Awaiting 3G

It's boom time for mobile phones in India. And people are looking forward to more information, faster data access and multimedia services through their mobile phones. 3G technology is here to turn this dream into reality. It's a technology anxiously awaited by telecom operations and subscribers in India.

How long do you have to wait?

Not very long! India is all set to launch 3G mobile telephone services by Jan 2009.

According to Telecom Regulatory Authority of India chairman Nripendra Misra, a total of 32.5 MHz is available for allocation within the next 6-9 months.

Trai has also recommended auctioning 200 MHz for broadband wireless access services like Wimax (worldwide interoperability for microwave access) and has proposed a national frequency management board to oversee spectrum availability and its efficient use.

He hopes that the allocated spectrum would be enough for the next two years and said Trai would recommend freeing up more spectrum for those who lose out in this auction.

So what is 3G spectrum all about? Read on.

What is spectrum?

Radio spectrum refers to a range of radio frequencies. The bandwidth of a radio signal is the difference between the upper and lower frequencies of the signal.

For example, in the case of a voice signal having a minimum frequency of 200 hertz (Hz) and a maximum frequency of 3,000 Hz, the bandwidth is 2,800 Hz (3 KHz). The amount of bandwidth needed for 3G services could be as much as 15-20 Mhz, whereas for 2G services a bandwidth of 30-200 KHz is used. Hence, for 3G huge bandwidth is required.

How is 3G different from 2G and 4G?

While 2G stands for second-generation wireless telephone technology, 1G networks used are analog, 2G networks are digital and 3G (third-generation) technology is used to enhance mobile phone standards.

3G helps to simultaneously transfer both voice data (a telephone call) and non-voice data (such as downloading information, exchanging e-mail, and instant messaging. The highlight of 3G is video telephony. 4G technology stands to be the future standard of wireless devices.

Currently, Japanese company NTT DoCoMo and Samsung are testing 4G communication.

How will 3G services help you?

3G services will enable video broadcast and data-intensive services such as stock transactions, e-learning and telemedicine through wireless communications

All telecom operators are waiting to launch 3G in India to cash in on revenues by providing high-end services to customers, which are voice data and video enabled. India lags behind many Asian countries in introducing 3G services.

What is Trai's recommendation on 3G pricing?

The Telecom Regulatory Authority of India has recommended auctioning radio frequencies for 3G telecom services at a reserve price of Rs 1,050 crore (Rs 10.50 billion) to companies seeking to offer nationwide high-speed Internet and streaming video.

The base price for spectrum in cities like Mumbai and Delhi and Category A telecom circles is Rs 80 crore (Rs 800 million); in cities like Chennai and Kolkata and Category B circles Rs 40 crore (Rs 400 million); and in all other cities Rs 15 crore (Rs 150 million).

What are the frequency bands and quota for CDMA?

Trai has recommended three sets of frequency bands - 450 mhz, 800 mhz and 2.1 ghz. For CDMA players like Reliance [Get Quote] and Tata Teleservices [Get Quote] 1.25 MHz each is offered. CDMA operators are free to bid both in the 2.1 GHz and the 450 MHz bands, but they will be allocated spectrum only in one. The pricing of these two bands is linked to the auction in the 2.1 GHz band.

CDMA operators will pay the same as the second-highest GSM bidder. And if there is more than one claimant in the 450 MHz band, the reserve price will be half of that arrived at in the 2.1 GHz band. Another rider is that if the highest bid is a quarter more than the lowest, the lowest bidder has to raise its bid to 75 per cent of the winning bid.

But CDMA operators are likely to face problems. Operating 3G services on 450 MHz is a problem because we they do not have dual-band phones that work both in 450 MHz and in 800 MHz (the band in which CDMA operates in India).

What are the issues regarding 3G for providers and users?

3G has successfully been introduced in Europe. But several issues continue to hamper its growth.

High spectrum licensing fees for the 3G services

Huge capital required to build infrastructure for 3G services.

Health impact of electromagnetic waves.

Prices are very high for 3G mobile services.

Will 2G users switch to 3G services.

Takes time to catch up as the service is new.

What are the issues regarding 3G pricing?

