Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

In ADSL, the OFDM symbol rate across all subcarriers is 4000 symbols per second. Assume that in the downstream direction, 25 subcarriers use 1024-QAM, 50 use 256-QAM, 100 use 64-QAM and 100 use 16-QAM. What is the overall bit rate
QUESTION 25 A microwave data link has been designed to operate at 110,000 symbols per second while encoding 14 bits per symbol. The receiving equipment requires at least a 50 dB signal to noise ratio in order to operate without significant error. At least 55 kHz of bandwidth on the transmission channel are required for the attempted system. The data rate of the designed link will be 1.54 Mbps. If the actual signal to noise ratio is 100 dB, the system could support encoding as many as 17 bits per symbol. There is not enough information given to determine the minimum transmission power needed to make sure an acceptable power level arrives at the receiver. Exactly 16,348 different symbols would be needed to support 17 bits per symbol. If the background noise at the receiver is -50 dBm, the receive power will need to be at least 1 dBm.
