Antenna efficiency is impacting the overall network performance

Boosting connectivity

A novel evaluation method for enhancing antenna efficiency impact on the network

The impact of antenna efficiency on network performance

Antenna performance metrics and parameters significantly impact user experience and network energy efficiency. Advanced network simulations with 3D far-field radiation patterns highlight the critical importance of beam efficiency on overall system performance.

This paper emphasizes the significance of appropriate evaluation methodologies to assess the impact of antenna parameters on network performance metrics. It argues that comparing antennas based on their network impact, rather than datasheets and one-dimensional metrics, leads to more efficient networks. Simulation results in dense urban scenarios show that higher antenna beam efficiency significantly enhances uplink and downlink performance, potentially resulting in 18% and 21% user throughput gains in downlink and uplink for cell-edge users, respectively.

Crucial evaluation methodology

Using the right evaluation methodology is vital for assessing the impact of mechanical and electrical antenna parameters on network performance metrics.

Advanced simulation tools

Ericsson’s sophisticated simulation tools provide the most accurate network performance estimations based on antenna parameters, aiding in the development of top-performing antennas.

Network impact comparison

Comparing antennas based on their network impact, rather than relying mostly on datasheets and one-dimensional metrics, is the best way to select antenna solutions.

Beam efficiency benefits

Higher antenna beam efficiency leads to improved uplink and downlink performance, particularly in dense urban scenarios.

User throughput gains

An 11% improvement in beam efficiency can translate to 18% and 21% user throughput gains in downlink and uplink for cell-edge users, respectively.

A comprehensive strategy for sustainable network evolution

A holistic view of network evolution

As outlined in Ericsson’s RAN Modernization Guide, communication service providers (CSPs) must evolve their networks sustainably. Introducing new services and expanding network capacity as done in the past will increase energy consumption, operational expenditures (OPEX), and carbon emissions. A holistic approach to network evolution is essential to maintain high performance while meeting business and operational targets.

The role of antennas in network evolutions and modernization

Antennas are critical for sustainable network evolution, expansion, and modernization. A strategic approach to antenna selection in network design and modernization offers tangible benefits, including enhanced performance, user experience, energy efficiency, future-proofing, scalability, and reduced total cost of ownership (TCO).

Performance metrics in practice

Antennas are evaluated using mechanical and electrical metrics, including wind load, size, passive intermodulation (PIM) levels, reflection coefficient, and radiation patterns. While these metrics simplify the complex characteristics of antennas, they do not fully capture the three-dimensional nature of antenna radiation, which is crucial for predicting network performance.

Advanced 3D simulation methodology

Ericsson’s advanced simulation tools incorporate full 3D antenna radiation patterns into network-level simulations. This methodology allows for precise analysis of antenna performance in realistic deployment scenarios, providing insights that guide the development of high-performing antenna solutions.

Better network performance

Antennas with higher beam efficiency provide better network performance by improving signal quality and reducing interference.

User throughput gains

Simulation results indicate that antennas with a beam efficiency improvement of 11% can lead to significant user throughput gains.

Developing efficient networks

Accurate simulation methodologies combining antenna system simulation with network-level evaluation are essential for developing efficient wireless communication systems.
