50 Energy opex saving strategies for Telecom operators

My friend (and regular contributor at this blog) Pareekh Jain has just sent me an interesting post with fifty opex saving strategies related to green telecom. Please find it below. Enjoy it!

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


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


6. Passive Infrastructure Sharing – Tower Sharing, Power 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


10. Replacing Shelters with Cabinets

11. Green Shelters – PUF Panels


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


20. High Efficiency Rectifier

21. Sleeping Functionality in Rectifier for Low Loads


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


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
