Smartphones in nowadays are getting smarter like their name. In 2015 maybe you are familiar with the word 4G or 4G LTE. Many smartphones manufacturers are listed this in their smartphones specifications and some new big products of smartphones manufacturers, like the samsung galaxy S6. So, what actually 4G LTE is ?
LTE, an abbreviation for long term evolution, commonly marketed as 4G LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM / EDGE and UMTS / HSPA network technologies, increasing the capacity and speed using a different radio interface together with core network improvements. –source
The goal of developing 4G LTE is actually the same with the development of 3G in the past, to increase the speed of the wireless data of your gadget, so you will enjoy a high speed connection. The LTE specification provides downlink peak rates of 300 Mbit/s, uplink peak rates of 75 Mbit/s and QoS provisions permitting a transfer latency of less than 5 ms in the radio access network. LTE has the ability to manage fast-moving mobiles and supports multi-cast and broadcast streams. LTE supports scalable carrier bandwiths, from 1.4 MHz to 20 MHz and supports both frequency division duplexing (FDD) and time division duplexing (TDD). The IP-based network architecture, called the evolved packet core (EPC) and designed to replace the GPRS core network, supports seamless handovers for both voice and data to cell towers with older network technology such as GSM, UMTS and CDMA2000. –source
In simply world, as like the Google said, LTE network users can enjoy data speeds 10 times faster than the current 3G network. With up to 300 Mbit/s download speed and up to 75 Mbit/s uplink speed, you will easily take all of what do you need in your download list, but this will be different from one provider to the another provider.
Also, this LTE offers an enhancements in your calls. Your phone call will have a better sound quality.
