Clearwire has officially announced the Clear Spot Personal Hotspot today, a portable, battery-powered router that enables any Wi-Fi device to connect to the Clear WiMAX network. Manufactured by Cradlepoint, the Clear Spot connects to the Clear USB modem, creating a personal broadband hotspot for up to eight 802.11 b/g Wi-Fi devices and enabling download speeds of up to 4 Mbps. The device, which we actually expected to be released last month in a puck form factor, looks more like a rectangle and will be available in early April for $149 plus $49 for the Clear USB modem.
