Signal Coverage Case Of Eight Bands All-network Booster
ATNJ Mobile Signal Repeater.pdf   Time: Dec.28 2022 Address: Tomorrow club, Jiangmen City, Guangdong Province Requirements: Calling and data signal coverage of all networks     Tomorrow Club is a newly-decorated bar. The bar is luxuriously decorated and the exterior walls are decorated with steel plates, making the mobile phone signals inside the bar, whether it is China Mobile, China Unicom, or China Telecom communications, the call and Internet signals are very poor, even it’s a very hard to send or receive message for wechat. The renovation of the bar is completed and the opening is imminent. It is imminent to solve the problem of the three network mobile phone signal inside the bar. Because the interior area of the entire bar lobby is about 500 square meters, 8-band equipment is used for customers, and two ceiling antennas are promoted as a lobby coverage solution. The advantage of using this solution is: the China Mobile low-frequency call GSM900 and high frequency call DCS1800, China Telecom call CDMA800, and China Unicom 3G call WCDMA2100 are amplified and covered to effectively solve the needs and problems of three-network calls.   At the same time, the 4G Internet access signals FDD-LTE1800M of China Unicom and China Telecom, as well as China mobile 4G Internet frequency bands D, E, and F were automatically locked, which were effectively amplified to solve the needs and problems of these three networks.   Besides, the biggest advantage of this 8-band all-network booster is that no matter when the operator adjusts these base stations, it will not affect the user ’s three-network call and three-network data experience, because all existing frequency bands are all covered.   The designed scheme is shown in the following figure,   Use two LPDA antennas to receive wireless. One is to receive and transmit CDMA800M, GSM900M, DCS1800M and WCDMA2100, and the other antenna is to receive and transmit FDD-LTE 1800M and TDD-LTE1900M / TDD-LTE2300M / TDD-LTE2600M (the three-way signal D, E, and F bands for mobile 4G are automatically selected by the device).   Wiring Construction: After the completion of the construction, test that the signal strengths of the first channel are shown below: The first channel has a full output power as around +17dbm.   The signal strengths of the second channel are shown below: 4G FDD-LTE1800M of China Unicom and Telecom has a full output power in second channel: +17dBm.   The mobile 4G channel automatically locks the F-band TDD-LTE1900M with the best signal strength + 17dBm full power output.   In the normal working state of each frequency band of the equipment, the signal strength test of each frequency band in the hall is as follows:   The signal strength of the three major operators, whether it is calling signal or data signal, has reached full bar. In addition, when a lot of people test the calling and data signal at the same time in the bar, the signal strength keeps stable to meet the demands.   Dot test of China Mobile and China Unicom signal was performed, it shows the signal coverage and signal strength are balanced. As shown below, Summary: In case of using 8 bands full-network booster, there is no need to consider the working frequency, because all frequency of signal operators are included. Therefore, when design the construction plan, we only need to consider the coverage area, range and required antenna and the length of cables.   It is best to install two LPDA outdoor antennas in an upside down position, pointing to different directions, so that the six sets of values on the screen of the device all work to the maximum output value.
