Why can't WiFi work as full duplex while 3G and 4G can
The World of Wireless Communication
Wireless communication has revolutionized our world, enabling us to stay connected and access information from anywhere, at any time. Whether it's through WiFi, 3G, or 4G, we rely on these technologies to keep us connected on a daily basis. However, have you ever wondered why WiFi cannot achieve full duplex transmission, while 3G and 4G can?
The Difference Between Half Duplex and Full Duplex
To understand why WiFi operates in half duplex mode, while 3G and 4G can achieve full duplex, we must first explore the difference between the two.
Half Duplex
In half duplex communication, data can only be transmitted in one direction at a time. This means that devices must take turns sending and receiving data, resulting in a slower and less efficient transfer of information. In the case of WiFi, this limitation arises due to the nature of how wireless networks are designed.
Full Duplex
In contrast, full duplex communication allows simultaneous data transmission and reception in both directions. This enables faster and more efficient communication, as devices can send and receive data simultaneously. The ability of 3G and 4G networks to achieve full duplex is a result of technological advancements and the use of different frequency bands.
The Technical Limitations of WiFi
WiFi, also known as IEEE 802.11, operates in the unlicensed frequency bands, such as 2.4 GHz and 5 GHz. These frequency bands are shared by various devices, including routers, smartphones, laptops, and smart home devices. This shared spectrum has limited bandwidth, which poses a challenge for achieving full duplex in WiFi networks.
When a WiFi device transmits data, it uses a certain frequency channel within the available spectrum. In half duplex mode, the device switches between sending and receiving data, using the same frequency channel. This switching occurs rapidly, giving the illusion of simultaneous transmission and reception, but it is not true full duplex.
The Advancements of 3G and 4G
3G and 4G networks, on the other hand, operate in licensed frequency bands. These networks have dedicated channels for both upstream and downstream data transmission, allowing for true full duplex communication. The use of different frequency bands for upstream and downstream data ensures simultaneous transmission and reception without interference.
