What is disadvantages of 5th generation?

Fifth-generation (5G) technology faces several disadvantages, including limited coverage in rural areas due to the need for more infrastructure, which can be costly and time-consuming to deploy. Additionally, higher frequency bands used in 5G can have reduced penetration through obstacles like buildings, leading to potential connectivity issues indoors. There are also concerns about security vulnerabilities and the potential health impacts of increased exposure to electromagnetic radiation. Lastly, the high costs associated with upgrading existing networks and devices can be a barrier to widespread adoption.
