s. Such projects are deemed higher risk, as they are often for new infrastructure, new customers, and even new owners.

, a greenfield project could be that of rolling out a new generation of cell phone networks. The first cellular telephone networks were built primarily on tall existing tower structures or on high ground in an effort to cover as much territory as possible in as little time as possible and with a minimum number of
base stations Base station (or base radio station) is – according to the International Telecommunication Union's (ITU) Radio Regulations (RR) – a "land station in the land mobile service." The term is used in the context of mobile telephony, wireless com ...
.{{Citation needed, date=June 2013 These early wireless telephone network designs were later augmented with additional base stations and antennas to handle the growing demand for additional voice traffic and higher network capacity. As wireless networks quickly evolved, it was evident that the earlier designs constrained the growth of the network. As governments made more

available for licensed wireless telephone operators in the late 1980s, entirely new networks were built that performed better than legacy networks because their designs were free from the constraints of existing systems.

are also referred to as greenfield projects.


Other uses

Literal examples of greenfield projects are new factories, power plants, airports which are built from scratch on greenfield land. Those facilities which are modified/upgraded are called
brownfield land In urban planning, brownfield land is any previously developed land that is not currently in use. It may be potentially contaminated, but this is not required for the area to be considered brownfield. The term is also used to describe land prev ...
projects (often the pre-existing site/facilities are contaminated/polluted.) In transportation industries (e.g., automotive, aircraft, engines) the equivalent concept is called "clean sheet design". Greenfield also has meaning in sales. A greenfield opportunity refers to a marketplace that is completely untapped and free for the taking. From an Information Technology Service Management (ITSM) perspective, an IT organization that is being set up from scratch is said to start from a "greenfield" situation. This is because it would have no live services or practices in place to start with.
