The WiMAX Base Station configuration includes support for both the Mobile IP Home Agent and Foreign Agent protocols, including the necessary extensions to support fast hand-offs. This is a key enabler for Voice over IP in the next-generation mobile WiMAX (802.16e) network. The WiMAX Mobile Station configuration includes support for the Mobile IP node protocol.

The Green Hills Platform for Wireless Devices addresses a broad range of applications, from resource-constrained mobile devices and customer premise equipment to mission-critical network infrastructure equipment. Accordingly, it can be configured to use Green Hills Software's ultracompact or advanced routing TCP/IP stacks, both of which are available in IPv4 or dual-mode IPv4/IPv6 configurations.

It also can be used with either of Green Hills Software's royalty-free embedded operating systems: the small and fast velOSity microkernel for resource-constrained and cost-sensitive devices, or the memory-protected INTEGRITY real-time operating system for devices with high security and protection requirements. Scalability and flexibility between TCP/IP stacks and real-time operating systems allows developers to reuse application code across projects and product generations.
