Clearwire has launched its WiMAX service in Portland, OR. If you own a WiMAX device and live in Oregon’s biggest city, you can experience 4G wireless broadband by purchasing one of the following plans:

• $10 for a 24-hour pass
• $30 a month for 200MB of data
• $40 a month for 2GB
• $50 a month for unlimited data

The WiMAX forum describes WiMAX as “a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL”.
