A wireless transmission at 2.4 GHz gives internet to a bigger region but sacrifices the fast internet speed. 5 GHz gives quicker speeds but restricts itself to a smaller area.

2.4 GHz Frequency vs 5 GHz (Gigahertz)

2.4 GHz (Gigahertz) Frequency

  • 2.4 GHz is a long rang.
  • It is slower speeds.
  • 2.4 GHz has a max speed of 150 Mbps speed.
  • it is Higher possibility for interference.
  • it is 11 Different channels only.
  • A dual-band wireless devices less expensive.
  • High performance to penetrating solid objects.

5 GHz (Gigahertz) Frequency

  • 5 GHz is a short range.
  • maximum speed of 1 Gbps data transfer.
  • Poor performance to penetrate solid objects.
  • it is 23 Different channels only.
  • A Dual-band router is more expensive.

2.4GHZ Advantages

  • it is a Farther range.
  • penetrating solid objects is better performance.

2.4GHZ Disadvantages

  • Vulnerable to interference
  • It is a slow speed.
2.4 GHZ vs 5 GHZ wavelengths
