Systems

 

 

Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

Last month, I wrote about how fiber was being used to expand bandwidth for cellular systems, connecting cell towers to the phone network and antennas on the tower to the base electronics. That helps our phone coverage when we’re driving or walking outside.

Workflow-management tools are designed to orchestrate everyday business processes. For example, a contractor may implement a process for submitting, reviewing and approving expense reports.

While the electric power industry rapidly changes, utilities and building owners will need to accurately model the engineering and economic operations of the power system to make informed decisions, so they require sophisticated modeling-software tools.


Power is everything. Consumers demand connectivity to home, business, people and places 24 hours a day. In this uber-integrated information society, staying in touch through Wi-Fi, Ethernet, cellular and other networks is the expectation.
