In my experience at home and at work, it's OK unless and untill a
hub, switch, or NIC decides to get noisy. Then it's time to get out
the handheld scanner and start tracking it down. The radio shop at
WeBuildHighways, my day job, had a bad switch, and it took a day to
find out what was trashing their VHF reception.

Aside from that, it's just fine.

Ours generates noise on HF. I have a vertical antenna about 15 feet
from the house and that doesn't help. We didn't have problems with
the old-style coax cable ethernet. I'll switch to shielded cat-5
cable in the near future.

Shielded twisted pair is included within the EIA/TIA 568 standard
and is used in parts of Europe. It is more expensive to install and takes
more time to terminate (but less than the old IBM Type 1 cabling system !!)

arrrrggg type 1!!!!!!!!!!! ever see type 2... (it also had phone cable in
it!!)

Both types were a B*^ch to manage correctly!!!!!

Bob (who's fingers still hurt from type 1 terminations!!!)

Yes sir,

In the early days of networking, I had to install and support a WIDE variety
of networks and
physical media (and a few different file server OS - but largely Novell !!)

In addition to the original Token Ring 4 Mbps and Thick and Thin Ethernet
(10-Base-5 and 10-Base-2)
Altos Server and original 3com Net (Thinnet based)
Novell's S-Net
Proteon's 4-Net and 10-Net (10 Mbps 10-Net was not adopted - later IBM 16
Mbps was)
G-Net ( 1 Mbps)
Omninet (for Apple II)
ARCnet Token-passing (PC and old Datapoint 8-bit processor version)
Sytek / IBM PC Network (used 75 ohm CATV cabling)
Appletalk for Macs
AT&T StarNet (another 1 Mbps)

and others from Novell lab classes when Ray Noorda showed up and signed your
certificate!

Today, the company I work for is owned by the US patent holder for Token
Ring

.... who said the world is small?

I get interference from a hub in the basement near the rig. Most noise
is on 20 meters. The problem is especially bad if there is an
unterminated wire connected to the hub.
