I've been wanting to build a *mobile* node. On the surface, this seems pretty easy. What makes it complicated is the internet or network connections. I'm a tmobile subscriber for cell and mobile data. I decided recently to start building my mobile data carry alongs based upon a cradlepoint router, so far so good. So my Tmobile mobile device is comprised of a cradlepoint, and their 4G usb FOB. This works great for what I need it for.. Recently I found myself in an area where I didn't have very good tmo coverage so I grabbed a Verizon 4G lte FOB. I haven't thought about *incoming* data until working on my linking projects. This is where my mobile plan fell apart. It appears that most all of these 4G/LTE providers are going to a Natted private network on the 4G/LTE side. This isn't true of their 3G network, but is of their 4G side. Well as you might imagine if you don't have control of the NAT ad port forwarding, you can't put a server on user side of a 4G device :(. BUT then I had an epiphany (probably late because everyone else is already there). The RTCM works so well for remoting my repeater.. Why not just use it as the mobile controller and instead of running a server remotely, just run an RTCM remotely back to a server. I think this will solve my problem. And perhaps make this even simpler to deal with along with a 4G type data connection. Anyone already wandered this path and what are you using? Thanks, Alan
