A mobile phone is basically a radio. It uses a combination of signals (radio waves, electrical energy and optical fibre) to transmit data from one point to another. It also enables users to make voice calls, send text messages and use applications.
Modern cellular systems are designed to accommodate thousands of simultaneous telephone conversations. Each cell is allocated a specific area of radio frequency, which allows multiple conversations to occur simultaneously within that service area (more on this topic later). The number of voice channels available in each cell is increased with digital transmission methods such as TDMA and CDMA.
The first generation of mobile phones used analog technology and was launched in the 1980s. The second generation introduced digital networks, enabling mobile devices to connect to the internet. The third generation, commonly known as 3G, introduced faster download speeds and a larger network capacity. The fourth generation, 4G LTE, further improved maximum network speeds and reduced latency times. The fifth generation, 5G, is poised to deliver even higher network speeds.
While a lack of seamless connectivity was among the top frustrations reported by mobile device users in our Aberdeen study, newer mobile technologies are designed to eliminate these limitations. For instance, 5G promises to enable robust processing and superior connectivity across a wide range of devices.
Whether you’re planning to build a simple MVP or highly interactive, feature-rich mobile app, it’s important to choose the right technology stack to ensure optimal performance and future scalability. The wrong choice could result in slow apps and poor user experiences.
