Whats the difference between 1G, 2G, 3G wireless networking systems?

First, about cellular generations. 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.

In that sense, this NexTel trial is a 4G trial.

Makaravilakku heals millions

Truth or myth-Makaravilakku and Sabarimala heal many. Let it carry on. Sabarimala pilgrimage is a saunter into the Nature.

Keep open Sabarimala shrine on all days.

The stampede at the Sabarimala shrine in which 104 pilgrims have died indicates that human life is a commodity for Rs 5-6lakh. The money that received by the family of ill-fated pilgrims says we do not value human life that much. Lack of proper schedule for the travel of people to Sabarimala is the root cause of the grave mishap.

To avoid the heavy rush at Makaravilaku season why can’t Devaswom Board make arrangement for keeping the Sabarimala temple opened all the days in a year instead limiting it to 41 days or less. Why the heap of camphor burned at Ponnambalamedu on Makaravilaku day alone? Can’t it be performed a dozen days in a year on other holy days so that pilgrims get more opportunity for a healing thought by viewing it? Again worshippers hating large crowd could also advantageously visit Sabarimala at their pace if the temple is kept opened on all days.

Sabarimala is small area and that is not meant for for huge crowd. It is located at a remote hilly place where easy accessibility is difficult. The government has not provided scientific traffic management despite the huge sum received from the pilgrims as donation and travel fare.

It is better to have an introspection for the people of Kerala than accusing one and the other.

The sky is the limit

The success or failure of a space mission depends on many factors. The probability of successfully launching a satellite can't be predicted. That's the reason not too many people are criticising the recent failure of the GSLV satellite. The scientists must focus on rectifying technical snags. More than Chandrayaan, India needs more space projects that improve our communication network facility. Chandrayaan can only fetch data already available with Nasa or
similar agencies.

Do we need more engineering seats?

May be a pleasant surprise for students but is quite unlikeable for the conventional arts and science colleges in the country, Human Resource Development Minister Kapil Sibal’s announcement of increase of 200,000 seats in engineering courses in India. Already some of the Engineering Colleges in TN and Karnataka are in the verge of collapse due to poor inflow of students and one wonders what prompted Sibal to sanction this much seats in Engineering sector. The huge infrastructure now available with Arts and Science Colleges are poorly utilised at present due to unattractiveness in pursuing conventional education and the present decision of the government would turn the issue worse.

The liberalised scheme now applied to Engineering colleges would not bring results as the minister expect. More focus on technical education would result in lack of interest in pure science study.

Abandon NCERT Physics text books for Plus 2

I am a retired Physics Professor (?) of an affiliated college under University of Kerala and lecturer for many years in graduate classes and erstwhile pre-degree course and still keep some interest in the subject physics. I had already shaped half a dozen First Ranks in B Sc Physics (main) of University of Kerala and hence I believe that I have a few credentials to speak about Physics. My present apprehension is about the prescription of NCERT text books for plus two classes in State Higher Secondary and CBSE schools. The present form of NCERT text books in Physcis would certainly bring hatred among students towards the much lively subject-the physics. Presumably the writers of the present text have no class room experience otherwise they have not presented the subject matter in form of ‘water flood’. What the students get from these text books is little and that is why most teachers use credible text books instead of referring the NCERT text book waste. The teachers ask students to buy NCERT books and never refer to these books while teaching. The teachers have little time to squander by reading all the rubbish in the NCERT books. I sincerely believe those writers of the text book never had been so if they had been asked to follow these text books in their school classes. Though the NCERT claim that their text books are written in conformity international standards, the presentation in foreign books are not so dreary.

The NCERT text book committee may also claim that their books would generate independent thinking among students. This sort of argument is applicable to elite classes. How can a low profile student from a poor family, unable to spell his name correctly in English even in Plus 2, without knowing the basics of Physics, think independently about new rules and ideas in Physics? The government should, therefore, reduce its control on what text book to be followed in schools and teachers and students should be given freedom in following text books.

