This guide describes all the features of the 4G module for the Waspmote sensor platform. We can make HTTP navigation, downloading and uploading content to a web server. We can also set secure connections using SSL certificates and setting TCP/IP private sockets. The FTP protocol is also available which is really useful when your application requires handling files. There are different models, each one specifically designed for one market. The Plug & Sense! 4G is certified for CE, FCC, IC, ANATEL, RCM, PTCRB and AT&T.