Pricing has been a cause of concern. Spectrum auctions ran into billions of euros in Europe. In Europe, spectrum licensing fees were collected years before the 3G service was developed and it required huge investments to build 3G networks, hitting mobile operators' margins.

However, in Japan and South Korea, spectrum licensing fees were not applicable as the focus of these countries were national IT infrastructure development.

Which companies have applied for 3G license?

3G spectrum has been provided to GSM players like BSNL, MTNL [Get Quote], Bharti, and Hutch to carry out an interface check on a non-commercial basis ahead of the start of 3G mobile services.

Trial spectrum has been given for a period of one month. This will be only 1/1000th of the actual 3G spectrum capability. Apart frm PSU majors, spectrum for carrying out 3G trials has been given to all those who have applied under the National Frequency Allocation Plan on the 2.1 GHz band. GSM players operate on 900 MHz and 1,800 MHz, while CDMA players operate on 800 MHz.

What is the pricing issue in India?

While Tatas have welcomed Trai's Rs 1,400-crore (Rs 14 billion) base price for a nationwide rollout of 3G services, the rest of the players find the price too exorbitant.

Bharti-Airtel is disappointed with the pricing as they were expecting it to be Rs 300-400 crore (Rs 3-4 billion). The reserve price is a disincentive for telecom companies in India. Bharti has appealed to lower the prices specially for rural penetration.

The Cellular Operators Association of India and the Association of Unified Service Providers of India are studying TRAI's recommendations and have not given their comments.

However, Trai chairman Nripendra Misra has said that there is no reason to worry as players will not bid exorbitantly and derail the auction. Misra said telecom operators had matured from their experiences and global developments, and would bid sincerely.

Where was 3G spectrum first introduced?

Japan was the first country to introduce 3G on a large commercial scale. In 2005, about 40 per cent of subscribers used only 3G networks. It is expected that during 2006 the subscribers would move from 2G to 3G and upgrade to the next 3.5 G level.

The success of 3G in Japan also shows that video telephony was the killer application for 3G networks. Downloading music was the biggest draw in 3G services.

In how many countries does 3G exist?

There are about 60 3G networks across 25 countries . In Asia, Europe and the USA, telecom firms use WCDMA technology. The WCDMA standard provides seamless global evolution from today's GSM with support of the worlds' largest mobile operators.

WCDMA technology is built on open standards, wide ranging mobile multimedia possibility, and vast potential economies of scale with the support of around 100 terminal designs to operate 3G mobile networks.

3G services were introduced in Europe in 2003

Strategy for Mathematics as an optional in IAS Exam.

Mathematics is amongst one of the most scoring optionals in Civil Services examination. This is the only subject which can easily give one 400 + marks like 431 scored by Pradeep Agrawal (Rank. 30, CSE 2005). Top 20 is always replete with candidates having Mathematics as their one of the two optionals. Topper of 2006 exam M. Veluraju also had it as one of his optionals. In the last decade Mathematics has produced maximum number of toppers. In last few years, popularity of Maths has declined little bit due to false propeganda against the subject . Along with Physics/ engg. subject, it can be safely opted as a first or second optional .
Who can opt for it
Apart from main stream Mathematics students, any one from engineering / Physics background can opt for it. Beauty of the Subject is its language / presentation neutral approach. Mathematics is truly regarded as language of Physics/ engineering disciplines, so it comes very handy to them.

What is against the subject ?.
Perceived notion of its time consuming nature, which is not true. This subject, by judicious planning can be easily prepared within 4 months like any other subject and believe me, if prepared well, Maths will never disappoint you.
Strategy for Mathematics in Mains Examination
Like any other optional, Mathematics in CSE comprise of two papers of 300 marks each. Each paper being divided into two sections of 4 questions each. Section A of paper I Comprise of the courses like Linear Algebra & Matrices, Integral & Differential calculus & Geometry of 2D & 3D. In this section if one prepares any two courses thoroughly , then one is preparing for minimum of 165 marks( 2 full questions and three bits) from the compulsory question. At the most one has to leave one bit from the compulsory question. Courses of Algebra & Calculus should not be omitted due to their linkages from the courses of paper II.

