But let’s discuss the wireless keyboards in terms of Bluetooth and infrared, assuming that all other factors are equal.

Infrared keyboards are, hands down, much cheaper than the Bluetooth ones. They are relatively easy to set up and they can be used at a fair distance so long as they stay within the line of sight of the infrared connector. The downside is that you can’t take it beyond what the computer can see because it will go out of its line of sight.

While Bluetooth keyboards are more expensive, you don’t have problems with line of sight as well as connectivity in general. You can practically bring your keyboard around at a fair distance without worrying about solid objects that might obstruct the connection between the device and the host computer.

The battle between infrared and Bluetooth keyboards is that of a classic cost-benefit one. Are you willing to pay more for Bluetooth’s connectivity, or would you rather have the cheaper infrared one? This is up to you to decide.

Wireless Keyboards: Infrared vs. Bluetooth

Based on Linux Kernel, Google Android is a special operating system designed for mobile devices that was developed by Google and Open Handset Alliance. Thanks to the Open handset Alliance, this great little mobile OS came with a handful of useful applications that made the Google Android even more popular.

But in order for you to be able to enjoy this great software on your mobile device, you have to make sure you have the following:

• 32 MB RAM

• 32 MB Flash Memory

• 200 MHz processor

Google Android also comes with the Software Development Kit (SDK), a software for developers using Google Android, which requires the following:

• Java Development Kit

• Apache Ant

• Python 2.2

Google Android was developed with the intent of providing a system that is friendly to developers who want to get creative with their mobile devices. As feedback of current users comes in, this little mobile OS just gets better and better every version release.

Google Android System Requirements

In the notification area of Windows, which most people refer to as the System Tray, you should see a small icon of a computer monitor. By hovering your mouse over the icon, you will see a realtime report of your connection status.

If you right click while hovering over the icon, one of your options should be to “repair” the connection. If you select this option, a window will pop-up, and your wireless connection will cycle through the network connection process again, first terminating the existing connection, and then attempting to start it up again.

If you are troubleshooting a network for which you have administrator rights, the next thing to try is to reboot the router. In most cases, this can be accomplished from within your web browser, if the connection is working at all. In other cases, the router may be locked up, in which case you will have to turn it off or unplug it for around 30 seconds, and then turn it back on again. Amazingly, this will repair a large number of simple connection problems.

Rogers and Fido GPRS and WAP settings

Wireless local area networks, or WLANs, provides access to various forms of connection through the 802.11 standards.  In design, the security is available using this method as would be expected from from a wired LAN network.  Once data has transferred from a wireless to the LAN, this holds true, but encryption methods had to be devised to allow secure communication between the end-device and the distribution hub of the network.

To accomplish this, two standards were developed, the WEP, also known as Wireless Equivalent Privacy, and Wi-Fi Protected Access, or WPA.  of the two, WEP is more commonly adhered to, although WPA is gaining in popularity.  WPA integrates an encryption method into basic communications with the host, which establishes a direct, secure link between to points.  This is a major improvement over individual devices negotiating, or users exchanging keys, as it eliminates a vulnerable gap in existing encryptions methods.

If you are adding wireless capabilities to a network, or designing a brand new network around today’s technology, WPA is the most likely route to follow.  It provides greater security and connectivity, and is a welcome complement to the upcoming release of 802.11n, and update to the standard wireless protocol which is due to be finalized late this year.  Wireless devices may also enter the network via VPN, or Virtual Private Networking, which allows remote devices to be accessed just as though they were connected via hard wiring, and this integrates yet another level of security.  VPN generally incorporates the IPSec set of protocols to provide IP layer security.  Most data being transferred into or out of a network is being carefully monitored, and various methods of encryption are used for different purposes.  For overall wireless connectivity, WPA is the best course of action.
