Antennas 101

Antennas 101

The antenna has two basic functions. On the receiver side, it converts electromagnetic energy into voltage, which gets processed and converted to digital data. On the transmitter side, the antenna transforms voltage into electromagnetic energy that radiates into the air. Complex modulation schemes carry the digital data streams over radio signals.

Just how well your antenna pulls off this bit of magic determines whether your users get connected and, if so, how fast the system performs. If your antennas don't radiate properly for your facility, your WLAN interfaces will drop their data rates to adjust to the antennas' lower signal level. And your performance goes down the tubes.

The right antenna maximizes your coverage and makes sure your WLAN transmissions stay inside the building instead of sending signals out to the parking lot.
