DARP – new receiver technologies boost network capacity:
With a steadily increasing number of mobile radio subscribers having to share limited frequency resources, operators are looking for economical ways to expand their network
capacity. An obvious approach is to use the available frequency spectrum as effectively as possible by employing a reuse factor of 1:1. This, however, involves considerable adjacent-channel interference, which would diminish the desired effect. One solution can be found in a new receiver technology: DARP (downlink advanced receiver performance).

Production test software for GSM reference designs: Universal Radio Communication Tester R&S ® CMU200
With market cycles becoming shorter and the variety of mobile phones steadily increasing, product life cycles have to be optimized at all stages. A critical hurdle is the handover of a product from development to production. To ensure smooth startup of large-scale production after type approval testing, readymade solutions are required, and a test program has to be created while still in the development phase. Using
the R&S ® CMU-TSR10 start-and-go package in conjunction with reference
designs puts convenient ready-made solutions at your fingertips.

Product life cycle management: controlling availability and costs: Integrated Logistics Support
Today, a product is expected to meet not only the customer‘s technical requirements; criteria such as economic viability and availability are increasingly gaining importance. When customers decide to buy a product, it‘s no longer just the purchasing costs that tip the scale – the costs for operation and use are also becoming more and more decisive. Product and system providers meet these challenges by offering product life cycle management (PLM). The PLM strategy is a conceptual solution that sees a product through all its life cycle phases. Correctly applied, it enhances a company‘s competitive position while ensuring customer benefit.
