At the most basic level, WiMAX supports mobile, fixed and nomadic wireless applications. A mobile application provides communication while the user is in transit. A good example is a business traveler who communicates while on a train. The Sprint Xohm service provides Internet access while moving at high speeds using WiMAX technology.
Fixed wireless applications often provide last-mile connections in rural or underdeveloped areas that do not have Digital Subscriber Line (DSL), Hybrid Fiber-Coax (HFC), or other last-mile wired infrastructure. Enterprises can either purchase fixed WiMAX technology for use in their own private network (e.g., a point-to-point wireless connection between two buildings) or can purchase fixed WiMAX service from a wireless Internet service provider. Towerstream provides fixed, high-speed WiMAX access.
