From staying in touch with friends to managing a business, mobile technology plays a crucial role. From the smallest hand-held devices to sophisticated smartphones, it has changed our world for the better in countless ways.
Why Cell Phones Talk To One Another
Imagine if several people all called you at the same time on their cellphones. If the phones used the same kind of radio signals, the calls would interfere and scramble together, making them impossible to distinguish. But if each call uses a different frequency (the number of up-and-down undulations in a radio wave per second), the calls are easy to separate. This is how cellphones work to communicate with each other over long distances.
3G Connection-Based Wireless Mobile Technology
As the Internet grew in popularity, cellphones needed faster connections to handle the demand. In the mid-2000s, 3G cellphones came to market, offering much faster Internet connections than EDGE or GPRS, which had been available for some time. 3G also increased capacity for video calling, music downloads and other high-demand services.
4G Technology
After 3G, the need for even faster Internet access prompted the development of the fourth generation (4G) of cellphone technology. Sometimes called LTE, this system offers data rates of up to 10MBps, significantly faster than the 2Mbps of UMTS.
As a result of the COVID-19 pandemic, the business world has rapidly moved to adopt mobile communication technologies. Many of the paper memos, bulletin boards and water cooler conversations that characterized the organizational landscape in prior decades have been supplanted by mobile tools like email, social media and instant messaging. This trend was accelerated by the need to support a remote workforce during the pandemic, and by the rise of digital communication platforms that allow business customers and employees to connect from anywhere.
