3G vs WiFi
[attachment=17073]
Introduction:-
The 3G network is the third generation of mobile networking and telecommunications. It features a wider range of services and advances network capacity over the previous 2G network. The 3G network also increases the rate of information transfer known as spectral efficiency.
Wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. The Wi-Fi Alliance, the organization that owns the Wi-Fi (registered trademark) term specifically defines Wi-Fi as any "wireless local area network”
What is 3G?
Based on the International Telecommunications Union standards, the 3G network is the third generation of mobile networking and telecommunications.
A 3G network provides for download speeds of 14.4 megabits per second and uploads speeds of 5.8 megabits per second. The minimum speed for a stationary user is 2 megabits per second.
Japan and South Korea were the first countries to successfully launch this network. The Japanese company FOMA launched in May 2001 and South Korea's SK Telecom launched in January 2002.
Delays on the roll-out process of the 3G network impacted the growth of mobile technology in many countries. This network uses a different radio frequency than 2G, which forced many companies to build entirely new infrastructure and obtain additional licenses.
How Wi-Fi Technology works.
The wireless adapter of a computer translates data into radio signals and transmits the signals over an antenna. The transmitting antenna is generally connected to a DSL (Digital Subscriber Line) or a LAN-based Internet connection.
The Wi-Fi signals have a range of about 120 feet indoors and 300 feet outdoors. With an increase in the distance between the user and the signal, the connection speed decreases. Wi-Fi connections allow you to get rid of the clutter of wires.
The use of Wi-Fi technology for Internet access is on the rise. Companies and households have begun opting for wireless Internet access.
