Why 4g LTE at 700 MHZ

Should Government Auction 700 MHz For LTE Rollout?

In order to make broadband access more affordable and to have better pan India coverage, Government of India is planning for auction of 700 MHz band for LTE at the end of the financial year 2012.

This will be possible once Prasar Bharati completes digitization for Doordarshan and Air and Defence forces and vacate spectrum in 700 Mhz band following the roll out of optic fibre cable (OFC) made by BSNL.
In this article, I will discuss the advantages & disadvantages of 700 MHz band for LTE roll out. My views on expected socio economic benefits and opinions of all Telecos, who would like to participate in this auction.

6 Reasons Why 700 MHz Band Is In Hot Demand For Mobile Communication?

1.    The UHF frequency band from 470 MHz to 862 MHz, often referred to as the 700 MHz band, has lower propagation losses than the 2500 MHz or 3500 MHz bands.

2.    700 MHz spectrum is a more efficient spectrum than 2.3 GHz and hence would require lower capex/opex to cover a similar footprint.

3.    It has better in-building penetration and lower Doppler shift

4.    The ecosystem on 700 MHz FD-LTE is much more mature than 2.3 GHz TD-LTE

5.    It requires less complicated equipment. It would require less power to run a mobile phone/Internet cell on the 700 MHz band than on the other common bands, which are at higher frequencies.

6.    Infotel Broadband Services said as the duration of the spectrum holding is of 20 years, the reduced Capex has a multiplier effect. In addition, the reduced base stations would mean reduced Opex. Therefore, the economic value of the spectrum in 700MHz band is not only higher than 2100MHz band, but is also higher than the 900/800MHz band.

Thus, LTE on 700 Mhz band can revolutionize growth of internet in India.




5 challenges with 700 MHz band

1.    Dealing with 700 MHz antennas is a much greater challenge than 2.4 GHz antennas (and even more than 900 MHz antennas) because 700 MHz antennas are physically much bigger (and therefore heavier and harder to mount on towers and buildings and thus expensive).

2.    It's also a challenge to "constrain" 700 MHz system's coverage to only the geographic area that your license covers; that calls for careful, expensive system design at the edge of your coverage area.

3.    It has lower spectral efficiency. Therefore this extremely valuable spectrum resource needs to be used in the most efficient way to allow for mass usage where it is needed the most.

4.    It's looking like we could face a situation where different service provider providing 4G services in different bands, which ruin the handset compatibility amongst the operators. Because 4g works on various frequency bands like 700 MHz, 1500 MHz, 2300 MHz along with various modulation technology.

5.      Operator might adopt restrictive device practices on carrier‐specific band plans designed after the 700 MHz auction. Handsets should be interoperable.

Not everything is good with  4g Network

1.    4g Roaming is not completely tested technology.

2.    In my opinion, the two biggest hurdles that will be faced in delivering on the promise of 4G are managing channel quality and individual user throughput expectations. Here are critical challenges of 4g  .

Opinions of various Telcos for the auction of 700 MHz band

Largest private telco, Bharti Airtel (got BWA license in just 4 circles) is lobbying for auction of this band. It has stated openly that its 4G strategy will rest mainly on future allocations in 700MHz and FDD 2.5GHz along with experimenting with these four circles.

It is expected that Tata Tele, Vodafone, Idea Cellular (aims to be a pan India ISP) and Telenor/Uninor (who did not take part in 3G auction), Sistema/MTS (given they prioritize data services) along with Mukesh Amabani controlled Infotel is expected to participate it.

How operators are using multiple frequency bands in LTE roll out?

4G network can work at 700 MHz, 1500 Mhz and 2300 MHz band.  But, worldwide operators prefer to use higher band like 2.3GHz band, LTE deployment in urban areas where data demand is high and 700 MHz is for rural connectivity.
1.5 GHz has a problem because it interferes with GPS frequency.

Is the auction good for Indian economy?
In 2008, the US government raised close to $20 billion by auctioning three blocks of spectrum in the 700 MHz band.

Indian government got a whopping 106336 crore rupees ($22.7 billion) from the sale of airwaves (3G and 4G combined). Of this 67,715 crore rupees( $14.48 billion) is from 3G auction and 38,570 crores($8.25 billion) is from the sale of broadband wireless or 4G airwaves.

