Abstract: The invention relates to a building concept wherein locations of rooms such as bathrooms and kitchens can be easily changed during the lifespan of the building. These rooms may be positioned in several locations almost everywhere in the building and the building may be easily remodeled during its lifespan. The invention is based on providing at least one space part that comprises a floor defining the area of the space part and at least one length of non-load bearing wall bordering the perimeter of the floor and at least one load bearing vertical duct element having at least one vertical cover wall that can be at least partially opened in order to provide access to the inside of the element.

Abstract: An ad-hoc network that includes a plurality of telephones at least one of which is a mobile repeater telephone for establishing a first telephone connection line between a first caller telephone and a first receiver telephone, and for simultaneously establishing at least one second telephone connection line between a second caller telephone and a second receiver telephone. A subset of all the mobile repeater telephones in the network each have its own unique code and a subset of the unique codes are known to a subset of all mobile repeater telephones in the ad-hoc network. The mobile repeater telephones have a software program stored on the processors of the telephones or a database that is accessible by the telephones. The software program includes a geographic map in electronic form of the area of the network and includes data about topography and obstacles and how much the obstacles attenuate the signal.
