Radio scanning makes the Ericsson W3x capable of sensing other access
points of the allowed channel.
3.3 USB Interface
The Ericsson W3x includes one USB 2.0 Host Controller with one external
type A connector supporting low, full, and high speed. The USB interface
supports one high power device hence the maximum power consumption of
a device is 500 mA.
Maximum practical cable length for USB is 5 m.
3.4 Ethernet Interface
The Ericsson W3x includes a Fast Ethernet switch with four (4) external
LAN 10/100BaseTx ports (female RJ45) for connection to Ethernet devices.
Each Ethernet port supports rate auto-negotiation and MDI/MDIX auto-
detection. The MDI/MDIX auto detection allows the user to plug in either a
straight or crossed Ethernet cable.
Maximum cable length for Ethernet is 100 m.