Finance ministry planned to raise Rs 40,000 crore or more through the auction of telecom spectrum in 20012-13 (FY13). There are going to be deep pockets bidding for 700 MHz, most purely as a speculative investment without having to build out actual communication systems. This is good for the Government to manage fiscal deficit of budget.

Is Auction best way?
I personally do not think auction is a good way to give away spectrum. It would be better that the Government give away spectrum to eligible companies at a cost which ensures affordable data & voice services to end users.

Take the example of 3G, operator bought at a huge cost, they are in debt and after 2 years of roll out 3G is yet to take off. If Government likes to earn money from spectrum, it would be a wise decision to insist on annual revenue sharing model with the operators.

This will ensure better quality and coverage. This will enable the Government to spend money in a much more planned way and there will be less chances of new scams to arise.

This should leave enough money on the table for the operators to use 4G to enable the bigger change, which is essentially around bridging the digital divide in India and making sure that there is higher broadband penetration.

All of that said, this year's 700 MHz auctions are going to be very interesting to observe. There are many, many factions (some who have yet to "uncloak") that will be competing for 700 MHz spectrum.

Benefit to common man from the auction

The significant socio-economic benefit are that millions of people will get low-cost mobile services essential for their needs, with internet connectivity, especially in rural areas and the much needed access to educational, financial and health services.
Positive economic impact driving job creation, innovation, productivity, egovernance, telemedicine, e-agriculture competitiveness; a 10% increase in broadband penetration delivers 0.1-1.4% GDP increase.

The impact India will have includes a 21 percent rise in rural internet subscriptions; or an additional 14 million rural internet household by 2020, apart from a cumulative $68 billion rise in GDP till 2020.
The report also expects about 0.2 percent and 0.4 percent additional uplift in manufacturing and service firms’ productivity due to greater rural adoption and about $15 billion incremental tax revenues to government. It also expects creation of 327,000 new jobs.



Who will be the possible gainer of 4G auction?

RIL will benefit the most, as it has an all-4G strategy and definitely more cash than the other players. It has a more advantageous position than the other players and since other players have already invested in 3G also.

With cash flow from other businesses, Infotel may change the broadband scenario forever with the cheapest entry point.

If NTP 2011 guidelines allow opening up of the IP telephony in India, one of the biggest beneficiaries will be Reliance Industries' LTE business. At present, LTE technologies enable service providers to offer data. LTE with data and voice will become a compelling combination for bandwidth hungry customers in India.

Future of Augmented Reality - A Report

Is Augmented Reality a disruptive technologies ? 

Telecom blogger Mr. Pradeep Chakraborty mentioned in his award winning blog that

 • The increasing focus on incorporating augmented reality (AR) elements within mobile applications will lead to nearly 1.4 billion annual downloads of such apps worldwide by 2015, up from just over 11 million last year.
Video on Augmented Reality & Motion Capture Shopping App

 



 • Annual revenues generated by mobile AR applications and services are expected to approach $1.5 billion by 2015, up from less than $2 million in 2010.

 • Enterprise apps with AR elements are expected to account for the third-largest proportion of revenues by 2015, after location-based search and games. High-profile companies such as Carlsberg are integrating branded AR apps into wider campaigns, while others – Time Out, Royal Mail, Coca Cola - are using B2C applications such as junaio to facilitate AR content. These initiatives are indicative of a growing desire amongst brands to use AR as a key tool to engage with the consumer.


In this report I will be evaluating how AR will help consumers and why it’s simply not a disruption but a real thing.

Let me first explain what is android augmented reality?

 Augmented Reality is the process where computer generated graphics is added to real life photos to provide additional information to the user. AR and its comparison with virtual reality are best explained in this video. Android augmented reality is nothing but AR working on Amdroid phones.

   

 From a pure technology standpoint, AR requires object recognition and computerization on the mobile device itself, as well as 3D rendering to superimpose images on the real world. With there always on connections and high quality cameras the current generations of smart phones provide a natural home for Augmented Reality, and it’s now possible to create your own AR scenes with the Aurasma App on the iPhone.

Here is an excellent article describing how to create augmented reality using Aurasma App on the iPhone.

Best augmented reality app based on my personal experience

 9 iPhone & Android Apps that will make you feel like you're in the future through augmented reality. 

