Why not leapfrog 3G TO 4G?

1. It has actually been veri long hearing about Indian Government trying/deciding to start the 3G Spectrum allocation. Finally few decisions have been made in last few weeks and something has been done in a limited capacity.Now till the time this limited capacity becomes ready to take on fully operational 3G Services across India,3G will be without doubt an obsolescent and old technology at global level.The amount of infrastructure,investment,time and loads of effort that will be sucked in by this 3G setup is likely to go in waste considering the thirst everywhere to be at par with the latest in communication.3G may look good today when we are not aware of 4G Technology.For those who are interested to know about 'G' family in brief,pls click here.

2. So,still when the exhaustive details on spectrum auction are awaited,why not leap frog to 4G thus vamoosing the extraordinarily delayed 3G for attaining higher data speeds to finally allow users in India to experience the "state of art speeds".

1. At an earlier post here, I had discussed about the upcoming OSs incl Barrelfish,Midori,Helios etc likely to be introduced by Microsoft in near some thing from leaked (which valve actually faltered …no one knows?) source on the net about processors from INTEL,three quad-core Clarksfield processors, the i7-720QM, i7-820QM and i7-920XM, clocked at 1.6GHz, 1.73GHz and 2GHz can be expected by the end of this year

2. Low voltage chips including 25W 2.26GHz Core i7-660LM,1.46GHz Core i7-680UM and 1.33GHz Core i5-560UM with an overall aim to enhance the battery life while end Dec 2010 will see high-end Core i7-680UM that starts at 1.46GHz and speeds up to 2.53GHz and a 1.33GHz / 2.13GHz Core i5-560UM, plus a 25W 2.26GHz Core i7-660LM low-voltage chip will also see the year 2010. All these will have on-die Intel HD Graphics .

3. Another 32nm "Huron River" is likely to make it to the user shores by early 2011 which will single handedly handle WiMAX, WiDi and Intel Bluetooth alongside new concept dubbed Zero Power ODD which promises a power-saving sleep mode for optical disks drives.

'Microrings' - Ultimate Wireless Communication

1. Researchers based in Purdue University have developed a miniature device capable of converting ultrafast laser pulses into bursts of radio-frequency signals, a step toward making wires obsolete for communications in the homes and offices of the future.Such an advance could enable all communications, from high-definition television broadcasts to secure computer connections, to be transmitted from a single base station, said Minghao Qi, an assistant professor of electrical and computer engineering.The team fabricated tiny silicon "microring resonators," devices that filter out certain frequencies and allow others to pass. A series of the microrings were combined in a programmable "spectral shaper" 100 microns wide, or about the width of a human hair. Each of the microrings is about 10 microns in diameter.

2. Thus a single base station would be sort of a computer by itself, perhaps a card inserted into one of the expansion slots in a central computer. The central computer would take charge of all the information processing, a single point of contact that interacts with the external world in receiving and sending information."There is no end to i say.....just when we thought WiFi is the end of home trouble shootings for easy connectivity...this goes many steps ahead.....

WiFi Amplified 10 times : Here comes WiGig™

1. WiFi,the term that has revolutionised our lives at home with ease of access and mobile internet connectivity is all set to receive a major boost in speed when the 60GHz frequency band comes into operation. Wi-Fi Alliance® confirmed an alliance with WiGig™ to expand the current WiFi band range. Current WiFi technologies will remain, with the new 60Ghz range coming in to compliment these already existing technologies. 60 GHz device connectivity will be an exciting enhancement to the capabilities of today's Wi-Fi technologies. It will expand the utility of Wi-Fi, used by hundreds of millions of people every day.The goal - to bring 7Gbps wireless connectivity to users!!!!

2. How does this happen? Basically transfer speeds that are 'turbo boosted'. Today maximum data transfer speeds are in the region of about 150 Mbps. Bringing in this new technology will boost that figure to anywhere between 1 Gbps to 7 Gbps. That is about 10 times faster than the norm today. On the flipside, higher frequency waves don't have the range of current lower frequencies, and the 60 Ghz band travels in a straight line, meaning one would need line of sight between two devices to transfer data.

3. Estimates are that this technology will be available in devices that have dual-band or tri-band capabilities, in approximately two years. These devices will most likely have the ability to switch between the current 2.4 Ghz or 5 Ghz, and the 60 Ghz band.


1. Ever heard of google's street view application...m sure many of you must have...for those who have not heard of brief it refers to a technology featured in Google Maps and Google Earth that provisions isometric views from various positions along many streets in the world. Launched on May 25, 2007 the application displays images taken from a fleet of specially adapted cars. Areas not accessible by car are sometimes covered by Google tricycles. On each of these vehicles there are nine directional cameras for 360° views at a height of about 2.5 meters, GPS units for positioning and three laser range scanners for the measuring of up to 50 meters 180° in the front of the vehicle. There are also 3G/GSM/Wi-Fi antennas for scanning 3G/GSM and Wi-Fi hotspots.

