Trimble VRS networks provide many benefits to users who work in areas where the networks are available. However, a lot of users do not understand how the network works. Also, when additional devices used to connect to the internet for corrections get involved, additional problems typically follow. In this Trimble VRS discussion we give attendees and overview of the system and how it works. We also discuss ways to best utilize the networks to get accurate data. We also go through many of the known support-related issues when dealing with mobile internet connections, and the proper setup in Trimble Software. In this session we provide our suggestions for third-party devices based on our support experiences. This session will be a must see for anyone who surveys on a Trimble VRS network.
