RI offers its solutions in an all-inclusive approach that is shown on the chart:

Service delivery phases

Site, tower, and network audits

Audits are comprehensive analyses of technical and economic parameters of existing cellular networks, helping to understand the current situation and allowing to assess options for future business development. RI collects technical and financial data from an operator with details on base stations, towers, masts, limitations on wind speed, and payload capacity.

The collected data is analysed to find trends, evaluate key performance indicators, develop cost models, evaluate current business plans, benchmark against best practices or competition, and to select locations for possible upgrades. RI offers site capacity studies to determine a strategy for gradual upgrades to reach optimum trunking efficiency levels. The studies include appraisal of measures to reduce the number of required TRXs by 50% or more for given QoS and traffic levels. RI performs site power consumption studies and appraisal of measures to reduce power consumption 10–40 times per square kilometre in comparison to traditional sites.

Demonstration of business cases

Based on site and network audits, business development cases are created with forecasts of future carried capacity per site, total network traffic, ARPU and MoU levels, customer density, site trunking efficiency, cost of different site configurations, and other network parameters. In preparing an opportunity report, RI relies on coverage predictions with Okumura-Hata models for different terrain types and frequency bands, coverage and capacity planning for a possible field trial, and sketches details of future commercial deployment. Frequency planning involves channel assignment, inter-sector interference, carrier-to-interference and carrier-to-adjacent studies, electromagnetic compatibility studies, diversity, and radio link budget analysis.

Seminars and workshops

In parallel with site and network audits, RI offers seminars, presentations, and workshops on coverage predictions and capacity planning with Super Antenna Systems for top management and technical specialists of operators. Such training is necessary in order to achieve deep and complete understanding of the advantages of the Super Antenna Systems concept. On request, RI offers seminars on the topics of specific interest for operators, helping to solve most of the issues through dialogue and open discussion in the earliest phase.

Some of the topics covered by seminars and workshops include the following:

  • Presentation of the opportunity report with results of site and network audits, benchmarking, review of different market forecasts, simulations of alternative coverage and traffic scenarios.
  • Demonstration of strategic importance of continuous reduction of CAPEX and OPEX levels per square kilometre of networks with fast improvements in coverage, QoS, and data rates.
  • Q&A sessions on feasibility of 70–90% lower CAPEX and OPEX per square kilometre, on the Super Antenna Systems concept, RI's “50 Golden Rules”, effects on KPIs and profitability.
  • Discussion of key technical parameters of Super Antenna Systems: antenna gain, EIRP, the Robin Hood effect, input power, traffic capacity, frequency re-use, aperture efficiency, etc.
  • Discussion of radio access network coverage plans for specific territories, including current and future coverage/capacity needs and requirements (e.g. license-stipulated conditions).
  • Benchmarking of Super Antenna Systems against existing sites; comparison with newest and future base station designs from system houses and standard antenna manufacturers.
  • Review and training in the concept of multi-operator, multi-band, and multi-modulation (MMM) Super Site Hotels that enable up to 10 wireless services per site and new business models.
  • Discussion of current EIRP regulations for cellular antennas and possible limitations on antenna radiated power; ICNIRP rules and radiation reduction in the near zone.

Hardware field trials of SAS™

As the next step, RI can offer a pilot project to show coverage and capacity improvements provided by Super Antenna Systems. This step involves detailed specifications for selected antenna and site configurations and placement of purchase orders for towers, antennas, and feeder systems. Civil and installation works are planned and budgeted for at this stage.

During a pilot project, all relevant KPIs are measured through drive tests, including voice quality, call drops, signal level, data transfer rates, and usability of different mobile services. Results are compared with predictions and are used for drafting an updated business plan.

Development of business plan B

With decades of experience in planning cellular businesses, RI can provide business plan B development services to help operators deploy Super Antenna Systems in the most efficient way. After setting new technical and business goals, RI can review existing business plans, adapt business models to lower ARPU levels, optimize sites for more coverage and traffic capacity, and outline key details of a full-scale implementation proposal.

Commercial full-scale roll-out

RI offers project management services and can act as a general contractor for commercial full-scale roll-out. In this role, RI would coordinate production of antennas, towers, and other high-performance RF equipment. Relying on the SAS Consortium, RI can assist operators in sourcing all special SAS hardware components from qualified and experienced suppliers.

Monitoring and optimization

After initial commercial deployment of Super Antenna Systems, RI can offer operational and financial optimizations. Through continuous monitoring, analysis, and fine-tuning of coverage and capacity, RI and its partners can detect trends and offer further network modifications.
