Best Practices for Wireless Links Seminar

• Luis Ortega, Beagle Latinoamérica's channel manager, welcomes attendees to this seminar on best practices for a wireless link developed in collaboration with regional distributors using the Wiki Forum.
• The seminar is approximately one hour long and covers essential basics, focusing on key principles to help attendees better understand.
• The presentation material will be shared at the end for those who cannot see it.
• Some updates have been made for those who may have attended a previous presentation on the same topic.
• Topics to be covered include radio frequency fundamentals, channel selection, line of sight, and antenna recommendations for point multipoint systems.
• A radio link is a wireless transport mechanism capable of transmitting data between two points.
• 802.11ay uses a WDS (Wireless Distribution System) architecture that enables end-to-end transparency but requires significant hardware and software processing resources.
• 5GHz and 60GHz radios provide higher capacity but less range due to signal loss, affecting propagation and susceptibility to interference and noise.
• When making modifications to frequency, power, or antenna gain, the cost-benefit ratio should be considered.
• Understanding terms like base station, CP, and troncal and their functions is important for deploying effective wireless solutions.
• The base station is a point multipoint architecture, with a sectorized design, allowing for flexible deployment and scalability.
• The CP (Client Premises Equipment) is the final connection point between the provider and the end user, with various names depending on the network.
• The troncal (or backbone) is a crucial element, usually a point-to-point link, ensuring connectivity and availability for many other devices.
• Understanding the role of frequency and how it affects communication is essential for optimizing wireless networks.
• Terms such as base station, CP, and troncal have specific functions and can be referred to as "equipo CP," "equipo estación base," or "enlace troncal" depending on the context.
• In wireless projects, it's often necessary to go directly to the troncal to maintain good network performance.
• The troncal provides more capacity and processing power to handle increased communication traffic and stress.
• When planning your wireless network, consider the type of devices and applications you are using, as well as the anticipated growth of your network.
• Knowing the differences between products and their specific capabilities allows you to choose the best solution for your needs and budget.
• Understanding the fundamental principles and technologies of wireless networks is essential for designing, implementing, and maintaining effective and efficient wireless solutions.
• The Wiki Forum provides a collaborative platform for exchanging knowledge and best practices, enabling the wireless community to improve and evolve together.
• The seminar covers the key concepts of wireless networks, including the fundamentals of radio frequency, channel selection, and line of sight.
• Real-life examples and use cases are provided to illustrate the theory and practical applications of wireless network technology.
• The presentation also covers antenna recommendations, including the importance of frequency selection, antenna gain, and power considerations.
• The seminar provides valuable insights and practical knowledge for anyone involved in wireless network design, implementation, or management.- Se puede usar frecuencias extendidas en algunos productos, pero hay que tener en cuenta las regulaciones de cada país.
• La frecuencia más apropiada para la mayoría de proyectos es la de 5 y 6 GHz, libre en la gran mayoría del territorio.
• Punto a punto: capacidad exclusiva entre dos elementos, failure-prone if line of sight is not clear, requires direct line of sight.
• Punto multipunto: capacidad compartida, suitable for traffic of services or demand-based services like the internet.
• Punto multipunto can also handle dedicated traffic or capacity-specified traffic.
• Línea de vista: important for successful transmission, affects range and quality of link, depends on frequency and height of antennas.
• Obstacles such as buildings or mountains can cause attenuation, reflection, or rejection of radio waves.
• Line of sight calculation: requires specialized tools to estimate the propagation distance and height of the antenna above ground level.
• Verification of line of sight: first step in selection of equipment, using software such as Hata, which can simulate and determine the feasibility of the link.
• Choosing a product: not important at this stage, as long as it operates at the chosen frequency, the line of sight must be verified first.
• Working frequency: affects the required line of sight distance, the lower the frequency, the greater the distance required.
• Equipment placement: crucial for successful transmission, must be at an appropriate height to establish line of sight.
• Commonly used frequency bands: 2.4, 5, and 24 GHz, each with different requirements for line of sight and propagation distances.
• Hata software: can be used to verify the line of sight, determines the maximum height of obstacles and the required antenna inclination.- Se trata de un software que ayuda a verificar la viabilidad de un proyecto de comunicaciones ante obstáculos y alturas para establecer enlaces.
• El software permite simular puntos singulares y multipuntos para hacer pruebas de línea de vista y verificar obstrucciones.
• El software funciona principalmente con topografía cartesiana basada en terreno, no calcula vegetación o construcciones adicionalmente.
• Existen tres familias de productos recomendadas: Jay Fiver, Max, y otras.
• La familia Max ofrece una alta capacidad de espectro y capacidad de paquetes por segundo, pero tiene una latencia mayor.
• La familia Jay Fiver procesa paquetes por hardware y mantiene casi toda su capacidad incluso con tipos de arquitectura de paquetes pequeños, y es recomendada para troncales.
• La modulación es la complejidad de la onda y más alta es la capacidad, pero si se deforma se pierde rendimiento.
• Secuencias de modulación y arquitectura como 12 bits y Schmitz 8 mil 624 se utilizan.
• Por lo general, se recomienda no usar toda la potencia y evaluar la modulación para optimizar el rendimiento.
• Cada familia de productos tiene recomendaciones de potencia específicas para las diferentes modulaciones.
• La potencia se configura de forma directa en el equipo y la capacidad se combina con la de la antena para desarrollar la propagación de la señal.
• Los menos de evm corresponde a la recepción de la señal y se refiere a milivatios.
• Los radios pueden transmitir con fuerzas muy altas (probablemente sobre 8.000 o 10.000 milivatios) y las capacidades de recepción son muy pequeñas.
• El software puede trabajar con potencia directa en la actualidad.
• Antiguamente, se utilizaba mucha potencia debido a ondas menos complejas, pero hoy en día buscamos más capacidad.
• Las potencias se ingresan de forma directa en la mayoría de equipos y la potencia máxima varía según el modelo.
• En el caso de Fiverr, la potencia se ingresa también de manera directa en las últimas versiones del software.
• Las antenas tienen una capacidad específica y se combina con la potencia para desarrollar la propagación de la señal.