2. No about the fighting issue that i have reffered in the subject topic.Now whether it is a facility for the world base users to utilize viewing live views of streets world vide or it is an attempt to log in to the private data of the users across.....yess...I repeat it is the private data of the users avaiable from the open WiFi signals from their home computers and laptops.The intresting thing is that Google has accepted this collection of data from unencrypted wireless networks....and they have put the blame on a masoom software engineer.Google says the massive furore over Wifi snooping by Street View cars was all the fault of one software engineer.In an interview ,CEO Eric Schmidt said the whole affair came about because a software engineer inserted unauthorised code into the Street View system software. The man is now under investigation internally by the company as per posts on google blog.

3. Now what ever answer that google may come up with in form a mistake or simply putting the blame on that software engineer(...where was the Software Testing deptt and QC then otherwise?),the point that I intend putting accross is that just take care of envryting your WiFi router.Google has at least accepted the fact and mistake and they are taking measures to rectify it...but it will not be always like that.....there are so many mis adventurists present all around that looking around that unencrypted wireless networks for misuse.....just read this post again to avoid becoming a target like others.

Mobiles & Brain Cancer : WHO Speaks.

1. In an earlier post at,wherein the sad and bad effects of using mobiles on brain and health,the quantified SAR ie specific absorption rate were discussed.There is good news for those who always feared using mobile phones for standing at a risk to gain brain cancer in the long run.The WHO study on links between mobile phone use and certain types of brain cancer has proved inconclusive.The researchers said that even though there could be possible health risks from heavy mobile phone use, nothing conclusive has been found as yet.

2. The long ten year study of about 13,000 people focused on both healthy users of mobile phones and those with two types of brain cancer - glioma and miningioma tumors. There were suggestions of an increased risk of glioma, and much less so meningioma, in the users with highest decile (10 per cent) of cumulative call time, in subjects who reported phone use on the same side of the head as their tumor. Strangely though, the study declares these 10 per cent to be people who use their phone to call for more than 30 minutes a day. These stats seem seriously doubtable. Going by it, almost everyone we know is in that 10 percent.

3. However, the study has been criticized, as biased, because mobile phone companies provided 25 percent of the it is more then 15 years when the world has been actively using mobiles...more so in india in last 10 years....had it been the other much of the human populi in the world would have been effected by now....

Google and Caffeine : The Secret Link

1. A little over year ago ,Google unveiled a “secret project” of “next-generation architecture for Google’s web search“ which was supposed to include crawling, indexing, and ranking changes. While the biggest visible changes in Microsoft’s relaunched search engine, Bing, was user-interface related, Google’s secret project was supposed to be only infrastructure related and proposed no UI changes.

2. Thus after an year of the unveiling,Google is now getting faster and more comprehensive with a new Web indexing system called "Caffeine.As per the Google Blog Post's , the project now stands on completion stage and now "provides 50 percent fresher results for Web searches".

3. The old indexing architecture was based on several layers, some of which were refreshed at a faster rate than others; the main layer would get updated every couple of weeks.To refresh a layer of the old index, entire web was analysed, which meant there was a significant delay between when we found a page and made it available to the user. With Caffeine, the web is analysed in small portions and search index is updated on a continuous basis.Thus more improvement on existing setup....that I say "there is no end to improvement"

Prisoners all set to est BPO : A first from Cherlapally Central Jail

1. In a country where media,politicians,government, bureaucrats,actors,sportsman etc etc and most of the citizens are busy baking power and minting money,this is one news that could do HINDUSTAN proud.

2. In a bold & really unique experiment,likely to be the first of its kind in our country,there will soon be BPO units with the inmates as employees. This is a unique development and Cherlapally Central Jail in Hyderabad@Andhra Pradesh is the first prison throughout the country to have such a unique facility in its premises.These BPO units will have educated convicts serving out their terms. A public-private partnership was signed up between the prison authorities and the Bengaluru based IT firm, Radiant Infosystems.As many as 250 inmates will be enrolled in the BPO unit and they will be later shortlisted according to their qualifications. Most of the inmates are matriculates and graduates. The shortlisted inmates will then be given training by experts and then absorbed by the BPO company into their Jail unit. For starters, the convicts working there will not have any access to phones as in the case of a normal call centre. They will be mostly involved in bank-related data entry and transfer work.

3. "We found that large number of convicts are willing to work on computers. So, I thought these prisoners can made use of and they can be put on computer-based jobs," said Gopinath Reddy, Director General For Prisons, Andhra Pradesh.

4. This is really positive contribution I feel....although a percent of readers may tend to opine about QoS etc...but...worth a start and Idea....

XINGYUN : World's Fastest Computer

1. "Experts say one second of its work may take a whole day for a dual-core personal computer"

2. Such is the astonishing ..or I say beyond imagination power of this officially disclosed SUPERCOMPUTER named "Xingyun" from China that runs at more than one quadrillion (one thousand million million) calculations per second.

3. XINGYUN is now the server of ‘Dawn 6000’ which has been jointly developed by Dawning Information Industry Co. Ltd, Chinese Academy of Sciences Calculation Institution and the South China Supercomputing Centre. It has been developed for DNA sequencing and for cloud computing.

4. Perhaps there is no end to improvement.....tomorrow will come up with much much higher speeds then XINGYUN......wait and watch.....