In my last few trips to aboard to attend affiliate summit or conference, I got opportunity to experience following apps which make me feel that I’m actually in future or in a country of science fiction. I’m really fan of these 9 iPhone & Android apps. Actually some of these apps are also changing the landscape for online marketing.

Augmented Car Finder, Spyglass , Golfscape GPS Rangefinder, ZipReality Real Estate, Metro AR Pro ,Google Goggles, Layar, Yelp. Personally I like ios augmented reality over augmented reality on android.


How to Create Your Own Augmented Reality? 

Here are three of the companies behind several recent promotions: Ogmento, Metaio, Total Immersion. You can contact them to create special promo for your marketing initiative. Here are some application of AR in real life It is also reported in PCworld  that Google will come with its own google glasses. The glasses will have a built-in low-resolution camera that will look at what the wearer is seeing and then overlay information about nearby buildings and friends -- a bit like the glasses in the Terminator movies.

A new total immersion augmented apps demoed at the Texas Instruments booth this year at this year’s Mobile World Congress which can assist retail apparel purchases from internet.

How AR is going to benefit telecos as well as well as content provider in India? 

Here is a vast scope for entrepreneur to build AR based application for promotion of real estates, educations, location finder and tourism industry. There are popular games like batman augmented reality, Augmented Reality Gaming on PS Vita.

Every year thousands of people are coming to India. Just imagine the volume of possible business for an AR based tourism guide with authentic information.

Layar, backed by Intel Capital, has seen its software downloaded to more than 10 million devices. I can guess an AR apps on Indian tourism will easily have 1 million download in a year if it’s prices at the range of $2 to $5.

There is also possibility to add location based ad as an extra revenue option. AR goggles developed by Oytun Akman at the Delft University of Technology in the Netherlands,make crime scene investigation a desk job . These types of 3D application can be localized for India and can be used to stop ant subversive activities or counter terrorism.

There are several augmented reality sdk kits are available for developing these types of AR application. Some Angel investors consider AR as a possible disruptive technology and might be ready to invest because there is no doubt about its market.

How smartphones can have everlasting battery?

The idea of an everlasting battery for mobile phones and laptops is mind-boggling.

Actually, some serious researches are going on using Piezoelectric materials.  These materials  has a property of  transforming ambient vibrations into electrical energy that can then be stored and used to power other devices. In the first video you will see the mechanism of generation of Piezoelectricity & in next video, you will see an interview with Dr. Madu who is currently working with this technology. This technology will be available by 2015 commercially as per Dr. Madu.

In this video, you will find how simple to generate Piezoelectricity.



Three types of piezoelectric devices tested are the commonly used monolithic piezoceramic material lead–zirconate–titanate (PZT), the bimorph Quick Pack (QP) actuator, and the macro-fiber composite (MFC).

This could be a solution for recharging of batteries of smartphones soon in an environment friendly way.

A team of researchers at the Royal Melbourne Institute of Technology (RMIT) have measured the energy generated by this film accurately for the first time. And as a result have reached the conclusion that it’s feasible that piezoelectrics could power laptops by using the constant pressure of the user typing on the keyboard.

Dr Madhu Bhaskaran from RMIT University in Melbourne explains her team's research into the creation of an ever-lasting battery.



Boonsri Dickinson mentioned in her article smartplanet.com how this technology has also been used in London club to light its dance floor.

In this article, Boonsri mentioned Georgia Tech researchers have figured out how to make this material generate electricity and perform a calculation at the same time. The study was published in Nano Letters, Advanced Materials. The researcher put zinc oxide onto nanowires because zinc oxide is a good semiconductor. That way, when the material moves, it produces a current when put under mechanical stress.

About Boonsri:

Boonsri Dickinson is a freelance journalist based in San Francisco. She has written for Discover, The Huffington Post, Forbes, Nature Biotech, Technewsdaily.com, Techstartups.com and AOL. She's currently a reporter for Business Insider. She holds degrees from the University of Florida and the University of Colorado at Boulder.

9 Must Have Features For Future Smart Phones

Smartphone is definitely one of the top electronic Gadgets that have changed the world. UBS analyst John Hodulik believe people want high resolution, high speed and smartphones are providing the same to consumer. 


