  1. Policy formulation for telecom towers (cell sites) for Chandigarh Administration Association of Unified Telecom Service Providers of India

  2. Overview of Telecom Services in Chandigarh (Punjab Telecom Circle) • No. of licensed Operators: 8 (7 operators have launched services and 1 operator is to launch in Q4/2004). • Technology used: CDMA (4 operators) & GSM (4 operators) – both are world-class digital technologies for cellular mobile telephone service. • Date of launch of services: 1997 onwards • Subscriber Base (as on 31st August 2004) • Punjab: 30.60 lakhs • Chandigarh: ~ 6.12 lakhs

  3. Overview contd… Allocation of Wireless Spectrum by Govt. of India: • Spectrum (frequency) is a limited finite resource allocated for different wireless applications to different users. • Telecom services is one of these such applications. • Present allocations by GoI for telecom services: • CDMA: 800 MHz band • GSM: 900 & 1800 MHz band • Efficient utilisation of existing allocations calls for increase in cell sites since there is a spectrum constraint.

  4. Cellular Architecture • Cellular architecture by its very nature calls for a contiguous arrangement where signals are transmitted from one site to another like a chain – handoff of signals from one site to the next contiguous site while the subscriber moves. • No voids (blank pockets) can exist as it will result in call disruption or calls will drop due to poor / no signal in the handsets. • Cell radius – typically 350 m. • As the number of users increase and their need for mobile communications results in higher traffic, which calls for increase in no. of cell sites.

  5. Typical Cellular Network – an illustration Initial Stages (1-2 years) Later (3-5 years onwards) Less number of subscribers. Less traffic generated by few subscribers. Cell radius comparatively large. Cell site density less. Subscribers increase rapidly (4-10 times or more). Traffic generated increases substantially. Cell radius reduces in size. Cell site density increases.

  6. Concerns expressed by Authorities • Height of the towers & aesthetics - to blend with the surroundings • Structural safety of towers • Health hazards • Pollution control – air (smoke) and noise • Flying / aviation hazards • Residential Areas

  7. Height & Aesthetics Issue: • Height (25-30 m from ground level) is necessary for clear line of sight for radio waves (signals) to have effective coverage. Industry viewpoint: • Cell-sites to be erected in back lanes (not visible from main roads). • Existing architecture (civil constructions eg. water tanks) to be used. • Micro-cells to be used on street lights, poles, etc. • Building rooftops to have pole mounted antennae / rooftop towers (lesser height) to blend with building exteriors. • Environment friendly architecture on roundabouts can be constructed on which antennae can be mounted. • Camouflaging with appropriate colours to blend with surroundings.

  8. Structural Safety Issue: • Structural stability and safety aspects. Industry Viewpoint: • There is no compromise on structural safety. • Industry meets stringent structural safety standards. • Industry already complying by submitting structural certificates from qualified engineers when site approval is sought.

  9. Health Hazards Issue: • Probable impact on health, heart or on brain of location of towers in residential areas. Industry Viewpoint: • No evidence has been collected internationally to prove that emissions are harmful to human life. • WHO has done extensive research which can be examined on their website to exhibit level that radio waves are not health hazardous.

  10. Pollution Control Issue: • Air and noise pollution effects on environment. Industry Viewpoint: • DG sets used by operators are complying with noise and emission levels as prescribed by CPCB.

  11. Flying / Aviation Hazards Issue: • Cell sites may cause obstruction in flight path near the airport. Industry Viewpoint: • SACFA (GoI Committee) which has membership of IAF and AAI approve each and every cell site location in the country. • SACFA coordinates with field units (airports, IAF bases) before granting approvals to verify these concerns. • No approvals given by IAF & AAI for such cell sites which obstruct flight path, therefore approved sites cause no obstruction.

  12. Residential Areas Issue: • Requirement of cell sites in residential areas. Industry Viewpoint: • No cell sites in residential area would create pockets where there is no service. • Cell sites required for commercial services. • Health, Structural safety and pollution issues - Already being complied with for commercial and institutional areas – not different for residential areas in any manner. • Present ban must be revisited to remove these deficiencies.

  13. Residential Areas (contd…) Why should this be allowed? • RF planning in network design mandates cell sites within residential areas to maintain contiguous nature of cell sites – any void / blank pockets would lead to disruption. • No cell sites would mean poor Quality of Service – call drops, voice breakages, no signal for in-building coverage. • Situation leads to a violation of license conditions which mandate 90% in-building coverage to measure rollout obligations. • VVIP residential area - Ministers / Politicians, Bureaucrats, business community - the hub of decision-makers cannot use their mobile phones. High degree of complaints on service providers for no service.

  14. Sharing Infrastructure • Operators on an average share 15% of their total sites with each other. • All operators continuously explore possibilities of sharing of cell sites. Why all cell sites cannot be shared? • RF Planning varies between operator to operator - location, height and distance of cell sites is variant between each operator – is dependent on subscriber base and traffic in the network. • Radio interference problems leading to poor QoS / no service. • Structural safety norms allow only two operators to share a single site.

  15. Conclusion Industry Expectations: • Simple, transparent and easy to implement procedure for installation of cell sites and consequent growth of mobile services. • Quick and time bound approvals so that network expansion is not hindered. • Cell site installations in Residential areas to be allowed.
