What is 2G spectrum?

2G (or 2-G) is short for second-generation wireless telephone technology. Second generation 2G cellular telecom networks were commercially launched on the GSM standard in Finland by Radiolinja (now part of Elisa Oyj) in 1991. Three primary benefits of 2G networks over their predecessors were that phone conversations were digitally encrypted; 2G systems were significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS text messages.

2G and Scam

What is 2G?

2G is the abbreviation for Second Generation wireless telephone technology. The main benefits of 2G are that phone conversations are digitally encrypted. 2G systems are far more efficient on the spectrum allowing for greater mobile phone access levels, 2G also introduces data services for mobiles.

What is spectrum scam?

From the time of charge of misuse during the bidding for allocation of 2G spectrum surfaced, till Telecom Minister A. Raja's ouster, high drama charged both politics in Delhi and Tamil Nadu. • Spectrum scam cost the government ₨. 1.76 lakh crore • 2G licences issued to private telecom players at throwaway prices in 2008 • Rules and procedures flouted while issuing licences

The charges on Former Telecom Minister A. Raja

Cheap Telecom Licences:

• Entry fee for spectrum licences in 2008 pegged at 2001 prices • Mobile subscriber rates had shot up to 350 million in 2008 from 4 million in 2001

None of the procedures were followed:

• Rules changed after the game had begun • Cut-off dates for applications were advanced by a week • No proper auction process was followed and no bids were invited • Raja ignored advice from TRAI, Law Ministry, Finance Ministry • TRAI had recommended auctioning of spectrum at market rates • Licences were being issued on a first - come - first - served basis

The opposition further stepped up its attack with two examples on 2G auction:

A new player, Swan Telecom, bought licences for 13 circles with the necessary spectrum for $340 million but managed to sell a 45-percent stake in the company to UAE's Etisalat for $900 million. This swelled its valuation to $2 billion without a single subscriber.

Out of the 122 new licenses that were given out, 85 licenses were won by companies that did not meet the eligibility criteria. Six of the Unitech group companies which applied for licenses for 20 circles did not meet requirements.

Parties accused because of their involvement

The selling of the licenses brought attention to three groups of entities - politicians and bureaucrats who had the authority to sell licenses, corporations who were buying the licenses and media professionals who mediated between the politicians and the corporations.

Politicians involved

§ A. Raja - the Minister of Communications and Information Technology who sold the licenses

§ M. K. Kanimozhi - Rajya Sabha MP

§ P. Chidambaram - The Then Minister of Finance and current Minister of Home Affairs - alleged to be involved with A. Raja in spectrum pricing and equity dilution by telecom operators that received spectrum

Bureaucrats involved

§ Siddharth Behura - Former Telecom Secretary

§ RK Chandolia - Raja's private secretary

Corporate Executives involved

§ Gautam Doshi - Managing Director of Reliance Anil Dhirubhai Ambani Group

§ Surendra Pipara - senior vice- President of Anil Dhirubhai Ambani Group and Reliance Telecom

§ Hari Nair - senior vice-president of Anil Dhirubhai Ambani Group

§ Sanjay Chandra - Managing Director of Unitech Wireless (Tamil Nadu) Ltd

What is the meaning of a 2G spectrum?

It is a term used in the telecommunication sector. It is a spectrum that supports 2G technology. High bandwidth is required for this purpose.

"2G" means second-generation wireless telephone technology. 2G cellular telecom networks were commercially launched on the GSM standard in Finland in 1991.

"G" has been superseded by newer technologies, such as 2.5G, 2.75G, 3G, and 4G; however, 2G networks are still used in many parts of the world.

There are three primary benefits of 2G networks over their predecessors: phone conversations were digitally encrypted; 2G systems were significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS text messages.

Is 3g mobile better than 2g mobile?

The answer to this question depends on what specifically one is looking for in a phone. If one is to consider price alone, a 2g phone is definetely better since it tends to be cheaper. However, the 3g phone submits data at a higher speed, can support video-conferencing, has better audio and video streaming and even allows one to watch TV through the internet. If price is not a major factor, the 3g phone is better than the 2g phone.

What is the difference between 2g and 3g technology?

2G is the GSM specification used to enhance the mobile whereas 3G communications is used for mobile users to have communication over voice with added Multimedia Applications with proportionate speed as well..,http://bit.ly/ouNC5C

First, about cellular generations. Having worked in the industry for a while, I have a narrower view what 1G, 2G, 3G, 4G, etc. mean. First 1G service was based on a TDM voice infrastructure -- built around class x switches and 64 kbps slots. It had data, but circuit switched over a 64Kpbs voice bearer.

Second, 2G service had the same switched TDM backbone, but added a true Data Bearer and a digital voice bearer. Data rates were still limited to the max 64kbps of a single time slot.

2.5G added a packet bearer to the mix, still limited to 64kbps slots.

Third generation (3G) changed the backbone slightly to allow a full T1 or E1 or J1 to be consumed by a data sub-scriber, but is still based on an ISDN style backbone. Sure you have packet switched data, but its carried over a traditional TDM backbone. There still a circuit voice backbone and while the data rates are high enough for VoIP, the latency of the data service is to great to base all of the "bearer services" on it, so you still have circuit voice, circuit data and packet data bearers.

Finally, 4G systems will utilize a packet infrastructure rather than a traditional telephone architecture. Services will be horizontally layered on top of a proper low latency, QoS enabled packet switch (read IP) infrastructure. Gone will be the circuit voice and circuit data bearers.

So "G" has more to do with the infra-structure and less to do with the data rates. The data rates over the air are driven by the organization of the infrastructure and other than that have little to do with what generation they are.

What is 3G in telecom?

International Mobile Telecommunications-2000 (IMT-2000), better known as 3G or 3rd Generation, is a family of standards for mobile telecommunications fulfilling specifications by the International Telecommunication Union,[1] which includes UMTS, and CDMA2000 as well as the non-mobile wireless standards DECT and WiMAX. While the GSM EDGE standard also fulfils the IMT-2000 specification, EDGE phones are typically not branded 3G. Services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment. Compared to 2G and 2.5G services, 3G allows simultaneous use of speech and data services and higher data rates (at least 200 kbit/s peak bit rate to fulfill to IMT-2000 specification). Today's 3G systems can offer practice of up to 14.0 Mbit/s on the downlink and 5.8 Mbit/s on the uplink.

What is the difference between 1G 2G and 3G mobile?

first of all, its not hard to understand, you'll just have to imagine how data flows in the air, in what way, and how fast.

1G is the first generation celullar network that existed in 1980s. It transfer data (only voice) in analog wave, it has limitation because there are no encryption, the sound quality is poor and the speed of transfer is only at 9.6kbps. IT IS STILL IN USE in some country by police, taxi cabs, telephone company.

2G is the second one, improved by introducing the concept of digital modulation- which means converting the voice(only) into digital code(in your phone) and then into analog signals(imagine that it flys in the air). Being digital, they overcame some of the limitations of 1G, such as it omits the radio power from handsets making life more healthier, and it has enhanced privacy

There are 2.5G, which is a transition of 2G and 3G. In 2.5G, the most popular services is the SMS (short messaging service). Of course there are something else like GPRS, EDGE, High Speed Circuit switched data, and more.

For 3G, imagine 2000+kpbs data rates, its not only voice and simple data(message) that be transmit, services such as downloading, video calls, mobile TV, mobile Internet are available.