People store private and personal information on their smartphones, and use the devices for e-mails, social networking, banking and payments, consumption and creation of information, content, entertainment and media, navigation, taking pictures, and of course, talking and texting.

I did a study on what’s in the future for smartphones to find how smart phones will look like after 5 years and what amazing things will they be able to do?


Top 9 features of future smart phones

1.    According to Ramon Llamas, a senior research analyst at IDC Mobile Devices Technology and Trends, smartphones will stay around the 3.7-inch to 4.3-inch display size.

2.    Near field communication, or NFC, allows you to make simplified transactions, data exchanges, and connections by touching your phone to an object or another phone. Google has big plans to make NFC even more useful in its next major Android update, known as Ice Cream Sandwich. One of Google's goals with the Ice Cream Sandwich update is to enable what it calls "0-click interaction," which will let you set up peer-to-peer connections via NFC simply by putting two phones back to back.

3.    Augmented reality is another feature we've seen on a few apps here and there, but IDC's Llamas predicts that augment reality will become a standard, everyday feature in the phones of tomorrow. Augmented Reality, is another feature we already see in apps like Layar and Google Goggles, but is likely to be significantly improved. The best augmented reality will quickly recognize the visual input from a phone’s camera and quickly provide information about what you see, such as the direction of the nearest restroom.  The info is based on GPS information, ie: knowing exactly where you are.

4.    Smart phones going to have faster and faster chips.Smartphones will have the processing power of laptops. In June, 2010, DoCoMo started offering the Toshiba T-01A in Japan, a super-fast phone that uses an advanced Qualcomm chip. By 2011, there will be 1.5 Ghz quad core Tegra 3 chips for smartphones and tablets By 2013, there will Nvidia Maxwell chips.Nvidia shared its Tegra roadmap, indicating that its quad-core chips will be at least 50 times faster  by 2014.faster chips and faster download means more download data. This is already a challenge to Telcos and they are stopping unlimited data plan by introducing data throttling. To use smartphones at its full potentials mobile Telcos need to change business process and strategies.

5.    Flexible, thin Amoled Display will be another key contributor.  There will be various technologies and options for large displays that can be rolled up.HP and Arizona state university have Demonstrated flexible displays that can be rolled up This should be on the market in 2012 and in mass production in 2013.  Samsung already confirmed that latest by 2013  Samsung smartphones will have flexible displays.Displays should be also be damage resistance to the scratches, drops, and bumps of everyday use

Here is an excellent video on Paper computer shows flexible future for smartphones and tablets . 





6.    Google Wallet, which was launched recently in New York and San Francisco. In effect Google Wallet will be an app on your smartphone which replaces the need for you to carry cash, checks, or cards of all variety (debit, credit, and store). You’ll link your card to Google Wallet and then use your smartphone as means of payment using NFC (Near Field Communication). Already being trialled in two large U.S. cities, Google Wallet could, if the search giant has its way, be everywhere. Smartphones are replacing the need for a host of other gadgets and becoming a necessity rather than a luxury with each passing month.

7.    Smartphones with built in picoprojectors exist now. Smartphone SH-06C has a DLP projector brightness of 9 lumens and a resolution of 640 × 360 pixels, and is equipped with a 3.7-inch touch screen resolution of 480 × 854.

MIT Technology Review reports that researchers in Germany have developed the world's thinnest "pico" video projector. The device is just six millimeters thick, but it produces images that are 10 times brighter than would normally be possible with such a small device. The new lens system is small enough to be incorporated into a slim smart phone.

8.    Easy Recharging

Battery life is a major concern for smartphone users. Duracell joined forces with U.S.-Israeli company Powermat Ltd. Their joint venture, Duracell Powermat, is producing ultra-thin recharging mats. Duracell plans to equip public places as well as cars, homes and offices with the special surfaces, allowing mobile phones to charge wirelessly by simply placing them on the wired mat. They want to be everywhere in five years.

Smart phones users can expect energy-efficiency to be the greatest screen advancement. Screens are generally what suck a smart phone battery dry, and future screens may incorporate new technologies to reduce energy consumption and promote battery life. You can read my article on latest discovery which can enable to smart phones to have ever lasting battery by 2015.

