WiMAX technology offers a perfect next-generation wireless solution. Unfortunately, it requires a completely new infrastructure, so it is best for greenfield deployment.

You can expect to see WiMAX technology in greenfield networks trying to sell high-speed connectivity (for example, high-speed Internet access in rural networks).
