One of AT&T's core 4G LTE bands is band 2, which operates at 1900 MHz. If we made a quarter wave monopole antenna designed for this band, what should the length of the antenna be? AT&T also owns band 5 (850MHz), also used for LTE. Which of these two bands (band 5 vs band 2) would provide higher data rates, and why? Comparing GHz vs Khz frequency radiation for radio communication, what is one 1 disadvantage of the higher frequency...

Learning Goal: To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol A (lowercase Greek "lambda"), is usually measured in meters. Every wave also has a frequency, which is the number of wavelengths that pass a certain point during a given period of time. Frequency, given...
