A majority of currently deployed base stations only achieve efficiency levels of around 20 to 30% while best-in-class base stations still only operate at 45% efficiency levels. The remainder of the power is wasted as heat. In comparison, ETAdvanced currently achieves over 70% efficiency bringing a number of advantages to mobile infrastructure vendors and operators:
Power consumption is a very significant cost for mobile operators representing 18 to 50% of total OPEX. ETAdvanced brings a 50% power saving to macro base stations with a direct impact on operator profitability.
ETAdvanceddramatically reduces the power consumption of all base stations. This makes it possible to power small cells (e.g. pico and femto cells) with the Ethernet cable alone, greatly simplifying the power supply solution required.
Lower power consumption means less need for fuel for backup power. This provides supply chain advantages in developing countries with transportation and security concerns for diesel used to power backup generators.
Since ETAdvanced reduces the cooling needs of base stations, the overall cabinets can be made significantly smaller. This reduces rooftop real estate rental costs and makes it easier to obtain ideal locations from a network planning perspective. This creates both cost savings and improved customer experience as a result of improved indoor coverage.
ETAdvanced makes it possible to replace mechanical fans with natural cooling. As a consequence, there are fewer moving parts in the base station cabinets that can break down. This reduces the rate of mechanical failures and the need to dispatch maintenance teams to repair faulty cooling equipment.
The low power consumption means that base stations in developing countries can be fully solar powered using on-site photovoltaic cells.
