antenna in networking?

Answer 1

Please elaborate, what is the question? In wireless networking, the antenna is what receives and transmits electromagnetic waves in from and out to the air/atmosphere. They come in a variety of shapes and sizes, which depends on the gain (power) of the antenna, the frequency range (like 2.4GHz versus 5GHz), and the radiation pattern (like omnidirectional versus a dish antenna) and the polarization, where almost everything in wireless networking uses vertical polarization.
