The development of Wireless technology owes it all to Michael Faraday – for discovering the principle of electromagnetic induction, to James Maxwell – for the Maxwell’s equations and to Guglielmo Marconi – for transmitting a wireless signal over one and a half miles. The sole purpose of Wi-Fi technology is wireless communication, through which information can be transferred between two or more points that are not connected by electrical conductors.Wireless technologies were in use since the advent of radios, which use electromagnetic transmissions. Eventually, consumer electronics manufacturers started thinking about the possibilities of automating domestic microcontroller based devices. Timely and reliable relay of sensor data and controller commands were soon achieved, which led to the discovery of Wireless communications that we see everywhere now.HistoryWith the radios being used for wireless communications in the World war era, scientists and inventors started focusing on means to developing wireless phones. The radio soon became available for consumers and by mid 1980s, wireless phones or mobile phones started to appear. In the late 1990s, mobile phones gained huge prominence with over 50 million users worldwide. Then the concept of wireless internet and its possibilities were taken into account. Eventually, the wireless internet technology came into existence. This gave a boost to the growth of wireless technology, which comes in many forms at present.Applications of Wireless TechnologyThe rapid progress of wireless technology led to the invention of mobile phones which uses radio waves to enable communication from different locations around the world. The application of wireless tech now ranges from wireless data communications in various fields including medicine, military etc to wireless energy transfers and wireless interface of computer peripherals. Point to point, point to multipoint, broadcasting etc are all possible and easy now with the use of wireless.The most widely used Wi-Fi tech is the Bluetooth, which uses short wavelength radio transmissions to connect and communicate with other compatible electronic devices. This technology has grown to a phase where wireless keyboards, mouse and other peripherals can be connected to a computer. Wireless technologies are used:· While traveling· In Hotels· In Business· In Mobile and voice communication· In Home networking· In Navigation systems· In Video game consoles· In quality control systemsThe greatest benefit of Wireless like Wi-Fi is the portability. For distances between devices where cabling isn’t an option, technologies like Wi-Fi can be used. Wi-fi communications can also provide as a backup communications link in case of network failures. One can even use wireless technologies to use data services even if he’s stuck in the middle of the ocean. However, Wireless still have slower response times compared to wired communications and interfaces. But this gap is getting narrower with each passing year.Progress of Wireless technologyWireless data communications now come in technologies namely Wi-Fi (a wireless local area network), cellular data services such as GPRS, EDGE and 3G, and mobile satellite communications. Point-to-point communication was a big deal decades ago. But now, point-to-multipoint and wireless data streaming to multiple wirelessly connected devices are possible. Personal network of computers can now be created using Wi-Fi, which also allows data services to be shared by multiple systems connected to the network.Wireless technologies with faster speeds at 5 ghz and transmission capabilities were quite expensive when they were invented. But now, almost all mobile handsets and mini computers come with technologies like Wi-Fi and Bluetooth, although with variable data transfer speeds. Wireless have grown to such a level, where even mobile handsets can act as Wi-Fi hotspots, enabling other handsets or computers connected to a particular Wi-Fi hotspot enabled handset, can share cellular data services and other information. Streaming audio and video data wirelessly from the cell phone to a TV or computer is a walk in the park now.Wireless Technology today, are robust, easy to use, and are portable as there are no cables involved. Apart from local area networks, even Metropolitan Area networks have started using Wi-fi tech (WMAN) and Customer Premises Equipment ( CPE ). Aviation, Transportation and the Military use wireless technologies in the form of Satellite communications. Without using interconnecting wires, wireless technologies are also used in transferring energy from a power source to a load, given that the load doesn’t have a built-in power source.However, the fact that ‘nothing comes without a drawback’ or ‘nothing is perfect’ also applies to Wi-fi technology. Wireless technologies still have limitations, but scientists are currently working on it to remove the drawbacks and add to the benefits. The main limitation is that Wireless technologies such as Bluetooth and Wi-Fi can only be used in a limited area. The wireless signals can be broadcasted only to a particular distance. Devices outside of this range won’t be able to use Wi-Fi or Bluetooth. But the distance limitation is becoming reduced every year. There are also a few security limitations which hackers can exploit to cause harm in a wireless network. But Wireless technologies with better security features have started to come out. So this is not going to be a problem for long.Speaking of progress, Wi-Fi technology is not limited to powerful computers and mobile handsets. The technology has progressed enough that Wi-Fi enabled TVs and microwaves have started appearing in the markets. The latest and the most talked-about wireless technology is the NFC or Near Field Communication, which lets users exchange data by tapping their devices together. Using wireless technologies are not as expensive as it used to be in the last decade. With each passing year, newer and better wireless technologies arrive with greater benefits.
