WIRELESS TECHNOLOGY
Wireless technology refers to the transmission
of data or power between two or more points
without the use of physical connections like
cables or wires. It plays a crucial role in
modern communication systems, enabling the
exchange of information over distances using
radio waves, infrared, microwaves, or other
forms of electromagnetic radiation.
,Types of wireless technology
1. Wi-Fi (Wireless Fidelity): Used for local area
networking, it allows devices like computers,
smartphones, and smart appliances to connect to the
internet or a network without cables.
2. Bluetooth: A short-range wireless technology that
enables data exchange between devices over short
distances, typically used for devices like
headphones, speakers, and keyboards.
3. Cellular Networks (e.g., 4G, 5G): These are used for
mobile communication, enabling devices like
smartphones to communicate over long distances.
Each generation brings improvements in speed,
reliability, and efficiency.
, Types of wireless technology
4. RFID (Radio Frequency Identification): A technology used
for automatically identifying and tracking tags attached to
objects, often used in logistics and supply chain management.
5. NFC (Near Field Communication): A subset of RFID, it
enables communication between devices when they are close
together, commonly used for contactless payments and access
control.
6. Satellite Communication: Used for long-distance
communication, satellites relay data between points on the
earth, often used for television broadcasts, internet services,
and global positioning systems (GPS).
7. Infrared: Used for short-range communication, typically
between devices like remote controls and televisions, or in
some short-range data transfer between devices.
, Wireless Networks – Cont’d
The following situations justify the use of wireless
technology:
• To span a distance beyond the capabilities of
typical cabling,
• To provide a backup communications link in case
of normal network failure,
• To link portable or temporary workstations,
• To overcome situations where normal cabling is
difficult or financially impractical, or
• To remotely connect mobile users or networks.
