R&D Resources and Development-Related Standardization with Strong Network Effects - The Case of 3GPP and Telecom Firms

This paper studies the interdependence between R&D resources and standardization performance in development-related standardization settings under strong network effects. Standardization performance is viewed as the firm’s involvement in the change process of standards as a result of the business processes of standardization. We utilize a sample from the 3GPP change request database to study f

User Centered Design of Non-Visual Audio-Haptics

The following article reports result from an extensive study with 25 blind users from Italy and Sweden performed during the summer 2001. The tasks reported here test recognition of geometrical objects, recognition of VRML objects, mathematical surfaces and navigation in a traffic environment. The outcome of these tests show that blind users are able to handle also quite complex objects and environ

Higher order MIMO outdoor-to-indoor measurements using repeaters

In this paper we present results from a outdoorto-indoor MIMO measurement campaign where we study the effect of repeaters on singular values, spatial richness, capacity,and delay spread distributions. We present results from different repeater scenarios such as, e.g. different outdoor/indoor repeater deployments with ngle/dual polarized antennas. The measurements show that repeaters significantly
