What Is an Underground Radio Antenna

kristian May 29, 2023 Mining, Mining Communication, Underground Communication, Underground Mining

Though seemingly simple devices are attached to radios, an underground radio antenna plays a crucial role in transforming voltage from transmitters into radio signals and recovering radio signals with receivers. For engineers, especially those new to wireless applications, antennas can appear complex and enigmatic. Becker Mining USA recognizes the importance of understanding underground radio antennas and their operation to establish and maintain dependable connections in mining operations.

Crucial Function of Underground Radio Antennas

Understanding how an underground radio antenna works is vital for ensuring reliable communication in mining operations. Acting as transducers, these antennas convert voltage from transmitters into radio signals and vice versa, picking up and recovering signals in the air. The transmitter applies a voltage at the desired frequency, generating electric and magnetic waves from the antenna. At the receiver, the waves passing over the antenna induce a small voltage, serving as the signal source for the receiver input. Reciprocity is a crucial concept, enabling the same antenna to function for transmission and reception in wireless applications.

Polarization and Antenna Design

Polarization is an essential concept in underground radio antenna design. While vertical antennas receive vertically polarized signals and horizontal antennas receive horizontally polarized signals, real-world antennas rarely align perfectly with either polarization. As a result, antennas can pick up signals with opposite polarization, albeit with some attenuation. Circular polarization provides a solution for precise polarization control by multiplexing two signals on the same frequency. By continuously rotating the polarization during transmission, horizontal or vertical antennas can be used for reception. A circularly polarized receiving antenna is required to maximize the reception of circularly polarized signals. Circular polarization proves invaluable in solving polarization challenges and optimizing antenna performance.

Overcoming Design Worries with Antenna Basics

Despite the critical role of an underground radio antenna, it is often overlooked during the design process due to its perceived complexity. The countless variations in size and shape can be daunting for engineers new to wireless applications. However, a brief review of the basics can alleviate design concerns and help engineers confidently incorporate antennas into their designs.

Dependable Connections for Underground Mining

Maintaining dependable connections in underground mining is a top priority for Becker Mining USA. Understanding how underground radio antennas function is paramount in achieving this goal. The antenna generates the radio wave by applying a voltage to the antenna at the desired frequency. The receiving antenna picks up this wave, converting it to voltage to recover the radio signal. With a solid grasp of antenna functions and the concept of reciprocity, the team at Becker Mining USA has the expertise to design and maintain reliable communication systems in underground mining operations.

How exactly do two-way radios work? For its communication strategy, Becker Mining USA has been providing two-way radios for its customers. These tools are perfect for effective and efficient communication between personnel. Two-way radios, also known as walkie-talkies, allow people to communicate over short distances with a simple button push.

For Becker Mining USA, two-way radio communications have become invaluable tools for keeping employees connected and safe in emergencies. Employees can quickly reach out to each other for help or assistance by using these radios.

Working Principle of Two-way Radios

Two-way radios work by transmitting and receiving signals through radio waves. Radio waves are electromagnetic fields that are capable of carrying audio messages from one place to another without the need for physical wires. Using radio frequencies provided by the FCC, these radio waves travel from one point to another, allowing two individuals to talk back and forth through their radios.

The design of two-way radios plays an essential role in how they function. The receiver is usually located inside the device and works by picking up incoming signals within a specific frequency range. A transmitter generates the outgoing signal — often in the form of an antenna sticking out of the back end of the device — which sends out encoded information so that only people with compatible receivers can pick up your transmission on their own devices.

These days, many two-way radios possess additional features such as privacy codes that help maintain secure conversations or high power output for a more excellent transmission range. For Becker Mining USA specifically, having access to these features provides even more safety and assurance in case of an emergency or a breakdown in communication due to location constraints or any other factors that could leave employees feeling lost without a reliable connection between team members.

Improved Mining Communication

By combining two-way radios with leaky feeder lines, safety conditions improve tenfold in work mines. Leaky feeder lines transmit radio signals through a pressurized tube system in which the signals ‘leak’ out of tiny holes along its length. This setup provides personnel to send and receive radio signals deep within mines or areas that typically block traditional radio waves. As a result, Becker Mining USA can ensure that their employees can stay connected no matter where they are located or their situation. With traditional two-way radios, signal interference in deep mining sites would be typical. Thanks to these extensions, the signal remains evident throughout the mining site. It can also expand as the mining site grows.

In conclusion, two-way radios have quickly grown in popularity as reliable tools for businesses in mining and construction that require frequent connection among personnel without having to rely on bulky sets of wires and cables for every situation possible. Thanks to modern technological advancements, communicating via two-way radios has never been easier or more precise than ever before.

