We also understand PMR standards and have the tools, core architectures and specialist engineering skills required to develop new protocols or features quickly and efficiently &#8211; keeping your time to market to a minimum. Our test tools also streamline your system and field testing effort.<\/p>\n<p><strong>Straightforward to Integrate<\/strong><\/p>\n<p>Etherstack protocols stacks are written in portable code and isolated from hardware by a well-defined abstraction layer. Integrating a protocol stack onto your platform is a simple process of implementing hardware drivers to support the well-documented interfaces. Candidate areas for DSP optimization are self-contained, making performance tuning simple.<\/p>\n<p><strong>Low Risk<\/strong><\/p>\n<p>A protocol stack is a complex embedded system that must co-ordinate intricate logic, simultaneous interacting events and advanced mathematical computation. It also needs full test support. A wireless standard &#8211; thousands of pages of documentation &#8211; defines the air interface; not how to implement the stack. Consequently, building robust protocol stacks is notoriously risky. Overrun is costly, difficult to fund, and cuts into a product&#8217;s market lifespan and return on investment. Large, specialist development teams can also be difficult to resource.<\/p>\n<p>Etherstack has an unmatched track record of delivering stable, efficient implementations of complex standards such as\u00a0TETRA,\u00a0APCO 25\u00a0and\u00a0DMR\u00a0at fixed price, on time and with warranty included.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/2&#8243;][vc_column_text el_class=&#8221;project-details-txt&#8221;]<strong>High Quality<\/strong><\/p>\n<p>Etherstack protocol stacks are consistent, robust, modular and testable. They are built from a common set of Etherstack Core Services (ECS) design pattern primitives that support an asynchronous event-driven, state-machine based architecture. Interfaces between all design entities are defined, so the stack is easy to understand, maintain and integrate.<\/p>\n<p>Our mathematicians (including internationally recognized FEC experts) go all-out to extract that extra dB of link budget and ensure our implementations are computationally efficient &#8211; reducing component costs and freeing processor resources for other radio functions.<\/p>\n<p><strong>Automated Test Support<\/strong><\/p>\n<p>Given the complex interplay of events in a radio, and the thousands of lines of source code in a stack, verification of functional correctness at all levels is critical.\u00a0Etherstack&#8217;s Lightweight Integrated Test Environment (ELITE)\u00a0provides a common test framework for automated stack testing in simulation and on the target hardware. Full test script libraries are provided, along with a useful debug display tool,\u00a0Etherstack TraceViewer, which allows intuitive at-a-glance analysis of signal transactions and state transitions.<\/p>\n<p><strong>Responsive to Changing Markets<\/strong><\/p>\n<p>An Etherstack protocol stack is a one-off investment. It is highly portable and supplied with all the tools and documentation needed to maintain it, so that it can be used across multiple products.