9.    Eco friendly smart phones with 100% Recyclable housing , Eco-Friendly accessories, Certified Carbon Neutral smartphone & Zero use of hazardous chemical substances .


By 2013, more people will access the web through their smartphones than their computers, and by 2020, mobile phones will be the primary Internet devices for most people in the world. In the future, smartphones will always be connected to the web, through ubiquitous wireless networks (Wi-Fi, Wi-Max and to a lesser extent, through 4G cellular network).

Future Of Mobile Internet Marketing and Advertisement In India

Why The Mobile Internet Marketing and Advertisement Will Be The Key Revenue Earner For Network Providers in 2015?

The fragile economy has created more savvy customers. People are increasingly using mobile internet in-store to research products and prices before purchasing.  According to research conducted by On Device Research , in India 59 percent of mobile Internet users don’t even  use the desktop Internet.

In this post, I will discuss more impact of high speed mobile network on mobile advertisement and why I think this will be key to future revenue stream. 

According to consumer research by The MMA and Lightspeed Research (October 2010), in UK, France and Germany, 45 percent of consumers (especially younger people) noticed mobile advertising and of these, 29 percent responded to it. Of those that responded to the ads, in Germany 49 percent, UK 47 percent and in France 22 percent went on to make a purchase.

This ‘mobile-only’ generation is the segment of the Internet audience who only, or primarily, use the mobile Internet and NOT the desktop Internet.  This new generation can now download and purchase content via mobile, and do not have the alternative of downloading on PC, making it a very significant target group for music and games companies. Actually, people spend more time on their mobile devices than desktops

Currently, in emerging markets including India most respondents use feature phones. For example, in a recent study in Africa, it is reported that only 15 percent of respondents used a smartphone and most of these were Nokia Symbian devices. In developed markets, the devices lean towards smartphones.  Even, companies like Oracle is investing money to provide a Java based solution to feature phone so that people can enjoy several features of smartphone.

 image source -Ronnie05's Blog

The mobile evolution has been advancing at a break-neck pace and mobile is increasingly going to be regarded as an integrated piece of a digital marketing strategy.

Impact of Smartphone & tablets penetration rate to mobile advertisement

Smartphone adoption accelerated in both the U.S. and Europe. U.S. smartphone adoption reached 27 percent of mobile subscribers in December 2010, an increase of 10 percentage points from the previous year, while European adoption reached 31 percent, also up nearly 10 points versus year ago.
Adobe’s Digital Marketing Insights report looked at data from 16.5 billion visits across more than 150 retailers to find that the average order value when shopping on a tablet was $123, compared with $102 on a desktop.

A Marin Software study found that consumers are more likely to click on search results ads when using smartphones or tablets than when using a desktop or laptop. Actual click-through rates in Q4 2011 measured 1.25% for smartphones, 1.31% for tablets and 0.95% for desktops and laptops. Performics reported that mobile click-through rates were 45% higher than desktop through the end of 2011 and January 2012.

By 2015, more U.S. Internet users will access the web through mobile devices than through PCs. And sales of smartphones continue to exceed all other types of computing devices combined, including tablets. Canalys reported that 488 million smartphones were shipped worldwide in 2011, compared with 415 million “total client PCs,” including 63 million tablets. Finally, tablet ownership in the U.S. nearly doubled this past holiday season (mid-December to early January).

Let’s discuss the impact of this new ‘mobile-only’ generation on mobile advertising and marketing

Gartner prediction on mobile ad revenue

2011    $3.3 billion
2015    $20.6 billion

Top 3 Revenue earners

1.    Search ads and location ads (paid-for positioning on maps and augmented reality apps)

2.    Video & audio ads will see the fastest growth through 2015.

Prediction for next three years

• Brand spending on mobile advertising will grow from 0.5 percent of the total advertising budget in 2010 to over 4 percent in 2015.

• Asia will continue to dominate global mobile ad spend, but to a lessening degree from 49.2 percent of mobile ad revenue in 2011 to 33.6 percent in 2015.
Top 3 effective mobile advertisements

• The most effective form of ads was opt-in SMS in the UK (40 percent said they were more likely to respond to these) and in France (21 percent); while in Germany it was mobile Web ads (27 percent).

• Time sensitive special offers or discounts (especially m-coupons) were most likely to lead to purchase.

