What are various networking data transfer speeds (how fast is ethernet, phone line transmission, token ring, ...)

[rnmcd]

I have a 10/100 PCMCIA card and about all I know about it is that it will transfer network data at either 10mb/sec or 100mb/sec. Is that slow compared to some types of broadband?

The router that I have is 22mb/sec. Would I notice much improvement if my PCMCIA card was 22mb/sec too?

Are 22mb/sec NIC cards available?

Thanks.

Optimum Online was a cable provider that offered near 10 Mbps pipes. Not sure if they're around anymore but the vast majority of broadband providers are 1-2+ Mb. Don't worry about using up your available bandwidth on a 10BaseT network card, much less a 100 Mb card.

The 22 Mb, 802.11b+ devices will bench out at around 7-8 Mb real world throughput where the standard 802.11b radios are in the 4-5 Mb range, so not quite double the bandwidth. If your running 802.11b client cards with your 802.11b+ AP then your losing some available bandwidth. Replacing your client cards with .11b+ cards will improve your local file transfer speeds but do nothing for your internet speeds. assuming you don't have a T3 at your house.

22mbps is how fast the wireless part of it is, the wired part is 100megabits/full duplex most likely. They do make 22mbps wireless cards, just make sure it is compatible with your access point. Your broadband is nowhere near 22megabits though, so it won't speed up your internet access.

802.3 (ethernet) - 10 Mbps
802.3u (fast ethernet) - 100 Mbps
802.3z (gigabit ethernet) - 1000 Mbps OR 1Gbps
802.5 (token ring) - 16Mbps (there were also 4 and 100 Mbps versions)
802.11b (WiFi or Wireless Ethernet) - 11 Mbps (some proprietary extensions can increase it to 22 Mbps)
802.11a (no nickname i've heard) - 54 Mbps

It sounds like your "22mb/sec router" is actually a router with an intergrated 802.11b wireless access point (WAP) that has some proprietary extensions that allow it to transmit at 22 Mbps (D-Link perhaps?)

Your router probably also has an intergrated switch. My bet is its an auto-sensing 10/100 ethernet switch. So in this case your 10/100 card should automatically be detected as capable of 100 Mbps and used at that speed.

hopefully this answered more questions than it created

Wow, thanks for all of the great information.

Does anyone happen to know how fast transmission over a phone line network is?

802.11b at 22Mb/sec. referred by some as Turbo 802.11b

==========================================

PhoneLine.

HomePNA -1 Mbps.

HomePNA 2.0 - 10 Mbps

HomePNA 3.0 - 100 Mbps. Yet to come.

==========================================

Home Plug (aka Powerline) - 14Mbps.
