Wi Fi technology

What is Wi Fi?

A way to get Internet access, the term Wi Fi is a play upon the decades-old term HiFi that describes the type of output generated by quality musical hardware, Wi Fi stands for Wireless Fidelity and is used to define any of the wireless technology in the IEEE 802.11 specification - including (but not necessarily limited to) the wireless protocols 802.11a, 802.11b, and 802.11g. The Wi-Fi Alliance is the body responsible for promoting the term and its association with various wireless technology standards.

What is a Wi Fi Hotspot?

A Wi Fi hotspot is defined as any location in which 802.11 (wireless) technology both exists and is available for use to consumers. In some cases the wireless access is free, and in others, wireless carriers charge for Wi Fi usage. Generally, the most common usage of Wi Fi technology is for laptop users to gain Internet access in locations such as airports, coffee shops, and so on, where Wi Fi technology can be used to help consumers in their pursuit of work-based or recreational Internet usage.

How Can I Use Wi Fi?

You must be using a computer or PDA that has Wi Fi connectivity already working. Most portable computers can add Wi Fi using an adapter that plugs into a PC card slot or USB port.

Will I need to have an account with a Wi Fi service provider?

Generally, no. You should be able to sign up with the provider at the location. Many providers will display instructions when browser software opens on a WiFi-enabled computer. If you don't have an account, simply start your computer and make sure your Wi Fi card is plugged on. Then, open a browser.

Is Wi Fi the same as Bluetooth?

No. While both are wireless technology terms, Bluetooth technology lives under the IEEE protocol 802.15.1, while Wi Fi falls under the 802.11 specification. What this means for consumers is that appliances using Wi Fi technology and those using Bluetooth technology are not interoperable. Bluetooth and Wi Fi are different in several ways, and are not necessarily in competition. Wi Fi technology boasts faster data transfer speeds and range, making it a good replacement for Ethernet (802.3) systems, while Bluetooth requires less power and is therefore more prominent in small appliances, such as PDAs.

Copying XBOX Games

There really is no shortcut to copying XBOX games. In fact, this is a mightily complicated process and has stumped some really techie people. This is evident with the prevalence of the question on copying XBOX games in Internet message boards and tech chat rooms. But why does one need to be going about there and copying XBOX games? Is this not legal? If you have an XBOX and you have purchased original games to play on it, chances are you must have ran through a huge chunk of your savings. Original games are very expensive and because CDs are not exactly immortal, you can eventually wear out a game especially if you use it every minute of the day. To give value to consumers, most countries allow original CD buyers to make back-up copies of their XBOX games in case their original got damaged or got lost provided that they are aware of the law against pirated software and that they actually own an original cd and are only copying XBOX games for their personal use only. While it is relatively easy to do the copying of XBOX games, the same cannot be said in actually using the XBOX games that you have copied. Most software contain an encryption that must be met when inserted in an XBOX. Copying an XBOX game, however, does not copy this encryption. This is a protection system that most XBOX consoles have as protection against flagrant copying of XBOX games. To be able to run XBOX games that you have copied, you need to modify your XBOX. This can be a daunting task especially to beginners who are afraid of destroying their XBOXes with their tinkering. According to most tech experts, there are a lot of ways to modifying your XBOX in order to accommodate the practice of copying of XBOX games. Some are quite complicated and only a tech expert could do while other ways can be expensive but easy. One is to buy and install a MOD-chip. This will allow your console to play XBOX games that you have copied as well as play imported games from other countries with perfect sound and video with no problem at all. While it may seem that all you have to do is purchase a MOD-Chip and then voila, you have another think coming. There are actually a lot of things that you should consider when buying a MOD-Chip. Most recommend the Divineo Modchips, which are purported to be really reliable. Some of the popular brands are the Xecuter 2 and 3, Xenium, SmartXX, X-bit, Alladin, Chameleon and Xchip. Another way in copying and using XBOX games is to change the BIOS of the XBOX so that it will no longer read the requirements of the digitally-signed software. This is basically reprogramming the whole BIOS. You might also consider purchasing a bigger hard drive and just save all your games inside the XBOX. This way, you already have copy of your favorite games inside and would no longer need to swap CDs. The third way is to do the game swapping technique, wherein you will first boot the original CD and then swap the copy once it has already booted up. This might be very complicated and will not actually serve your purpose in copying your XBOX games… that is to preserve your original CDs.

GPS Security Functionality

One of the most common uses of Global Positioning System (GPS) technology, by businesses and consumers alike, is to ensure security from theft, as well as human safety.
Using a GPS tracking system (

A prime example of the usefulness of GPS technology for security purposes is its abilities in the fight against vehicle theft. If you car or truck were stolen, and it had a GPS vehicle tracking (
http://www.gpsdevices.info/gps-vehicle-tracking.php ) system installed, then you would be able to pinpoint the exact location of the vehicle, and see its exact coordinates on a map. You could then turn this information over to the police, allowing them to retrieve the stolen vehicle, and apprehend those responsible for the theft.
GPS technology can also be instrumental in ensuring basic human safety. This is especially true with children, as every parent’s worst fear is their child getting lost or kidnapped. Fortunately, with the help of a child GPS (
http://www.gpsdevices.info/child-gps.php ) tracking device, you can always know the exact location of your child. In the event of a kidnapping, you would be able to determine the exact location of the kidnapper and notify police and other emergency authorities of this information.
All in all, there is little doubt that GPS can be an excellent way to fight crime, and ensure the safety of your belongings and of your family.

Test Fidelity with a Spy Phone

Are you worried that you partner may be cheating on you? With a spy phone it is fairly easy to find out. In today’s world, nearly everyone has his or her own cell phone.

This means that it is easier than ever for significant others to cheat on their partners. No worries about the wrong person answering the phone. With a personal cell phone, you know you are the only person to answer. Plus, partners keep their own phones with them, so there is little chance of someone invading the phone book and seeing suspicious activity. A spy phone, however, will cut right through all this.
The latest spy phone is one that you give to your subject. The person then uses it just like a regular cell phone. They can make and receive calls, enter numbers into a phone book, and do all of the things that one would expect from a cell phone. The major difference is that you have access to communication through the phone. You can even listen to communication that takes place around the phone.
You spy phone comes equipped with two numbers. The first is a regular number. Anyone can call this number and reach your partner. The second number is a secret number that you program into the phone prior to giving it to your partner. Whenever you dial the number, you have access to hear whatever is going on around the phone. If your partner is on the phone, you get to listen in to both ends of the conversation. If your significant other is not on the phone, a microphone that picks up everything in the vicinity of the spy phone is silently activated so that you can hear what is going on in the room.
A spy phone is the perfect surveillance device. You can give it to your partner as part of your new cell plan, and she or he wouldn’t suspect a thing. It goes everywhere with the person, so it is a portable bug that the person does not know he or she is carrying. Plus, whether arranging a clandestine meeting over the phone or listening to a conversation during a secret tryst, you can gather the evidence you need, even if your partner is not actively using the spy phone.
