There have been 40 million HomePNA devices in operation though ( source), so it will still be possible to get them used. HomePNA was a competing standard to G.hn, but their standards group merged in 2013 with the HomeGrid forum behind their G.hn standard ( source). They also offer a concentrator as a central unit that allows to use these devices comfortably for distribution in larger compounds. Said to provide 100 Mbit/s up to 300 m, down to 20 Mbit/s at 1.7 km. Panoptic Technology IntraLAN VDSL2 P2P Modem.Provides up to 168 Mbit/s, and can cover longer ranges (4 Mbit/s at 3 km). Seems to be based on VDSL, but they don't tell. They specifically mention that a single Cat5 cable can contain up to four of these connections, allowing to multiply the speed by link aggregation. A pair of VDSL2 modems for point-to-point connections up to 100 Mbit/s (at short distance) resp. Solwise E100M, as mentioned in another answer here.See the cabling example for the Solwise E100M.Ī disadvantage of G.hn compared to VDSL / VDSL2 is that only one pair in a multi-core cable can be used for it ( source), so link aggregation requires multiple cables. This makes it more adapted to phone cabling, which usually branches into several wall sockets in the different rooms. One nice attribute of G.hn is that it's not limited to point-to-point connections like VDSL modems are. The transmission distance is up to 1000 m. That's the PHY layer signalling rate though, while the usable data rate on the IP layer would be 400 Mbit/s ( source). It provides up to 2 Gbit/s, with commercial devices for phone lines typically providing 1 Gbit/s. The Pop-Up Network Kit Mark III is a Rugged All-in-One LTE + Wi-Fi Network-in-a-Case for mobile, instant temporary internet connectivity from anywhere. So, exactly made for the purpose at hand. G.hn is a standard for home networking over legacy cabling (phone cables, coax and power lines). ![]() So for practical purposes, it does not matter that it's not Ethernet. They do not run Ethernet over the cable but protocols more adapted to the phone cable medium, but all provide Ethernet at the connector sockets used to access these connections. ![]() There are ways to use Cat3 phone cables at higher speeds, as listed below. Other answers here explore the possibility to use the Cat3 phone cabling for 10 Mbit/s (10BASE-T) Ethernet only. Options for bandwidths higher than 10 Mbit/s
