Clearwire Corp will be launching a new WiMAX (Worldwide Interoperability for Microwave Access) product: a prepaid solution that will compliment it's existing contract basis and month-to-month basis products. Clearwire offers it's 4G internet service to approximately 56 million people (49 markets) through relationships with Sprint, Comcast and Time Warner Cable. Clearwire has announced it's plans to expand its 4G coverage across the US, and this new market segment, pre-paid internet, will certainly expand it's subscriber base. The company is looking to leverage pre-paid data in both the 3G and 4G markets. It's major competitor, Verizon, has announced plans to make it's contract data plans more attractive: 5GB of 3G is $60 per month with contract but $80 on a prepaid plan.
