This study of 32 small and medium-sized industrial enterprises explored eight distinct aspects of communication, as appraised by the staff (n 493), and innovative performance, assessed by two indicators: perceived innovation effectiveness and patent statistics obtained from the Patent Register at the National Board of Patents and Registration of Trademarks. The results showed that intraorganizational aspects of communication, such as encouragement of initiatives and critical evaluation of performance, were associated with both indicators of innovative performance. In addition, a participative climate and interaction between the personnel in R&D, marketing and production were related to perceived innovative effectiveness, whereas interaction with clients and other firms related to the number of patents in the organization. The link between communication and innovation was interdependent with the organizational and staff characteristics including the number of personnel, administrative and R&D intensity, the level of vocational training, and the age distribution of the staff.

The 3rd generation cellular systems will offer services with higher bit rates compared to today's networks and therefore for an operator it is of utmost importance to exploit all possible resources to improve the capacity of the radio network. One attractive possibility, already used in most of the 2nd generation networks, is to increase the sectorisation at the base stations, i.e. using 3 or even up to 6 sectors per site. In this paper we demonstrate with simulations and some theoretical derivation how the sectorisation of the base stations influences on the performance (capacity and quality of service) of a WCDMA radio network. In addition the simulator and the modelling of the 3d generations fast power control and soft handover are presented.
