The exchange of information or energy from one device to another without any physical connection is called wireless technology. Earlier machines were connected to each other using massive wired networks. This required a lot of space and even maintenance costs. But since the advent of technology, wireless networks have become very popular. Wireless networks have made it easier to transfer information from one place to another. They have made this exchange fast and accurate. The earliest known example of a wireless network is radio. The frequencies exchanged by two radio devices were used to exchange information across borders. Since the time of the radio, the wireless industry has evolved manifold. From Bluetooth to broadband and Wi-Fi, the wireless connectivity has reached new levels of success. Its use as a network application has multiplied.
The major revolution in wireless applications took place in the 1990s. There was a huge shift from wired networks to wireless networks. The advent of this technology made it easier to share information and media from one device to another such as text messages, images, audios, and videos. Earlier Bluetooth was used to share images and audios from one device to another. But now we have applications such as cloud or share it which makes it very easy to share a lot of data with another mobile device. Wireless has changed the way we consume data and share information between machine and humans. These applications are basically improved wireless networks which are employed to either store or share data from one device to another. This sharing is done at great speed, making it very convenient to use. Wireless networks are also used in printers nowadays. There is no need for attaching your laptop or computer to a printer using wires. One can simply connect the two devices using a common wifi network and share the file to be printed. Wifi is the most excellent example of a wireless network. It is a network that provides high-speed internet and common networks. It is a simple wireless area network (WLAN). Wifi networks are used for domestic as well as business purposes. Nowadays every home and office has a strong wifi network. It makes it easier for laptops, computers and mobile devices to use the internet at a high speed. This broadband network is a miracle of the wireless industry.
The wireless industry also includes our mobile networks. We have seen mobile networks progress from 2G to even 5G now. Until now, these networks were used only in mobile devices for using the internet. But the 5G network can be used on other devices as well. It will provide the device with excellent speed internet. It will have great performance and efficiency at a very convenient price. It will also help in creating smart cities by connecting traffic signals and emergency vehicles. It will also aid smart cars to function to their optimum capacity on roads. This technology is most likely to gain popularity in the early 2020s. Another very interesting concept in wireless technology is IoT (Internet of Things). Nowadays it is not only humans who require the internet. The Internet has become important in machines in various fields such as banking and finance, research, security and many more. The IoT enables machines and other devices to get access to high-speed internet without using any wires. Earlier people had to be physically present to monitor machines under their control. But now it has become possible to troubleshoot problems through cloud technology. This saves time and increases work efficiency.
The past few years have seen a revolutionary change in the wireless industry. From wired headphones to airpods and earbuds, we have now entered a totally wireless world. With new innovations and technologies coming in every day, we are about to witness the next great move in wireless technology.
