Indian Mobile : Sustained Stupendous GrowthNDIA- ICRIER RESEARCH FINDINGS

Ø  Telecommunications is a critical building block for the country’s economic development.

 

Ø  Access to communications needs to be seen as a foundation on which other initiatives can be built.

 

Ø  In under served areas, mobile phones can help to widen markets, create better information flows, lower transaction costs and substitute for costly physical transport

 

Ø  Small and medium sized enterprises (SMEs) and urban slums gain maximum benefits in enhancing their businesses through the use of mobile services.

Amidst the spreading gloom of the economic downturn following the global financial meltdown, the Indian telecom sector provides the proverbial silver lining…………….”Dr. Rajiv Kumar, Director, ICRIER

Information via mobile, such as weather reports and market prices, has begun to have an impact on productivity for the agricultural sector.

 

Ø  Real benefits of telecommunications only start when a region passes a threshold penetration rate of about 25%. Many areas have still not attained that level, which indicates the importance of increasing teledensity as soon as possible.

Ø  Indian states with higher mobile penetration can be expected to grow faster, and by 1.2% points for every 10% increase in mobile penetration rate.

These benefits are from 2G, with 3G – expected to increase several fold

 

3G in INDIA

v In India fixed line broadband connectivity is very low;

          Quite likely that many people will probably first use and experience broadband on their mobile handsets

          3G will bring in the much needed broadband connectivity for both rural as well as urban India

 

In India, when You think Broadband,

Think Mobile Broadband

MOBILE BROADBAND FOR INDIA

Ø         To build an integrated eco-system of service providers, content providers, application providers, etc.

Ø         Integrate India & the Indian consumer with the far reaching developments that are taking place across the world.

Ø         Bring the much needed foreign investments into the country.

Ø         Extremely effective tool in driving penetration of the huge addressable market in the rural areas.

Ø         Increased economic opportunity through tele-education, tele-medicine, e-governance, etc.

Ø         Facilitate achievement of Government’s broadband objectives

RACE FOR WIRELESS BROADBAND

3G Spectrum2.1 GHz:

v          1920-1980 MHz

v          2110-2170 MHz

2.5-2.69 GHz:

v          2500-2570 MHz

v          2620-2690 MHz

 

Recently, WRC-07 identified the following frequency bands for IMT applications:

v          450-470 MHz

v          698-806 MHz

v          2.3-2.4 GHz

v          3.4-3.6 GHz

2.5 – 2.69 GHz BAND

v          Government guidelines for providing BWA services, states that-

          Spectrum to be Auctioned in 2.5, 2.3 GHz bands.

          Each successful bidder to get 20 MHz in 2.3 & 2.5 GHz bands.

v          Highlights of TRAI recommendations, dated 11th July 2008 –

          Identified 2.3,2.5 & 3.3-3.4 GHz bands for BWA services.

          A maximum of 15 MHz in both these bands.

          Recommended 2.3-2.4 GHz for TDD mode.

          Recommended 40 MHz (available) in 2.5-2.69 GHz for TDD, if Department of Space does not vacate.

v          Present Status in India

 

COAI VIEW:

2.5 – 2.69 BAND BE RESERVED FOR 3G

v          In India, entire band of 2.1GHz not fully available for 3G services

          Hence, adequate availability of 2.5 – 2.69 GHz band for extension of 3G is a must

v          Technology neutrality approach should be followed

          Spectrum should be allocated to both FDD & TDD

l           Advantage of minimum risk of interference

l           Offers economies of scale

 

v          India should follow Option 1 of ITU which permits both FDD & TDD

 

 

USE OF 2.5 –2.69 GHz FOR 3G IS

VITAL FOR GROWTH OF BROADBAND

                BEYOND 3G

HSPA (HIGH SPEED PACKET ACCESS)

v          HSPA is the set of technologies standardized by 3GPP3 that defines the migration path for UMTS operators worldwide. HSPA includes HSDPA (High Speed Downlink Packet Access), HSUPA (High Speed Uplink Packet Access) and HSPA Evolved . 

v          As of date, 1,470 devices are available:

Ø         624 mobile phones and UMPCs

Ø         155 PC data cards (PCMCIA cards, Express Cards, chipsets, embedded modules)

Ø         323 notebooks

Ø         197 USB modems

Ø         136 Wireless routers/gateways

Ø         19 Femtocells

Ø         10 Personal Media Players (PMPs)

Ø         6 cameras

v          Backward Compatibility

          With Existing 3G/UMTS

          Consistent with 3GPP standards.

v          Delivering peak rates of 14Mbps in the downlink and 5.8Mbps in the uplink today.

v          Ever-improving performance, with commercially-proven transmission bit-rates of up to 14Mbps today and up to 42Mbps in the near future.

v          Highly economic urban and rural coverage, with up to 200km cell range and measured speeds in excess of 2Mbps at the cell border

 

LONG TERM EVALUATION

v          LTE is an all IP network based upon TCP/IP, with higher level services such as voice, video & messaging, built on top.

v          LTE has considerable flexibility, supporting channel bandwidths from 1.4 MHz to 20 MHz.

