Antennae, Internet, telephone
Here, too, you should plan room for room, preferably with professional consultation. This assures that even some years into the future the structural prerequisites for computers, telephone, fax, video door answering, satellite systems, etc. are available where they are needed.
Cable TV connection
Usually TV cable is connected underground from the street to the house. To be prepared for future modifications, in addition to electric and telephone cables, it makes sense to provide an empty conduit of 50 mm from the street to the basement. In some areas overhead lines are provided for the house connection.
Details and tips for your specific connections are available from your local cable company. They also generally handle the expert installation.
The larger your parabolic reflector of a satellite antenna (the satellite dish), the less is the risk of poor reception during rain or snow.
- Transmission must be without obstacles between the sender and the receiver in a straight line.
- Transmission employs high-frequency carriers to avoid atmospheric influences.
- The demand today is for smaller satellite distribution systems with 2 to 64 connections and individual receivers and decoders.
- Internet connections for private users are generally possible only with a service contract with an Internet service provider (ISP).
- Connections can be via modem and telephone or ISDN (both antiquated), or via broadband, cable TV provider or mobile phone provider.
- The Internet end device must be connected to the individual computer or the local area network via cable, wireless LAN, Bluetooth or the electric network.
- Which connection is best varies from case to case; not all options are available everywhere.
- For a telephone connection, plan the necessary lines.
- If a wireless LAN is installed, it needs to be protected against outside intruders.
- In addition to telephones, ISDN allows connection of various devices and services (fax, Internet, company computer). With new construction or renovation, it makes sense to route empty conduit from the connection point to all the desired internal extensions.
- Caution: Telecom and antenna lines cannot be routed with three-phase current in the same conduit. Assure a minimum distance is 10 cm or provide a separator.
- Since most devices require a power connection, plan separate circuits; for computer terminals plan an integrated backup power supply.
- Integrate a voltage surge arrester.
Door answering service
- Door bells and normal answering services are normally wired, so do not forget to plan them.
- Video systems for entrance monitoring work with coaxial lines which can be routed with the door answering service lines.
- Wireless video systems are viewed critically in relation to health because of the resulting high-frequency fields.
Plan early how you want to connect TV, Internet and telephone.
