TRACER 5045 System Manual Section 2 Microwave Path Engineering Basics 1. LINE-OF-SITE The TRACER 5045 system is designed for operation in the license-free 5.725 GHz to 5.850 GHz industrial, scientific and medical (ISM) band. Radio wave propagation in this band exhibits microwave characteristics which are ideally suited for point-to-point, line-of-sight communications. Line-of-Sight requires that the transmitting antenna and receiving antenna are able to “see” each other, and that the straig

Section 2 Microwave Path Engineering Basics TRACER 5045 System Manual Carrier Wavelength ( λ) The carrier wavelength is the physical wavelength of the main RF carrier being used for communication, and is usually approximated at the center frequency of the band (which is 5787.5 MHz for the TRACER 5045). The carrier wavelength calculations follow: λ = c / f (meters) where c = speed of light (in meters) f = frequency (in Hz) resulting in the following carrier wavelength: 8 5 λ = 3.00 x 10¯ / 5
