Mobile broadband traffic is growing exponentially as people connect to their contacts, applications and services on their mobile phones. By 2020, mobile networks need to be ready to deliver one gigabyte per user per day, downloaded at speeds more than ten times the current levels.

This the biggest challenge for mobile operators offering broadband services.

Any new capacity added to the network should consider intense and considerable investments
In cellular networks the maximization of data capacity can only be achieved with the aquisition of more spectrum bandwidth, with further cell splitting and spectrum reusability (i.e. more base stations) both combined with modern Radio Access Technologies (RAT's) that can offer significantly higher spectrum efficiency.

Our products respond to this exact need of the mobile telecommunication industry. We offer the latest antenna and radio site infrastructure technology available in the market. Aiming to improve the data capacity performance of your network, SONAR can help you generate a highly profitable revenue, reduce OPEX and keep CAPEX under control while creating a better experience for your customers.

It is widely known that radio planning parameters used by network operators to install base station antennas are based on radio propagation models which simulate radio coverage and capacity. However, although such models can predict coverage in geographical space with relative accuracy, the signal quality (i.e. capacity metric in modern broadband wireless technologies) per user in time cannot be really predicted.  

The coverage and capacity offered from a base station antenna in its dominant geographical space of service is defined by the average signal to noise and interference ratio (SINR) levels encountered by the mobile devices served. Each mobile user establishes a discrete radio link with the base station antenna, but all users are served by the finite amount of radio power available in the 3-dimensional antenna radiation space.
HotspotWhen the majority of users served are located outside the antenna’s main radiation (-3dB horizontal beamwidth), a lack of power (due to low EIRP encountered by these users) result in low average SINR levels recorded in the antenna service area. YES! It is true: Mobile traffic and user distribution in time and place is by default dynamic!!! As such, these underperforming radio links, when served by a power limited radio access technology (RAT), in turn result in poor base station investment for the network operator.

Thus the “fixed” radio planning parameters used by network operators carry inherent inconsistences and errors. During the course of a day or week an uneven mobile traffic and user distribution split in reference to the service base station antenna main bore (clockwise or counterclockwise) significantly impact the base station SINR performance. As a result, we come to the conclusion that the antenna’s azimuth planning parameters need to be dynamically adjustable in order to “follow” the generated traffic in time and place.

Radiation Pattern and User DistributionIn order to achieve this objective (i.e. locate high usage area clockwise or counterclockwise the antenna’s horizontal space), the deployment of an azimuth fine tuning and control optimization system is required to operate the installed mobile radio antennas and its mounting structures. SONAR integrates a smart, adaptive and self-organizing antenna feature set in order to achieve enhanced base station performance through antenna azimuth directionality fine tuning and control.

This dynamic adjustment of antenna radiation towards geo areas of high demand provides the capability to increase by an order of a magnitude either the number of users served (minimizing admission and congestion), the average network speeds (increasing data capacity and throughput) or both. Simply by focusing the finite energy where is needed, SONAR enables the optimization of power utilization.

Throughput verses SINRThis power budget optimization offered will result in better performing base station capacity to at least an average of 20% (just by a 1dB power efficiency) for any power limited RAN technology such as 3G, 4G and future 5G. This power resource saving allows the network's Radio Resource Manager (RRM) to share more power to the radio links, resulting in better overall network KPI's.