What Type of Radiation Are VHF and UHF Radio Signals

kristian April 24, 2023 Mining, Mining Communication, Underground Communication, Underground Mining

What type of radiation are VHF and UHF radio signals? The world of radio technology is full of terms that can be hard to keep track of, especially when it comes to understanding the different types of radiation associated with radio transmissions. One particularly important distinction is between very high frequency (VHF) and ultra-high frequency (UHF) radio signals.

Types of Radio Signals

Both VHF and UHF radio signals radiation waves are part of the electromagnetic spectrum, but they differ in what type of wavelengths they use. VHF waves typically have a wavelength of 30-300mhz, and UHF waves typically have a wavelength range between 3ghz- 300mhz.

When it comes to the radiation associated with these signals, both VHF and UFH transmit energy via electromagnetic fields in the form of non-ionizing radiation, known as radiofrequency (RF) radiation. RF radiation has long been used in many applications such as cellular communication, television broadcast, radar systems, etc., but there is still debate about potential health risks that could arise from prolonged exposure – according to the American Cancer Society website, no link has been established between any health problems from exposure to RF radiations from consumer products like cell phones or radiotelephone towers.

Radiofrequency

Electromagnetic radiation is an omnipresent form of energy in our universe, spanning galaxies and stars as well as everyday items like cell phones and microwaves. Radiofrequency or RF energy is a type of electromagnetic radiation created by the motion of electrical charges emitted by antennas. Frequency units for these waves can be expressed in Hz or MHz, with lower frequencies represented by longer wavelengths and vice versa. By understanding the basic principles behind this type of radiation, we can use it for our benefit.

What is a Leaky Coax Cable

kristian April 3, 2023 Leaky Feeder Systems, Mining Communication, Underground Communication, Underground Mining

Radio coverage in tunnels is an essential topic of study, especially as more applications require wireless coverage in underground spaces. Leaky coax cable, coupled or radiating leaky mode cables, has been recognized as a viable method of establishing base station antenna systems in such areas. This cable type transmits radio frequency signals using energy and wave radiation patterns on its outer conductor. Through simulations and calculations performed with a modified ray tracing algorithm, it has been demonstrated that leaky cables can achieve better radio frequency (RF) coverage than distributed antennas in signal level versus frequency for different tunnel lengths and cross-section areas.

Leaky Cable for Emergency Communications

Leaky coaxial cables are preferred for tunnel coverage due to the difficulties of using a distributed antenna. By using leaky cables, radio frequency signals can be sent by slotting its outer conductor, and channels can be established based on the wave and energy radiation patterns emitted. This base station system is essential for various applications in underground environments, such as mobile communication (GSM, PCN/PCS, DECT), emergency communication services on roads, radio coverage of railway and metro tunnels, and more. Using leaky coaxial cable deployment, considering both transmission and threshold power levels, a novel implementation of the Ray Tracing algorithm is used to predict radio coverage in tunnels accurately. This improved method makes electric field coverage smoother and easier to predict. Radio communication within tunnels is greatly enhanced when this leaky cable deployment is used.

Leaky coaxial cables provide the structure for electromagnetic waves to propagate as Transverse Electromagnetic (TEM) waves. This cable type is shielded by an outer conductor. This prevents electromagnetic radiation from being influenced by the propagated wave within the cable. However, slots on the outer conductor allow some energy to leak between the cable and its environment. This adjustable coupling capability allows for smoother electric field coverage and better radio communication quality, depending on the amount of electromagnetic intensity, installation method, and environmental conditions within a tunnel. Due to their metallic characteristics, 75 Ω cables have been replaced with more efficient 50 Ω cables to further reduce signal loss in tunnels. These new cables help maximize radio performance and enhance overall coverage within tunnels.

Essential Parameters of Leaky Cables

Two essential parameters of leaky cables are cable attenuations (or longitudinal attenuation) and coupling attenuations. The coupling attenuations refer to the ratio between radiated signal level and the received signal level by a λ/2 dipole antenna or λ/4 monopole at a specific distance from the cable. This ratio can vary depending on the location of the cable, distance, and orientation of slots. Leaky cables can be divided into two models: radiating model and coupled model.

In the radiating mode, an electrical field is generated by slots located on the cable’s outer conductor. These slots are typically spaced at half wavelength distances of radiation signals for maximum output. Meanwhile, in the coupled mode, electromagnetic fields are scattered. It is due to induction on the cable’s outer conductor. This produces a current that radiates in a pattern similar to that of a long electric antenna. The radiation pattern in this mode can also be modeled using dispersed or deterministic models for further accuracy and precision in predicting radio coverage in tunnels.
