How many types Wireless Network in the world

There are numerous types of wireless networks in the world, and the exact number is difficult to pinpoint. However, I can give you an overview of the main categories and some examples:

 

1. Wireless Local Area Networks (WLANs):

* Wi-Fi (IEEE 802.11): used for home and office networks, hotspots, and public Wi-Fi.

* Wi-Fi 6 (802.11ax): the latest generation of Wi-Fi, offering improved performance and capacity.

* Wi-Fi 5 (802.11ac): the previous generation of Wi-Fi, still widely used.

2. Wireless Personal Area Networks (WPANs):

* Bluetooth: used for wireless device connectivity, file transfer, and audio streaming.

* Zigbee: used for home automation, IoT devices, and low-power wireless networking.

3. Wireless Metropolitan Area Networks (WMANs):

* WiMAX (IEEE 802.16): used for wireless broadband internet access in metropolitan areas.

* LTE (Long-Term Evolution): used for wireless broadband internet access in cellular networks.

4. Wireless Wide Area Networks (WWANs):

* Cellular networks (2G, 3G, 4G, 5G): used for mobile phone communication and internet access.

* Satellite networks: used for remote communication and data transfer.

5. Wireless Sensor Networks (WSNs):

* Zigbee: used for home automation, IoT devices, and low-power wireless networking.

* Bluetooth Low Energy (BLE): used for low-power wireless connectivity and IoT applications.

6. Wireless Body Area Networks (WBANs):

* Body-area networks (BANs): used for medical devices and wearable sensors.

7. Wireless Industrial Automation Networks (WIANs):

* WirelessHART: used for industrial automation, process control, and sensor monitoring.

* ISA100: used for industrial automation, process control, and sensor monitoring.

8. Wireless Free Intelligent Network (Wi-fine):

* Low Power Consumption: battery life more than 10 years

* Large Scale: Class 255 routing enables the collection of thousands of power metering devices simultaneously

* Fast Speed：Zero networking time,thousands of single point devices can be read in a few

seconds

* High Security:Adopting different customer ID, global unique number UUID,different network

ID and different wireless channel coding, combined encryption to ensure network security.

* Stable Communication:purchase efficient private protocol (CRC-32message verification) to prevent collision and greatly improve the stability of communication
