Re: Does the wireless lower the band width?

The width of a band is usually 6-10, but depends on the width of the street;
tubas and french horns lower the band's width. ;-)

I don't know what your real question is, so I'll answer a couple:

1. WiFi links do dynamically change data rate based on signal quality
and interference.

2. WiFi links are typically slower than wired links: for today's typical
SOHO links, 54 Mb/s < 100 Mb/s.

3. WiFi links are typically less efficient than wired links, due in part to
protocol differences. Sustained disk-disk transfers over a decent SOHO
100 Mb/s wired path show >75% of that 100 Mb/s; my expectation for a
comparable infrastructure WiFi path are more like 25-50% of that 54 Mb/s,
and can be far less with interference.

4. With two good PCs connected to a DSL/cable modem, one via a wired 100 Mb/s
link to a router and one via a 54 Mb/s WiFi link to the same router, both
PCs should get about the same sustained download speed from the web,
because most DSL and cable connections are much slower than either wired
or WiFi links.
