Step by step
Solved in 2 steps
- With a local area network based on Ethernet, what is the maximum data rate that can be achieved?Figure out how many host bits the following network addresses have: --145.102.0.0/20 --212.55.180.0/30What is the length of a bit in a channel with a propagation speed of 2 x 108 m/s if the channel bandwidth is 1 Mbps? 10 Mbps? 100 Mbps?
- A group of network users share a 6Mbps network link. Each user requires 125kbps when transmitting, but only transmits for 10% of the time. If the network is circuit-switched, how many users can be supported?If the bandwidth of the network is 10Mbps, which is used to transmit the data between two nodes which are 200 meters apart with the velocity of 2 X 108 m/s. Calculate the minimum size of frame (in Bits) to acquire the channelIn GSM, there are 8 separate time slots that makeup what is known as a “TDMA frame’’. Each GSM time slot lasts for 577 µs (microseconds) and contains more than simply a sample of each individual signal.What is the total number of bits, including data and control, in a TDMA frame?
- If a wireless channel for video transmission needs 6 MHz, how many channels can there be in the millimetre-wave 5G technologies?You are designing the Wi-Fi for a classroom of 20 students and all students are using Wi-Fi at the same time. The protocol efficiency is 40% and the channel utilization is 80%. Each students uses a throughput of 2 Mbps. What is the minimum PHY rate requirement for the radio in Mbps?Suppose that we are sending a 30 Mb MP3 file from a source host to a destination host. All links in the path between source and destination have a transmission rate of 10 Mbps. Assume that the propagation speed is 2 × 108 meters/sec, and the distance between source and destination is 10,000 km. 1. Now suppose there is only one link between source and destination, and there are 10 FDM channels in the link. The MP3 file is sent over one of the channels. What is the end-to-end delay?
- When compared to conventional networks, throughput loss in wireless networks is much greater. I am curious as to the specific reasoning for this.what is a modem connection speed in kbps, if the circuit symbol rate is 13 thousand of symbols per second and the modulation is using 3 bits per symbol?The Advanced Mobile Phone System (AMPS) uses two bands. The first band of 824 to 849 MHz is used for sending, and 869 to 894 MHz is used for receiving. Each user has a bandwidth of 30 kHz in each direction. How many people can use their cellular phones simultaneously?
