History of Wireless Technologies
https://digitalsjournal.com/technology/look-wellsaid-vocalid-aihao-mit-technologyreview/ The development of Wireless technology owes it all to Michael Faraday – for discovering the principle of electromagnetic induction, to James Maxwell – for Maxwell’s equations, and to Guglielmo Marconi – for transmitting a wireless signal over one and a half miles.
Wireless technologies were in use since the advent of radios, which use electromagnetic transmissions. Eventually, consumer electronics manufacturers started thinking about the possibility of automating domestic microcontroller-based devices.
https://worldspaper.com/ With the radios being used for wireless communications in the World war era, scientists and inventors started focusing on means to develop wireless phones. The radio soon became available for consumers and by the 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, 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 Technology
The 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 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, mice, 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 systems
The greatest benefit of Wireless like Wi-Fi is 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 has slower response times compared to wired communications and interfaces. But this gap is getting narrower with each passing year.
Progress of Wireless technology
Wireless 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 networks 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 Technology today, is robust, easy to use, and 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.
Nothing comes without a drawback
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 them 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 that 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 NFC or Near Field Communication, which lets users exchange data by tapping their devices together. Using wireless technologies is 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.
Wi-fi technologies have become vital for business organizations and ordinary consumers alike. Offering speed, security, and mobility, wireless backhaul technologies are used even in Voice over Internet Protocols (VOIP). Schools and Educational institutions have started using Wi-fi networks.
Technical events and video game tournaments now use Wireless connections to connect users to a network. The applications, use, and demand of Wireless technologies keep increasing every year, making it one of the most significant inventions of this century. It can be concluded that Wireless technologies will be advancing to greater heights in the coming years.
