• 1. LTE stands for Long Term Evolution. It is
  successor of 3G UMTS and HSPA (HSDAPAHSUPA). 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.

• 2.LTE TUTORIAL-
• Here is a straight and simple tutorial is
  presented to learn 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 Indias only focused conference on
  LTE(Long Term Evolution) the Next Generation
  Wireless Technology LTE India 2013, 5th
  International Conference scheduled on 10th May

2. What is GSM ?

• GSM stands for Global System for Mobile
  Communication. Previously it was known as Group
  Special Mobile. GSM is combination of two
  multiple access technologies, TDMA ( Time
  Division Multiple Access) and FDMA (Frequency
  Division Multiple Access).

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 ?

• 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.

• 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.

5. DoT may invoke guarantees given by Airtel

• The Department of Telecom (Dot) intends to invoke
  bank guarantees given by service provider Bharti
  Airtel and has written to banks in this regard as
  the company has not paid Rs 350 crore penalty
  imposed on it for providing 3G services outside
  permitted areas in violation of rules.

6. What is Wimax technology ?

• WiMAX stands for Worldwide Interoperability for
  Microwave Access. Wimax is used for 4G wireless
  technology. It has also called 802.16 as per
  IEEE. WIMAX works similar as Wi-Fi but speed is
  greatly enhanced. Also WIMAX can serve greater
  distance rather than WI-FI and can serve to more
  users simultaneously than Wi-Fi.
