The PowerDsine 4001 Hub is a single channel system developed specifically to support the typical scattered architecture of wireless LAN and Bluetooth access points in an Ethernet environment. The PowerDsine 4001 Hub mid-span device, which connects between any standard 10/100BaseT Ethernet port and wireless LAN access point or base stations, enables a unified supply of data and power to be delivered through a single line. The PowerDsine 4001 sends power over the unused portion of the commonly used standard Category 5 twisted pair (LAN) cables. Ideal for the SOHO market, the PowerDsine 4001 provides the same features as PowerDsine multi-channel solutions, while offering the significant cost benefits of supporting single port applications. The PowerDsine 4001 features plug-and-play convenience with a unique line sensing capability that identifies Power over LAN Enabled devices and prevents the distribution of power to those devices that are not enabled.
