Implementing 5G technology poses several challenges, including significant infrastructure upgrades that require extensive investments in network components like small cells and fiber optics. 5G technology demands a denser network to achieve its high speeds and low latency, complicating installation and maintenance. Additionally, regulatory hurdles and spectrum allocation issues can impede deployment timelines. The transition from existing networks to 5G can also cause compatibility concerns, as devices must support new frequencies. Lastly, the required security measures must be established to address vulnerabilities associated with increased connectivity, making implementation more complex.
