4G: Hold Your Excitement
In May 2010, while writing about the third generation (3G), I had stated that data-based services, including Internet, music, video or games, would rule the mobile market. Like everyone else, I, too, had great expectation from the 3G wave. Unfortunately, the 3G wave fell far short of our expectations. And, just when things started to improve a little bit, in terms of data speed and usage per subscriber, here comes 4G. 
 
While major operators like Bharti Airtel, Vodafone and Idea Cellular have launched their 4G services at several places, the most eagerly waited launch of Reliance Jio (RJio) is in the final stages of commercial launch. When the news last came in, Reliance Industries, the parent, had provided RJio SIM cards and devices to its employees who now can refer it to 10 people. I did a check on RJio data speed on a friend’s handset, but I am not impressed. The data speed was, indeed, much higher than 3G, but not even close to real 4G speed. This may be possible since my friend was using the mobile handset of another company rather than RJio’s LYF brand which the company recommends. I will surely write about RJio once it enters the commercial market with its 4G services through the long-term evolution (LTE) standard.
 
The main difference between 4G and previous standards, like 3G and 2.5G, is use of network nodes. Both, 3G and 2.5G, use packet-switched nodes for data services and circuit-switched nodes for voice calls. In 4G systems, the circuit-switched infrastructure is abandoned and only a packet-switched network is provided. Thus, in other words, in 4G, traditional voice calls are routed through Internet telephony.
 
In March 2008, the International Telecommunications Union-Radio communications sector (ITU-R) specified a set of requirements for 4G standards, named as International Mobile Telecommunications Advanced (IMT-Advanced) specification, setting peak speed requirements for 4G service at 100 megabits per second (Mbit/s) for high mobility communication (from trains cars) and 1 gigabit per second (Gbit/s) for low mobility communication such as pedestrians and stationary users. In short, the user of 4G should be able to get data speed of about 100Mbits/s.
 
Unfortunately, our experience with 3G is not that good. So, we need to take the claims of 4G data speed with a proverbial pinch of salt. One of the major reasons why the user never gets the 3G data speed as promised or advertised is lack of knowledge. Majority of users pay for 3G data service (denoted by H or HSPA+ or simply H+) but find that data network is always at 2G speed (denoted by E). The reason is that all mobile handsets are set on the default network setting of ‘GSM/WCDMA’ or ‘WCDMA Preferred’ that is nothing but 2G. Nobody informs the user to select ‘WCDMA Only’ in their mobile handset setting (for mobile network type) which is the 3G data setting. Try this; but there is no guarantee that you would receive the desired data speed. Anyway, since 3G is on its way out, let us not think much about the network and services.  
 
With the impending launch of RJio’s 4G across India, many think that it will finally change the usage patterns and help improve data speeds. In a test, Edelweiss found RJio beating other operators in terms of network speed. It found the data service of RJio much superior compared with incumbent players’ 4G services with indoor network speed of 3-8Mbps and outdoor speed of 15-20Mbps—about 25% higher than current operators. “However,” its report says, “superior performance can be attributed to RJio’s relatively empty network and performance may deteriorate post-commercial launch.” 
 
However, while we are getting ready for 4G, the next standard 5G is already being talked about, and is likely to be launched in 2020. Besides providing simply faster speeds, experts predict that 5G networks also will need to meet new use cases, such as the Internet of Things (network equipment in buildings or vehicles for web access) as well as broadcast-like services and lifeline communication in times of natural disasters.

While I agree that 3G network of most telecom operators (TSPs) is far from satisfactory even in metros, one expects better implementation of 4G from all TSPs, including R-Jio. Moreover, there are many instances of people having used VoLTE-based R-Jio's 4G network, which provides higher speeds compared to other TSPs, but one has to remember that R-Jio is yet to launch commercially, and with increase in subscribers, speeds are bound to drop. So, it's an unfair comparison with other TSPs for now. Moreover, the issue of Lyf handsets offering better speeds on R-Jio's 4G network needs to be sorted out by them, as unlike 2G or 3G, 4G comes in two flavours or standards - 4G which most TSPs have implemented, and 4G-VoLTE used by R-Jio. The latter is a new version of 4G tech, and carries both voice and data through internet protocols. So, if R-Jio adheres to industry standards on VoLTE, its speeds should be handset agnostic. If it indeed offers better speeds on its private-label brand Lyf handsets, then TRAI ought to take cognizance and ask R-Jio to ensure it complies with industry standards of 4G-VoLTE.
Moreover, there are few other mobile handset makers who offer 4G-VoLTE enabled phones now. There are plenty of options in the older 4G enabled phones by various brands though, but these won't work with R-Jio's SIM. So, when R-Jio launches commercially soon, its biggest challenge will be to push its Lyf handsets alongwith its SIM Cards. Currently its handsets are very expensive, compared to other brands which offer VoLTE-enabled handsets.

Nice Article. But can Relianc RJio prove to be an alternative to all these operators?
3G is an absolute Nightmare. Hopefully 4G live up to its expectations.

My experience is BSNL broadband on fixed line is the best of the lot. For speed of nearly 2-4 Mbps(billed as 8) upto 60GB for ₹1099 + taxes is the best

#Airtel advertises 4G in mountains/lakes/Forests etc. Sadly though in METRO CITIES, their Voice and Data drops like dirt. The data speed is not even closer to 2G. After all, in India, anyone can easily get away with #falseadvts. Some hope when Call drop fines were brought out ended in whimper ....

