Airrays Gmbh & Amphenol Antenna Solutions Active Antenna

4/5/2017

Amboise (France), April 2017 – Airrays GmbH and Amphenol Antenna Solutions (AAS) have successfully presented their active antenna at MWC in Barcelona. This solution is a tangible technological step forward in the perspective of the migration to 5G. It embeds advanced digital beamforming and FD-MIMO schemes for optimum capacity gain. Its CPRI interface to the baseband unit enables easy integration in existing RAN infrastructure and can also be interfaced with gateway to the IP network. Last but not least, the Total Cost of Ownership of this solution is superior to any kind of capacity solution like small cell or macrocell layers.


Airrays GmbH and Amphenol Antenna Solutions have partnered to developed a Large Scale Antenna (LSA) product. From an architectural standpoint, the objective has been to use a modular structure and distributed power amplifiers (PA). Indeed, with LSA, each transmitter can have a lower output power and a higher antenna gain. The dipoles are fed by small PAs providing the right adjusted power level to each element. The number of modules and their arrangement can be adapted to the horizontal and vertical beam scanning requirements. Thus, the key advantages of the LSA are: multiple cells can be projected from one site, arrays of multiple sizes can be created thanks to its modularity and large uptilt and downtilt ranges can be achieved for building coverage (from the outdoor). The LSA is a flexible solution for capacity overlay in dense cellular network environment.


The active antenna offers CPRI connectivity to the baseband unit, for easy operation with any OEM. Trials can easily be engaged with any OEM for interoperability. Moreover, field trials with Carriers are underway in order to evaluate the solution in real conditions, especially to evaluate the capacity add-on.


Maximum attention has been paid to the Total Cost of Ownership of this solution. The solution has a small footprint and offers propagation conditions that leads to minimum site acquisition efforts by reducing the number of sites. The selection of the architecture and its small PAs contributes to more cost effectiveness while controlling the power consumption. So less site acquisition constraints versus traditional small cell capacity layers, better cell dimensioning versus macro or small cells, LSA is a new generation of solution for network design and return on investment.


The LSA roadmap already includes several frequency bands, in TDD or FDD mode. We anticipate to increase the number of independent beams, among other features evolution for capacity. We anticipate to offer several options for the interface to the baseband unit also. And more to come.


Finally, the Airrays GmbH and AAS active antenna solution is an ideal bridge from 4G to 5G, offering much more capacity in various form factors and various applications. It is also easy to integrate in existing cellular networks.
