It has been estimated that 80% of cellular phone calls begin or end inside a building. DAS lets building owners add value for their tenants and their employees by enabling the use of mobile devices throughout the building. A DAS can support multiple carriers and even improve the battery life of phones.
The need for bandwidth to facilitate data transfer has skyrocketed. DAS ensures reliable data transfer rates and coverage by bringing carrier signals directly into buildings.
Cellular technology is constantly changing and DAS Simplified helps building owners and contractors grow and adapt with those changes.
What is DAS?
Mobile devices are redefining the way we work, play, and live. Technology has brought devices and applications that improve our productivity and our mobility. However, mobile service quality can be compromised indoors. That’s because RF (radio frequency) signals have difficulty penetrating thick walls, metal structures, and energy-saving windows. In addition, new building codes often mandate a public-safety wireless system for first responders like fire department and police. The traditional approach has been to build two separate systems, but now building owners have the option of one combined DAS (distributed antenna system) that powers both public safety and commercial cell networks, leveraging shared infrastructure and lowering overall cost.
Blocked radio reception is a particular problem for first responders, who depend on unobstructed communication to ensure the safety of themselves and others in emergency situations. The events of 9/11 highlighted the need for reliable radio coverage in large buildings. To date, at least 30 states have adopted or will soon adopt codes that apply to first responder coverage.
With the enactment of IFC 510 in 2009, the fire code was updated with suggested jurisdictional guidelines regarding emergency responder radio coverage. The following are a few important IFC 510 suggested requirements.
Public Safety / First Responder
All new buildings should have approved radio coverage for emergency responders within the building.
Radio signal strength requirements must be met in 95% of all areas on each floor of the building.
All existing buildings should have radio coverage throughout the building and are required to retrofit the building with radio coverage if the existing wired system is not able to be repaired or is being replaced; or per a timeline as identified by the jurisdiction.
Aside from these guidelines, specific codes are set by State, County, and City requirements. It can be difficult to understand what is truly required by your jurisdiction. Contact Raceway Technology to find out more about codes in your area.
All Raceway Technology designs meet or exceed current jurisdictional standards and can be designed to meet anticipated future codes and regulations.
