融合通信系统下WiFi门禁系统的实现

传统的由计算机控制的门禁系统需要构建专用的控制网络，并且不能进行局域网之外的无线远程控制；而以IP通信为基础的融合通信，把计算机网络与传统通信网络融合为一体，将数据、音视频融合在一个网络平台上；本文实现的门禁系统，利用IP网络，将门禁和IP融合通信达成一个有机的整体，是一种能实现无线WIFI控制的门禁系统。     

WiFi4EU: Techno-economic analysis of a key European Commission initiative for public connectivity

This paper analyses the WiFi4EU initiative, the measure proposed by the European Commission (EC) to speed up public access to Wi-Fi throughout Europe in the coming years by subsidising the infrastructure. We set out to analyse how these measures are incorporated into the EU policies for building a Gigabit Society and the EC's regulatory tradition, and what the impact is likely to be. This innovative initiative has been drawn up in a climate of uncertainties and delays, and will have an effect upon the network deployments strategies of operators and countries. The article puts all of this into the context of the current European regulation debate and conducts a techno-economic analysis to assess the expected impact of the initiative. We have observed a slight shift towards developmental models in the EC regulatory framework and a step ahead towards multi-level governance. Furthermore, the techno-economic analysis has revealed the limited extent of Community aid and the considerable variability of the equipment deployed and the expenditure involved. We have also highlighted the questionable formulation of the allocation mechanisms, and we have included certain examples or suggestions for improvement.

The response strategies of incumbent mobile network operators on the disruptive potential of public W-LAN in Germany

This paper examines how three incumbent mobile network operators (MNOs) in Germany responded in terms of their strategy to the emergence of the wireless local area network (W-LAN) technology and how they interpreted this potentially disruptive technology in their own strategic context. Additionally, prior empirical results and forecasts on the limited disruptive potential of W-LAN for the German MNOs lacked persuasive firm-level evidence to distinguish the real reason for the presented observations and analysis. So far it was unclear whether the observations were caused by successful response strategies of incumbent MNOs or by the inherent limited disruptive potential of the W-LAN technology. For this purpose case studies of three major MNOs in Germany were performed to assess and compare their respective response strategies. Using the theoretical framework of disruptive technology, the results were evaluated in a cross-case analysis to study how these firms interpreted and reacted to the potential disruptiveness of W-LAN. The results indicate significant differences for the respective MNOs between their perception of W-LAN as a potential disruptive technology, their strategic development processes inside the organisation to understand the potential impact of W-LAN on their respective business model, and to enforce an appropriate response strategy and structural implementation. This incumbent heterogeneity depends primarily on their idiosyncratic strategic and structural context. These findings reveal that the incumbent MNOs in Germany were aware of the disruptive technology concept but did not react in a theory-conform way. However, since W-LAN had a sustaining impact on the MNOs and their response strategies followed sustaining reaction patterns, earlier studies, which show a limited disruptive potential of W-LAN for the German MNOs, are supported.
