Classification of different wireless communication networks
Wireless communication networks can be classified into various categories based on different
criteria such as range, data rate, coverage area, topology, and purpose. Here's a classification
based on some of these criteria:
1. Range:
 Personal Area Network (PAN): Covers a very small area, typically within a range
of a few meters to about 10 meters. Examples include Bluetooth and Zigbee.
 Local Area Network (LAN): Covers a small area such as a home, office, or
campus. Typically operates within a range of tens to a few hundred meters.
Examples include Wi-Fi (IEEE 802.11).
 Metropolitan Area Network (MAN): Covers a larger geographical area such as a
city or town. Operates within a range of several kilometers. Examples include
WiMAX (IEEE 802.16).
 Wide Area Network (WAN): Covers a large geographical area, typically spanning
cities, countries, or continents. Examples include cellular networks like GSM, LTE,
and 5G.
2. Data Rate:
 Low Data Rate Networks: Designed for low-power, low-bandwidth applications.
Examples include RFID, NFC, and some IoT protocols.
 Medium Data Rate Networks: Offer moderate bandwidth suitable for
applications like home internet, streaming, and file sharing. Examples include WiFi and Bluetooth.
 High Data Rate Networks: Provide high-speed data transfer suitable for
multimedia streaming, gaming, and high-definition video. Examples include LTE,
5G, and WiMAX.
3. Topology:
 Mesh Network: Nodes are interconnected, providing multiple paths for data to
travel. Examples include Zigbee and some ad hoc networks.
 Star Network: All nodes are connected to a central hub. Examples include Wi-Fi
networks.
 Bus Network: All nodes share a single communication line. Ethernet networks are
a common example.
 Ring Network: Each node is connected to exactly two other nodes, forming a
ring-like structure. Token Ring is an example.
4. Purpose:
 Consumer Communication Networks: Designed for personal or household use,
such as Wi-Fi, Bluetooth, and Zigbee.
 Industrial and IoT Networks: Optimized for machine-to-machine
communication and industrial automation, including protocols like MQTT, Zigbee,
and LoRaWAN.
 Telecommunication Networks: Provide voice and data communication services
to a wide range of users, including cellular networks like GSM, LTE, and 5G.
 Satellite Networks: Utilize satellites to enable communication over large
distances, suitable for remote areas and global coverage.
5. Coverage Area:
 Indoor Networks: Designed to provide coverage within buildings or enclosed
spaces. Examples include Wi-Fi and Bluetooth.
 Outdoor Networks: Designed to provide coverage in open spaces or across wide
geographical areas. Examples include cellular networks like LTE and 5G.
