Bandwidth Utilization

Basic Communication Systems

Multiple Access Problem: When two or more nodes transmit at the same time, their frames will collide and the link bandwidth is wasted during collision.

Overview Communication is the transfer of information from one place to another. This should be done - as efficiently as possible - with as much fidelity/reliability.

Presentation transcript:

Community Antenna TV System: The CATV system employs a single outdoor unit, with separate feeds available for each sense of polarization, like the MATV system, so that all channels are made available simultaneously at the indoor receiver.

Community Antenna TV System: Instead of having a separate receiver for each user, all the carriers are demodulated in a common receiver-filter system. The channels are then combined into a standard multiplexed signal for transmission over cable to the subscribers.

Community Antenna TV System: In remote areas where a cable distribution system may not be installed, the signal can be rebroadcast from a low-power VHF TV transmitter. Figure shows a remote TV station which employs an 8-m (26.2-ft) antenna for reception of the satellite TV signal in the C band.