Airtel has been aggressively marketing their 4G services claiming that it is available in the nooks and corners of the country. I live in the city of Mangalore and I don't receive 4G services. When I consulted Airtel service, their technician visited my apartment on the tenth floor of a building, and told me that the height of my apartment is greater than the height of their mobile tower. Since the 4G signals don't move upwards, I must use 2G services only. I own a Lenovo K3 note phone. I am wondering if this reason is true?

Swachch Mind
Swachch Bharat, a passionate slogan given by prime minister Narendra Modi needs to be coupled with internal cleanliness to produce a new generation of Indians who live for others and Thena Thyakthena Bhunjithaha, that is, they rejoice in giving. For long-term results our educational system must internalise this external and internal cleaning into our curriculum. A clean India is a healthy India which, in turn, is a wealthy India.
 
All of us take a bath daily, maybe even twice daily, to get rid of the dirt, grime, germs and the all the unwanted things from our body’s outer surface to keep ourselves healthy. However, we never try and cleanse the mind which harbours more deadly poisons that could destroy us very easily. The mind is an integral part of the body and resides in every cell in the subatomic quantum level. This quantum concept of the mind explains many of the intricacies of the mind that were hitherto a mystery and did not come under scientific scrutiny. 
 
With advances in quantum physics comes the realisation that the mind (consciousness) is the one which observes everything—even in the most complicated scientific experiments. The human body has between 50-120 trillion cells, each of which has its mind on the cell wall with the antennae ready to receive signals from the universal consciousness (universal mind). While every human cell loves another cell in the body, these body cells also love other living creatures’ cells.
 
The mind, thus defined, is the source of all our thoughts that, in turn, direct all our actions. The mind does not reside in the human brain. There are basically two kinds of thoughts—positive and negative. While the former help the growth and development of the organism, the latter, the negative thoughts, are now known to be at the root of all our ills on this planet, beginning with the simple common cold to the deadly heart attacks, strokes and even cancer, the all-pervasive destroyer!
 
Study after study of the risk factor hypotheses has revealed the vital role played by negative destructive emotions on the major killers. The Johns Hopkins’ student study, the London White Hall study, and the Scandinavian study of men with heart attacks, showed the major role played by frustration, hostility and depression in this disease. Similarly, depression, with or without treatment, came up as the single most dangerous predisposing factor for growth and maintenance of cancers, with anger as the leading cause of stroke! The simple summary is that it is not what one eats that kills him, but it is what eats one that kills him.
 
Indian Yoga and praanaayaama are soaps for cleaning the mind. Regular physical exercise, especially outdoor walking, enjoying the bounties of nature en route would add to the perks. Diet enriched with fruits and vegetables could be an added bonus. Small regular meals, four to five times a day, help keep the internal environment within the limits of healthy fluctuations of the multifarious functions of the body.
 
Man lives for others. Helping others is the rent one pays for the comforts one enjoys in society. Molecular biology has taught us that even the thought of helping others brings on favourable changes in the cells of the immune system to prevent diseases! Praying for others is very effective as shown by a couple of well-controlled prospective studies done in the US. In addition, praying for others helps one to see life in a better perspective. It gives purpose to life and makes life worth living, avoiding depression. The latter is the greatest epidemic of the West these days. Breathe away to happiness and glory! Bath for the mind consists in daily replacing our negative thoughts, like hatred, greed, jealousy, anger and pride, with positive thoughts, like compassion, camaraderie, cooperation, empathy and enthusiasm to work and love.
 
“Cleanliness may be defined to be the emblem of purity of mind.” — Joseph Addison

IRDAI's e-commerce proposal to boost online insurance sales
Insurance companies on Saturday said the proposed guidelines on selling and servicing of policies through e-commerce platform are expected to boost online sales of insurance products.
 
The Insurance Regulatory and Development Authority of India (IRDAI) issued a proposed draft on Tuesday for promotion of e-commerce in insurance space and suggested introduction of an Insurance Self-Network Platform, a technology platform.
 
"We expect this (Insurance Self-Network Platform) will help in penetrating of insurance products. It is a revolutionary thing. The technology platform will induce lot of benefits to the customers in terms of accessibility of products that are not encouraged by agents due to lack of adequate remuneration for them," said Bajaj Capital group's CEO and Director Anil Kumar Chopra.
 
"The Insurance Self-Network Platform will undertake insurance e-commerce activities in India such as selling and servicing of insurance products," the draft said.
 
Chopra said the country's cumulative number of issued polices is about 12.5 crore which is abysmally low as compared to India's population. A single person should ideally have multiple policies for different covers like health, motor and life.
 
the state-run National Insurance Company is also exploring e-commerce selling and servicing.
 
"Online selling was there but it lacked proper guidelines. In online space, customers should be able to judge products not only on price point but also on the features and services offered by the company," said the company's Chairman and Managing Director K Sanath Kumar on the sidelines of the Insurance Summit organised by the Indian Chamber of Commerce.
 
"The online sales of policy without any requirement of physical signature process with an authentication process will help customers to buy property insurance and other term policies online at ease and they would not be influenced by agents," he said.

I am just waiting for the day when swimming would be taught through e-commerce.
Doing insurance would lead tons of policies getting time barred as normally the nominee is not aware of the policies taken either of the spouse. Person who could be intelligent will never go through e commerce. Who processes his nominees on claim on death? Employees of e-commerce site? I would always prefer to go online with the insurance co and his representative . Tall talks in the regulatory world is a fashion. Wait and see....
