You are talking about two cometelt different technologies. You are talking about 10BASE2 Ethernet which runs over RG-58/U coax cabling and as you mention requires termination at each end. It ran at a speed of 10Mbs. It could be unreliable for a variety of reasons such as connections coming lose, someone deciding to move their computer disconnecting a cable and breaking the continuos connection between stations that is required or a large number of Ethernet collisions because if either misbehaving nics or too many stations on a segment.

Currently there is MOCA hardware which supports speeds up to 2.5Gbs. The standard for 10Gbs has been released but no hardware for it is currently available. At least not to consumers. MOCA runs over the coax that is often already installed in homes to support cable, satellite or over the air antenna TV. It uses different frequencies and thus can coexist with these on the same cable. MOCA is not Ethernet. It is a half duplex shared medium protocol using time division multiplexing. It was originally developed to distribute IP TV without the need to run additional wiring in a house. Today it is mostly used to bring broadband internet connections into a home or to bridge Ethernet connections through a home. Different frequencies are set aside for each purpose and so both can be done at the same time. It is very reliable. I use it to extend my network to several out buildings on my property which had coax run to them many many years ago.

Thanks for that - very informative. I must admit I haven't done anything with wired networks for many years! But I still like twisted pair, and wifi :-)
