Wireless System Design

The design complexity of simulations and calculations involved in today's wireless systems demands the most advanced design tools as well as a dedicated corps of engineering and business problem-solvers. Outsourcing design development to CelPlan allows you to tap the expertise, efficiencies, and cost-effectiveness that result in significant savings and a successful enterprise.

Getting Started

The system evaluation phase results in a complete business plan, resting on a solid foundation of feasibility studies; estimates of the number of RF channels required per year for different penetration rates; demographic data; quantity and cost of equipment needed; technology recommendations; and return on investment. In this phase, CelPlan's expertise extends across the following typical operations:

• Economic modeling with proprietary CelBusiness software, which evaluates system options with different implementation strategies
  
• Field measurements for evaluation of spectrum cleaning requirements and determination of morphology parameters, using CelTools software
  
• Determination of the availability and costs of sites
  
• Feasibility of PSTN interconnections and transmission systems
  
• Assessment of competitors' performance
  
• Database preparation
  
• Wireless traffic information displayed in a grid format, with traffic intensity attributes per bin, expressed in Erlangs
  
• Cell grid generation in a hexagon pattern
  
• Coverage goals and precise link budget calculations to achieve the required class of service performance
  
• Positioning of sites in accordance with databases and field observations
  
• Frequency plan generation
  
• Preparation of Composite, Best Server Plots, and Cell Site Search Area Maps, using CelPlanner software
  
• Networking to optimize interconnections with CelNet software
  
• Link analysis to ensure proper availability
  
• Spectrum management to minimize relocation and/or spectrum cleaning requirements

From small, stand-alone systems to nationwide networks, CelPlan systems have been deployed worldwide and are currently in successful commercial operation. CelPlan design capabilities encompass all technologies (analog, TDMA, and CDMA), numerous applications (cellular, PCS, trunking, paging), and a range of frequencies (450, 800, 900, 1800, and 1900 MHz).

More than a hundred man-years have gone into the development of the CelPlan design tools. They are buttressed by CelPlan's areas of technological expertise in:

• Switching equipment design and dimensioning
  
• Different transmission technologies (wired cable, optical cable, VHF/UHF, microwave radio, and satellite links)
  
• Cell site/base station equipment design
  
• Propagation theory and modeling
  
• Traffic theory

The combination of CelPlan's wireless design experience and its profound knowledge of the technology options best suited to each case optimizes equipment and manpower planning, modeling, database preparation, and coverage analysis, so that the bulk of problems are foreseen and resolved while still in the design phase. This provides an obvious cost benefit to our customers.

CelPlan's multilingual staff can offer designand consulting services either as an integral, stand-alone team or in concert with the customer's engineers.

CelPlan's unique, state-of-the-art technologies and well-qualified engineers and planners offer a potent combination for any and all phases of wireless deployment. Because our expertise reaches across the planning, equipment, and systems aspects of wireless deployments, CelPlan is in a strong position to create cost-effective, smoothly executed solutions to your wireless system designs.
