At the same time, however, the base station in the cell you re approaching will be able to see your phone s signal strength increasing. The two base stations coordinate themselves through the MTSO, and at some point your phone gets a signal telling it to change frequencies. In short, as you move between cells, the MTSO transfers calls from one cell to another. Cell phones continue to become more technologically advanced as we move into the 21 st century. The latest innovative move with cellular technology is the new digital technology that has greatly expanded the horizons for cell phone use.
Digital transmission makes cell phones more like computers.
It transforms the voice into computer language and enables the system s capacity to greatly increase. The technology that is most commonly used in cell phones and before digital technology came about is known as analog. Analog transmission actually carries your voice through airwaves. Digital technology however stands out as being the most efficient allowing for a longer battery life and increased capacity, which means fewer calls are blocked and conversation is more private. Conventional analog transmission conversation travels on airwaves, and can therefore be mistakenly picked up by another user.
