The 2.4 GHz and 5 GHz wireless networks are wireless communications wireless networks. Each is distinct in advantage and disadvantage depending on application.
Feature
2.4 GHz
5 GHz
Speed
Slower (max ~600 Mbps, depending on Wi-Fi standard)
Faster (up to several Gbps, depending on Wi-Fi standard)
Range
Longer range (penetrates walls and obstacles better)
Shorter range (weaker penetration through walls)
Interference
More interference (crowded band with Bluetooth, microwaves, etc.)
Less interference (fewer devices use this frequency)
Best Use Cases
Large coverage, better for long-distance connections and obstacles
High-speed applications (gaming, streaming) in close proximity
Below given charts are generated from example data sets, the actual WiFi signal and bandwidth may vary on your environment.
Use 2.4 GHz if: You need better cover and longer range. You have interference or partitions between the router and the device. Your internet is slower than 100 Mbps and is not a top-level offering.

Use 5 GHz if: You need higher speeds for video conferencing, online games, or video streams. You are in close proximity to the router with fewer obstacles. You want there to be fewer interference sources. Dual-Band and Tri-Band Routers
