Advantages of wireless network | disadvantages of wireless network

This page covers advantages and disadvantages of wireless network. It mentions benefits or advantages of wireless network and drawbacks or disadvantages of wireless network.

What is wireless network?

Introduction:
Wireless network consists of wireless connection between various parts (transmitter, receiver) of the wireless system. This system does not require any wires such as cables, optical cables, twisted pair etc. The EM (Electromagnetic) waves are used between transmitter and receiver to carry information using various modulation techniques. Antennas are used to transmit/receive EM waves to/from the air.

wireless networks-Satellite,Cellular,WLAN,Microwave link

Examples of wireless network:
• Satellite communication network
• Cellular communication systems for outdoor communication such as GSM, CDMA, HSPA, Wimax, LTE (i.e. 4G), 5G, 6G etc.
• Indoor wireless communication systems such as WLAN, Zigbee, Bluetooth, Zwave etc.
• Microwave link for point to point long distance communication
• IoT wireless networks such as LoRa, Sigfox, LTE-M, NB-IoT etc. used as LPWA (Low Power Wireless Access) networks.

Benefits or advantages of wireless network

Following are the benefits or advantages of wireless network:
➨Wireless networks are easy to install and maintain.
➨They offer flexibility and mobility during usage.
➨The wireless signals are available behind the walls and on hilly terrains and hence it can provide service independant of location.
➨Prices are very low due to large number of mobile user devices from number of manufacturers.
➨Wireless networks cover wide coverage areas with the help of appropriate signal strength and modulation techniques.
➨File sharing is easier task using wireless connections such as wifi, bluetooth and so on.

Drawbacks or disadvantages of wireless network

Following are the drawbacks or disadvantages of wireless network:
➨Wireless network offers lower speed compare to wired network.
➨Wireless network offers less bandwidth compare to wired network as wireless networks use frequency spectrum which is very scarse resource.
➨Wireless networks are less secure compare to wired networks.
➨Wireless networks are prone to interference from nearby wireless networks and from other fading conditions.
➨Quality of service is poor due to jitter and delay in connection setup time.

Conclusion: In order to understand advantages of wireless network and disadvantages of wireless network one has to understand difference between wired network versus wireless network >>.
