Case Study - Reduced DAS Costs w/ Macro Reduction

Introduction: RF networks have evolved from tower-top and roof-top macro sites to a combination of macro, iDAS/oDAS (indoor/outdoor Distributed Antenna Systems), small cell and hetnets. The prime motivation for this network evolution is for the improvement in network quality demanded by subscribers. The propagation tools used for the initial design of these networks is typically inadequate in modelling and adapting to the evolving networks types deployed.

The Need for SRVCC in VoLTE

The use of Single Radio Voice Call Continuity (SRVCC) in early deployments of VoLTE networks is critical to maintaining the current customer expectations of the voice call experience. As LTE networks often lag earlier technology networks in coverage, software reliability and general network optimization, SRVCC is the vital gateway to transparently maintaining the customer experience. Operators will continue to enhance the LTE networks coverage and reliability to the standard of current legacy networks, however the ability to rely on the 3G/2G voice networks for backup is critical.

RF Shaping - Cell Footprint Optimization

RF fundamentals for wireless networks begin with proper cell footprint. A cells coverage needs to meet the desired coverage objective and only the objective. RF Shaping is critical to short term performance gains, maximum parameter optimization, and getting the most from costly and limited wireless spectrum. RF Shaping can best be summed into three reasons:

  1. Maximizing Coverage
  2. Minimizing Interference
  3. Long Term Savings $$

Small Cell Optimization Considerations

Indoor small cells are typically installed in venues to fill in small coverage holes to provide better voice quality, data throughput speeds and reduced drop calls at a very low Installation cost compared to a conventional DAS system. As with any other wireless system small cells have to be carefully designed, installed and optimized to provide optimum coverage and quality to end users.

KEY DESIGN CONSIDERATIONS TO ACHIEVE AN OPTIMIZED SMALL CELLS NETWORK

DAS Optimization Considerations

DAS systems are an effective way of adding coverage and capacity and have become an integral part of a wireless network to provide an effective solution in challenging RF environment. DAS solution deployed in various environments requires Optimization of the network in order to meet network performance requirements and excellent customer experience.
