This paper provides telecom equipment companies investing in WiMAX (Worldwide Interoperability for Microwave Access) as one of their 4G solutions an overview of the emerging market landscape, the challenges application developers face, and the solutions in use today to make deployment a reality. Wind River maintains that long-term evolution (LTE) and WiMAX will both play significant roles in the evolution of truly broadband wireless networks. Wind River is committed to providing solutions through technology, products, and services that accelerate customers’ business value in terms of time-to-market, cost, and technology leadership, in whichever 4G technology direction they choose to go in. This paper is targeted toward WiMAX, but the underlying Wind River value proposition and products clearly address LTE needs as well.
