Consider a CSMA/CD network that transmits data at a rate of 100 Mbps (108 bits per second) over a 1 km (kilometer) cable with no repeaters. If the minimum frame size required for this network is 1250 bytes, what is the signal speed (km/sec) in the cable?
Assume that a channel occupies a bandwidth of 110 kHz. We need to combine eleven channels into a link with a bandwidth of 1.26 MHz, from 1 to 2.26 MHz with 5 kHz guard band. Show the configuration, using the frequency domain.
Suppose, four users with 150khz bandwidth are multiplex and use 10kHz for the guard bands, then what should be link bandwidth. * 620 630 640 600 Suppose, there are two channels to multiplex, one bits from each source and use TDM with 180Kbps and 190Kbps. Pulse stuffing is allowed if requires. What is the size of a frame in bits? 1 2 4 Not available
Explain it properly Select the three true statements from the following list. Select one or more: MIMO and frame aggregation are techniques used in recent Wi-Fi standards for increasing capacity. The 2.4 GHz ISM band runs from 2.4 GHz to 2.4835 GHz. In Wi-Fi networks, the CSMA/CA protocol can only be used when RTS and CTS frames form part of the procedure. As the frequency of a radio wave increases its data carrying capacity decreases. A wireless access point is an essential component of a Wi-Fi ad-hoc network. If five users are connected to a wireless network that offers a maximum data rate of 54 Mbit/s and a throughput of 60%, the typical practical data rate available to each user in ideal conditions will be less than 7 Mbit/s. A parity check is an example of an error correction code.

What is the delay of sending a data file from a source station to a destination station? Suppose that the length of the data file is 2 Mbytes and the bandwidth of the channel is 1600 bps, and the network link between the sender and receiver is 20000 Km and the speed of the light inside the link is 2x108 meters/second? Assume that the delay is composed of only transmission time and propagation time.
The amateur radio community uses at most 25kHz of bandwidth in the VHF band that spans 144MHz to 146MHz. Two different users simultaneously transmit their voices without interfering with each other by using the 144.025MHz and the 145MHz frequencies, respectively. How many users can simultaneously transmit without interfering with each other over the given VHF band?
