Record of Wireless Technologies
The development of Wireless techinical owes it all to Michael Faraday - for finding out 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 cientos. The sole purpose of Wi-Fi technology is wireless communication, in which information can be transferred between two or more points that are not even connected by electrical conductors.
Wireless technologies were in use since the advent of radios, which use electromagnetic transmissions. Gradually, 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, in which led to the discovery of Wireless communications that we notice everywhere now.
History
With the radios being used for handheld communications in the World war era, scientists and inventors begun focusing on means to developing wireless phones. The radio soon has become available for consumers and by mid 1980s, wireless cell phones or mobile phones started to appear. In the late 1990s, mobile phone devices gained huge prominence with over 50 million buyers worldwide. Then the concept of wireless internet and its possibilities happen to be taken into account. Eventually, the wireless internet technology came into existence. The gave a boost to the growth of wireless technology, which usually comes in many forms at present.
Applications of Wireless Technologies
The rapid progress of wireless technology led to typically the invention of mobile phones which uses radio waves permit communication from different locations around the world. The application of wireless mechanic now ranges from wireless data communications in various spheres including medicine, military etc to wireless energy transfers and wireless interface of computer peripherals. Point to place, point to multipoint, broadcasting etc are all possible and uncomplicated now with the use of wireless.
The most widely used Wi-Fi tech will be Bluetooth, which uses short wavelength radio transmissions to plug and communicate with other compatible electronic devices. This technology is continuing to grow to a phase where wireless keyboards, mouse and other peripherals can be connected to a computer. Wireless technologies are used:
- On a trip
- In Hotels
- In Business
- In Wireless and voice communication
- In Home networking
- In Navigation systems
- In Video game consoles
- On quality control systems
The greatest benefit of Wireless like Wi-Fi is the portability. For distances between devices where cables isn't an option, technologies like Wi-Fi can be used. Wi-fi mail messages can also provide as a backup communications link in case of community failures. One can even use wireless technologies to use data expert services even if he's stuck in the middle of the ocean. However , Handheld still have slower response times compared to wired calls and interfaces. But this gap is getting narrower utilizing each passing year.
Progress of Wireless technology
Wireless network 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 joined devices are possible. Personal network of computers can now be created using Wi-Fi, which also allows data providers to be shared by multiple systems connected to the networking.
Wireless technologies with faster speeds at 5 ghz and transmission capabilities were quite expensive when they were developed. But now, almost all mobile handsets and mini personal computers come with technologies like Wi-Fi and Bluetooth, although through variable data transfer speeds. Wireless have grown to this type of level, where even mobile handsets can act as Wi-Fi hotspots, enabling other handsets or computers connected to a special Wi-Fi hotspot enabled handset, can share cellular details services and other information. Streaming audio and video information wirelessly from the cell phone to a TV or computer is actually a walk in the park now.
Wireless Technology today, will be robust, easy to use, and are portable as there are no wires involved. Apart from local area networks, even Metropolitan Area structures have started using Wi-fi tech (WMAN) and Client Premises Equipment ( CPE ). Aviation, Transportation as well as Military use wireless technologies in the form of Satellite communications. Without employing interconnecting wires, wireless technologies are also used in transferring energy levels from a power source to a load, given that the load does not have any a built-in power source.
However , the fact that 'nothing happens without a drawback' or 'nothing is perfect' also pertains to Wi-fi technology. Wireless technologies still have limitations, and yet scientists are currently working on it to remove the drawbacks and also add to the benefits. The main limitation is that Wireless technological innovations such as Bluetooth and Wi-Fi can only be used from a limited area. The wireless signals can be broadcasted to a particular distance. Devices outside of this range won't be qualified to use Wi-Fi or Bluetooth. But the distance limitation is getting 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 experience started to come out. So this is not going to be a problem for rather long.
Speaking of progress, Wi-Fi technology is not limited to powerful portable computers and mobile handsets. The technology has progressed ample that Wi-Fi enabled TVs and microwaves have began appearing in the markets. The latest and the most talked-about wireless network technology is the NFC or Near Field Communication, which will lets users exchange data by tapping their equipment together. Using wireless technologies are not as expensive because used to be in the last decade. With each passing year, more sophisticated and better wireless technologies arrive with greater many benefits.
Conclusion
Wi-fi technologies have become vital for business firms and ordinary consumers alike. Offering speed, security plus mobility, wireless backhaul technologies are used even in Phone over Internet Protocols (VOIP). Schools and Educational firms have started using Wi-fi networks. Technical events as well as video game tournaments now use Wireless connections to connect visitors to a network. The applications, use and demand regarding Wireless technologies keep increasing every year, making it one of the most substantial inventions of this century. It can be concluded that Wireless technologies could be advancing to greater heights in the coming years.
