What is LTE?
LTE stands for Long-Term Evolution. It is a 4G wireless Communication standard that provides high-speed data transmission for mobile devices. LTE is a significant advancement over previous 3G technologies, offering significantly faster download and upload speeds, lower latency, and improved Network capacity.
Key Features of LTE
- High Data Rates: LTE offers peak download speeds of up to 1 Gbps and upload speeds of up to 150 Mbps, depending on the network and device capabilities.
- Low Latency: LTE has a significantly lower latency compared to previous 3G technologies, enabling faster response times for interactive applications and online gaming.
- Improved Network Capacity: LTE networks can handle a larger number of users simultaneously, providing a more reliable and consistent user experience.
- Enhanced Voice Services: LTE supports Voice over LTE (VoLTE), which provides high-quality voice calls over the LTE network.
- Data-Centric Design: LTE is designed to prioritize data transmission, making it ideal for streaming video, downloading large files, and other data-intensive applications.
LTE Frequency Bands
LTE networks operate on different frequency bands, each with its own characteristics and coverage capabilities. Some common LTE frequency bands include:
| Band | Frequency Range (MHz) | Typical Use Cases |
|---|---|---|
| Band 1 | 2100 – 2170 | Wide coverage, good penetration |
| Band 3 | 1800 – 1900 | Wide coverage, good penetration |
| Band 7 | 2600 – 2690 | High capacity, good for urban areas |
| Band 20 | 800 – 850 | Wide coverage, good penetration |
| Band 28 | 700 – 800 | Wide coverage, good penetration |
