also uses radio waves, but ones of a shorter range. Infrared, uses, as the name suggests, Infrared waves. Infrared is shorter than radio waves and the names means below (Infra is Latin) red.Wi - Fi technology uses radio waves in set area distance. Wireless network are becoming more and more popular in homes due to how easy it is to install and use. Practically all businesses and coffee shops use them. Some cities are now even offering them free to their communities. Wi Fi is used in Desktop computers, Laptop Computers, and Wi - Fi enabled mobile phones.
Wi Fi is very good because it make life easier, it can be used from any location within range. This even extends to it being able to be used outside their home network and work places like in Cafés and Coffee shops, or any establishment offering free connection, or connection at a very small price. Wi Fi is also very easy to set up. Almost every
home has its own network now. The bad thing about Wi Fi is that if it is not protected with a WPA (Wi Fi Protected Areas) or WEP (Wired Equivalent Privacy or Wireless Encryption Protocol) key, anyone can connect to the network and use it as they wish.Bluetooth has its own advantages in that it uses very little power. Requires less or no setup when compared with Wi Fi. Bluetooth is used in mobile phones, laptops, PCs, printers, digital cameras, and video game consoles. Disadvantages are that the range of bluetooth is even smaller than that of Wi Fi but considering that it was made for Personal Area Network, the range is sufficient. People can also connect to a bluetooth device without them knowing and without their consent. This is why bluetooth is not as popular as Wi Fi.
Infrared is used mainly by the military for target acquiring, spying and monitoring, orientating and trailing. Uses that are not militarily orientated include thermionic skillfulness investigation, remote temperature detection, short - ranged wireless communication, spectrometry, and
predicting the weather. Infrared uranology puts to use sensor - panoplied telescopes to perforate dusty areas of outer space, like molecular clouds for example; they are used to detect cool objects like the planets, and to see extremely red - shifted entities from the early days of the universe. Disadvantages of Infrared are that because of the short ranges and the fact that the signal has to be directly in front of the Infrared port, so therefore, the signal is easily disrupted and the signal can be interfered with and lost.
