Clearwire Goes For $400 Million IPO

"Clearwire’s decision to tap the public markets underscores the fact that setting up big nationwide WiMAX network in the US is going to be very very expensive. In-Stat, estimates that it would take a total of $3 billion to set-up a national WiMAX network in the US. Clearwire was started back in 2003, and uses pre-WiMAX gear developed by its NextNet Wireless arm to provide download speeds of 1.5 Mbps."
