Internet users want to use IP sharing routers for reducing their cost and managing their terminals easy. Network service providers(NSPs) forced their subscribers pay extra charges to use extra terminal like IP router, since 1998 in Korea. The NSPs asserted that IP sharing routers would harm their networks or would impose extra load on their networks, but they were unable to prove their assertion. Users and manufacturing companies insisted on the legitimacy of IP routers, because the IP router is a kind of terminal for end-users, and as such, the right of selection of an IP router belongs to the user. The interest in and beliefs of the relevant social groups about IP router will be deduced through their interpretation. It draws the technological frame of two social groups, NSPs and IP router-manufacturing companies. The rough struggle between two social groups come from their frames. The article shows how society constructs a particular information technology.

Seamless wireless communication network access technology enables users to guarantee service continuity. Hence, it is necessary for disaster situations in which network service may be interrupted. The Multi-path router is a technology to improve network stability and strengthen field operability, particularly in a disaster environment where network failure can occur by providing high-performance data transmission using multi-communication networks and network security by VPN-based wireless IP. In this paper, a prototype system for an MPR-based wireless communication network was proposed to improve the operation performance for disaster field investigation applications. A comparative experiment was performed on various data transmission performances with the existing single wireless communication network. In addition, another experiment was conducted by measuring the data packet transmission and receiving performance in the existing/new wireless communication system first and then assessing the UDP transmission performance in a single router environment to understand the transmission capability of the new MPR. The experimental results showed that the sending and receiving performance was improved by approximately double that of the existing single wireless communication system. The proposed prototype system is expected to allow users to share and disseminate collected on-site data more quickly and efficiently during a disaster site investigation.