KFC Signal Coverage
ATNJ Mobile Signal Repeater.pdf Time: Feb.01, 2023 Address: KFC Restaurant ( CaiDe Town) Requirements: 4G signal coverage of China Unicom and China Telecom   KFC Restaurant (CaiDe Town) is located on the first floor of Caide Town, CaiTian Road, Futian District, Shenzhen. The location of a KFC restaurant is usually in the center of various business districts, where are usually covered by great signal of the three major signal operators.   After the site survey, we found the signal of China Mobile is very good, and no need to consider China Mobile signal. However, 4G signal of China Unicom and China Telecom are weak on the checkout counter, kitchen, corner, and office. The reason is that China Mobile had signal coverage inside of the building. Therefore, people could only receive China Unicom and China Telecom signal from outdoor base station. What’s more, as there is a building in the front of KFC restaurant, it’s normal to have weak signal of China Unicom and China Telecom in KFC restaurant.   To solved the mentioned weak signal problem, we only need to aim at the exact signal frequencies and make signal coverage at the following positions.     Signal survey result as follows,   According to the above signal data, we could tell that China Mobile had a great signal distribution inside, but China Unicom and China Telecom not. Therefore, we need to transmit the outdoor signal of China Unicom and China Telecom to indoor, then amplify it.   Scheme Design According to the signal demands and the site survey, we use a high-power repeater with six indoor antenna to amplify signal in the checkout counter, kitchen, corner, and office. Topology picture as follows,   Wiring and construction Considering the clients flows and business time of KFC restaurant, the construction time was arranged to avoid the rush hour, and the whole construction is noiseless and dust free. Besides, the construction of kitchen was arranged after 21:30.   Except the indoor antenna in lobby, all the other antennas are installed into the ceiling without any exposure. Also, the outdoor antenna was installed below of the signboard, where won’t be look strangely.   Effect Test After signals are amplified, the signal strength is tested as follows,   Except no change on China Mobile signal, there are a great improvement of China Unicom and China Telecom signal. Especially the delivery clerks could have a better experience to receive takeout order and arrange delivery. The signal coverage offers a better signal experience for client and KFC staff.   Summary As KFC restaurant is usually covered by great signal of the three major signal operators, the signal problems are more likely that some frequencies are not covered. Therefore, an accurate site survey are necessary, then we could use a suitable repeater with correct frequency to amplify the specific signal to meet the demands of signal coverage.   Besides, as it’s a KFC restaurant, we have to consider the construction time when it won’t affect the business with easiest construction method.
Counter-UAV Market Research Report
     On 23rd Jan, 2025, according to the northeast. newschannelnebraska website, a recent research report entitled "Anti-UAV Market Research Report" was reported by the northeast.newschannelnebraska website. The report was divided into targets (UAVs, cruise missiles), detection and tracking systems (RF detection, acoustic sensing, optoelectronic sensors), confrontation (kinetic confrontation, directed energy weapons, network confrontation), platforms (land-based systems, sea-based systems, airborne systems), applications (military, law enforcement, homeland security) and regions (North America, Europe, South America, Asia Pacific, Middle East and Africa). It reveals the rapid expansion and changing dynamics of the anti-UAV market by 2032 and provides insights into the key drivers, challenges, and opportunities that shape the anti-UAV field.      The counter-drone market is expanding as global security concerns continue to rise, especially in regions vulnerable to drone threats. Drones, traditionally used for recreational and commercial purposes, are increasingly being used for illegal activities such as smuggling, espionage, and terrorism. This growing threat has prompted the need for advanced systems that can detect, track, and eliminate these aerial threats. The ability to counter drones effectively is a key factor in protecting important assets such as military facilities, government buildings, airports, and borders. Furthermore, as drones become more sophisticated and difficult to detect, the demand for innovative counter-drone technologies is expected to increase.      The market is expected to witness strong growth in the coming years, driven by factors such as advancements in drone technology, increasing use of drones in military and commercial applications, and high focus on national security. Governments and defense agencies are investing heavily in counter-drone technologies to prevent potential attacks and protect their airspace. Furthermore, with the continued adoption of drones in the commercial sector, the need for protective countermeasures is becoming more pressing.      The anti-drone market can be categorized based on the type of target, with the major segments including unmanned aerial systems, drones, and cruise missiles. Drones are commonly used in military and civilian applications and are popular due to their affordability, versatility, and ease of use. However, their widespread adoption has also contributed to the growth of anti-drone systems due to their potential for misuse in malicious activities.      Drones, as a subset of unmanned aerial vehicles (UAVs), are increasingly being used for commercial applications, including surveillance, delivery services, and photography. Despite their positive uses, drones can also be used for harmful purposes, such as illegal surveillance, terrorism, and even weaponized attacks. This has led to the need for reliable countermeasures that can detect, track, and neutralize drones to protect sensitive areas.      