LTE stands for ‘Long Term Evolution’ which is used in the 4G networks to process data at more speed than the 3G network. In the earlier days before the evolution of VoLTE, it was the most used protocol for data communication for mobile users.
Be it downloading larger files, uploading or streaming videos——This telecommunication scheme gives faster data processing and continues to be a major network player even now in some regions of the world. In this blog post, We will briefly describe some facts on Lon Term Evolution.

What Is LTE or Long Term Evolution?
LTE is an acronym for ‘Long Term Evolution’ which is a wireless 4G standard to transfer data at higher speed for mobile phones and data terminals. Based on the previous GSM/EDGE and UMTS/HSPA, it uses different radio interface. It lets you download video, audio and upload files at faster rate than the 3G network. To work with efficiency and flexibility, the new standards for 4G Long Term Evolution emphasized to entail high spectral efficiency, high peak data rates, short round trip time and flexibility in frequency and bandwidth.
Features of LTE
- Long Term Evolution is a fourth-generation wireless standard with increased network capacity and speed to transmit data for mobile devices and data terminals.
- It offers higher peak data transfer rates than the third-generation network. Data transfer rate may be up to 100 Mbps downstream and 30 Mbps upstream.
- You can use to for voice over IP, Videoconferencing, streaming multimedia and high speed cellular modem.
- It provided reduced latency, scalable bandwidth and backward compatibility with GSM and UMTS.
- The network uses separate multiple-access technologies for uplink and downlink. In uses Orthogonal Frequency Division Multiple Access (OFDMA) for the downlink and Single Carrier Frequency Division Multiple Access (SC-FDMA) for the uplink.
How LTE Works?
The working mechanism of Long Term Evolution is different from the traditional GSM, UMTS and HSPA standards. It works on IP-based networks to transfer data with efficiency, reduced latency, scalable bandwidth and multiple frequency.
The old method like Global System for Mobile Communication(GSM) and Code-Division Multiple Access(CDMA) could transfer small amount of data but the modern Lon Term Evolution can transmit large amount of data as data packets to an Internet Protocol System(IPS). This network reduces transfer latency and allows data to move faster which facilitates upstreaming and downstreaming of videos, audios and larger files. Thus it increases the efficiency of 3G networks and even its is like 4G network. So, sometimes, Long Term Evolution is called 4G LTE. A mobile device will work on Long Term Evolution network if it lies within the range of the compatible frequencies, namely, 700MHz to 2.6MHz.
However, it does not work on 3G network. To work with efficiency, the compatible mobile device must have new hardware with supported spectrum. In the LTE network architecture, Radio Resource Controller(RRC) is ” the main driving force” , as it facilitates the sending and receiving of data over the network.
When Did LTE Evolve?
The development of Long Term Evolution is not all of a sudden. Before the development of this, GSM had global market in Asia and Europe. On the other hand, CDMA(Code-Dividion Multiple Access) was the major player in the U.S.A and Canada. Several companies in Europe and Asia tested and developed network specifications to operate Long Term Evolution.
It was 3GPP( 3rd Generation Partnership Project) that fully developed and standardized the specifications of LTE. It has full-scale development in 2008. Though before that a Japanese telecom operator DoCoMo, proposed for Long Term Evolution standards and worked on it. Besides, other renowned companies such as Nokia, Ericsson, TeliaSonera etc worked on it and finalized the project.
