PROBLEM TO BE SOLVED: To provide an information transmission system with an inexpensive communication cost without needing a high performance server and without having to lay a LAN cable at the time of constructing a LAN. SOLUTION: Hub communication terminals A and G in LANs 2 and 3 are connected to a trunk network 1. The hub communication terminal A automatically transmits information received from the trunk network 1 to other communication terminals B and D in the LAN 2. The hub communication terminal G automatically transfers the information to another communication terminal H in the LAN 3. The communication terminal B further, automatically transfers the information another communication terminal C. The communication terminal D automatically transfers the information to communication terminals E and F. The communication terminal H automatically transfers the information to a communication terminal I. Small power radio or power or power line carrier is used for information transfer. |
