Hello,
Can someone clear up my confusion on Cable vs Wireless speeds. If cable has 3,4, or 5 Mbps speeds and Wi-Fi 802.11 speeds are 54 Mbps is the wireless faster than the cable?. Please someone help me with this?

Thank's..

With cable, the quoted speeds are in Mbps (down or up).

With WiFi, the 54Mbps is the aggregate (i.e. sum) of the bandwidth available in both directions so you only really get about 10 or 15Mbps in each direction once overhead is taken out.

In practice, I find that I get about 12Mbps transferring files from my desktop to my laptop over 54Mbps WiFi (which is fine for what I need)

Jimmyv: So Wi-Fi is faster than Cable ?

Well... There's cable and then there's CABLE...

I have heard of some connections using Optical Fibre which can deliver 100Mbps to your door, but only if you live in the CBD of a major city. In NZ there are options such as Citylink for those lucky people.

I would say that IN GENERAL WiFi is faster than cable internet, especially the new versions of "Draft N" WiFi, but there are always exceptions.