My suggestion to the Union Human Resource Development Ministry is, ask NCERT to prescribe syllabus and not to write text books or rather compel students community to follow their text books. They can of course supply sample question paper packets and answers to students to augment their studies. The NCERT could, of course, recommend any other suitable text books to school children and if the contents are found to be prejudicial to the integrity of India or the security of the state, the books can be withdrawn. Though the present NCERT text book in Physics does not defame any community, it invites hatred to the subject Physics. Let the students learn Physics pleasantly and lively.

All teachers’ appointments should be done by the P S C.

Good news to hear that PSC would now carry out the appointments of staff in Universities in Kerala. The decision by the Cabinet is presumably in the backdrop of discrepancies relating to the appointment of the assistants at the university level. Why, then wait for appointment of teachers in University Departments by the P S C. Is it now alright with the appointments in University departments? Are the P S C members appointed on political basis are not competent enough to recruit to the teachers to the Departments.
All appointments including teachers of private colleges where salary is paid from State Exchequer should be transferred to the P S C. The private college managements should not be permitted to sale these posts for a price.

Verdict against caste politics.

How miserably the politicians read the public mind, is evident from outbursts of Lalu Prasad Yadav and Ram Vilas Paswan a day before the election results in Bihar.
They claimed a big leap for them in the Bihar Election but unfortunately it was a big blow. NDA leader and CM Nitish Kumar has driven to a remarkable electoral feat by securing 84 percent of the seats in the Bihar Assembly. Lalu, Paswan et al can go to hibernation for next five years and the National Congress leaders have nothing to cheer. Who said the Bihar people are illiterate and are guided by malicious propaganda?

Those who fought the election on the basis of caste in Bihar had been defeated and it is a direct warning to those who resort to caste politics in rest of the country.

Quick bucks for private colleges!

Many of the affiliated colleges in Kerala are in killing spree in disguise for the appointment of teachers to their various faculties. One of the major handicaps the managements face with, is the lack of NET/JRF qualified candidates with liquid cash in tune with 20 or 30 lakhs. Then, came news from some flip-side doors of the UGC stating that candidates with M Phil can also apply for the posts. On hearing this there was a heavy rush for purchase of application forms from the office-counters of private colleges and it attracted some quick bucks to the managements. The managements were also happy of getting an immediate fortune without much hardships. If demand is high the auction amount is also high.

But unfortunately, soon arrived a clarification from the UGC that candidates should be NET qualified for appointment, sending the management to an immoderate despair. However, the Mundassery II of Kerala is contemplating to dilute the UGC stipulations in collusion with all gluttonous managements.

Will the Managements pay back the application money in tune with Rs 500 or 750 they collected from candidates for one-day clearance sale of application forms? Will the Government check up the rank lists of candidates waiting for appointment in these colleges? Is there any management in Kerala, still waiting to appoint from their lists because of non-compliance of candidates with adequate fund? Will the Government ask private college managements to publish the rank lists on their website, as PSC do, on the very next day after the interview? There should be some corroboration in the acts of private college managements in Kerala because salary to the privileged ones appointed in these colleges, are paid from State exchequer.

Good news from Myanmar

Report from Myanmar is a matter of relief for the rest of the world. Aung San Suu Kyi has been released by the military rulers of Myanmar. Presumably she could lead her party for the imminent Myanmar general election if the military rulers do not impose further restrictions. Most probably Myanmar’s calming posture by releasing Aung San Suu Kyi was the outcome of U S President Barack Obama stance on the issue. Obama has personally supported for the release of Aung San Suu Kyi during his recent visit to India.

It is good for Myanmar if the rulers of that country so decide to demonstrate faith in Democracy and thereby to avoid further diplomatic isolation from all world countries.

‘Poet from the gutters’ does not need ceremonial firing.

The ‘poet of the orphans’ has to wait one more day in cold storage for his last rites. Election to local bodies and the inconvenience of the cultural minister, are the reasons for the delay! Undoubtedly it is an insult to a dead man’s corpus. It is quite distressing to see that poet Ayyappan has to tranquilly wait to get opened his way to ‘ Santhikavadam’ and there from to eternal joy.

Hereinafter, celebrities who wish to die, die only after consultation with the cultural stalwarts of Kerala. Who said the ‘poet from the gutters’ need ceremonial firing from shot less guns?