Cruise missiles are another important target for the counter-UAV market, posing a significant threat to military and civilian infrastructure. These high-speed weapons are designed to strike with precision at long ranges, making them a priority for countermeasures, especially in defense applications. With the continued development and deployment of cruise missile systems around the world, there is an increasing focus on counter-cruise missile technologies and systems.   A key component of any counter-drone system is detection and tracking technology, which enables authorities to identify and monitor drones and UAVs before they pose a threat. The main detection and tracking systems include radio frequency (RF) detection, acoustic sensing, and electro-optical sensors.     RF detection is one of the most widely used technologies for detecting drones. The system works by identifying RF signals emitted by the drone's communication system. By analyzing these signals, the RF detection system can determine the drone's location and movement, allowing operators to track and eliminate the threat. RF detection systems are effective in a variety of environments, providing long-range detection capabilities and real-time tracking.     Acoustic sensing is another method used to detect drones and UAVs. The system uses microphones to pick up the unique sounds produced by the drone's motors and rotors. Acoustic sensors can help determine a drone's location by analyzing its acoustic signature. The technology is particularly useful in situations where RF signals may be difficult to detect, such as in dense urban environments or areas with high levels of electronic interference.      Electro-optical sensors, such as infrared cameras and visible light sensors, are used for the visual identification and tracking of drones. These sensors detect the heat signature or light reflections of drones, providing detailed imaging that can be used to monitor and assess the situation. Electro-optical sensors are particularly effective in low-light conditions, such as at night or in areas with limited visibility, making them an essential component of a comprehensive counter-drone system.   Once a drone is detected and tracked, countermeasures are required to eliminate the threat. The anti-drone market is segmented based on the type of countermeasures used, with the main categories being kinetic countermeasures, directed energy weapons, and cyber countermeasures.     Kinetic countermeasures involve the use of physical force to destroy or disable a drone. These countermeasures typically involve intercepting the drone with projectiles or other physical means. This may include the use of high-speed projectiles, nets, or even trained birds of prey to neutralize the drone. Kinetic countermeasures are often used in military and law enforcement applications where precision is critical.     Directed energy weapons, such as lasers and microwave systems, are a rapidly growing class of countermeasures in the counter-UAV market. These technologies use concentrated energy to disable or destroy drones by damaging their electronics or structure. Directed energy systems are particularly effective in neutralizing drones at long ranges, providing a scalable solution for protecting airspace and critical infrastructure. The development of directed energy weapons for counter-UAV applications is one of the most exciting innovations in the market.     Cyber ​​countermeasures involve controlling or disabling a drone's communication systems through electronic warfare techniques. These systems can hack into a drone's communication network to override its controls or force the drone to land safely. Cyber ​​countermeasures are increasingly being recognized as a viable solution to disrupt malicious drones while minimizing collateral damage to the surrounding area.   Counter-UAV systems are deployed on a variety of platforms, including land-based, sea-based, and airborne systems. Each platform offers unique advantages depending on the operational requirements and the environment in which the system is deployed.      Land-based systems are the most common and versatile form of counter-drone technology, deployed on the ground at strategic locations such as military bases, government buildings, and critical infrastructure. These systems are designed to protect large areas, provide perimeter defense, and secure the airspace from unauthorized drones.     Sea-based systems, on the other hand, are designed to provide protection for ships operating in open waters. These systems are essential to protect naval assets from potential drone threats, which can be used for surveillance, smuggling, and even attacks. The growing importance of maritime security has led to increased investments in naval counter-drone systems.     Airborne systems are deployed from aircraft to provide air defense against drones, particularly in situations where land-based or sea-based systems may be ineffective. These systems can cover vast swaths of airspace, making them ideal for use in high-risk areas or areas with limited ground infrastructure.     SDR boards are poised to play a significant role in the counter-drone market. With the increasing complexity and agility of drones, traditional countermeasures are facing challenges. SDR boards offer a flexible and adaptive solution by enabling the rapid development and deployment of advanced signal processing techniques for detecting and mitigating drone threats. Their versatility and reconfigurability make them well-suited for countering evolving drone technologies effectively. As the demand for innovative and efficient counter-drone systems grows, SDR boards are emerging as a crucial technology driving advancements in this critical security domain.
