Zinwave deployed four-carrier DAS solution for underground space
The National September 11 Memorial Museum, which serves as the United States? principal institution for examining the events of the 9/11 terrorist attack, used DAS equipment deployed by Zinwave to enable cellular coverage within the museum space.
The memorial ?is located underground, within and surrounded by remnants of the original World Trade Center site. The museum features multimedia displays, archives, narratives and a collection of 11,000 monumental and authentic artifacts.
?Much of the 9/11 Museum is located below ground, so it was recognized that providing cellular service within the museum would be impossible without deploying a wireless distribution system within the museum space. With an estimated 3 million visitors annually, providing cellular service to museum visitors and employees was a critical need. The solution had to support multiple frequencies and multiple wireless operators, while seamlessly accommodating future growth,? the company said.
To solve this challenging scenario, Zinwave installed its UNItivity solution which supports any frequency from 150MHz ? 2700MHz.
?System implementation was quick and easy. Small, unobtrusive remote units were placed throughout the museum to achieve comprehensive cellular coverage of the space, and linked back to centrally-located hubs using flexible fiber cabling.?
Zinwave highlighted that the system immediately delivered cellular service for the four major operators: AT&T, Verizon, Sprint and T-Mobile. Initially supporting 4 commonly-used cellular frequencies? 700MHz, 850MHz, 1900MHz and 2100MHz?the solution was designed such that adding additional frequencies will not require any costly infrastructure upgrades.
?Zinwave DAS solution can support all cellular and public safety frequencies between 150MHz to 2700MHz. Even if you initially deploy a DAS solution supporting the signal of only one wireless carrier, adding additional carriers and additional frequencies will not require new hardware.?
Zinwave?s in-building wireless solution uses fiber cabling throughout the system. The fiber cabling serves as the system?s backbone, running end-to-end from the hub out to the remote units. The fiber infrastructure makes the system not only more affordable, but also easier to install, the company explained.
