How much latency does wifi through ceiling put on connection?

[Appledrop]

Hi quick question: if my router is downstairs and the wireless access point is there, trhen how much latency will i see, in games for example, how much ping will be added, just communicating with the access point? Also which pci card and acess point will assure me a good connection through the ceiling?

thankyou!

I'm on my laptop upstairs pinging my wireless router, which is downstairs and across the house, and getting <2 ms round trip on average (mostly 1.6-1.75 ms with one spike of about 3 ms).
I don't know about pci cards, but my Linksys router hase given me a better signal than either an Actiontek or an SMC router.

oh wow, i thought the hit would be more like 10ms (20ms round trip) =l Interesting, thanks.. I'll look into linksys too .

Should be no latency since they are radio waves which pass through concrete.

Bandwidth (or ?Speed?) depends on what standard you use (802.11b. 802.11g, etc.) and how much of the signal is available for processing. The smaller the signal the less bandwidth you get.

Latency per se is Not created by obstructions; the Radio signal travels in the speed of light no matter what. Latency is a matter of timing that depends more on the Hardware, and the processing that is performed on the signal by both the hardware and software.

You might have Strong signal (like Wireless Satellite Internet), and Hi latency due to the way the Satellite signal is processes.

In home environment Bandwidth and Latency might be related when you have unstable signal. Unstable signal has to be processed more and results in reduction of Bandwidth and slight addition to latency.

If you make it your business to have a Clean Stable signal Latency would not be a problem.

Clean Signal is not necessarily Strong signal but rather the best Signal to Noise Ration (SNR) that can be achieved.

Unfortunately the Green Bars of the signal strength provided by most Wireless Utilities it is more of a Gimmick rather then a Technical tool. It shows the actual 802.11x signal + Phone + Microwaves + Brain emissions (j/k), in other words they give a visual representation of all the 2.4GHz in the atmosphere around them.

The real measure of Wireless signal capacity is Signal to Noise Ratio (SNR), a measure that takes into consideration the relevant Signal adjusted to the Noise Level.

Unfortunately it is hard for us to identify and eliminate noise, thus the way to neutralize the noise and improve SNR is to get strong signal while the source and the client are physically as close as possible.

Doing so might cost more money, but there is not really another way.

The following links describe variety of ways to achieve better signal.
