802.11g
So I'm feverishly reading up on A+, Network+ and Linux+... In my massive 1000 page A+ book, we just touched based on networking. (Which I've already been reading in depth with my Network+ book.) The concepts are similarly presented and explained (except Mike Meyers is an awesomely cool writer and is much more fun to toil through)... Except for one thing.
Each chapter has a Q and A with answers that you're supposed to submit to your teacher online. Kind of defeats the purpose with the page numbers right freakin' there, but oh well. Here's a question for you:
Under ideal conditions, the 802.11g standard supports data throughput of up to ____ and has a range of up to ____.
A. 11Mbps/150 feet
B. 11Mbps/300 feet
C. 54Mbps/150 feet
D. 54Mbps/300 feet
Simple, right? (Bet you can tell there's a catch coming up.) Wrong. There's a chart in the book that clearly lists 802.11g at having a maximum theoretical throughput of 54Mbps with an optimal range of 300 feet. The book beats into you the fact that wireless throughput is entire theoretical and is subject to overhead and is thusly much lower than advertised, but he didn't say what the practical throughput was. Under perfectly ideal conditions, it should be 54Mbps and 300 feet, right? So that's what I picked.
Answer is as follows:
B. Under ideal conditions, the 802.11g standard supports data throughput of up to 11Mbps and has a rage of up to 300 feet.
Am I missing something? I could understand a typo if the question said 802.11g and the answers said 802.11b, but it doesn't... It's clearly tacking 802.11b's standards onto 802.11g. G is supposed to be faster, B is supposed to be slower. Router boxes say it, WAP boxes say it, the book says it, the other book says it.
Yeah, that bugs me, because putting down what's clearly the right answer is going to be marked as wrong, but if I put down the wrong answer and the teacher manually reads the work and goes "huh? this guy's wrong" without checking the book, it'll still be wrong.
So I ask you... Am I missing something?
