What is 4G?
Frequently Asked Questions
The next generation of mobile technology standards, 4G is the latest buzzword for smartphone and tablet users. 4G succeeds the third generation (3G) standards and provides ultra-broadband Internet access, which opens the door to high-definition mobile TV, video conferencing and cloud computing. Initial 4G candidates include the Mobile WiMax standard and Long Term Evolution (LTE), although some debate exists as to whether these systems qualify under official standards.
The International Mobile Telecommunications Advanced specification requires 4G services to transmit data at a peak rate of at least 100 megabits per second for high-mobility communication (from cars and trains) and 1 gigabit per second for low-mobility communication (stationary users). LTE Advanced is an IMT-Advance compliant network that delivers the required speeds. Along with increased speed, 4G technology offers an abundance of performance-focused improvements. 4G networks use multiple-input and multiple-output (MIMO) antennas to improve communication performance. This form of smart antenna technology increases data throughput and link range without additional bandwidth. 4G technology also features adaptive links with error-correcting codes for fewer bugs. Users may not be able to pinpoint some of the changes under the hood, but 4G offers an overall improved mobile experience.
On the surface, 4G technology is yet another step forward in terms of performance. Users will experience browsing speeds comparable to Wi-Fi networks, and with so much available bandwidth, they will be able to take advantage of cutting-edge tablet and smartphone features that would bog down lesser networks. Older-generation networks are not obsolete, but 4G is the pinnacle of mobile performance in the current market. Whether you are looking for increased browsing speeds, higher video-call quality or clear mobile TV signals, 4G will deliver the best performance in any circumstance.
Short for fourth generation, 4G is the mobile communication technology standard that succeeds 3G. When 3G hit the market, it offered increase speeds and higher bandwidth. 4G takes these standards to the next level, raising the bar in terms of mobile device performance.
IMT-Advanced specifications set peak speed requirements for 4G services at a minimum of 100 megabits per second for high-mobility communication and 1 gigabit per second for low-mobility communication. 3G standards require providers to transfer data at peak rates of at least 200 kilobits per second. The significant speed boost associated with 4G opens the door for better call quality, faster browsing, clearer video calls and even high-definition mobile TV.
3G networks raised the level of personal security, replacing the A5/1 stream cipher with the more reliable KASUMI block cipher. 4G retains its predecessor’s security standards, but with additional key features. Multiple-input and multiple-output (MIMO) antennas increase the data throughput and link range without adding bandwidth. This means improved communication performance and more reliable coverage. 4G technology also features error-correcting codes that minimize bugs. 4G and 3G offer varying levels of performance. Both are reliable for basic web browsing and app use, but 4G outshines its predecessor on more complex functions.
The fourth generation of mobile communication standards, 4G offers increased speed and advanced performance features. On a 4G network, users can access advanced mobile features such as video calling, mobile TV and high-bandwidth apps without reliability concerns. 4G offers top-end service for tablet and smartphone users who rely on their devices throughout the day.
IMT-Advanced requirements specify that 4G networks must deliver a peak speed of at least 100 megabits per seconds for high-mobility communication and 1 gigabit per second for low-mobility communication. This is a significant jump from the 200 kilobit per second standards assigned to 3G networks. Along with this speed boost, 4G also delivers unprecedented performance features. 4G networks use multiple-input and multiple-output (MIMO) antennas to increase data throughput and link range. Link adaption automatically corrects coding errors to reduce the amount of bugs. You may not be able to pinpoint how, but 4G raises the bar for performance and user experience.
Eventually, users will all experience these speed and performance standards, but right now, 4G is an advanced alternative to lesser services. Users can complete basic smartphone and tablet functions without this increased performance, but 4G coverage can handle the more complex mobile functions hitting the market. As you shop for your next tablet or smartphone, consider the benefits of a device that can support this advanced network.
