Which Frequencies Minimize RF Interference in Manufacturing Facilities?

A network engineer for a manufacturing company is implementing a wireless network that provides reliable coverage throughout the facility.

There are several large, electric, motorized machines installed on the shop floor for automating the manufacturing process.

These machines are known to be significant sources of RF interference.

Which of the following frequencies should the wireless network use to MINIMIZE this interference?

A.

2.4 GHz

B.

56MHz

C.

5GHz

D.

900MHz.

C.

The wireless network engineer needs to choose the frequency that will minimize the interference caused by the large, electric, motorized machines on the shop floor.

Generally, wireless signals are transmitted at different frequencies, measured in Hertz (Hz). These frequencies are divided into bands or channels, and each band has a different range of frequencies.

The most common frequencies used for wireless networks are 2.4 GHz and 5 GHz. 900MHz and 56MHz are less common frequencies used in specialized applications.

In this scenario, the best frequency to minimize RF interference caused by the machines would be 5 GHz. This is because 5 GHz signals have a shorter wavelength than 2.4 GHz signals and are less likely to be affected by the large, electric, motorized machines.

Moreover, 5 GHz frequency is less congested compared to 2.4 GHz frequency, as it is less commonly used by other wireless devices, and provides higher data rates.

Therefore, selecting 5 GHz frequency would provide reliable wireless coverage and minimize the interference caused by the large, electric, motorized machines in the manufacturing facility.
