The advent of 5G technology marks a significant milestone in the evolution of
wireless communication. It promises not only higher data speeds but also lower
latency and greater network capacity, enabling a wide range of applications
and services. To comprehend the potential interference between 5G and Wi-Fi,
it is essential to grasp the fundamental principles of 5G technology.

A. Explanation of the fundamental principles of 5G technology:

Increased Frequencies: 5G networks utilize a broader range of
frequencies compared to previous generations. While 4G predominantly operates
in lower frequency bands, 5G networks extend into higher frequency bands,
including millimeter-wave (mmWave) frequencies.

Small Cell Deployment: 5G networks rely on a dense network of small cells, which are compact and
low-power base stations deployed in close proximity to each other. This
deployment strategy enables better coverage and capacity in urban areas.

Massive MIMO: Multiple-Input Multiple-Output (MIMO) technology plays a vital role in 5G.
Massive MIMO employs a large number of antennas at the base stations, allowing
for improved spectral efficiency, increased capacity, and enhanced beamforming
capabilities.

extremely fast data rates. However, they have shorter range and are
susceptible to signal blockage by physical obstacles.

C. Overview of the different types of 5G deployments:

mmWave Deployment: This deployment involves utilizing high-frequency
mmWave bands for 5G, which offer ultra-fast speeds but have limited coverage.
Due to the shorter wavelength, mmWave signals are more susceptible to
obstruction by buildings, trees, and other obstacles.

Sub-6 GHz Deployment:
Sub-6 GHz deployment utilizes lower-frequency bands below 6 GHz, which provide
wider coverage and better penetration through obstacles. These bands offer a
balance between coverage and capacity, making them suitable for both urban and
rural areas.
