- wmf 5y agoPoE isn't used much in home networking.
- mccanntech 5y agoEspecially in mesh kits which are usually operated without Ethernet backhaul. eero themselves claim 90% of their deployed networks don't use any Ethernet. Hence, almost all mesh kits use USB-C or a DC barrel connector.
- rektide 5y agoNot cheap but there are PoE to ethernet+usb-pd splitters. You could set up your PoE & put one of these at the end[1]. The dual band all ask for "15W usb-c" and the tri band all ask for 27W usb-c, which is probably 5V3A and 9V3A respectively. I'd expect that you could _probably_ get by with a much much cheaper non-PD splitter that simply provides the expected voltage. This feels like a pretty good compromise. USB-C PD is, per watt, often half the price or less, and it's convenience imo cannot be beat since it's such a common power delivery system. Small GaN based adapters with multiple ports are abundant and cheap (<$0.50/watt) versus more specialized, less common gear that's more expensive (often >$1.00/watt). It does feel great having one and only one cable! Right now PoE is the winner here, especially because it has range. I'd love to see USB try & compete a little more. I'd create a USB long range standard- target 5Gbps (or 2.5Gbps?) but for many meter long runs, with power-delivery. Now that we have (on paper) extended-power USB-C with 48V power, restricting ourselves down to 1A would still be quite useful (48W)!
