When it comes to connectivity on the road their is no better resource than the experts at :

These Technomads have done the leg work and go to great lengths to keep everyone up to date on the most current pricing, changes, and products in the industry.

The Book is a great place to baseline your understanding of the industry. I feel I am informed about much of this industry having started selling computers in 1979. I bought my first 3 watt cellular car phone in 1986 and have embraced the industry and the changes for over 30 years. With that said, I thought I knew the industry pretty well though these guys took my understanding to a whole new level with Mobile technology for the RVer. I read the entire book last year and can say without question it is of High -Value for us RVers. Thanks Chris & Cherie!
