Operation temperature range
Working environment analysis for BTS equipment
wireless equipment: Operating temperature: 5℃~55℃,Allowed Max working temperature: 50℃
Transmission equipment: Operating temperature: 0℃~45℃,normally work between 30℃~60℃
Power Supply:SMPS operating temperature -5℃~40℃A/C equipment: Max allowed operating temperature: higher than 50℃
Battery: Suggested working temperature 25℃,every 10℃increasing in operating temperature will cause battery life reduce 50%

Notes: 1. Cooling cost in traditional site in a year = 15kWh/D * 365D * 0.21USD/kWh = USD11502. Cooling cost in HTB site in a year = 0.05 kW *24h/D * 365D * 0.21USD/kWh = USD1003. Supposing both HTB battery and the normal battery can be used at above scenarios for 3 years respectively.4. Air Conditioning shall be replaced every 3 years5. Supposing the maintenance fee and other charges are the same in these two types of sites. 6. Commercial power is 0.21USD/kWh.
Summary: By using HTB battery instead of normal battery in Span site, totally operator will save OpEx – USD3150 for 3 years’ operation.

Notes: 1. Diesel cost in traditional site in a year = (Rs41/L X 2.1L/h X 18 h/day X365 days ) / (55Rs/USD) = USD102852. Diesel cost in HTB site in a year = (Rs41/L X 2.2L/h X 8h/day X 365 days) / (55Rs/USD) =USD47903. Supposing both HTB battery and the normal battery can be used at above scenarios for 3 years respectively.4. Air Conditioning shall be replaced every 2 years5. Supposing the maintenance fee and other charges are the same in these two types of sites. Actually, the Air
conditioner will consumed less power when set up to 35deg.C in HTB Mode.
Summary: By using HTB battery instead of normal battery in Indian site, totally operator will save OpEx – USD16485 for 3 years’ operation.
