Long-Term Evolution (LTE) is a wireless broadband communication standard for mobile devices and data terminals based on the GSM/EDGE and UMTS/HSPA technologies in telecommunications.

It uses a redesigned radio interface and fundamental network upgrades to boost the capacity and performance of those standards.
Here are a few key points to note about how high-level LTE works:

• LTE potentially reduces latency and higher throughput across the network, significantly outperforming 3G.

• LTE uses a unique spectrum than 3G networks, necessitating the purchase of new gear.

• LTE offers data transfer speeds of several hundred megabits per second (Mbps), compared to several tens of megabits per second (Mbps) for 3G, making it 5-10 times faster than 3G.

• On smartphones and tablets, LTE may enable data, voice (VoLTE), instant messaging, and video all through a single interface
