Transcript: Evaluating Interference from 5G New Radio (NR) Signals at an Airport Surveillance Radar Prepared By: Mawada khaled belhaj Supervised By: Eng. Yahia ali Electrical and Electronic Department Thank You! INTRODUCTION Outline Objectives INTRO Outline 1 Objectives 5G Overview 2 3 Radar | Airport Surveillance Radar Radio Frequency 4 Case Study 5 Conclusion 6 Objectives To introduce the fifth generation of communication (new radio), and the main principles of RADAR. To study radio frequency and the spectrum of it. Evaluating the interference from 5G (NR) and airport surveillance radar (ASR) using matlab. Objectives Define the airport surveillance radar ASR. 5G Network 5G 5G 5G New Radio 5G Network 5G 5G : In telecommunications 5G is the fifth-generation technology standard for broadband cellular networks 5G Features of 5G technology. 5G has higher bandwidth and can thus connect more different devices, improving the quality of Internet services in crowded areas, and more other features. 5G Frequencies: There are three different frequency bands for the 5G networks; the low and mid-band spectrum at the sub-6GHz range, and the high band at the millimeter-wave, 24–100GHz, frequencies. 5G Frequency 5G New Radio 5G New Radio 5G New Radio, or 5G NR, is a set of standards that replace the LTE network 4G wireless communications standard. A RADAR Radar overview Airport Surveillance Radar RADAR Radar Radar It works by radiating energy into space and monitoring the echo or reflected signal from the objects. It operates in the UHF and microwave range RADAR stands for Radio Detection and Ranging System. An electromagnetic system used to detect the location and distance of an object from the point where the RADAR is placed. The electronic principle on which radar operates is very similar to the principle of sound-wave reflection. Radar Principle The operating principle of a primary radar set. If you know the speed of sound in air, you can then estimate the distance and general direction of the object. The time required for an echo to return can be roughly converted to distance if the speed of sound is known Airport Surveillance Radar An air traffic controller (ATC) radar system used at airports. ASR ASR systems are capable of reliably detecting and tracking aircraft at altitudes below 25,000 feet (7,620 meters) and within 40 to 60 nautical miles (75 to 110 km) of the airport. it is a midrange primary radar used to detect and display the presence and position of aircraft in the terminal area, the airspace around airports. Primary and Secondary Surveillance Radar The air surveillance (ASR) system is an integrated primary and secondary radar system it is located in the airport, connected to the air traffic control center (ATCC), and remotely controlled. The secondary surveillance radar uses a second radar beacon antenna attached to the top of the primary radar antenna to transmit and receive area aircraft data for barometric altitude, identification code, and emergency conditions. Air surveillance (ASR) system. The primary surveillance radar uses a continually rotating antenna mounted on a tower to transmit electromagnetic waves that reflect, or backscatter, from the surface of aircraft up to 60 nautical miles from the radar. Radio Frequency Introduction Radio State-of-the-art in Spectrum Sharing boundary Introduction Radio frequency spectrum is a scarce natural resource that is utilized for many services including surveillance, navigation, communication, and broadcasting. Radio frequency spectrum Recent years have seen tremendous growth in use of spectrum especially by commercial cellular operators The US spectrum regulatory bodies are working on an initiative to share 150 MHz of spectrum, held by federal agencies, in the 3.5 GHz band with commercial wireless operators. This band is primarily used by radar systems that are critical to national defense. Spectrum sharing is a promising approach to solve the problem of spectrum congestion as it allows cellular operators access to more spectrum in order to satisfy the ever growing bandwidth demands of commercial users. State-of-the-art State-of-the-art in Spectrum Sharing Waveform Shaping Waveform Design Interference Modeling Channel Modeling Resource Allocation Evaluating Interference Case Study CASE Background First scenario Second scenario Third scenario Fourth scenario from 5G New Radio (NR) Signals at an Airport Surveillance Radar Background Background The 5G current spectrum lies around 3:5 GHz and future 5G and 6G systems will also operate in mmWave bands (near 26 GHz and above 60GHz), falling outside the current aviation spectrum, and therefore having the promise of low interference with existing ATM signals Innovative technologies - not traditionally specific to Air Traffic Management (ATM) domain - are of increasing interest in order to support, in a sustainable and efficient way, the various Communication, Navigation, and Surveillance (CNS) requirements in airport areas.

Transcript: Nobody knows babies like we do! Quality products . Good Customer service. Every Kid really loves this store.. BABYLOU ABOUT US About Us BabyLou was established in 2004. It has been more than a decade since we started, where we have ensured to take care of every need and want of every child and infant under one roof, true to the caption “NO BODY KNOWS BABIES LIKE WE DO”. Our benchmark is to provide 100% customer service and satisfaction and continue to deliver the same with a wide range of toys, garments and Baby Products. Play and Create We Are Best 01 02 03 Block games Building Blocks help Kids to use their brain. PLAY TO LEARN in Crusing Adventures Our Discoveries Enjoy a sunny vacation aboard a luxury yacht with the LEGO® Creator 3in1 31083 Cruising Adventures set. This ship has all the comforts you need, including a well-equipped cabin and a toilet. Sail away to a sunny bay and take the cool water scooter to the beach. Build a sandcastle, enjoy a picnic, go surfing or check out the cute sea creatures before you head back to the yacht for a spot of fishing. Escape into the mountains Disney Little Princes in Also available for your Babies..... Also... Out of The World… Our reponsibility BABYLOU…. Our Responsibility All children have the right to fun, creative and engaging play experiences. Play is essential because when children play, they learn. As a provider of play experiences, we must ensure that our behaviour and actions are responsible towards all children and towards our stakeholders, society and the environment. We are committed to continue earning the trust our stakeholders place in us, and we are always inspired by children to be the best we can be. Innovate for children We aim to inspire children through our unique playful learning experiences and to play an active role in making a global difference on product safety while being dedicated promoters of responsibility towards children.
