Small cells are getting a lot of attention as a solution to coverage and capacity challenges in buildings and urban areas. But long before small cells (femtocells, picocells, metrocells, and the like -- we’ll call them picocells for the sake of simplicity) were invented, DAS was providing pinpoint mobile coverage and capacity to buildings and outdoor areas. In many ways, DAS was the original small cell. In this article, we’ll compare pros and cons of DAS and picocells and see how they can work together to provide optimum mobile services.

DAS Pros and Cons

A DAS works by carrying a signal over fiber or CATV cable from a base station and head-end, through managed hubs, and out to remote antennas. A DAS can scale from smaller buildings to very large venues such as airports and stadiums, urban canyons, and suburban areas. Fiber-fed DAS can stretch 15 miles or more. In addition, a DAS can carry multiple frequency bands and can support multiple carriers with a single set of electronics, antennas and fiber or cable connections. Advanced DAS products can support up to 8 different frequency bands with a single set of head-end and expansion hub equipment. Also, a DAS provides consistent, uniform coverage and capacity from every antenna point, creating a blanket of coverage that eliminates cell phone handoffs.
