AP 2800 and AP 3800 Powering Options - Cisco

1 AP 2800 and AP 3800 Powering OptionsWith each advancein wirelesstechnology, access points are increasingin the numberof radios,processingpower and memory. In 2001 the AP-350 AccessPoint had one GHz radio and processorrequiringonly6 Watts of power. These early PoE access points would fully functionusing the earlier ( )poweringsystemsdevelopedin 1: Early AP-350 used 6 Watts-Newer AP 3800 requires or PoE+Later PoE standardshave since emerged with to 30 Watts at the Power SourcingEquipment(PSE).
