PoE Technology In The Future IEEE802.3at (PoE+)
The enhancement of the PoE+ is to increase the amount of power that can be supplied from PSE to the PDs, via the Cat-5, Cat-5e, Cat-6 unshielded twisted pair wiring.
The new specification attempts to bring the power supplied up to at least 24 watts. (draft 3.0 proposed; 30W in draft 2.0)
New standard may have approve by year 2009 with the enhancement mentioned above.
With new standard apply there will have more PD available for PoE applications, eg: Security IP Camera with pan/tilt/zoom capabilities, door controllers, POS terminals, videophones and dual-band wireless access points….etc.
