The development of Wireless technology owes everthing to Michael Faraday – for getting the principle of electromagnetic induction, to James Maxwell – for the Maxwell’s equations in order to Guglielmo Marconi – for transmitting a wireless signal over one and a half miles. The sole purpose of Wi-Fi technological know-how is wireless communication, through which information can be transferred between some points that are not connected by means of electrical conductors.
Wireless technologies were utilized since the advent of radios, which use electromagnetic transmissions. Eventually, consumer electronics manufacturers started thinking about the possibilities of automating domestic microcontroller structured devices. Timely and reliable relay connected with sensor data and controller commands were being soon achieved, which led to the discovery of Wireless communications that any of us see everywhere now.
With the radios being used for wireless communications on this planet war era, scientists and inventors started working on means to developing wireless phones. Radio stations soon became available for consumers in addition to by mid 1980s, wireless phones or mobile phone devices started to appear. In the later 1990s, mobile phones gained huge prominence with over 50 million users world-wide. Then the concept of wireless internet and its possibilities were thought about. Eventually, the wireless internet technology has been around since. This gave a boost to this growth of wireless technology, which can be purchased in many forms at present.
Applications connected with Wireless Technology
The rapid progress of wireless technology concluded in the invention of mobile phones which uses radio waves help communication from different locations world wide. The application of wireless tech at this point ranges from wireless data communications in various fields including medicine, military etc to help wireless energy transfers and wireless screen of computer peripherals. Point to position, point to multipoint, broadcasting etc are all possible and easy now while using wireless.
The most widely used Wi-Fi tech would be the Bluetooth, which uses short wavelength radio transmissions to touch base and communicate with other compatible electronics. This technology has grown to some sort of phase where wireless keyboards, mouse along with peripherals can be connected to your working computer. Wireless technologies are used:
· While traveling
· In Hotels
· In Small business
· In Mobile and voice verbal exchanges
· In Home networking
· In Navigation systems
· In Video game consoles
· With quality control systems
The greatest selling point of Wireless like Wi-Fi is the portability. For distances between devices where cabling isn’t a solution, technologies like Wi-Fi can be utilised. Wi-fi communications can also provide as a backup communications link in the case of network failures. One can even use wireless technologies make use of data services even if he’s stuck down the middle of the ocean. However, Wireless still have slower response times when compared to wired communications and interfaces. But this gap is getting narrower with each passing year.
Advance of Wireless technology
Wireless data communications now also come in technologies namely Wi-Fi (a wireless local area network), cellular data services like GPRS, EDGE and 3G, and cell phone satellite communications. Point-to-point communication was a lrage benefit decades ago. But now, point-to-multipoint in addition to wireless data streaming to multiple wirelessly hooked up devices are possible. Personal network of computers are now able to be created using Wi-Fi, which also allows data services for being shared by multiple systems connected towards network.
Wireless technologies with faster speeds on 5 ghz and transmission capabilities were very costly when they were invented. But at this point, almost all mobile handsets and mini computers accompany technologies like Wi-Fi and Bluetooth, while with variable data transfer speeds. Wireless have grown to such a level, where even mobile handsets can represent Wi-Fi hotspots, enabling other handsets or computers linked with a particular Wi-Fi hotspot enabled mobile phone, can share cellular data services along with information. Streaming audio and video data wirelessly on the cell phone to a TV or computer is usually a walk in the park now.
Wi-fi Technology today, are robust, easy make use of, and are portable as there usually are no cables involved. Apart from local area networks, even Metropolitan Area networks include started using Wi-fi tech (WMAN) in addition to Customer Premises Equipment (CPE). Aviation, Transportation and the Military use wireless technologies such as Satellite communications. Without using interconnecting electrical wires, wireless technologies are also used in transferring energy at a power source to a load, provided that the load doesn’t have a built-in electric power source.
However, the fact that ‘nothing comes with not a drawback’ or ‘nothing is perfect’ also is true of Wi-fi technology. Wireless technologies still include limitations, but scientists are currently working on there to remove the drawbacks and boost benefits. The main limitation is that Wireless technologies like Bluetooth and Wi-Fi can only double in a limited area. The wireless signals is usually broadcasted only to a particular mileage. Devices outside of this range won’t have the capacity to use Wi-Fi or Bluetooth. But the distance limitation is becoming reduced every season. There are also a few safety measures limitations which hackers can exploit to cause harm within a wireless network. But Wireless technologies with better security features have started to come out. So this is not going as a problem for long.