- This optimises the use of radio spectrum by making use of new spectrum and refarmed spectrum opportunities.

v          Operators evolving to LTE from GSM/WCDMA/HSPA will maintain full backward compatibility with legacy networks.

v          LTE will have scalable channel bandwidths using OFDMA with both TDD and FDD operation.

 

LTE BENIFITS

v          All IP nature of LTE means converged services will become a reality

v          It can deliver the massive capacity at a much reduced cost per bit.

v          Applications like High Definition (HD) video streaming, mobile gaming will be possible with LTE.

v          Low latency (below 10 ms) & higher Data throughputs.

Global LTE ecosystem is being developed by a global group of

21 LTE equipment vendors & 8 operators, who are planning phased

interoperability tests to ensure the availability of a wide range of

LTE devices

Global LTE ecosystem is being developed by a global group of

21 LTE equipment vendors & 8 operators, who are planning phased

interoperability tests to ensure the availability of a wide range of

LTE devicesØ   700 MHz (698-806 MHz) band best suited for HSPA/ LTE applications.

Ø         This band especially relevant for India, as majority of future growth expected from rural India.

Ø         Because of its excellent signal propagation characteristics, less infrastructure is required to provide wider coverage

– Communication services can be provided in rural areas at lower cost( savings in capex)

– Will help to bridge the ‘digital divide’ in India

– Provide affordable mobile broadband to help develop a knowledge based economy.

 

STATUS OF 700 MHz BAND

UHF Band IV

v          There are 14 TV channels available in the UHF Band-IV (470 -582 MHz) with 8 MHz channel bandwidth.

v          Doordarshan is operating about 330 transmitters in this band.

v          Doordarshan’s three digital TV transmitters at Kolkata, Chennai and Mumbai are also operating on an experimental basis in this band.

v          Recently Doordarshan has started its Mobile TV service in Delhi (using DVB-H technology) in this band at channel 26 on experimental basis.

UHF Band V

v          In this frequency band, there are 28 channels available with 8 MHz bandwidth in the sub-band from 582 to 806 MHz.

v          Doordarshan has not been assigned any channel in this sub-band for analogue TV transmission.

v          However, frequency earmarking has been made in favor of Doordarshan to operate Digital Transmitters in four Metros.

v          In UHF band V, Defence and BSNL are operating point to point microwave links in 610 – 806 MHz,

v          PPDR has some spots earmarked in 746 – 806 MHz

v          The UHF Band V above 806 MHz has been extensively assigned to cellular mobile services etc.

COAI’S VIEW

v          In line with the WRC-07 outcomes, COAI had suggested the following band segmentation to be incorporated in the revised NFAP: 

v585-698 MHz be earmarked for Mobile TV  /

Digital Broadcasting

v698–806 MHz be earmarked for IMT applications

Thus, there is a need to allocate 100 MHz of digital dividend band to mobile services

BAND PLAN FOR 700 MHZ BAND

Ø         700 MHz band should be reserved for FDD to improve overall spectral efficiency & allow deployment of LTE by multiple operators.

Ø         Most efficient solution is a 2 X 50 MHz arrangement (with 8 MHz gap)

This plan has several advantages, as listed below:

Ø         will minimize risk of unfavorable fragmentation of the band for mobile broadband usages, thereby reducing complexity of terminals.

Ø         utilizes largest amount of available spectrum hence most spectrally efficient.

Ø         Provides reversed duplex transmission arrangement, i.e., higher frequency band for uplink for better co-existence with adjacent radio communication (broadcast) services.

DIGITAL DIVIDEND BAND FOR MOBILE BROADBAND

Ø         Because of its excellent signal propagation characteristics, less infrastructure is required to provide wider coverage

– Communication services can be provided in rural areas at lower cost( savings in capex)

– Will help to bridge the ‘digital divide’ in India

– Provide affordable mobile broadband to help develop a knowledge based economy.

 

Ø         Other countries vigorously actioning this project, e.g., US has vacated 100 MHz, UK planning to vacate 128MHz

 

Ø         India can easily make 100 MHz (698-806 MHz) available for mobile industry.

 – Sufficient spectrum available for broadcasters in lower bands, hence, need of both, the mobile industry & broadcasters would be fulfilled.

India needs to take a lead position in allocating this band to drive economies of scale
