Cover Story 1 Commercially inviable power line communications: reasons why neither proponents nor opponents make concessions Power line communications services, which allow personal computers and information appliances to communicate by just connecting them to outlets such as those in households, stand at a crossroad.  A study group, which is held by the Ministry of Internal Affairs and Communications to assess whether power line communications services are commercially viable, has fallen into an imbroglio.  The ministry plans to draw a conclusion by the end of this September, but the confrontational picture of the proponents and the opponents does not seem to change at all. Proponents: the bottom-line is the operability and speed no less than those of wireless LAN Opponents: safety reference values have to be as strict as of international standards Neutral group: we need more data Differences in "culture" underlie the problem Cover Story 2 Thin clients change drastically as new types are appearing: Eight points to determine the success and failure of installation Thin clients come under the spotlight again as an information leakage prevention.  While users now have more options, including new types that cover the weaknesses of existing products, so are the considerations to be kept in mind when installing them.  In some cases, these options may require redesigning of the network.  Casual installation could cause troubles.  This article introduces eight considerations that determine a successful or failed installation. Consideration: Network boot type consumes a great amount of band Consideration: Diskless PCs are not suitable for mobile use Consideration: In some cases, operation costs may increase Consideration: Installed software may cause security issues
