Ethernet over powerline

Recently I was forced to try Ethernet over powerline because WiFi was inadequate and there was no way to pull the cable to the spot. I bought this http://www.bestbuy.com/site/tp-link-powerline-av500-nano-adapter-starter-kit-white/2080136.p?id=1219... and it worked very well for me. Your mileage may vary or no mileage at all )))... it depends, but I think it is worth trying as WiFi should be the last resort for the more demanding presentations.

We've had good luck with Ethernet over AC powerline, but it's more difficult to get a signal in commercial/industrial wiring. You've got to have transmitter and receiver modules be on the same 110VAC leg and most big buildings have 3 phase AC input and then often multiple distribution transformers.

A closer proximity (to the signage player) single purpose (signage) locked down WiFi Access point connected to cabled Ethernet is another good option sometimes at reasonable cost. A decent antenna on the access point can make a lot of difference.

WiFi in general can become the hidden stall and crash gremlin in intensive displays that may need peak bandwidth quickly at times to remain stable. The internal antennae in small players are great in a home or small office environment, but offer less bandwidth at distance when hidden behind a monitor or when a long way away from a busy access point.

I just do not like WiFi for digital signage; most of our failures happened because something went wrong with WiFi. In most of the cases clients hardware is to blame. Also WiFi really limits your options for where you can put your device. We have a couple of these sitting in the metal boxes and for that we needed to add additional external adapter/antenna, which proved to be nothing else, but another chain in the system that can fail.

RPTDigital,

Can you elaborate more on this. What hardware do you have in mind?

Darius,

Any decent Ethernet to WiFi Access Point will work, we've used D-Link and others. If POE is available (Look for VOIP phones) then you save the power block and can mount the access point anywhere nearby you can have a cable to nearest POE Ethernet port.  If no POE, use any decent WiFi Access point.

We have POE on our phones and they have a POE splitter built in so we used this in our shop connected to a phone without a computer close by:

Set the SSID name and password to ensure privacy and to ensure that only the signage will use set it up to not be visible so that everyone who's looking for free WiFi doesn't see it or try to log on. That'll give you a clear underused WiFi connection to the wired network over up to several hundred feet.