In Section B, we have the courses of Ordinary Differential Equations (ODE) , Vector Analysis & Mechanics. ODE and Vectors are regarded as simple courses, so normally “good “ questions are asked from them. These days more weight is given to their applied aspects . Therefore they should be well prepared from the Schaum series books by
M R Spiegel apart from standard books by Indian writers like diff. equations by M D Raisinghania / N M Kapoor/ Vector Analysis by J N Sharma. With . the latest revision of syllabus , syllabus of Statics/ dynamics has been trimmed . This portion is scoring and can be well prepared from Krishna Series (Meerut ) books
Strategy for paper II
Section A of paper II comprises of Modern Algebra, Real Analysis, Complex Analysis & Linear programming problems. Courses of Real Analysis & Calculus are overlapping, therefore one must definitely prepare for this course. According to prevailing opinion among experts, questions from Modern Algebra are short & scoring provided they have been adequately prepared & presented. Here help of good teachers like Prof. Ramakotaih (former V. C of Nagarjun University and having 45 years of teaching experience, associated with DIAS since last many years) proves very beneficial to students. From complex Analysis & LPP, one full question & two bits in the compulsory part are asked. One may prepare LPP question and may or may not prepare complex
Analysis part This way, If one prepares Modern Algebra, Real Analysis and LPP, then 3 full questions can be prepared from this section
Section B comprises of Partial differential equations (P D E), Numerical Analysis (NA) and Computer programming and .Mechanics and Fluid Dynamics.
P D E and NA being simple courses should be prepared .

Strategy for IAS Examination with CHEMISTRY as an optional “ Secret of scoring maximum marks in chemistry “

Careful study of Chemistry syllabus and pattern of recent year questions reveals that it is one of scoring subjects in Mains examination with minimum effort. One requires focussed approach. good selection of books, well understanding and proper guidance to score good marks in Mains examination.

How to Prepare for prelims Examination
In the syllabus of preliminary this subject has three sections. First section includes Inorganic Chemistry, second section Organic Chemistry and third section Physical Chemistry. All three sections have been given equal weightage and forty questions are asked from each section Prelims examination, requires thorough study of each section and each topic. One thing important here is that the questions asked in Prelims examination are new and based on the concept and generally not found in any book or study matter A deep and thorough study of standard books will help in this respect. Proper understanding and development of concept will definitely help to score good marks in this examination. Here, proper selection of books, guidance from a well experienced teacher and proper practice from previous year papers or from our study material be extremely helpful.
Suggested Reading for Prelims
1. Physical Chemistry – Puri, Sharma – Pathania & K.L. Kapoor Vol 1 to 4.
2. Inorganic Chemistry – J.D. Lee/Madan, Malik & Tuli,

How to Prepare for Mains Examination?
In Mains the whole subject is divided into two papers, First paper includes Physical Chemistry and portions of Inorganic Chemistry while second paper includes Organic Chemistry, Polymers and
Spectroscopy. For the Physical Chemistry part, a good understanding of the topics and proper presentation will fetch good marks. In Physical Chemistry for any derivation, all the assumptions, proper figures / diagrams, thorough analysis along with its practical applications will bring good marks. To elaborate it further ,I take here one example, say, the question is to derive Clausius- claypeyeron equation. In answering this question your approach shouldl be
Step (a) It is applicable only for one component- two phase system like- solid- liquid, liquid- gas etc.
Step (b) Mention the thermodynamic criteria of equilibrium.
Step (c) Write down thermodynamic relation of free energy.
Step (d) Write down assumptions in the derivation.
Step (e) Write down its usefulness and applications.
If one writes this way, he can score upto 80 percent marks in Physical Chemistry.
For Inorganic Chemistry, a thorough- understanding is required. Sometimes the questions asked in the Physical Chemistry part are not scoring enough and the questions asked in Inorganic Chemistry are scoring , therfore a good preparation of Inorganic
Chemistry will give you good marks. One thing is to be noted here if proper presentation is done one can score more in Inorganic Chemisitry than Physical Chemistry. Proper presentation, in–depth analysis along with examples will helpful in scoring more. For both Physical and Inorganic Chemistry, the question papers of previous years are very helpful and by solving the previous year papers under proper guidance one can score around seventy- five percent marks in Paper I.
Second paper includes Organic Chemistry, Polymer and Spectroscopy. Here strategy should be different. To score good in this paper proper understanding and linkages are necessary. Organic Chemistry is always a building and dynamic concept so daily revision, practice, discussion under proper efficient and effective guidance will be helpful. For building good concepts
in Organic Chemistry, in read Morison &Boyd and I.L Finar (vol) for basics. These books are also helpful in the Prelims examination. Now a days, question asked in the Organic Chemistry, are directly taken from standard books. So after building the concepts one must follow these advanced books thoroughly Previous year question bank is necessary but not sufficient. For sufficiency and gaining confidence in this paper, one has to do at least 50 good questions from each topic and in this respect our institute will be very helpful. If one does all the above things thoroughly, one can score upto seventy percent marks in Chemistry, For this, proper guidance, hard work revision and proper practice will be very useful.

