If 14 users are connected to a wireless network (Please check details for full question)?

Question

If 14 users are connected to a wireless network that offers a maximum data rate of 10 Mbps and a thoughput of 65%, which of the values given below is the closet to the average pactical message data rate available to each user?
1) 45 kbps
2) 90 kbps
3) 460 kbps
4) 900 kbps
5) 1.4 Mbps
6) 6.5 Mbps

Answer 1

10Mbps*.65 = 6.5 Mbps
6.5Mbps/14 = 464 kbps
Answer: 3, 460kbps

Wireless networks share bandwidth. Its sharing the bandwidth available in the air on the frequency the network uses.

Answer 2

6.5 Mbps.

Each user will have the total 65 % because wireless does not share bandwith. If one user is actually using the system for data transfer, the others will not be authorized (ACK) by the WAP to use the connection.

Answer 3

i think of you're perplexing the information value with information superhighway velocity... On an information superhighway connection, once you're 'allowed' a undeniable quantity (say, 3 gigabits), dissimilar desktops all on that one connection would have part of the relationship (no longer unavoidably precisely a million/third of the pipeline, yet I digress). in terms of a instant community, although, the router is in a position to settle for dissimilar streams *all* of which would be on the optimal (as much as fifty 4 megabits in step with 2d). this is the protocol that only helps a flow of archives to be transferred over air at that velocity. the value does *no longer* mirror the technique of the gadget to obtain at a particular velocity. In different words, each and each pc is linked to the router (wirelessly) at a velocity as much as fifty 4 megabits in step with 2d, autonomous of another. in case you have 10 desktops linked wirelessly, or 3, their individual velocity of pass does not replace. The router is in a position to maintain a number of of those connections at as quickly as. Now, 3 desktops as against 10, all making use of the internet on the comparable time (assuming they're all making use of it heavily, which includes is mandatory while documents are being transferred), will cut back the value that they obtain archives, because of the fact that there is merely one information superhighway connection and that they ought to proportion it. in case you're moving documents between desktops on the comparable community, each and each would be working at as much as fifty 4 Mbps even however they proportion one router. I say "as much as fifty 4 Mbps" because of the fact mutually as the router can shop up with that velocity, distance, environmental aspects, and a bunch of different issues can degrade the extremely velocity you obtain.

Answer 4

1.4 Mbps
