Summary
Wireless networks 3G and 4G are compared and contrasted. Students learn about the differences between 3G and 4G networks, and between 4G LTE, 4G WiMax, and 4G WiBro networks.
3G and 4G services
3G and 4G wireless networks offer similar services. 4G is faster than 3G. 3G and 4G networks use different technologies. 3G uses packet switching for data and circuit switching for voice. 4G networks will integrate wireless and wired technologies.
Network architecture
The architecture of 3G networks is described. 3G networks have a base station, a radio network controller, a Serving GPRS support node and a Gateway GPRS Support Node. 4G networks will enable users to roam across different communication systems. 4G networks will involve changes in the user’s experience.
4G LTE, WiMax, WiBro
4G LTE, WiMax and WiBro networks are compared. 4G LTE is the fastest, followed by 4G WiMax and 4G WiBro. 4G LTE and 4G WiMax have different upload and download speeds. 4G LTE and 4G WiBro have different backward compatibility. 4G LTE and 4G WiMax have different service availability.
4G competition
Competition between 4G LTE carriers is fierce. The benefits of this competition to the subscribers are described. The coverage of Verizon and AT&T is compared.
