|Corinex CableLAN Adapter|
|Summary||Ethernet-over-coax adapter based on HomePlug technology. Uses TV coax instead of power wiring.|
|Pros||• The only Ethernet-over-coax solution currently available
• More robust than phone and power line networking methods
• Up to 700 meter range
|Cons||• 5Mbps throughput best case
• Requires filter if connected to same coax as DOCSIS cable modem
Alternative networking products that make use of phone and power wiring have been around for a few years, but have met with limited success. HPNA (phone line) networking seems to have pretty much fallen by the wayside, but HomePlug (power line) based networking still seems to be hanging in.
Both techniques can provide best-case speeds slightly lower than provided by 10Mbps Ethernet, but the electrical challenges provided by typical phone and power wiring often limit their performance to much slower speeds, or prevent operation entirely.
Until recently, coax TV cabling - the other wire running to multiple rooms in many homes - hasn't been a networking option. Though its superior electrical characteristics would seem to make it a natural to be pressed into service for networking use, it just didn't happen - until now.
By the way, this article was originally going to be a comparison of Ethernet-over-coax products from Corinex, Entropic and Coaxsys, but Corinex turned out to be the only company willing (or able!) to submit product for review.
