Technology has given spies the ultimate weapon in listening devices: the spy mobile phone. The great thing about these cell phone bugs is that they are so ordinary looking and function normally. When you are listening in, you do not look suspicious because just about everyone now has a mobile phone. Their very presence in every aspect of society is a plus. There is virtually no place that your spy mobile phone cannot go, and therefore it is the ultimate in infiltration.

The new generation of spy mobile phone allows you to listen in on conversations that are being had on the phone, as well as listening to conversations in the area of the phone when it is not actively in use. The phone is the ultimate in surveillance technology. You can send it off with your teenager to make sure that he or she is not engaging in inappropriate activities, or you can give it to your significant other and make sure she or he is not cheating on you. It is an excellent way to learn all that you need to know, and never be suspected of listening in.

You give the spy mobile phone to whomever it is that you need to listen in on (heck, get them for the whole family!). Each phone is programmed with two numbers. The first is the regular phone number that anyone can call. The second is a secret number that you choose. When you call the secret number, the phone activates without giving any sign to the person who has it. It is quietly active (even if it is not in use) allowing you to listen. If you dial in and the person is using the phone, you have instant access to both ends of the conversation. If you dial in and the phone is not in use, you can hear everything that is going on in the room.

Not only can you dial in at will, but it is also possible with the spy mobile phone to program the phone to call you. It calls you when the person is calling someone else or even when the person receives an incoming call. There is no reason for you to miss a single communication when you have the ultimate spy mobile phone.

Wifi known as Wireless Fidelity allows a user to connect to the internet without using network cabling. Whether it’s from your bedroom, couch, indoors or outdoors data can be sent and received within the range of a wireless base station. Wifi uses 802.11a or 802.11b technologies to provide a very reliable connection that is also fast and secure.

Wifi is available to every type of internet user and allows multiple users to connect to each other, other devices and the internet. However, your connecting device will need to have a Wifi certified card (PC Card or PCMCIA card) and it will connect to other certified products such as a base station or access point. It also saves on the cost and distance limitations of using cables, not to mention the unsightly look of running cables throughout an area.

These networks are very useful in the business and sales industry as they allow salespeople and travelers to connect to the network with ease and not be confined to one location to access applications such as email and databases. They allow business networks to easily expand and grow making a Wifi network a very useful technology in the business world. Businesses no longer need to abandon current network infrastructures and start over, they can simply use this wireless technology to easily change the network and allow for rapid growth.

Wifi networks work at the 2.4 or 5 GHz bands and possible speeds of 11 or 54 Mbps. Their speeds are very comparable to 10baseT networks and allow for easy network access. A Wifi network is essentially plug and play as you can turn on a certified device and connect to the wireless network providing you have the proper authentication and security credentials.

Wifi networks have security in the form of WEP (Wired Equivalent Protocol) that can provide the same level of security as that of a wired LAN. Wireless networks that are transmitted over radio waves are more susceptible to security problems, but WEP aims to provide security by encrypting the data sent over the radio waves.

In this article we’re going to begin to define what wifi is and just how it works.

Relatively speaking, wifi is a new technology, created within the last couple of years at the time of this writing. However, the basis on which is created is not really new. Wifi is short for wireless fidelity as applied to connecting multiple computers. Or in other words, wireless networking.

The reason this is not really new is because we’ve had wireless forms of communication for some time now. One needs to look no further than ones own hi fidelity stereo system. The signal from the ration station transceiver travels wireless through the air until it reaches the antenna connected to your radio. This technology has been around for ages. But as applied to computers, yes, this is something very new.

So, how does wireless networking work?

The 802.11 standard, on which networks are based, defines two modes which are infrastructure mode and ad hoc mode. With infrastructure mode, the wireless network is composed of at least one access point which is connected to the wired network infrastructure which includes a set of wireless end stations. This particular configuration is called a Basic Service Set or BSS. An extended service set, or ESS, is a set of multiple BSS sets which form a single subnetwork. Because most WLANs require access to a wired LAN for services such as file servers, printers and Internet links, they usually operate in infrastructure mode.

The difference between Ad Hoc mode and Infrastructure mode is that Ad Hoc mode is just a set of 802.11 wireless stations that communicate directly with each other without using an access point or any connection to a network that is wired. This mode is great for quickly and easily setting up a wireless network where a wireless infrastructure doesn’t exist or is simply not needed for services. Some places where this would be true are hotel rooms, convention centers and airports or any place where wired networks are forbidden.

While connected to a wireless network, you can do most basic things that are not too intensive such as check email, browse the Internet, connect to conferences, access your home directory, use programs such a network word processor and use printing services. You should not use wireless networks for streaming audio or video, downloading anything that is large or viewing web sites that are intense in graphics.

Even though wireless networks are nice to look at you will still get the best performance and highest speeds from wired networks. Generally speaking, a wireless connection works the same way as an Ethernet connection. The speed of a wireless network is about 11 megabits per second. The problem is that with a wireless network you have to share the bandwidth with all the users connected to the wireless network in a given network. This is what slows the network down and makes intensive operations difficult to perform. It is because of this that wireless networks will never be as fast as a wired Ethernet network.

In the year 1980, investigation agencies ushered in the age of DNA testing that permitted investigators to perform astonishing feats for identifying people. The technological advancement of the present day allows a person to be differentiated from others with the examination of a single hair root. DNA profiles are now widely used in resolving issues of parentage, not only in human beings but also in animals.

DNA is the material that governs inheritance of eye color, hair color, stature, bone density and other characteristics in humans and animals. DNA is a long narrow string-like object that can be normally packed into a space roughly equaling to a cube 1/millionth of an inch on a side. A strand of DNA contains tiny building blocks and is basically classified into four categories i.e. A, T, G, and C, by scientists across the world.

DNA testing has its own advantages over serological methods such as blood typing and HLA analysis. A standard DNA typing can be conducted with a few hair roots, and does not require injecting syringes in the body. In contrast to proteins, DNA can be amplified by using the polymerase chain reaction method. By this method, even smaller sample sizes are adequate for testing. In comparison to proteins, DNA is considered to be resistant to degradation by common environmental insults. These tests can be performed even when the samples have been exposed to detergents, acids, gasoline, salt or bacterial contamination.

DNA typing can be performed by demonstrating differences in length of specific DNA sequences. The process can be performed by digestion of DNA with restriction enzyme(s), followed by Southern blot hybridization using a probe specific for the polymorphic site. Other methods include single-locus DNA fingerprinting, in which polymorphism at a single locus is characterized, usually through the use of a specific probe or specific PCR primers. Multilocus DNA fingerprinting is another method by which polymorphism at multiple loci is simultaneously identified. The method is either performed by application of a mixture of single locus probes or application of a single probe that identifies multiple similar sequence polymorphisms.

Although scientists believe that there cannot be any method by which identifications can be related so strongly other than the DNA test, there have been some scientifically legitimate criticisms based on concerns about allele frequencies in certain populations. The concerns raised stated that the chances of a random match may be higher than stated, because the database used for identifying the inheritance could be inappropriate for the subpopulation of people containing the suspect.

For years, one of the most worrying problems with wireless broadband internet access was the issue of keeping data secure during the split second of transfer.

If one does not take the proper security precautions, a clever hacker could intercept the signal to steal passwords or even financial information.

Fortunately, WiFi security has seen much notable advancement in the past few years. Encryption technology has become more and more sophisticated, and is now readily available in most devices.

Some of the most common security encryption standards are Wired Equivalency Privacy (WEP) and WiFi Protected Access (WPA).
