3. Introduction
Wireless technology has revolutionized the way we
communicate, connect, and interact with the world around us.
It's a fascinating field that enables the transmission of
information without physical connections, allowing devices to
communicate and share data seamlessly.
At its core, wireless technology uses electromagnetic waves to
transmit signals through the air, eliminating the need for wires
or cables. This technology encompasses a vast array of
applications, from wireless internet (Wi-Fi) and Bluetooth for
short-range communication to cellular networks that enable
mobile communication across long distances.

4. What is wireless technology?
Wireless technology refers to the transmission of data or information
without the use of physical connections, such as wires or cables. It
utilizes electromagnetic waves to send signals between devices,
enabling communication and data transfer over short or long
distances.

5. This technology encompasses
various forms of
communication, including:
• Satellite Communication: Satellite communication is a
wireless technology that uses artificial satellites positioned in
space to facilitate communication across vast distances on
Earth. It's a pivotal aspect of global telecommunications,
enabling various applications ranging from broadcasting to
military operations and everyday connectivity.

6. • Cellular Networks: These networks (such as
3G, 4G LTE, and 5G) enable long-range
communication, providing mobile devices with
voice calling, text messaging, and internet
connectivity. They rely on cell towers to transmit
signals across wider geographical areas.

• RFID (Radio-Frequency Identification):
Utilizes electromagnetic fields to
automatically identify and track tags
attached to objects. It's used in various
industries for tracking inventory, contactless
payment systems, and access control.

7. • Bluetooth: Used for short-range
communication between devices
(usually within 10 meters), it's
commonly employed in audio
streaming, file transfer, and
connecting peripherals like
keyboards, mice, and speakers to
computers or smartphones
Presentation title 7
• Wi-Fi (IEEE 802.11): Enables
devices to connect to a local area
network (LAN) wirelessly, allowing
access to the internet within a
certain range. Different standards
like 802.11a, 802.11b, 802.11g,
802.11n, 802.11ac, and 802.11ax
offer varying speeds and
frequencies.
