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.

The objective of this report is to design a parallel 4-bit adder for low power consumption using 0.18 micron technology. The transmission gate implementation of the 4-bit ripple carry adder is chosen. Implementation is based on a bottom-up design methodology from schematic design of individual devices to integration. Critical paths are abstracted and optimized for low power dissipation. The schematic design is translated into prefabrication layout. Simulation of the schematic and layout realizations of the adder is performed and results are discussed. Performance is validated with specifications imposed by the target application.

Flockingducks (http://fducks.com) is a social network which my partner, Yen Pin Hsiao, and I had created. The service keeps track of your contacts (so you don’t have to). With the ever changing nature of our contact list be it phone numbers, emails, and myriad of other networks, the aim of the service is to consolidate all of the bits of information and synchronize your gadgets in the end.

This project was a labour of love. I recall the days when we sat in William’s coffee shop just on the outskirts of campus, penning out our ideas right after we finished our final semester of university. It was a tremendous effort between the both of us in planning and building the website with everything crafted from scratch and which ultimately took about a year (on a part-time basis) from concept to launch. Till this day, the website is still a testament of the slick craftsmanship and of our creativity.

The Singaporean government faces a new challenge to accommodate rising demand for public housing but also strive to retain the nuances from the past. The following architectural study that I wrote shall investigate whether there is a correlation between daily activities held within the premises of a typical apartment complex in relation to morale as found in traditional Kampung ways.

Singapore: A Study of High Rise Living

This is a sculpture that I had created using scrap pieces of wood with white primer. The sculpture is of a lady. It is to be viewed from behind as it gives a sense of mystery to the appearance that is shyly turned away. The selection of wooden blocks, unaltered, required much thought particularly of the shoulder area where a thin bent slab was used to give the otherwise stiff structure a subtle grace.
