Energy is one of the largest opex head for Telecom Operators. Telecom Operators are looking for energy opex savings strategies both for increasing profitability and going Green. Equipment Vendors are looking at opex saving strategies from piece meal perspective limited by breadth of their solutions portfolio. Below is a representative list of some of the Opex Saving Strategies and Possibilities for Telecom Operators.

Planning
1. Reduce Number of BTS ( Decrease Cell Sites , Increase subscribers per site)
2. Reduce Energy Consumption per Site
3. More spectrum .Less BTS
4. Electricity Low Tariff Usage
5. Claim – Carbon Credits

Sharing
6. Passive Infrastructure Sharing – Tower Sharing, Power Sharing, Genset Sharing
7. Active Sharing – RAN Sharing, RNC Physically Shared but logically separated
8. Backhaul Sharing – Infra Sharing
9. Agreement to Switch one network off in low load scenario

Shelters
10. Replacing Shelters with Cabinets
11. Green Shelters – PUF Panels

Cooling
12. Replacing Air Con with Free Cooling, HEX , TEC
13. Intelligent Remote Air Con Control (Temperature, Humidity, Clock Time)
14. No AirCon Requirement on Base Station
15. Compressor Less Air Cooling – AirCon
16. Precision Air Con (PAC)
17. HFC Free Cooling System
18. Inverter based Air Con
19. Passive Cooling Method- Phase Change Material for Storing Thermal Energy

Rectifiers
20. High Efficiency Rectifier
21. Sleeping Functionality in Rectifier for Low Loads

Batteries
22. Increase Battery Life – High Temperature Battery , High Cyclic Battery
23. Battery – Remote Discharge Test
24. New Battery Technologies, – Flow Battery, Ni Cd Batteries, Tubular Gel Batteries

Fuel Management and Gensets
25. Diesel Genset – Remote Fuel Measurement and Management
26. DC Power Genset
27. Genset Remote Management – DG Delay Start Feature

Monitoring and Control
28. Remote Passive Infrastructure and Environment Monitoring
29. Remote Theft Control
30. Measuring Power

Renewable Energy
31. Solar Power with Remote Panel Cleaning, Solar Cooling for Data Centres
32. Wind Power – Vertical Axis, Horizontal Axis
33. Bio Mass, Bio Fuel
34. Fuel Cell – Hydrogen, Methane
35. Genset Battery Hybrid Solution
36. Geo Thermal Cabinets
37. Pico Hydro

Base Station
38. Base Station – Increase in Power Efficiency of RF Power Amplifiers, Base Band Processing Circuits
39. Auto TRX Shutdown
40. Sleeping functionality Base Station – Low Load, User mobility scenarios
41. Use of Micro Sites Along with Macro Sites
42. Strategic Use of Repeaters and Relays
43. FemtoCell – Home Base Station
44. Use Low Powered Micro BTS, Micro GSM
45. Use Human Sensors – Body to Body Network

Core Networks
46. Core Network – Sleep Mode Technologies, Proxy Server Techniques
47. IP Based Core Network
48. Energy Efficient Routers – IP/ MPLS

Backhaul
49. Adaptive Ethernet Transmission rate switching depending on traffic load
50. Mobile Backhaul – Ethernet interfaces- optimized hub/switch site solution
51. PMP Microwave Outdoor

Network Architecture
52. Energy Efficient Deployment Architecture ( MIMO, HARQ, Beam Forming, Wireless Mesh Network, Distributed DSLAM)
53. Voice Compression Technologies – More MON
54. Local Call Intracell – Mobile Media Gateway

Infrastructure Optimization
55. Infra Optimization Solutions ( Separate Battery Cooling, Telecom Towers as Wind Towers, Shelter Roofs as Solar Panels)
56. Remote Radio Units closer to antenna. Lower losses thru feeder cables
57. Tower Mounted Antennas
