when did telenet launched its first telecom products
Telenet (Belgium) Telenet has offered its residential service since 1997 under the brand name Telenet Internet through the combination of its broadband cable network, which passes some 2.4 million homes in Flanders and a part of the Brussels region. All of the networks through which Telenet offers residential services in Flanders have been upgraded to a two way digital hybrid fibre-coaxial (HFC) standard, and Telenet has direct relationships with all of its Internet and telephony customers.
Communications satellite There are two major classes of communications satellites, passive and active. Passive satellites only reflect the signal coming from the source, toward the direction of the receiver. With passive satellites, the reflected signal is not amplified at the satellite, and only a very small amount of the transmitted energy actually reaches the receiver. Since the satellite is so far above Earth, the radio signal is attenuated due to free-space path loss, so the signal received on Earth is very, very weak. Active satellites, on the other hand, amplify the received signal before retransmitting it to the receiver on the ground.[3] Passive satellites were the first communications satellites, but are little used now. Telstar was the second active, direct relay communications satellite. Belonging to AT&T as part of a multi-national agreement between AT&T, Bell Telephone Laboratories, NASA, the British General Post Office, and the French National PTT (Post Office) to develop satellite communications, it was launched by NASA from Cape Canaveral on July 10, 1962, in the first privately sponsored space launch. Relay 1 was launched on December 13, 1962, and it became the first satellite to transmit across the Pacific Ocean on November 22, 1963.[8]
