Why do we recommend elevating access points?— Understanding the Importance of Fresnel Zones
Q: What is a Fresnel Zone?
A:Fresnel Zone is a crucial concept named after physicist Augustin-Jean Fresnel, which describes the propagation path and interference of signals in wireless transmission, situated between and around transmitters and receivers. It finds applications in various fields, including optics and wireless communications, aiding in the design of antenna systems for optimal performance. To establish Fresnel Zones, one must first determine the Radio Frequency Line of Sight (RF LoS), the straight line between transmitter and receiver, and then delineate the area surrounding the RF LoS.
Q: How does the Fresnel Zone affect the positioning of Access Points?
A: The Fresnel Zone comprises a series of elliptical areas, with the size of these ellipses assisting in predicting whether r obstacles along the path will cause interference.When the Access Point is positioned at a higher elevation, it can reduce obstruction from ground-level obstacles, ensuring a more stable and reliable wireless connection.
Q: What impact does elevating Access Points have on network performance?
A: Elevating Access Points can enhance coverage, reducing signal weaknesses and dead zones, thereby enhancing the overall performance and stability of the network. This is particularly crucial for locations requiring extensive coverage, such as office buildings, schools, and hotels.
