2. What is a Cell Tower?
• A cell tower or also known as a cell site is a
cellular telephone site where electric
communications equipment and antennae are
mounted.
• The purpose of a cell phone tower is to
facilitate the signal reception of cellular
phones and other wireless communication
devices like telephone, television, and radio in
a cellular network.

3. How does it work?
Whenever you use your mobile phone to make a call, it
emits electromagnetic radio waves also known as radio
frequency or RF energy. Once the radio waves are
emitted, the antenna from the nearest cell phone
tower will receive them. The antennas of a cell tower
can both transmit and receive signals from mobile
phones. After receiving the radio waves from a mobile
phone, it will then transmit the signals to a switching
center which is a telephone exchange for mobile
phones. This allows the call to be connected to either
another mobile phone or to a telephone network.

4. Types of Cell Towers
Cell towers could be lattice or self-support
towers, guyed towers, monopole towers, and
concealed towers. Concealed towers can be
designed to resemble trees, cacti, water towers,
signs, light standards, and other types of structures.

5. Range of Cell Towers
The working range of a cell tower depends upon
following factors:
• Height of antenna
• The frequency of signal
• The transmitter's power
• The required uplink/downlink data rate of the
subscriber's device
• The direction of the antenna
• Reflection and absorption of radio energy by buildings
or vegetation
• It may also be affected by weather conditions

6. Effects on humans?
Based on the available scientific evidence, there are
no health risks from exposure to the low levels of
radiofrequency EMF which people are exposed to
from cell phones, cell phone towers, antennas and
5G devices.
