LTE vs. 4G: A Deeper Understanding of the Differences
Although LTE (Long Term Evolution) is often referred to as 4G, it is actually just a technology that is evolving towards 4G. LTE significantly improves network speed and efficiency relative to 3G, but there is still a gap in meeting the true 4G standards set by the International Telecommunication Union (ITU). True 4G networks can provide higher speeds, lower latency and greater carrying capacity.
What are GSM, 3G & 4G?
GSM (Global System for Mobile Communications) is a 2G mobile communication standard used worldwide and is the foundation of modern mobile communications.
As technology evolved, 3G (third generation mobile communications) came into being, providing users with faster data transfer speeds and richer multimedia services.
4G (fourth generation mobile communications) built on this to achieve ultra-wideband connections, meeting the needs of high-definition streaming and high-speed Internet access.
What are the frequencies of GSM, 3G and 4G?
– GSM typically operates in the 850 MHz, 900 MHz, 1800 MHz and 1900 MHz bands.
– 3G frequencies vary by region, with commonly used bands including 850 MHz, 900 MHz, 1700 MHz and 2100 MHz.
– 4G/LTE covers the 700 MHz to 2600 MHz bands, which allow users to enjoy faster speeds and higher quality of service.
Is LTE superior to GSM?
Yes, in terms of overall performance, LTE is significantly better than GSM in terms of data transfer rate and bandwidth utilization efficiency. However, as a mature technology, GSM still plays an important role in many areas, providing reliable voice calls and basic data services. As technology continues to advance, understanding these differences will help you make more informed decisions about equipment selection and privacy protection.
