Wireless Networking
Wireless networking is a way of connecting devices such as computers,
smartphones and tablets without using physical cables. With the use of radio
waves or signals, data is transmitted between devices, allowing them to
communicate over a network.

How does it work?


It starts with an internet connection from an Internet Service Provider (ISP),
which is connected to a router. The router acts as the central hub and creates a
wireless signal using radio waves. When devices like smartphones, laptops, or
tablets want to connect, they search for available Wi-Fi networks. After selecting
a network and entering the password, the device sends a connection request to
the router, which assigns it an IP address. Data is then transmitted back and
forth between the device and the router using radio signals, allowing users to
browse the internet and communicate wirelessly. Security measures like
passwords keep the network safe from unauthorized access.

Types of Wireless Networks


wireless networks come in various types, each designed for different uses and
distances.
 Wi-Fi (Wireless Fidelity): Wi-Fi is one of the most common wireless
technologies. It enables devices like laptops, smartphones, and tablets to
connect to the internet within a certain range. Wi-Fi is used at home, in
offices, and in public spaces like cafes and airports. It provides high-speed
internet access, and modern Wi-Fi standards, such as Wi-Fi 6, offer even
faster speeds and better performance.
 Bluetooth: Bluetooth is a wireless technology designed for short-range
communication. It’s commonly used to connect devices like headphones,
keyboards, and speakers to computers and phones. Bluetooth is ideal for
low-power applications and does not require an internet connection.
 Cellular Networks (4G, 5G): Cellular networks allow devices to connect
to the internet and make calls over long distances. These networks are
provided by telecom companies and cover large geographical areas. 4G
and 5G are popular cellular network standards, with 5G offering faster
speeds and lower latency than its predecessors.
 Satellite: Satellite networks use orbiting satellites to provide internet
access to remote areas where traditional wired networks are unavailable.
Satellite internet is useful for regions with limited connectivity options, but
it can have higher latency due to the long distance data must travel.
