A user in a crowded apartment complex reports that their Wi-Fi connection is slow and drops frequently. The technician discovers the user is connected to the 2.4GHz band on their dual-band router. Which of the following BEST explains why switching to the 5GHz band would likely improve the user's experience?
The 5GHz band has a longer signal range, which can better penetrate the walls of adjacent apartments.
The 5GHz band is required for all modern standards, as 802.11n and 802.11ax do not operate on 2.4GHz.
The 5GHz band has more non-overlapping channels and is less congested by common household devices.
The 5GHz band uses stronger default encryption methods than the 2.4GHz band.
The 5GHz band provides a significant advantage in environments with high wireless congestion. It has many more non-overlapping channels (typically 23-25) compared to the 2.4GHz band (which has only 3). Furthermore, the 2.4GHz band is crowded with signals from other Wi-Fi networks and non-Wi-Fi devices like microwave ovens, cordless phones, and Bluetooth devices, which causes significant interference. The 5GHz band is less susceptible to this type of congestion and interference, resulting in a more stable and often faster connection. While 2.4GHz signals have a longer range, this is a disadvantage in a crowded area as it increases the number of interfering neighboring networks.