Strategy for IAS Examination with PHYSICS as an optional Best Optional in Science/Engineering Group

Strategy for IAS Examination with PHYSICS as an optional
Best Optional in Science/Engineering Group

By D P Vajpeyi

Civil Services examination these days have become one of the toughest nuts to crack. Looking at the level of competition involved in this exam., one can sail through this ‘hurdle race’ in flying colours only by proper planning, hard work, perseverance and patience. Proper planning is must for getting good ranks in this exam. And first step in proper planning is right selection of optionals. In my opinion, optionals should be chosen on the basis of one’s interest in that subject, scoring pattern of that subject in previous few years, availability of study material and expert guidance.
First optional should be generally the subject studied during graduation/Post graduation. (There is no hard and fast rule in this regard, but my advice to the aspirants is that choosing “parent subject” as first optional proves beneficial, until and unless there are some very genuine points against that subject). And second optional should be chosen by applying the above mentioned four point criterion of interest, scoring pattern, availability of study material and expert guidance. On the basis of above criterion of choosing optionals Physics stands tallest amongst the Science/Eng. stream optionals. Reasons in its favour are:

1. Its well defined and well structured syllabus. It is least among all science/Engineering. Subjects.
2. Its scoring nature. Every year lot many Physics candidates make it to “Top-10”
3. Easy availability of study material.
4. Its reliable nature. If it has been prepared well one can easily score up to 60-75% of marks i.e. between 360-450 marks.
5. Highest success Rate of 12% among popular optionals

In spite of all above-mentioned factors, few people are creating an environment that these days Physics is not very scoring. You have to put lot of efforts to score “well” in this subject. So on and so forth. My answer to all these is that only those candidates do not score well in this subject who either leave many portions of the syllabus, do not give to-the-point answers or do not practice right way of answering the questions. A to Z of the present syllabus can be studied within 200 hours of study (this is the time, I take in Completing the whole course). Hence allegation of requirement of lot of time is not all that correct. Successful candidates every year score 400+ Marks in this subject. Therefore Science and Engineering Background candidates can safely opt for physics as their first or second optional.
PHYSICS AS AN OPTIONAL IN MAINS

