What are the biggest disadvantages to using wireless network access?

The biggest disadvantages of using wireless network access primarily include range, reliability, and security issues. Wireless networks, while offering mobility and convenience, can suffer from a range of limitations.

Range is a significant consideration because the effectiveness of a wireless network can diminish with distance from the access point. Walls, furniture, and other obstructions can further limit the coverage area, leading to dead spots where the signal is weak or nonexistent.

Reliability is another critical concern. Wireless signals can be affected by various factors, such as environmental interference from other electronic devices, physical barriers, and even weather conditions. This can result in inconsistent connectivity and varying signal quality, making the network less dependable than wired connections.

Security is also a major disadvantage with wireless networks. Unlike wired connections that have physical access points, wireless networks are more susceptible to unauthorized access. Without proper encryption and security protocols, sensitive data transmitted over a wireless network can be intercepted more easily than if it were transmitted through wired lines.

Considering these factors, option D accurately encompasses the key disadvantages of wireless network access, highlighting why this choice is the most relevant.
