We discover in the hidden realm of wireless connections that Wi-Fi and private LTE both provide internet access but in different ways. Information transmission is their crucial distinction, which affects how they communicate. A little technical issue affects your link’s security, range, and speed. Learn about these two methods to make sensible decisions and choose the finest technologies.

Wi-Fi signal transmission

Wi-Fi operates mainly in two open radio bands:

  1. 2.4 GHz: This band offers a more extensive range, but microwave ovens, Bluetooth devices, and other Wi-Fi networks using the same channel might damage it.
  2. 5 GHz: This frequency provides quicker speeds and less interference than 2.4 GHz, but it has a limited range and has problems passing through walls and solid objects.

The CSMA/CA protocol:

CSMA/CA handles Wi-Fi network traffic and prevents devices from sending data bits that collide. It works:

  • Carrier Sense: Something checks whether the channel is utilized before transmitting data.
  • Clear Channel evaluation: If the channel is open, the gadget waits an undetermined period to reduce accident risk.
  • Transmission: The device transmits data if the channel is clear.
  • Collision monitoring: If a communication error occurs, both devices shut down and attempt again after an indeterminate period.

Broadcast nature

Wi-Fi spreads information via radio waves. This implies the signal can reach any item in its range, even if it’s not supposed to. Though handy for universal internet access, Wi-Fi transmits data, making it less secure. Anyone in the region with a networked device might receive and read unencrypted data.

Private LTE Signal Transmission
