Each remote connects via fiber optic cabling to a centralized headend. Each DAS is scaled to meet building occupancy and bandwidth demands.Ī DAS features strategically-placed antennas throughout an indoor venue to expand and enhance wireless connectivity. Second, they provide dedicated capacity in a building rather than sharing it with all of the subscribers covered by a cell tower. First, they deliver cellular service indoors where signals from macrocells are weak or nonexistent. Today they are often found in large office buildings, hospitals, hotels, universities, airports, stadiums, and underground transit systems.ĭAS solutions serve two essential purposes. These include distributed antenna systems, repeaters, and small cells.ĭistributed Antenna Systems (DAS) operate both indoors and outdoors. In these cases, several technologies can fill in coverage gaps. Plus, natural barriers – like hills and trees – or manufactured substances – such as concrete and glass – can block signals and degrade coverage, especially inside buildings. Often, the macrocells in a given area cannot provide adequate coverage for all of the connected devices. The coverage range of these installations may be as small as a few hundred feet. In dense urban areas, cellular equipment can also be placed on utility poles or other types of street furniture to provide service to high demand areas. Often, multiple carriers and public safety agencies will share a macrocell site to serve their subscribers and support emergency services in the coverage area. The typical coverage area for a macrocell is up to three miles. Antennas can be attached to a cell tower placed on a rooftop. The equipment reliably transmits signals to and from mobile devices in the area. These sites include antennas, a base station receiver, transmitters, GPS, and backup power. ![]() – builds outdoor cell sites, typically referred to as “macrocells,” to provide cellular coverage for their subscribers. ![]() To help you get started, SOLiD offers this primer to understand standard industry terms and wireless connectivity solutions.Įvery mobile carrier – Verizon, AT&T, T-Mobile, Sprint, etc. As competing solutions vie for attention, it can be hard to know which one is best for your property. Every in-building environment is different, with its own set of challenges. Looking to the future, an array of new mobile devices – like 5G-capable smartphones, wearables, and Internet of Things (IoT) smart devices – will also require connectivity and increase expectations for quality wireless service everywhere.įor building owners and managers, addressing this soaring demand for wireless capacity requires prompt, smart decisions. Today, everyone expects fast, reliable wireless service both indoors and outdoors, whether it’s for personal use, business applications, or to meet the needs of first responders and public safety personnel.
