Voices from the Field: Using Enea OSE to ensure real-time characteristics in an LTE terminal device.

In this interview, we are talking to Mr. Zhang, a VP for Research and Development at a company that develops LTE  terminal devices. In the design, Enea OSE is used on an ARM cluster and Enea OSEck on DSPs.

Enea: What is your role in the organization?

Mr. Zhang: I am the VP for Research and Development. Since 2016 we have been developing an LTE terminal device for Private Mobile Radio.

Enea: What is your general impression as a user of OSE?

Mr. Zhang: OSE delivers very high performance combined with deterministic real-time characteristics. This is exactly what we were looking for when selecting OSE as the operating system for the LTE terminal device. OSE has a rich set of APIs and protocol stacks for networking, and during the product development, we also benefited from the strong debugging tools that accompany OSE.

Enea: How does OSE fit technically into your project?

Mr. Zhang: Besides the hard real-time requirements, the most important requirements for the LTE terminal device were: POSIX support, support for networking protocols, and support for USB. OSE provides a rich POSIX API, and a large range of network protocols, and USB support – this combination adds strong value to our product.

Enea: What technical challenges do you solve with OSE?

Mr. Zhang: Our application has stringent real-time requirements. Fortunately, these requirements were easily solved with OSE. The USB support was also important. The USB stack is a third-party product that initially caused us some problems, but Enea helped to quickly solve the issues. The support has been great ever since.

Enea: Are you satisfied with the design help and on-site support that you have received from Enea?

Mr. Zhang: We are very pleased with the technical support services from Enea. Enea has a worldwide support organization with local teams. The local team manages all our requests with short response times. Our experience of Enea R&D is very positive – despite the difference in time zones – all issues were handled in a timely and efficient manner.

Enea: How is your product portfolio going to evolve?

Mr. Zhang: We are now developing our first LTE terminal device, which soon will be ready for launch. We plan to extend the portfolio with additional models –with more functionality including additional protocols applicable to new markets and use cases. For the next generation terminal devices we plan to use processors with more cores – which in combination with OSE – will make our product portfolio even more impressive!

Enea: Thank you, Mr. Zhang!
