivers. The good news is that although the Windows 10 problems are with the well-known Avast and AVG security tools, ... it only affects older versions. Specifically the problem comes if the software is from version 19.5.4444.567 or earlier. (Source: techradar.com ) Since Avast! also owns AVG, the version number is the same for both engines. Automatic Updates On Hold Microsoft hasn't said exactly what the compatibility problems are, but has put a block on automatic ... (view more)

Users have highlighted two more problems with the latest Windows 10 Update, released September 10, 2019. It's messed up sound for some users, while others can no longer get online. For those keeping track, the problems are with the Windows 10 update ... KB4515384 , which has already given some users a broken Windows search tool and others a mysterious red or orange hue to their screen. Ironically, that update was designed partly to fix problems with a previous update ( KB4512941 ) which broke the Windows Search for some users, and also caused constant high processor demand for others. One of the ... (view more)

The latest Windows 10 update, which is rolling out now, has thrown up at least three highly reported problems for users. The most significant is that some computers are losing WiFi access. The Windows 10 May 2019 update affects some computers which ... have a Qualcomm WiFi adaptor and don't yet have the latest driver for it. A driver is a small piece of software that helps a hardware device or component interact with an operating system. Some users in this situation have suffered what Microsoft is calling an "intermittent loss of WiFi connectivity." It's responded by blocking the update from ... (view more)

Unfortunately my Windows 10 laptop WiFi does not have an 'on / off' switch which ... would disable my WiFi permanently. Instead, I have been using Windows 10 "airplane mode" to disable the WiFi, but this doesn't work 100% of the time because my WiFi seems to activate spontaneously. I am super paranoid about having a WiFi connection because I don't believe there is a 100% secure WiFi, and therefore I don't ever want to use WiFi on my ... (view more)

Light could be the key to solving one of the big problems of faster mobile Internet. But the technology, which uses spotlights to send out signals, has some limited range of uses. The technology developed by pureLiFi works on a simple principle: ... rather than using radio waves to transmit data (as does WiFi), it uses light waves. A demo of the system uses ceiling spotlights which blast out light in a cone shape. To the human eye it looks like an ordinary constant light supply. In fact it's actually flickering at incredibly high speeds to create a pattern. 5G Signals Hurt By Walls A plug-in ' ... (view more)
