The wireless intercom system is simple and convenient to operate, and is ideal for tasks such as aerial work and remote command scenarios. It provides flexibility by overcoming obstacles and interference caused by buildings. The system ensures minimal interference, smooth operation without obstacles, and provides wide availability. However, it should be noted that certain factors can cause interference to wireless intercom systems, such as radio waves, industrial electrical equipment, and electromagnetic sources. Let’s get into the details.

First, let’s explore the characteristics of wireless intercom systems:

1. Easy and fast operation, high flexibility:

The wireless intercom system is designed for direct and flexible operation, allowing fast voice transmission. The system enables multi-party communication without pressing any buttons. It allows talking and listening at the same time, without the need for a host or repeater. With simple settings, the wireless intercom system can be easily operated. It is suitable for applications such as aerial work, radio command, and remote communication.

2. Wide coverage:

The wireless intercom system adopts traditional wireless communication technology and full-duplex communication mode to ensure seamless communication coverage between buildings without blind spots, overcome the obstacles of building structure and environmental factors, and the signal is unimpeded from the ground to the underground layer, achieving full coverage in actual scenarios.

3. High call quality:

High-quality wireless intercom systems minimize the interference of antenna radiation to other systems in the building while ensuring high-quality call transmission, strictly abide by the standard that the electromagnetic wave interference field strength within a certain range does not exceed 3V/m, ensure excellent call quality, and avoid interference with other nearby systems.

2.Interference factors of wireless intercom system

1. Radio interference:

This type of interference comes from various wireless transmitters with a wide frequency range, covering the most commonly used frequency bands. However, specific sites operate at fixed frequencies, so protective measures can be taken. In addition, due to comprehensive radio frequency management, this type of interference can be limited to a small range.

2. Industrial interference:

Industrial interference comes from various electrical equipment, including motors, power lines, power switches, and electronic ignition devices (such as car ignition devices). This type of interference usually occurs in the lower frequency range, such as car ignition interference in the tens of megahertz range. Industrial interference can be greatly mitigated by implementing effective shielding and advanced filtering technology.

3. Electrical interference:

Electrical interference originates from natural phenomena such as lightning, magnetic storms, sunspots, and cosmic rays. These interferences are closely related to seasonal and climate changes and show obvious regional differences. For example, areas near the equator have different interference patterns compared to other areas. During the period of sunspot changes (a cycle of about 11 years), sky and electrical interference will intensify, sometimes resulting in long-term interruption of shortwave communications.

4. Communication interference:

Communication interference originates from various electronic components, resistors, antennas and transmission lines within the communication channel. The random thermal motion of molecules or electrons in these electronic devices generates so-called ripple noise, which causes additional interference to the communication signal. This noise is usually called thermal noise, follows a Gaussian statistical pattern, and is an important factor in communication system interference.
