It takes a long time for each generation of wireless communication technology to become broadly available primarily because the network infrastructure and cell towers need significant upgrades to support the new generation hardware. Additionally, devices compatible with the new generation often become available only years after the network is fully rolled out. Consumer resistance to change and limited demand for greater bandwidth also slow adoption. Moreover, the previous generation's infrastructure sometimes needs to be managed alongside the rollout, complicating the transition. These factors combined—extensive infrastructure upgrades, device availability delays, and consumer behavior—create a complex and lengthy timeline for widespread adoption of each new wireless generation.
