I’m not 100% sure if the data is out there, but I’m trying to find data for the wifi range on the WiFi only Note Card. I’m developing a WiFi device that gives the customer the option for one connection type to the network for a specific use case. I have a Note Carrier A , X, CX here for testing. Can anyone provide actual results from their testing so I at least have a baseline to compare to. If the range is not that great, I might have to go a different direction. Also worth noting, why didn’t Blues develop the board with an external antenna option? I have two days to figure this out before I’m stuck with buying 200 at a time. If anyone has any info, please share.
Thank you,
JH
Hi @Howellj1 and welcome to the Blues community!
Unfortunately you’re not going to find a documented range for the Silicon Labs WFM200S WiFi module that’s used on the Notecard WiFi. There are just too many external variables involved (e.g. environmental factors, enclosures, obstructions, etc). After doing some searches I did find some anecdotal reports though of ~10–50 meters indoor and ~100–300+ meters outdoor (line of sight).
Hope that helps!

I found the same info that Ai generated, couldn’t depend on it’s accuracy so I came here. Totally get the variables! Was there a particular reason why the wifi only card didn’t include the connector for the external antenna? I can’t think of a logical reason as to why it was not added. I was hoping to order at least 1,000 of the wifi cards for production, not sure what to do now. Thank you for the quick reply.
I did some wifi range tests with the WiFi only Notecard connecting to our router inside our office which is a metal building and only got reliable data transfer at 140 foot range (40 ft inside building and 100 ft outside building.
The notecard was identifying other height boring routers at distances up to 1/4 mile, but I don’t know if I could connect to them.
FWIW,

Thank you for the feedback! I’m waiting for a couple enclosures before I can test my stack. I’m in Montana where there’s hardly any interference. Hoping to get a usable signal so I can start production and get my units sold. I will report back once I have my testing done in a zero interference setting.