• People were most likely to purchase mobile content such as applications, music and games.

Here is a survey report by US consumer Mobile Movement on consumer behavior

• Of people who react to seeing a mobile ad: 42 percent click on the mobile ad; 35 percent visit the advertiser’s site; 32 percent search for more information on their phone; 49 percent make a purchase and 27 percent call the business.

• 71 percent of smartphone users that see TV, press or online ad, do a mobile search for more information.

• But 79 percent of large online advertisers still do not have a mobile optimized site, according to Google/Kelsey 2010.

5 Reasons Why I believe 4g will really a game changer for mobile advertisement and marketing in India?

Mobile and wireless network technologies are now the main channels of communication for hundreds and millions of users worldwide. 4G will have a profound impact on entire wireless landscape. 4G offers a highly focused solution to the problems of multiple heterogeneous networks.  Mobile web adoption is happening eight times faster than traditional web adoption in the late ’90s. Mobile searchers have a sense of urgency not seen as often in traditional search methods and they are more focused.


1.    Better Network Quality and advanced services like

2.    High speed & more responsive mobile Web experiences

3.    Data Roaming , multimedia streaming, audio, video and mobile apps.

4.    Cost  Efficient plan

5.    Near Field Communication, a technology already integrated in some high end mobile devices such as the Nexus S, is expected to go mainstream in the near future. Imagine a world in which you hold your mobile device near an ad in a magazine, and the ad then becomes interactive on your device’s display. Such a campaign would once again generate more clicks due to its interactive nature. NFC will change the mobile advertising world as we know it.



In summary, I believe cell phone advertising in india will be a key revenue earner for Indian telecom companies. The strong eco-system that is beginning to take shape with Telcos, OEMs, ODMs, Developers and Consumers will further drive compelling content that will drive data traffic.

China's mobile ad network Madhouse enters India  to tap the mobile ad market of India. See the video on the plan of Madhouse.

Data Throttling - A Conflict of Interest

Bharti Airtel, the world's fifth largest telecom company and India's largest by subscribers, selected Nokia Siemens Networks to build and operate its LTE network (4g) in Maharashtra circle. It has planned to launch this fourth-generation mobile broadband services in India this year.

Reliance Industry will start its PAN India 4g operation in next 18 to 24 months.

The main business case for the 3g and 4G network roll out was enabling subscriber to get high speed data access along with video streaming etc.

In real life scenario, all Telcos also put data throttling which prohibits customer to use data beyond certain limit. To the extent, heard that RCOM is planning to throttle data even for its prepaid subscriber using PCRF. This is a pure conflict of interest.

Consider the people who frequently stream youtube videos or play online games on their mobile devices. These are taxing activities on networks, and not everybody does them regularly. Carriers could potentially create separate types of data plans for customers with specific types of use patterns. They could charge extra for these special plans, and in exchange give these customers priority in gaining access to the higher network speeds so they would get a consistently good connection when playing games or watching video.

Carriers should install deep packet inspection to understand and monitor the types of traffic on their network that are coming from customers. Certain data packets can be identified as gaming-related or video-related, without revealing which specific game or video is loaded on a device so as to respect privacy. If the carrier detects a high amount of video- or game-related activity, it can inform the customers of an option to sign up for a special data plan that suits their patterns of use. I don't understand why operators don't see it as a revenue opportunity. Operator should allow online charging for these types of customers instead of restricting them.

The rest of the customers on normal data plans would still be able to enjoy fast Internet speeds, stream the occasional video or play a game, and not be throttled either.

I believe along with data throttling, deep packet inspection, operator should invest in technologies like dynamic charging for data usage also.

Here is an interesting video on att data throttling  & data usage



I think problem with data throttling is that it has a connotation of punishment. People surpass a certain data level, and then they are slowed down. This is bad.

If these types of restriction will continue, this will bad for subscribers and I don't find any justification to use 4g network. I hope Mr. Mittal and Mr. Mukesh Ambani will help us to use 4g network at its full potential without these types of throttling of speed.

What do you think?

Latest update as per USA today :  

AT&T changes throttling policy for heavy data users on 2nd March'12.

Customer with "unlimited" data plans will face data throttling once they reach 3 gigabytes within a billing cycle.  LTE customer would experience a slowdown at 5 GB of data usage.
