2.4 GHz vs 5 GHz

2.4GHz

advantage

• Has the longest signal range from 45 meter indoors to 92 meters
• Can pass through walls and other solid objects

disadvantage

• The long signal range also increases the chances of Wi-Fi traffic being intercepted by cybercriminals.
• Includes a limited number of channels. Can range from 11 to 14 channels
• Can experience network traffic congestion and interference with other Wi-Fi networks and wireless technologies , such as BlueTooth, that overlap the 2.4 GHz frequency bands.
• Microwave ovens also work in the 2.4 GHz frequency band and can cause Wi-Fi interference
• Under specific condition, the maximum achievable data rate is 600 Mbps

5GHz

advantage

• Includes significantly more channels than 2.4GHz
• Experiences fewer interference problems and less wireless network traffic congestion than 2.5 GHz.
• Can achieve over 2Gbps data transfer speeds under specific conditions

disadvantage

• The wireless range is limited to 50 feet (12 meters) indoors and (30 meters) outdoor
• Does not penetrate walls and other solid objects as well as 2.4 GHz
