Who says technology is pulling us apart?  Researchers at Queen’s University Belfast are developing a new type of wireless network that’s all about bringing people together.  You see, with body-to-body networks, the cellphone towers are people (to borrow a turn of phrase from the 1973 sci-fi film Soylent Green). Now don’t worry: body-to-body networks (or BBNs, as the cool kids call them) don’t involve radiating your body with radio frequencies.  Instead, a person would simply have to have a sensor worn somewhere on their body, or even embedded inside their phone.  These sensors would communicate with others within range to create an ad hoc network, eliminating the need for massive cellphone towers. Which is good since, despite their size, the towers we have now still aren’t enough.  Big cities often face a backlog of users trying to send data through only a few towers, and the costs of maintaining them are often exorbitant.  These towers would also need to be upgraded to keep up with 4G technologies.  Luckily, the BBNs now being researched would work best in the areas most in need of them: crowded cities with lots of people trying to send lots of data.  The closeness of the sensors would allow users to send data at lower power outputs, which would make batteries last for a longer time between charges. It certainly sounds tempting.  What obstacles does this new technology face?  First, it’s still in the research stages, so there’s no telling when this technology would be publicly available, and what it would cost.  Second, it’ll take some fancy marketing to overcome the fears of those worried about cellphone radiation.  However, a 2007 assessment by the European Commission Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) concluded that “exposure to RF fields is unlikely to lead to an increase in cancer in humans.”  One concern raised by Kelly Hodgkins of IntoMobile.com is the possibility of someone writing an app to redirect information to a malicious server.  Whether this would be a possibility or not remains to be seen. Previous technologies are still being considered, such as a change in material for metal antennas.  Researcher at NC State in 2009 were working on a “shape-shifting antenna” that could be bent and stretched and still return to its starting shape.  The material consists of a liquid metal alloy injected into an elastic casing, such as siliconethe casing material differs based on the desired qualities.  In addition, there are other applications for this kind of antenna, Direct TV, based on the fact that a change in frequency would accompany any change in shape.  This could be used in bridges and ships to monitor damages and alert engineers before tragedy hit.

If you own a smartphone, tablet or laptop that you enjoy using in public areas for Wi-Fi connections, you are putting yourself at risk. Many people enjoy visiting their local coffee house, book store, public library or other institution to use their wireless devices while out and on the go. However, it is not always the wisest thing to do because there is always a risk to your device’s security.

When you rely on public Wi-Fi to connect your laptop, smartphone or tablet to the Internet, you are putting yourself at risk because so many others are sharing the Read the rest of this entry »

Even before the future was really the future, back in the 80s when we had things like Back to the Future, we envisioned technological metropolises where people could connect with the world at the press of a button from almost anywhere. Today, scientists would call that “wireless internet” and our understanding of the technology and how to implement it has really advanced in leaps and bounds. Before it was 3G, but now something called 4G has really taken the center stage when it comes to wireless internet technologies.

Wireless high speed internet, clear 4g or just simply 4G – whatever you want to call it, this new wireless internet has really changed the game. When it was initially unveiled, the public was taken by storm with the promises of clear and clean wireless internet access from almost anywhere, hot spots the size of entire cities and none of that network slowdown during peak hours. Much remains to be seen about the future of 4G, but given what the world has already seen in terms of usability and utter ease it is pretty safe to assume that the future, at least of wireless internet, is happening right now. All around us – in our homes and in our lives.

In a day and age when technology is really booming, wireless audio speakers are becoming more and more common. It used to be thought that speakers would always be wired and that was the only way that it would work. However, now with bluetooth, WiFi, infared and other technologies, the opportunity to create wireless speakers has really come to the fore. People, in general, are also getting sick of wires and all the clutter that they bring. People want their homes to be nice and neat, so they want speakers they can place around the house in a Read the rest of this entry »

Your company-s network password is a vital part of business security, and one with little control. While your IT department can require you to use letters, numbers or set a minimum length, they can-t dictate what the password will be. In today-s wireless world, network security is crucial to keeping your business moving forward, and everyone at your company must help.

With a minimum amount of equipment, a hacker can sit in your lobby or just outside your office building and attempt to access your network. When you or other employees use simple passwords, you make Read the rest of this entry »

The people who made wireless internet available should be given a huge pat on the back. Connecting to the web is easier than ever, and with the ease of being able to take the web with you wherever you go information availability is only limited by the users themselves. There are commercial wireless networks that cover large ranges allowing people to connect with their computers on the go. Mobile devices come with data plans, making the net hand held, and netbooks continue to shrink for ease of travel. Wireless was limited to very Read the rest of this entry »

If you’re planning to purchase a wireless router, check the few steps mentioned below to select a suitable one for your needs. The decision can be really difficult one as there are so many choices out there. A wireless router is used for routing the network traffic between your internal network and internet.

Check the wireless standard you’d need

There are several wireless routers that support various wireless standards, like 802.11g, 802.11b and 802.11a, so which of these standards should you use?

The most mature and popular standard is 802.11g and is best Read the rest of this entry »

In the world of high tech, security is the new watchword. Every day, our personal data is under assault from malicious individuals. We see everything from unwanted advertising to identity theft. Because of this, it is more important than ever for everyone to learn some of the basics about network stability.Wireless standards are a series of encoding and transmission designations for wireless communication. Each hardware configuration supports specific wireless standards. To detect and change yours, use this guide. There are also wireless standards for cell phones and bluetooth. Here is a quick list of many common standards. It is not essential to memorize the specific designation for each standard. Instead, it is best to learn from the ground up. The first thing to understand is transmission rate. This is a measure of how much data can be sent over a wireless network at any given time. For most household applications, 11mbps (megabytes per second) is more than enough. For business applications or situations with multiple heavy traffic computers accessing the same network, it might be wise to look for a router that uses a higher mbps standard. Another basic element to note is the GHz rating for the wireless standard. This is essentially a measure of how far the signal will travel. The lower the GHz rating, the farther the signal will travel and the more easily it will pass through walls.Another important consideration is the encryption methods supported by each wireless standard. WPA2 is recognized as the most common and universally utilized wireless security protocol. This is usually sufficient for limiting access to a home network. There are other transmission security encryption methods which might be better suited to your purposes, however. Make sure the encryption you wish to use is supported by your wireless standard.
