Karl Griffith, an author who retired from Gray bar after 39 years of service, wrote an interesting article on Cable Installation & Maintenance entitled as, “Improving Wireless Coverage in Smaller Buildings.” The main subject of the article is about the financial restrictions and allegations that prevent the installation of distributed antenna systems (DAS) into their buildings. Cell phone service providers open up funding large building with Active DAS because of the increase in a number of users. A minimum of 750,000 square feet and above is needed for the service providers to offer the fund.
The Definition of a Small Building:
According to the U.S. Energy Administration’s 2012 Commercial Building Energy Consumption Survey, 88% of commercial buildings are 25,000 square feet or less. The need for clear and consistent cellular and data are immense and continue to grow, but most commercial buildings fall into the “small” category. The DAS are needed for smaller buildings with these circumstances.
• The materials such as low-emissivity glass, concrete, and the metal block cellular signals.
• For the buildings where the cellular signal isn’t consistently strong enough within the coverage area.
• An inadequate signal reception is noted in some buildings within large campuses.
Presenting the feasible Alternative to DAS:
The best-suited alternative is passive DAS also known as “cellular signal boosters.” They are approved by FCC to accommodate the need of most companies. The aforementioned article suggests SureCall as the brand signal boosters. A cell phone signal booster consists of an outdoor antenna, one or more indoor antenna and a cable to connect. The outside antenna transmits the signal from the cell towers and passes them to the signal booster. The signal booster, in turn, amplifies and send the signal to the inside antenna. The inside antenna distributes the signal to all cellular devices.
By agreeing to all FCC rules and guidelines, all cellular providers approved the usage of SureCall’s line of cellular signal boosters, but it must be registered with the individual wireless providers. These boosters automatically attenuate in order to eliminate the possibility of interference with cell towers as well as to detect and correct oscillation occurrences.
Finally, SureCall is suitable for all building sizes (up to 250,000 square feet) and routing configurations. For others, there are models that boost cellular signals as well as HDTV signals along with a Wi-Fi extender.
