Becton Dickinson

SQUAN was hired by Becton, Dickinson & Company to augment cellular voice and data coverage at their headquarters in Franklin Lakes, NJ. The site consisted of two large office buildings, each with approximately 400,000 square feet of floor space. The two buildings were connected via enclosed walkways through the Campus Center, a partially subterranean dining facility with small shops and a bank. The campus houses 2,500 full time employees and guests.

Given the site layout, cellular coverage presented challenges. Coverage from the wireless carriers was fair on the highest level, and became poor to unusable on the lower levels and in the Campus Center.

To solve Becton Dickinson’s coverage problems, SQUAN designed an active DAS to provide cellular coverage to the entire facility, including 8 remote amplifiers, 165 antennas, 12,000 feet of coaxial cabling and 2,000 feet of fiber optic cabling. Installation was performed after hours to minimize impact on employees. Cabling was run above drop ceilings, and antennas were installed partially above the ceiling to minimize visual impact and maximize coverage.

The system was designed to support both AT&T and Verizon Wireless. Close coordination with both wireless carriers was maintained throughout to ensure that they would accept and join the DAS.
The Head End was located in the Computer Center, where connections between the DAS and the wireless carrier signal sources will be made.

The DAS system was built and tested over a 6 month period between November 2014 and April 2015. The network was tested for performance over all four frequency bands (700 MHz, Cellular, PCS and AWS) and coverage of -75 dBm over 95% of the facility was achieved. This coverage level will provide reliable, high quality service for AT&T and Verizon.

After completing the DAS build for Becton, Dickinson & Company, SQUAN was hired by both companies to install their equipment and connect to the DAS. AT&T and Verizon are currently preparing to connect to the DAS. It is expected that the DAS will be carrying live traffic from both AT&T and Verizon Wireless by August 2015.
