Mobile Network Speed

Chapter 11 traces the evolution of mobile network speeds from 1G to 6G, highlighting exponential growth in data rates over four decades. 1G networks in the 1980s supported only analog voice calls, while 2G introduced digital communication and basic data services. 2.5G added packet switching and “always-on” internet with speeds up to 114 kb/s. 3G enabled multimedia applications and video calls, reaching 2 Mb/s, followed by 3.5G with HSPA+ offering 42 Mb/s downloads. 4G LTE and LTE Advanced brought widespread MIMO technology, achieving up to 1 Gb/s. 5G introduced massive MIMO and millimeter-wave bands, with theoretical speeds of 20 Gb/s downlink. 6G, still in development, aims for terabit-per-second speeds, ultra-low latency, and massive device connectivity by 2030. Overall, mobile network data rates have increased by more than seven orders of magnitude, doubling approximately every 1.8 years, driven by innovations beyond Moore’s law.
