Green Hills Software Inc. has added WiMAX support to the Green Hills Platform for Wireless Devices, accelerating the development of both WiMAX mobile and base station devices.

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.
