When building ubiquitous architectures some generic quality attributes become fundamental. Whilst applying quality aspects in common architectures is quite difficult, for an environment becoming pervasive is even harder. Mobility, Adaptability, Resource Awareness are features that define such an environment. For their support some qualities like Portability, Scalability, Availability must be reconsidered. Since maximize one usually affects the degree of other, design decisions become highly risky in such a construction. This paper proposes a multidimensional scheme where the space of possibilities for quality properties is depicted. In the scheme areidentified those areas that highlight the conditions to reach the required ubiquitous features and illustrated by samples of current approaches for better understanding. We expect to use this scheme for future classification of adequate features for pervasive environments on architectural approaches.
