The cell phone replaces the radio or wires that connect from you receiver to the base. The network bases in stead of connecting to receiver by wires or radio all connect to the internet. Just like when computers are networked. You can access information on one computer without actually being on that computer because they are network. So when you turn on the phone it connects to those base stations. Then the phone uses Blue tooth to send/receive data to the receiving rover. This is why the phone has to be close to the receiving rover because if the blue tooth phone gets out of range from that rover then the connection is lost. So the cell phone only acts as a radio for sending data that is gathered. And because all these bases are networked and you use all that are on that network for each shot your data is more accurate. It would be like setting up 100 or more bases on your job and having them all communicate to your receiving rover. Hope this information helps you understand it better.

The reference station acts like a base station setup, except that it communicates using the cellular network either via the internet or similar to the way fax machines work. The website it goes to is the address of the reference station. The info transmitted from the reference station to the rover is essentially the same information that would be transmitted from a regular base setup to the rover. How the cell phone connects to the reference station, the number it dials, how the network works are all going to vary based on what the network supports.

IW3905 – the brand’s Replica Rolex first in-house manufactured flyback Tag Heuer Replica chronograph with a world time complication. This new Spitfire design cleans up the dial a great deal by omitting the chronograph and red-tipped 24-hour hand in the center of the dial but adds in an altimeter-style Replica Designer Handbags 24-hour aperture that we haven’t seen on an IWC Pilot since the UTC TCZ an excellent, but lesser-known reference from 1998
