Your cellular phone is essentially a highly sophisticated radio, basically no different from any other
two-way radio system. The ingenuity of the cellular system lies in the splitting of the broadcasting
environment into a multitude of relatively small cells with low-power transmitters.
This “Cellular approach” to radio communication allows for extensive frequency reuse so that
millions of people can use their mobile phones simultaneously although the number of frequencies
are limited. The broadcasting cells are commonly illustrated as hexagons, typically 10 square miles
in area with the base station in the center. This arrangement allows for non-adjacent cells to use
the same frequencies without risk of interference.
Your cellular phone is in constant contact with the nearest base station. As you move from cell to
cell, e.g. while driving in your car, the base station you are approaching takes over when you are
within reach. This happens within split seconds without your noticing it.
All you experience is a stable and clear connection.
However, not all network operators provide the same coverage in all areas. Hence, if you travel
near the limit of your network’s coverage, you may experience difficulties in maintaining the
connection. The same may hap pen if the radio signal is blocked by obstacles such as high trees,
hills or buildings, or if you are inside a heavily reinforced concrete building.
