NEBENS offers design services and works with customers on a contract basis.  An initial meeting is held to discuss the
customer's problem and the goals of the contract.  A project proposal is then created by NEBENS and submitted to the
customer.  Upon agreement on the proposal, its goals, timeframe and pricing, NEBENS undertakes the project through
a contract.   We are experts in the approach of coupling the propagation environment with Multiple Input Multiple Output
(MIMO) antenna systems and, as a strategy, partial to undertaking projects in this area.  Typical design services include:

  • Antenna design for wireless products
    • Single antenna systems (multiband, tunable, etc. designs)
    • MIMO antenna systems (antenna architectures, design and algorithms)

  • RF planning
    • System Analysis (Frequency Reuse, SINR and Throughput Analysis)
    • Ray Tracing
    • Antenna design for specific propagation environments

  • Cognitive Radio, Interference Mitigation and Dynamic Spectrum Access