Now let me discuss the nature of Physics question papers in Mains examination. Like any other optional, Physics too have two papers of 300 marks each. Each paper being divided into two sections of 4 questions each. And out of these 8 questions, one has to attempt only 5. First question of both sections being compulsory, meaning there by that one has to choose remaining 3 questions out of 6. (Good 50% choice). All questions typically have 3 bits each barring compulsory questions, where out of 4 bits one has to attempt only 3: This is the format of the question papers. Now let’s come to topic wise emphasis in both the papers.
Paper I comprises of (i) Mechanics (ii) Waves and Optics and (iii) Electricity & Magnetism and (iv) Thermal and statistical physics. Two full questions are normally expected from all the four sections. Bunching (Mixing) of questions is also possible. Therefore all the sections must be prepared. Each bit is of 20 marks and should be answered within 12 minutes.
Mechanics have four well defined topics: Particle dynamics, Rigid body dynamics, Mechanics of continuous media and special relativity. Two bits are expected from each topic. Hence you should not leave any topic. This course can be well prepared from text books of Mechanics by D S Mathur/ Kleppner and Kolenkov . From Special Relativity, at the most two bits may be asked. Hence all old topics like Lorentz transforms, Length contraction, time dilation, velocity addition, Mass-Energy equivalence are important.
In Waves, damped and forced oscillations, phase and group velocity should be given due importance. This portion can be prepared from any book because all topics are very common and given in all text books.
In Geometrical optics, Fermat’s principle and matrix method should be prepared well. Geometrical optics along with Physical optics can be prepared from book on optics by Prof. Ajay Ghatak. Physical optics also has three well defined topics providing one bit each. In interference, division of amplitude class should be prepared well, in diffraction topic of Cornu’s spiral should not be omitted and in modern optics, optical fibres, spatial and temporal coherence and lasers be given due weightage.
Electricity & Magnetism has two well defined topics of electrostatics/ magntostatics and current electricity. This course along with EM theory have been very straight forward and quite scoring. This course can be very well prepared from the books by David Griffiths/ Satya Prakash. Thermal and statistical Physics can be prepared from textbook by Garg, Bansal and Ghosh/ Satya Prakash.
Second paper of physics can be very well covered in 80-90 hours and therefore, if prepared well, can fetch rich dividends. Section A of paper II consists of Quantum mechanics and Spectroscopy, while section “B” has Nuclear & Particle Physics and Electronics & Solid state physics.
Whole of the second paper excluding electronics can be prepared from quantum physics by Resnick and Eisberg/ Modern Physics by Arthur Beiser. Above books can be supplemented by Quantum mechanics by H. C Verma, Spectroscopy by Rajkumar, and Nuclear physics by D C Tayal. Electronics can be prepared from text book by Allan Mottershed/ B. L. Thareja Vol. 4 and for solid state Physics, text book by Kittel is of immense help.
In Nuclear physics, semi-empirical mass formula, deuteron problem, Shell model of nucleus and theory of b-decay should be prepared well.
With the latest revision of syllabus, in paper 1, syllabus of Mechanics has been enhanced and questions are also expected from the topics like relationship between
Y, K and / Poiseuelle formula. Therefore due importance should be given to them. Among the courses of Paper II, electronics has maximum syllabus. Therefore non-electronics background candidates should make some extra efforts to master this part of syllabus or may also omit it.
This was all about different courses and their probable sources now I’ll give few general tips:

* My first advice is that one should not skip any portion of the syllabus. Thorough study is a must to get 400+marks at the most; one course could be omitted from both the papers. Although I do not recommend it.
* Analyse the examination papers of previous few years. You’ll know yourself where the focus is.
* Take practice tests and get them evaluated by a teacher and see yourself, what improvements can be made.
* While taking the exams, read the questions correctly. Your reply should be to the point, beating about the bush only wastes your time and doesn’t fetch you any extra mark. Units and terms used in formulas should be clearly explained.
* Do not give the derivation if it has not been asked. I’ll elaborate on this point, with the help of a problem asked in 2002’s exam. “Using rocket equation and its integral find the final velocity of a single stage rocket. Data for velocity of escaping gases is given”. In this problem, you may start from rocket equation, clearly explaining all the terms and then you may integrate it and obtain desired quantities. Here there is no need to derive rocket equation. Apart from wasting your valuable time it does not fetch you any extra credit hence this type of “extras” should be avoided.
* Finally one must stay ‘cool’ during the examination. Do not get panicky, even if you do not know few things.

Mr. D P VAJPEYI, B. Tech (IIT Bombay, M. Phil JNU) is the most popular teacher in Physics for Civil Services examination in India.

Coaching

Due to the complex exam procedure, the coaching assumes a crucial role. Unfortunately, it is a costly affair.

But the coaching has the following advantages:
• Helps in understanding the requirements of the exam quickly, so that the preparation is focused.
• Reduces the efforts in preparation, as subject experts teach the topics in exam orientation. Anyhow, the candidate has to prepare for at least one new optional.
• Helps in getting many contacts with co-aspirants, which is useful for exam related information. Never prepare for this exam in complete isolation. In any complex situation, information plays the key role.

