Power a Laptop Over The Corporate LAN?
Huh? Is this possible? Connect your laptop to the Ethernet network and you have power.
Power over Ethernet or PoE technology, is the ability of a system to transmit electrical power over standard twisted-pair cable in an Ethernet network.
Low drain devices like IP telephones, wireless LAN access points and webcams are easily powered over the ethernet. The question remains, Can it Power a Laptop?
Low drain, low power consuming laptops should be able to be powered in this way. The standards organization, IEEE have standardized Power over Ethernet in IEEE 802.3af. This standard provides 48 Volts DC at a maximum current of 350mA for a maximum load power of 15.4 watts. It certainly wont be able to power the latest 64 bit Dual Core processor gaming laptops.
This is certainly the way forward. You wouldn't need to plug the AC adapter in whilst at work. No more cumbersome cables. One of the pioneers of this technology is PowerDsine.
The advances in technology should enable any type of laptop to connected to a suitable Ethernet network and recharge the battery.
