4G or LTE: Everything you need to know!
The EPON OLT is a device serving as the endpoint for the service provider in a passive optical network. In other words, the Optical Line Terminal (OLT) manages the Ethernet Passive Optical Network (EPON). This technology offers multiple services thanks to its point-to-multipoint passive optical transmission.
1. What is 4G and 4G LTE?
1. What is 4G?
4G refers to the fourth generation of cellular network technology. It is optimized based on 3G and its performance is much better. 4G combines WLAN with 3G, making image transmission faster and clearer. The speed can reach up to 100Mbps. Currently, 4G is the general standard adopted by most people. 2G and 3G are being phased out. Although the emergence of 5G has hit the 4G market, it still occupies the dominant position.
2. What is 4G LTE?
LTE stands for Long Term Evolution, a technical standard for wireless data communication, which is created to constantly optimize cellular network technology to meet higher customer requirements.
LTE, an upgrade from 3G, is a transition between 3G and 4G. So LTE is also called 3.9G. Some companies may call it 4G LTE. 4G LTE is almost the same as 4G, but it's a little different. It is about 10 times faster than 3G and a little slower than 4G.
It improves the air access technology of 3G and adopts OFDM and MIMO as the single standard for the evolution of wireless networks. At 20 MHz, it can provide a maximum speed of 100 Mbps downstream and 50 Mbps upstream, which promotes user performance at the cell edge, improves cell capacity and reduces system latency.
2. Application of 4G and LTE
1. 4G CPE
4G CPE devices can transfer 4G LTE mobile networks over broadband and WiFi. In addition, 4G CPE can work as a multifunctional wireless router that provides broadband and WiFi to end devices. ELFCAM has developed a series of 4G CPE such as 4G LTE CAT4 CPE, 4G LTE CAT6 CPE, 4G Outdoor CPE, etc. These products are developed based on globally proven chip solutions and technologies, such as LTE CAT4, WiFi 4 Hotspot, Ethernet WAN/LAN, etc.
2. Online mobile games
The excellent performance of 4G promotes the rapid development of online mobile games. The stable and high-speed network gives users a wonderful experience when playing mobile games online.
3. Cloud Computing and Live
Before the emergence of 4G, Cloud Computing had high requirements in terms of human resources and costs. With 4G, efficiency has improved significantly. Live streaming is also booming and requires powerful communication technology as a medium. Exactly, 4G helps live streaming become more convenient and smoother.
Overall, 4G has improved the development of many aspects, including electronic devices, industry, quality of life, etc. Speed has improved significantly between 3G and 4G. Although 5G is also developing, and some 5G products are gradually emerging. For example, ELFCAM is also launching 5G CPEs capable of transforming 5G/4G signals into WiFi for use by nearby devices and performing secondary relaying for signals from operators' networks. But 5G only covers a few areas. 4G and 4G LTE are still very widespread.
