...Maybe Not.
As we work for more energy efficiency, new buildings are being built "green" by meeting LEED standards. LEED stands for Leadership in Energy and Environmental Design and was developed by the U.S. Green Building Council (USGBC) to set a benchmark for design, construction, and operation of high-performance green buildings.
Improved insulation, UV coatings on new windows, and foil backed materials can block or weaken cell signals. This could mean loss of calls and data access. These materials can also affect Wi-Fi deployment. There are ways to mitigate these issues with the use of repeaters, signal boosters, multimode phones, or working with the carrier to add coverage, all of which will have a cost. Another option is to work with architects and contractors who understand this problem and take it into account during design.
Cell phones are a critical tool for business so the next time you are planning to build (home or office), looking at rental space, or walking into a building, think about the need for cell phone communication.
