Energy efficient antennas – Antenna testing to Elisa Oyj

The wireless performance of an antenna affects its energy-efficiency and this way to its sustainability. Verkotan has performed OTA antenna pattern measurements to the first Nordic carbon neutral operator, Elisa. Read more to find out how is antenna testing related to environmental sustainability.

Energy efficient antennas – Antenna testing to Elisa Oyj

Sustainability is an ever-rising issue worldwide. It affects every company in every industry and telecommunication industry is no exception. You might ask, what does antenna testing has to do with sustainability? By testing your antenna’s performance, it is possible to determine if the antenna is as functional as it was designed to be and therefore energy efficient. Antenna testing eases the selection of an optimal antenna for a specific environment; when optimal antenna is selected, network operates more efficiently, and base stations and user equipment use less power. Sustainability of an antenna is dependent on a following things:

  • Antenna design – wisely designed antenna maximises its efficiency. For example, the placement of different component affects the energy consumption.
  • Antenna material – material choices such as plastic, metal etc. affect the sustainability of an antenna. Material choices also affect the energy consumption. In addition, when antenna is built from quality materials, its lifetime longer.
  • Antenna efficiency – Antenna efficiency means the amount how much energy antenna radiates compared to the amount of energy supplied to it. For example, if antenna at its best could radiate 100W, in real life it might radiate only 60W. In this case antenna is not efficient and uses more energy.
  • Antenna pattern quality and MIMO quality. Antenna pattern affects the sustainability because different antenna patterns are suitable for different environments. If antenna pattern is not good for a certain environment, it will consume more energy. MIMO quality is important, since it affects how much bits can be transferred per watt.
  • Cable loss – cable loss means the loss of power due to cable’s length.

Sustainability and Elisa 

Sustainability is in Elisa Oyj’s core values. One of their many achievements is that they were the first Nordic operator to become carbon neutral. Verkotan was happy to provide Elisa Oyj with antenna testing to verify the high-quality performance of their base station network and the energy-efficiency of the antennas they use. This provides a longer service life for the antenna and better performance for the end user, which is a top priority for Elisa. 

The efficiency and antenna patterns of Elisa Oyj’s 5G FR1 base station antennas were evaluated and measured in our near field to far field (NF-FF) laboratory with our unique NF-FF transformation. The near-field characteristics are converted to far-field characteristics using software and necessary transformation algorithms. The NF-FF approach considerably reduces the required distance to get the required far-field characteristics of an antenna and this testing enables Elisa to optimize the antenna’s service radius to its full potential. 

We did multiple antenna measurements for Elisa, for them to be able to select the best antennas for their network and provide the best possible internet and cellular service for their clients. When antenna measurements for multiple antennas are performed in the same laboratory, the test results are more accurate. This is because the testing conditions will remain the same and the only dependant variable will be the antenna performance.
