What is e-band frequency?

The e-band frequency is a section of the electromagnetic spectrum with wavelengths ranging from about 1.2 to 0.3 millimeters, which translates to frequencies of 250 to 100 GHz. It is also referred to as the millimeter wave or extremely high frequency band. E-band frequencies offer the potential for high-speed wireless communication and have been used in microwave communication systems, satellite communication, and for 5G cellular networks. They have a limited range due to atmospheric attenuation and are susceptible to path loss and interference from obstacles such as buildings and trees. However, advancements in technology and the use of directional antennas have helped to mitigate some of these challenges.
