Information traffic grows exponentially
• Globally the number of mobile internet users will surpass desktop users by 2015
• Smart phones, social networking, video on demand, video streaming,
e-education, e-books, mobile video conferencing
• BOYD (bring your own device) • Push up information storage & transport

Generations of mobile systems
• 1G, 2G,3G, 4G and LTE (long term evolution)• Digitisation• Computer Switching ( Routers), MPLS ( multi
protocol label switching )• Modems (analogue – 4kbps, 16 kbps)• BB (Broadband), 64 k, 256k, 2MBPS, 8 MBPS,
100MBPS ,(N GBPS)

spectrum even before auction but they required to pay what the auction determined)

Reliance-Mukesh Ambani’s Infotel)
• Invests in 3/5 yrs $8 bln• Constructs 100,000 RKM of O/F cable• Phase-I Towers 7000• Traffic aggregators 3500 ach in Delhi &
Mumbai based on FTT X technology• Pan India BWA already invested $2.8 bln• Subscription @ Rs. 800/1000 pm

Google Fiber Project (to boost Internet speed)
July 2012, Kensas City)• High Speed & internet @ $ 120 pm• 1 GPBS Internet B/W (100 times faster than
current speed)• 2 TB of DVR storage 1 TB of Google Drive• Free Google News 7 Tablet• Reliance Info promises ( 10 to 30) MBPS
THC_CTMS S681 _Dec'12 13
Tower Requirements• India ‘s population density – 150 (Andaman); Delhi -1800
per sq. mile • 1000 subscribers per tower • One tower for 6 sq.miles to 18 towers per sq.mile• MBPS per tower for 2G-40; for 4G-800• India has 4,50,000 towers• Tenancy ratio required :2 to 3 per tower • To reduce radiation to less than 1 wt per sq. mtr we need
at least 25,000 more towers at a cost of Rs. 7,500 cr.• Local bodies and property owners are becoming hungry
wolves and clearances are costing huge monies
14S681 _Dec'12THC_CTMS
Back -haul
• 1.5 to 2 GBPS from each tower• Terrestrial microwave is less expensive than
Optical Fiber systems (digging and resurfacing costs are a source of unearned income for local bodies and highways)
• Both TDM and IP traffic require back-haul • Encapsulation : Ethernet is cheaper than MPLS
which is superior
15S681 _Dec'12THC_CTMS
Broadband wireless access (BWA) (1)
• The spectrum auction in June 2010 netted $ 8.4 bln (Rs. 40,000 Cr) (the 3G netted Rs. 68000 Cr)
• Target for broadband subscribers by 2014 – 100 mln • Only Reliance Infotel has nation wide licence (cost $ 2.74 bln )• Aircel has a spectrum in 8 circles, Airtel and Qualcomm in 4
circles each; BSNL all over India • LTE ready equipment vendors - Nokia Siemens networks,
Huawei, Alcatel Lucent & ZTE• WiMax is also LTE technology and some a re deploying it. • FD, LTE & TDLTE
16S681 _Dec'12THC_CTMS
Broadband wireless access (BWA) (2)
• 132 operators in 56 countries are now investing in LTE • 45 networks are in operation now• Reliance uses LTE-TTD (time division duplex)• Qualcom (which ha s licence in 4 circles) supplies
equipment to every operator promotes TD-LTE in competition with WiMax• Qualcom has multi mode chip sets which enable equal
footing for services in 2G, 3G and BWA • Aircel demonstrated high definition video streaming and
three way video conferencing using inter-operable TD-LTE dongles
• Speed 110 mbps and low latency of 10-20 milli sec .
17S681 _Dec'12THC_CTMS
Monies raised through spectrum auction
• 3G – Rs. 68,000 Cr• Broadband – Rs. 40,000 Cr • Reliance Infotel (Mukhesh group) – 4G Spectrum in June 2010 @ Rs. 4,800 Cr Investment to be made Rs. 27,500 Cr • Content creation : 15% to creator; 15% to aggregator; 70% to
Telcos but Reliance Infotel will pass on 50% to Telcos and aggregator
• Content- video on demand, live video, mobile video conferencing, e-education(bought online tutoring company extra marks education pvt.) , network 18 TV content, triple play ( voice, entertainment and education)
• Technology used: (TDD)- time division duplex- LTE will provide voice service through applications like Skype and
Viber
18S681 _Dec'12THC_CTMS
Auctioning Spectrum is disastrous • Gamblers instinct• First mobile service licences were auctioned• Fantastic “upfront paid “ bids led to near death of Telcos • Telcso migrated to revenues share in 1999• Right thing to do - invite bids for revenue share and not for
spectrum price • DOT/government has stake in Telcos wellbeing • DOT/gov take equity in Telcos to control• Money made is squandered on “Feed and breed” welfare programs • About 30% of what users pay and tax on profits go to government • Telecom R&D, and indigenous manufacturing languishing • Defense, security , infrastructure are starved
19S681 _Dec'12THC_CTMS
Should Spectrum be Priced?• Like air it is an inexhaustible resource , which can be
used again and again all the while Infrared, ultra violet, x-ray…..• Solar power • Sun’s light rays spectrum is not sold• The product that is electricity is sold • Devices convert sunlight to electricity are sold and
taxed . So only products and services derived from spectrum should be sold .
• Take Nitrogen from air and produce fertilizer what do you sell /tax?
20S681 _Dec'12THC_CTMS
Industry Woes (1)
• Telco Revenues @ Rs. 1.5/2 Tln.• Telco Investments of = Rs. 3 Tln• Telcos debt Rs.3 Tln• Debt of Telcos to Banks Rs. 1,00,000cr (R-Com = Rs. 35,000 cr)• Profits are declining• ARPUs lowest in the world• Hyper competition
– Services customers– Sickness for companies
• DOT/TRAI-function?• Raising Revenues for government or • Reaching service upto aam admi• Return on capital employed <6.5%
S681 _Dec'12 21THC_CTMS
Industry Woes (2)
• No company has declared a dividend in the last 18 years
• Share prices’ performance below BSE index • Banks not enthused to finance 2G spectrum
purchases.• A Kotak Investment Study finds need for
“Viability Gap Funding” by government ?
S681 _Dec'12 22THC_CTMS
Perverse views of DOT/TRAI• Asking internet service providers (ISPs) for revenue share.• Asking tower companies to pay revenue share and take a licence • Asking cell companies to pay spectrum charge determined by 2012
2G auctions for the remaining period of the licence of P-telcos 2014/15 . (Electricity transmission towers and distribution poles do not require a licence nor do they pay anything to any body.)
• Withholding VOIP for the last 10 years an d now saying OK• Not allowing 3 G roaming between different company networks
(no single company got 3Glicence for the entire country – Airtel- 13; Idea-11; Vodafone-9; BSNL-everywhere )
• Suggesting reforming of 2 G networks from 800 MHZ to 800/900 MHZ bands
