Not all NME-WiFi Gateways are created equal (SiTex MDA-5 AIS)

Not all NMEA->Wifi gateways are created the same.

I wanted a Class B+ AIS transceiver, and ended up buying a SiTex MDA-5, since it had a built in antenna splitter, which would make installation easy, and was a (relatively) good price. As a bonus, it had a WiFi gateway.

I vacillated on the WiFi gateway, since I could see ending up with an obsolete gateway, while the AIS transceiver would be used for years. But I reasoned that I could always disable the WiFi gateway later on.

So what I have found:
1. No capability to disable the WiFi gateway. So if I don't use it, I am wasting battery life running a Wifi network
2. The WiFi gateway only sends three words: AIVDM and AIVDO (AIS information) and GNRMC (Global Minimum Navigation covering GPS position, SOG, Track made good).

So... none of the goodness you would get over a proper NMEA2000-WiFi gateway. No wind speed/direction, AP information, etc.

Guess I should have stuck with my initial choices. Originally looking at Em-Track EM350 or AMECB600. And maybe adding a MEA2000 gateway later like the Yacht Devices YDWG-02 gateway.

I searched online, and I could find no real reviews or forum opinions on any of the AIS transceivers that included WiFi gateways.

Re: Not all NME-WiFi Gateways are created equal (SiTex MDA-5 AIS)

To be fair to them, they clearly state in the brochure and website that the wifi translates only AIS and position data. As for power usage, the entire operation, including 5W transmissions and wifi, only uses 220mA - 5Ah/day. Turning off the wifi might save 1Ah/day? Power usage doesn't seem to be an issue.

We have a Vesper XB-8000 with a built-in wifi gateway. It will output wirelessly all NMEA0183 sentences it receives, but only select NMEA2000 translations. However, it does translate more N2K than the SciTex, including all common ones such as depth, speed, distance, temperature, pressure, true and apparent wind data, compass data, navigation data, XTE, route/waypoint data, and probably some others I'm forgetting. It does not translate/transmit rudder position, engine data, and many other N2K PGN's not as critical to navigation.

Vesper was continually updating the translation abilities, but seems to have stopped adding new ones a while ago.

If you need absolutely all of your N2K data over wifi, then a dedicated gateway is probably best.
