Re: [opentracker] OpenTracker USB released
- It sounds like a very exciting platform! Lots of things are going to be
possible in this.
If 3G and 4G continue to come down in cost, it might even become a
node-in-a-box. There are already a lot of cheap hotspots with WiFi on the
market. At a remote site, a phone line with DSL versus a low cost 3G account...
they're getting closer in price.
