LINKPlanner Developer. LINKPlanner is a disruptive, powerful sales tool that allows sales engineers to connect two points wirelessly, create and optimize networks, and then create a bill of materials.Composed requirements to incorporate licensed microwave and unlicensed microwave, Point-To-Point (PTP) and Point-To-Multi-Point (PTMP), low-cost and carrier grade products into LINKPlanner. • Assembled system requirements from diverse product teams and analyzed applicability, consistency, and fidelity before creating LINKPlanner requirements. • Wrote formal Technical Requirements Document (TRD) for PTP 820E, Cambium Networks’ first 80 GHz PTP product. The TRD provided rationale for cable and product selections. • Raised numerous LINKPlanner requirements Jiras—Using Jiras instead of TRDs for minor product changes saved review and implementation time.Tested LINKPlanner implementations against requirements—identified and debugged problems before LINKPlanner was released.Created and presented LINKPlanner webinars to end customers, distributors, and value-added resellers.Answered customer questions via public community forum web pages. Public community forum allowed questions to be answered once in public, instead of many times in private.Co-developed and delivered train the trainer LINKPlanner training for Cambium Networks Certified Trainers. This training reduced the total time LINKPlanner developers spent teaching LINKPlanner.
