# Difference between 801.11b and 801.11g

sorry if i am coming in late... but "a" is faster then "b"?

Geffy said:
wireless 11g is 54Mbps and operates in the 2.4 GHz band, 11a is 108MBps and operates in the 5 GHz band

wireless 11b is 11MBps and in the 2.4GHz band as well

Where did you get that info from?

Here it is plain and simple:

802.11A
Theoretical Throughput: 54Mb
Average Throughput: 30Mb
Frequency: 5GHz via Orthogonal Frequency Division Multiplexing (OFDM)
Theoretical Range: 300ft (100m) radius
Average Range: 200ft (67m) radius

802.11B Wi-fi
Theoretical Throughput: 11Mb with 5.5Mb and 1Mb Fallback
Average Throughput: 8-10Mb
Frequency: 2.4GHz via Direct-Sequence Spread Spectrum (DSSS)
Theoretical Range: 1000ft (333m) radius
Average Range: 500-700ft (167 - 233m) radius
Compression Ratio: 2:1 (22Mb via TI Compression Algorithm)

802.11G Wi-fi+
Theoretical Throughput: 54Mb with 11Mb, 5.5Mb, and 1Mb Fallback
Average Throughput: 20Mb
Frequency: 2.4GHz via Direct-Sequence Spread Spectrum (DSSS)
Theoretical Range: 1000ft (333m) radius
Average Range: 800ft (267m) radius
Compression Ratio: 2:1 (108Mb via TI Compression Algorithm)
Backward Compatible with 802.11B via fallback.

802.11A/B
Device that can accept both A and B connections

^^ that is very clear and right. not quite sure what feggy was saying??

thats exactly what I was saying, cept I thought that the A did up to 108, but I guess it accomplishes that with two connections or however it was described above, and I thought G could only do up to 54.
other than that tis the same. I have a Atheros A/B/G card so I can connect to any of those. (well I could if it wasnt being a b!tch of a thing to get working on my laptop in BSD)

btw these are the different connection rates for 11b and 11g respectively
ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ath0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps

Also Hi EP and people. I found this place again while looking through a oooollllllldddd backup. I have filled over 10TB and was looking at my collection of antiques. Any bids on the 500Mhz Win 95 fix?
Any of the SP crew still out there?
Impressed you have kept this alive this long EP! So many sites have come and gone.

Just did some crude math and I apparently joined almost 18yrs ago, how is that possible???
hello peeps... is been some time since i last came here.
Rest in peace my friend, been trying to find you and finally did in the worst way imaginable.
