The wires of mobile devices will be wiped out of the map, becoming a thing of the past. This perception has been reinforced after the new iPhone from Apple, which comes with headphones that connect to the appliance without any type of wire thanks to a wireless technology developed by the company. Other companies have been studying ways to accelerate the speed of data transmission up to 100 times the current speed. Wireless technology allows the exchange of information between mobile or fixed devices through a wireless connection. The transmission of such data can be done in several ways: radio, satellite, infrared radiation or electromagnetic radiation (used in walkie-talkies). The data are sent to a central point where they are captured and transmitted to devices connected to that network. “There will be a revolution in the wireless technology field”, says Arie Halpern, economist, and entrepreneur with a focus on innovation and disruptive technologies. According to him, the arrival of other disruptures such as the internet of things will cause the wireless technology to become faster and better.
On launching the iPhone 7 with wireless headphones, Apple declared that its wireless system is better than the Bluetooth (a different transmission system). The headphones use a chip called W1, developed by Apple, to improve the connection quality and speed. It also allows the headphones to be able to “feel” when they’re in the user’s ears and stop playing when taken out.
Another novelty in this area is Li-fi, an alternative to Wi-Fi, used to connect computers to the Internet. The Li-Fi is still in its testing phase, but promises an improvement in speed and quality of internet connections, explains Arie Halpern. Companies around the world are interested in participating in this development. What draws more attention about the Li-Fi is the way it works: through LED lamps. Data transmission is made possible by turning the lamp on and off so quickly that the action is imperceptible. The light is registered by a sensor, responsible for transforming it into information. The technology reaches areas where Wi-Fi does not work and, in tests, it has already managed to reach speeds of 1Gbps (1000 megabytes per second).
Having all this evolution in mind, it is recommended to keep an eye on the safety of these connections. With the increasing number of devices connected to networks, our data may become a banquet for hackers; we should then protect ourselves, says Arie Halpern. Fortunately, MIT scientists are already working to ensure data protection. The Computer Science and Artificial Intelligence Laboratory of the Massachusetts Institute of Technology has developed a system called Chronos that allows Wi-Fi access points to correctly locate the position of a user without the need for sensors. Chronos is so precise that can help locate missing devices and control fleets of drones.
