Data communication

Q. Criteria for cable selection for data transmission

A. The bandwidth of various cables, such as coaxial, twisted, and so on, varies. As a result, we select cables based on their bandwidth.

Q. 2.4g WIFI doesn't work on dual broadband router whereas 5g network works fine

A. 5 GHz WiFi frequency provides more bandwidth and channels to users.

Wireless protocol used to communicate for a short distance

What will be the baud rate of a communication channel that can transfer 20 symbols in 5 seconds?

Wireless channels are more prone to bit error than wired channels

What are the essential elements of linear array detector signal processing, and what are their functions?

Is QAM the best choice for efficient bandwidth?

A. Bandwidth of QAM = 1*R baud, where R = number of symbols per second
