In wireless communication, wireless LAN offers higher throughput, but its coverage is, in general, more limited than cellular (wireless WAN). This exchange between communication range and throughput has been identified earlier in the ISSCC 2013 trend tracking report [6][7], as shown in Figure

increased at a rate of approximately ten times every five years. Although the exact triggers of this data-rate increase are not easily identifiable, some possible contributors may be. First, there is the effect of the form factor of smart devices (including phones, laptops, and tablets) as they finally became truly portable. Multi-disciplinary technological advancement, including process technology, circuit innovation, display evolution, packaging innovation, thermal engineering, and more have enabled form-factor reduction. The second possible contributor has been the improvement in wireless infrastructure. Independent of form-factor reduction, the users before Cloud 1.0 had only limited ability to leverage the power of the cloud without satisfactory access to the Internet. Within the Cloud 1.0 Era, the deficiency of Internet access was reduced through the introduction of WLAN hot spots, the increased coverage of cellular infrastructure, and the evolution
