  How do wereach there? Broadband through Wireless Mumbai • Population density – 21k/sq.km • But, 34% (approx) wet land • Actual population density ~ 90- 100k/sq.km. in some areas or even more (Source: UDRI) • Assume 10% use broadband services in such areas and 1 Mbps demand per user • Very high capacity required: 10 Gbps/sq km – Assuming 2-3 cells/ sq km, we need about 3-4 Gbps per cell With 100 MHz per cell (multiple operators and multiple technologies) ~ whopping 40 bps/Hz/cell !!!

  Evolution of WirelessSystems 4G IMT-A / LTE-A 2G / 2.5G GSM / CDMA 1x Mbps 10x Kbps 3G WiMax / HSDPA 100x Mbps Downlink Spectral Efficiency (bps/Hz/cell) ??? How do we reach 40 bps/Hz/cell 7 approx. 5-6 approx. 3 Data Rate Wireless Mobile Systems Objective Increase in Spectral Efficiency Solution Small Cells

  Contrasting Challenges Citizens: - Access to broadband - Data requirement with growing demand - Choice and migration across operators Private operators: - Flexibility of planning - Network layout and architecture - Scalability and upgrades Municipal Corporation – Point of Intervention: • Right of way & digging permissions • Ensure availability of resources • Ensure no inconvenience to citizens • Ensure future-proof policies • Zoning Government of India: - Implementation of schemes as per National Telecom Policy Municipal Corporation: - Enable use of citizen services to the masses - Interconnection of municipal facilities - Maintenance of public utilities like roads, flyovers etc.

  Role of MunicipalCorporation in Broadband
• 12.
  Roles of differententities • Private Telecom Operators – Infrastructure setup and management • Government – Spectrum auctions • Any role of Municipal Corporations? – YES!!! • Enabler for private telecom operators • Broadband for citizen services • Municipal public-park approach • Universal Service Obligation Fund?
• 13.
  Enabler for privateoperators • Creation of Telecom Corridors Water Pipelines – Lay trenches, dark fibers & conduits – Identify areas for tower installation (Zoning) – Provide connectivity to tower from trenches – Lease fiber to private telecom operators Municipality laid • Changes in building code fiber ducts/ conduits/ dark Gas Pipelines – Mandate builders fibers to provide ducts for optical Optical fiber during construction Fiber Ducts – Facilitate In Building Solutions (IBS) • Map the details of all underground utilities and make available to all operators

  Broadband for citizenservices • Municipal Broadband – Services overlaid over telecom corridor School Hospital Police Station Fire Stations Municipal Broadband Tower Municipal Telecom Corridor CCTV Cameras

  Municipal public-park approach • WiFi hotspots in public areas in underserved locations

  Case Studies
• 17.
  Case Studies –Stockholm • City owned network • Laid out by municipal corporation • 10,00,000 km of fiber across the city • Rented to operators for a fee • 90% of households connected with fiber to home of which 25% are low household incomes • Operates at a profit of ₹150 crores
• 18.
  Case Study –Lebanon (Oregon) • Public Private Partnership Model • City wide coverage in a partnership with ISPs • Access points provided to educational institutions • Free Wi–Fi available to all for limited time per month • Can be extended for a paid price • Part of subscription money received given back to local civic body
• 19.
  Planning

  Mumbai Ward H/East Includes • Dharavi slum cluster • Dense urban areas in Mahim / Santacruz, Vile Parle • Educational campus of Mumbai University in Kalina • Bordering the airport complex Data • Area: 13.5 sq. km • Population: 5.8 Lakh • Slum Population: 4.5 Lakh (79%) • Number of households: 42.5k per sq.km • Population Density in residential zones: ~200k per sq.km
• 21.
  Mumbai Ward H/East Main Conduits Urban Bandwidth demand • 10k urban households • 5Mbps in 50% households • 25Gbps Slum Bandwidth demand • 34k households • 256kbps in 50% households • 4.5Gbps Towers in 13.5sq km • 2Gbps per sq km • Small cells, 100Mbps per 500m sector • Approx 250 towers Dense Residential Area Educational Areas SMhaorreed tThoawne ro Innefr aosptreurcatutorer Government Services • Access to Schools/Hospitals • Public WiFi / Surveillance
