The greenfield project for wireless infrastructure is the creation of a new network on previously undeveloped space. In an unprecedented project of Vancouver, the goal was to plan, design, build, and commission an entirely new wireless network in a short time frame. Key project managers, engineers, acquisition, and construction specialists were assembled in realizing this ambitious goal.
I was one of the prime RF design engineers responsible for a large geographical area of Vancouver. I looked after RF planning and detailed design of the radio access layer. This entailed high level network design of site placement and cellular configuration to low level on-field surveys of construction sites. With reference to the link budget, the nominal site placement plan was established and zone search activity took place. I conducted site visits with site acquisition and construction specialists in determining suitable candidates that would best meet the nominal design. Deviation of nominal design would encounter a process of review that would conclude with client concurrence.
Upon identifying the site candidate, I proposed a site-level detailed RF design based on propagation, interference, and best-server simulations and compared against KPIs for specified clutter and zone boundaries. Construction drawings were generated of which I reviewed and RF qualified. Detailed build RF design was later specified after further optimization simulations. Parameters related to RNC definition of the cells were also determined such as NCELL and scrambling code definitions. The sites were eventually built and checked on-field for proper RF equipment configuration. To date, the target sites have been constructed to RF specifications.
