Some Basic Components of Electronic Communications System

In the electronic communication, transmission, reception, and processing of different signals that carry information or data are included. The communication is between one or more locations around the globe. Some of the basic components required for a successful electronic communication are- transmitter, channel or medium through which the information travels, receiver, RF spectrum analyzer, and, noise.

In the communication system, the input signal (that can be a human voice or an information signal) also known as an analog signal or digital signal acts as the input signals. These input signals are fed in the transmitter. It is important to add here that the information in the input is signal is transmitted in the coded form. The system is said to be reliable and effective when errors are minimized in the process.

Transmitter- As discussed above, a transmitter is the collection of the various number of electronic devices that converts the original signal (baseband signal) into the encoded form. For example, the transmitted signal is passed through the radio transmitter that accepts the information signal and converts it into radio frequency signal. Radio signals are required if the communication or transmission is done to cover the long distance. To check the performance and the strength of the signal, RF spectrum analyzers are required. It shows the strength as well as the noise level of the signal. The signal always travels on a specific frequency. To broadcast a signal either the analog or digital modulations are used.

Communications channel- The channel is the medium through which the signals can be sent from one place to another. The channel can be a copper wire, fiber optics or satellite systems. The channels can be a radio wave and a free space also. It all depends on the nature of the modulation and frequency which is used while communication.

Receiver- The receiver works similarly to the transmitter. The receiver also includes a lot of different transmission mediums and then converts those signals or decode them into the original form. Sometimes the signal gets corrupted or attenuated by certain noise signals, but the receiver removes the attenuation up to some extent.

Introduction to satellite communication - AVCOM

Satellites are the backbone of our wireless communication system. Without them, it's impossible to have long distance communication. There are different types of the satellites which help us in information transfer and communication purposes. Satellite communication, also known as SATCOM require extreme accuracy and reliability as they are the only source of communication for some sectors, such as military, aircraft communication, space crafts and other governmental sectors.

The working and performance of the SATCOM must be continuous and uninterrupted as the environmental factor is one of the major reasons that affect communication of satellite. It helps in sending and receiving the signals between geostationary satellite satellites and antennas installed on earth. They are used to amplify the signals before sending them to the receiver part and relay the signals back to the earth. Satellite is the only option that you can use to cover far distances and wider areas as it uses radio waves and microwaves for communication. 

Due to rise in cross-polarization interference, illegal signals that enter into the transmitted signals while transmission, increase the demand for the detection of these interferences. This has increased the need for Satellite Spectrum Analyzer, as they are used to analyze the signals and their working. 

Some of the other challenges that are seen during the transmission of the signals are ionospheric scintillation. The ions affect the transmission of the signals that result in the degradation of the transmitted signal. The troposphere in the atmosphere can also cause transmission problems. To deal with such problems the communication equipment and devices are manufactured in such a way that they overcome the above-mentioned problems easily.

So, it is very important to install the devices which have the ability to communicate point to point links, high speed, a communication system that can be effective for both defense and commercial use. If you want to buy sound and tap-proof satellite spectrum analyzers, contact- Avcom.  

Why is Remote Spectrum Monitoring Important?

Due to increasing demand for a robust wireless communication system, the demand for analyzing signal transmitted or receiving is increasing. As there are many instruments and various types of equipment which are required to complete the communication part. The interference continuously grows which ultimately decreases the quality as well as the efficiency of the network. Some of the illegal and unlicensed signals may degrade the signal. Finding them or not to enter into the already transmitted signals or removal of these signals is a challenge. To filter the transmitted or receiving signals, remote spectrum monitoring is required.

The systems used to monitor spectrum helps in the identification of unlicensed and illegal signals which create interference in the other signals. In addition to that, these monitoring systems are used to remove them and patterns of these illegals systems can be detected which identify the location of the signals and location of the source which produce such signals. 

Not only in wireless network providers but there are certain other departments where such remote monitoring systems are required. Defense is one of the main and important departments which always want to sure its own system as well as limit the entry of illegal or unlicensed signals. Since the data and information is the top priority for the defense. They need to check the intruder signals which may corrupt the signal and even the whole data system. Monitoring these frequency bands gives the information required to optimize spectrum for maximum utilization. By using techniques such as- cognitive radio, the spectrum can be reused for other purposes and can be blend with the signals. 

Some of the other important departments are- police, firefighters, air traffic control, navel, and during emergency services. All these have access to communicate free of restrictions and distortion. Various agreement with spectrum providers is often required by spectrum monitoring. They are mainly required near the border areas to check the movement of the neighboring country or to stop the illegal migration of people as well as the illegal exchange of goods.