Please take into account the following points while joining any institute:
• Do not merely go by the advertisements, nor the claims made in magazines or the interviews supposedly given by the toppers.
• Meet the successful candidates and the seniors who have taken coaching from that institute.
• Do not go by the advise of only one person. It is better to contact as many as possible and get a general opinion.
• Meet the teacher personally, ask for their programme details, results, etc, and assess yourself if it is worth joining there.

If you are working somewhere or economically under privileged, and therefore, cannot go for coaching, please do not get discouraged. There are many people who cleared the exam without coaching. You can device ways of getting the required information about the exam. But you should always be aware that you would have to work harder than others to clear the exam. So be prepared for that and believe that hard work will always be paid back in the end.

Check out the competition magazines to get the addresses of various coaching institutes.

Choosing the Optional Subjects

This is the first and most important stage of your journey and should be accomplished most carefully as coming things hinge on it and a wrong decision may prove to be disastrous. Careful analysis of syllabus, previous years' papers, your caliber, requirement of subject (Visionary, Numerical, Theoretical), comfort level with the subject and past trends should be done. Advice from seniors and fellow candidates should also be sought. To avoid dithering in choice at later stage, initial deep thinking and consultations are a must. Having decided the subject, it is advisable to stick to your choice even if the perception of others about it is not favourable.

Major criteria, which should guide you in choosing optionals, are:

1. Interest in the subject. This is quite important for sustaining the momentum in studies and completing the huge syllabus.
2. Availability of guidance – in the form of seniors who cleared with the optional, coaching, material, etc.
3. Performance of the optional in the last few years.
4. Time gap between the two optionals. Some people try to choose the optionals combination so that there is some time gap between them.

Please note that there is no subject that can be said to be scoring. UPSC is maintaining utmost balance between the subjects. It has brought all the optional subjects onto the same platform as far as scoring is concerned.

Some of the optionals which a majority take are: Anthropology, Geography, History, Political Science and International Relations, Psychology, Public Administration, Sociology and Literature.

The main advantages with these optionals are:

1. Availability of guidance, which reduces the efforts to a large extent
2. The knowledge also helps in GS, Essay and interview.
3. They are also relevant for an administrative career.

If a person is from professional education background (i.e. Engineering /Medicine), which optionals should he choose? This is a basic question for many. There is a tendency to opt for the graduating subject. Lets understand the problems associated with these subjects.

· Previously, science and Engineering Optionals used to do very well. In top 20, there used to be 15-16 from IIT and engineering background. But after 2000, UPSC has modified the syllabus. It became a very huge syllabus and even the exam questions are made tough. That’s the reason why, very few are writing the exam from IITs now. Many engineers are taking arts optionals instead of sciences. Just observe the background of the toppers and their optionals.

· There will be no guidance available for engineering/medical/science subjects. So, lots of time will have to be spent in understanding the requirements of the exam. Then, searching for the material. It becomes a trial and error process. All the energies will be spent on this, while you get exhausted when really studying. At the same time, you will also have to complete the huge syllabus of another optional and GS.

· Because of the above problem, it will take more time and more attempts. While, your friends in other fields go far ahead. So, both peer and social pressure starts. The exam is anyhow psychologically demanding, if other pressures add to it, then it becomes unbearable. Finally, your goal of cracking the exam becomes impossible.

· You will have to do every thing on your own. Initially it might be fine. But the exam is of long duration. It becomes difficult to sustain the momentum on your own.

A person might be University topper, but we have to understand the difference between an academic exam and a competitive exam. So it is very important to be careful, while choosing optionals, even though you might feel you are really good in a particular subject.

Still, if you are confident about your subject, then do take that optional. There are some people who cleared with optionals that others don’t take generally. But take into consideration the following points

• Whether you have a senior who has cleared with this optional and who can guide you well
• Whether you have close association with professors who have good understanding about this exam.
• Are you clear about the requirements of the exam? Study the previous papers thoroughly and assess yourself
• Be clear about the books to follow. Don’t do trial and error process. Do a focused exam oriented preparation.
• Do not neglect other optional and GS. Give equal importance.
• Form a group of aspirants with same optional. If you prepare in isolation, then there will be no flow of information.

Do not be in a hurry to decide about the optional. Be very cautious and consult the right people about the information. Analyse carefully all the pros and cons, and then take a decision purely based on your assessment.
