Choosing the right access point
Cisco Catalyst 9120i and Cisco Catalyst 9120e (external antenna version)
Use cases for 9120i
● Aesthetics (carpeted areas)
● No additional antenna costs
● Less items to install
● Sometimes better for high ceilings
Use cases for 9120e
● Industrial applications requiring a higher temperature
● External or directional antennas are desired (inside/outside use)
● Longer range or need to focus energy
● Dual 5-GHz (covering different cell areas) directional/omnidirectional
● Use of legacy single-band antennas or different 2.4-GHz/5-GHz cells
