iFi communication is very similar to the radios we see in phones and televisions. They can transmit and receive waves, and they can convert ones and zeros into radio waves and convert radio waves back into ones and zeros. However, WiFi radios have some distinguishable differences from other radios. They transmit at frequencies of 2.4 GHz or 5 GHz. Keep in mind that the frequency is considerably higher than the frequencies used for cell phones, for example, and for this reason it can transfer much more data at higher speeds. Data is sent digitally in packets. Each packet is identified with the MAC address and IP address of the individual device, which are unique. This way nothing gets confused. Interestingly, data is also sent in the form of packets when transferred over Ethernet cables. One aspect of this technology is a "hotspot". A WiFi hotspot is what we call an area with an accessible wireless network. The term, however, is often used to refer to wireless networks in public settings such as restaurants and shopping malls. While some are free, many require usage fees. They may be charged based on data used or network connection time. It's a huge convenience but sometimes it will come at a price; Hotels are also known to charge a significant amount for internet connection. With most smartphones you can even create your own WiFi hotspot. This is possible because, as explained above, WiFi radios are a two-way system capable of both transmitting and receiving. This will convert your phones receiving LTE or 3G data packets to WiFi signal transmission. A wireless router is what uses an antenna to send signals to wireless devices and a cable to send signals to the Internet. Five...... middle of paper ...... there are multiple walls that prevent two devices with Bluetooth from communicating and usually that won't be a problem. One disadvantage worth mentioning though would be the lack of security. Encryption measures have been put in place, but it's hard to ignore that this is a fairly automatic connection format. That's the concept of the technology, and there aren't many ways around it. The ease of connectivity is partly why the product is so successful. This unfortunately allows people to share unwanted information if they want to (e.g. hackers). “Car Whisperer is software that allows hackers to send and receive audio from a Bluetooth-enabled car stereo. Like a cybersecurity flaw, these vulnerabilities are an inevitable result of technological innovation, and device manufacturers are releasing firmware updates that address new issues as they arise.”
