Title: How Much Of A Bottleneck Is Wifi?
Post by: bluedevils on December 17, 2004, 09:08:06 pm

I know wifi has a very limited bandwidth, but my cablemodem also is limited on uploads.  How much of a bottleneck would the wifi be for a webserver?  It would be serving pics up to 1MB in size to just family and friends.

Look at your end-to-end network path and see what part has the slowest connection.  802.11b will go up to 11Mega Bits/sec if you're close to the router and will drop off as you get interference.  Even it it drops to 1MB/s it should be faster than the upload speed cap which is (in my area) rated in Kilo Bits/sec.

hmmm....I guess I'll just have to do experiments with it.  Thanks Tehas.

Just to add to what has been said:

With 802.11b you typically get "real" transfer rates of around 1/2 whatever speed you are connecting at.

well my sister in vancouver viewed the 1mb pictures and the transfer time seemed acceptable (under 10sec) and 640 x 480 at about 1sec.  Maybe tonight she can test the diff with the Z hooked up to the ethernet (socket LPE).  The ethernet card will be my main webserving connection, but I will take it out of the docking port and host the site using wifi when I want to walk around with it.
