1. LTE stands for “Long Term Evolution”. It is successor of 3G UMTS and HSPA (HSDAPA+HSUPA). LTE Advanced is one of technology in evolution from 3G to 4G. LTE was developed by 3GPP ( 3rd generation Partnership Project) . While HSPA and UMTS are 3.5G and LTE can be accepted as 3.99G and LTE advanced as 4G technologyAccording to 3GPP “LTE or the E-UTRAN (Evolved Universal Terrestrial Access Network) is the access part of the Evolved Packet System (EPS). The main requirements for the new access network are high spectral efficiency, high peak data rates, short round trip time and frequency flexibility.”

basics of LTE. Till the end of this LTE Tutorial course you will learn

What is LTE ? Architecture of LTE LTE in India:- LTE : Long Term Evolution, Which is the successor to UMTS and

HSPA is now being deployed by many network operators for high speed cellular services in India. 4G LTE has been launched in Kolkata, Bangalore, Pune & Chandigarh city by Airtel service provider. Many operators have not yet upgraded their basic 3G networks, and 3GPP LTE can be seen as the next logical step for many operators in India and all over World.

Overwhelmed and inspired with the success of previous LTE event series, Bharat Exhibitions is filled with enthusiasm to organize the 5th edition of India’s only focused conference on LTE(Long Term Evolution) – the Next Generation Wireless Technology – LTE India 2013, 5th International Conference scheduled on 10th May 2013 at Le-Meridien, New Delhi.

3. What is Cell and what is Cellular System ? A Cell is basic “construction block” of a cellular

system. One cell denotes geographical area covered by one trans-receiver. The actual size of cell depends upon several factors like the environment, Number of users and height of Antenna, Power of BTS etc.

In short we can say that cell is smallest radiating unit in mobile network.

A series of cells is used to cover a large geographic area. A cellular system is a mobile network distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station.

Each cell uses a different set of frequencies from neighboring cells to avoid interference

4. What is HSDPA ?4. What is HSDPA ? HSDPA : High-Speed Downlink Packet Access

HSDPA stands for high-speed downlink packet access. It provides faster download speeds. It is an upgrade form of UMTS.

HSDPA provides downlink data rate upto 7.2 Mbps.

HSDPA is High-Speed Downlink Packet Access and HSUPA is High-Speed Uplink Packet Access. Both together are called HSPA.

To be continue….To be continue…. Special Features of HSDPA Adaptive modulation and coding (AMC) Multi-code operation Hybrid Automatic Repeat Request (HARQ) Higher DL peak rates (up to 7.2 Mbps) De-centralized architecture where scheduling

functions are moved from the Radio Network Controller (RNC) to Node-B thus reducing latency and enabling fast scheduling.

In HSDPA Peak data download rate is increased significantly higher than 2Mbps. HSDPA is a new protocol for mobile telephone data transmission. It is known as a 3.5G (G stands for generation) technology which is up gradation

of 3G 3gpp release which is suitable for video calling and mobile TV.

4G stands for fourth generation of mobile telephony. It is successor of 3G standards where speed is highly increased.

4G technology is based on Open Wireless Architecture (OWA) which provides cost-effective and spectrum-effective high speed wireless transmission.

In March 2008, the International Telecommunications Union-Radio communications sector (ITU-R) specified a set of requirements for 4G standards, named the International Mobile Telecommunications Advanced (IMT-Advanced) specification.

According to these specifications 4G service will provide 100 Mbps for high mobility communication (such as from trains and cars) and 1 Gbps for low mobility communication (such as pedestrians and stationary users).
