Clearwire claims it has transformed Portland into the fastest unwired city in the West, making the city home to one of the first 4G WiMAX wireless broadband services in the world, called Clear. With Clear, consumers and businesses can access the Internet wirelessly, at broadband speeds ─ at home, in the office, around the Portland metro area, and on the go.

Clear's mobile, residential and business plans can be purchased by the day or by the month, and do not require long term service contracts. Home Internet service plans start at $20 per month, while mobile Internet plans start at $30 per month. Additional savings are available for customers that purchase both home and mobile Internet services or that sign up for a two-year service agreement.

Clear broadband delivers up to 6 Mbps download speeds with the Clear residential modem, while mobile Internet customers can expect to receive up to 4 Mbps download speeds.

Clear is currently available in Baltimore, Maryland, and Portland, Oregon, and is developing a multi-year network build-out plan to bring the service to metro areas across the U.S. The Baltimore market currently operates under the XOHM brand, but will be re-branded as Clear in the coming months.

Clearwire currently offers pre-WiMAX Internet services in 46 markets throughout the United States. The company will announce roll-out plans for future markets and upgrade plans for existing pre-WiMAX markets early this year.
