A variety of optional 2.4 GHz and 5 GHz antennas are available for Cisco
wireless devices. Antennas should be chosen carefully to ensure that optimum
range and coverage is obtained
.
Each
antenna has different gain and range capabilities, beam widths, coverage, and
form factors. Coupling the right antenna with the right AP allows for efficient
coverage in any facility, as well as better reliability at higher data rates. A
detailed coverage of antennas will be provided later in the course.
