Telecommunications

Experience in all levels of networking from physical to transport. Experience in both RF and visible light communications.

Introduction

Designing a part of or a full communication system is a rigorous process that includes: 1) a good understanding of communication technology concepts which enables suitable breakdown of the required functionality; 2) research and evaluation of cutting edge and industry standard concepts to select the best technology for implementation at each stage of the system; 3) proposing a clear and cost-effective architecture of the overall design including proper component selection; 4) hardware and software implementation of each design unit; 5) capability to verify final design and functionality.
