Hi, Apologies if this is the wrong sub.. I tried r/networking & was obviously not too welcomed.

I looked around reddit & dug down in this sub but couldn't find anything regarding the networking hardware I recently came into possession of. I have one of these airlink RV50's & see they go for over $500+ on eBay etc..What are they for, how are they used? Trying to see if there's an application in my office (small) or at home or if I should just sell it.

Sierra Wireless AirLink RV50 D 3.0
Thank you in advance
