Welcome to the website of Jens David Consulting. We are a leading company in the area of Communications Engineering, Digital Signal Processing and Embedded Systems. Our mission is to design custom-made to your specification IP blocks, complete receiver and transmitter modules as well as other physical layer components. We are experts in the domain of Baseband Signal Processing. Our broad compentence, looking back on 15 years of experience, allows us to support you in the whole process of product design, including the more complex tasks such as conception, specification, system architecture/analysis, algorithm design/performance assessment and verification, where a comprehensive understanding of the overall system including the RF component is mandatory.
Due to popular demand we also expanded our business to the area of iPhone system design in the last months.

This system extension allows to use the iPhone with RSAP-enabled car handsfree sets. Supported are iPhone 3GS and iPhone 4 (the old model without "S" only) running iOS versions 4.x to 6.x. Continuation of development has ceased now and is unlikely to continue. We ask you to stop inquiring about that, because answering those inquiries costs a lot of time. Possibly this website helps you for newer iPhones.
It is a very useful thing to have a backup copy in your network whenever your primary data goes south. Unfortunately, Cloud services for this purpose are usually ruled out due to security considerations and Time Capsules due to high power consumption and total cost of ownership. In this report I explain how to leverage your -- usually always active -- Fritzbox to perform this additional task. Just like with the Cloud solution your data will always be accessible via (W)LAN or even securely via VPN and Internet. Using a simple trick you can force Time Machine to save and transfer your data in an encrypted way.
