Distributed Antenna Systems, or DAS, is a small-cell wireless application that improves a wireless network and can also cause interference problems. DAS deployments have important implications for building owners, as well as for wireless carriers. It is swiftly becoming a major topic of engineering discussions as a practical solution to 3G, LTE, and 4G network penetration.

Here’s your chance to be a part of the discussion! WCAI International is sponsoring a free webinar on the DAS on Thursday, March 29, at 4 p.m. Register HERE.

Addressing the issue will be David Saab, vice president for development at Selective Site Consultants. The Overland Park, Kan., consulting company is a leading provider of services to telecommunications, development, and construction industries. LBA Group Inc. chief technical officer Chris Horne will introduce the speaker and moderate the follow-up discussion.

DAS systems solve in-building wireless coverage problems

“Site development” is the industry term for the disciplines needed to build wireless infrastructure. Today’s wireless world began with a handful of towers and rooftops and exploded with the success of the cell phone. Voice begat data, data begat broadband, and the more people who used it, the more site development activities unfolded.

But the wireless boom revealed the limitations of tower or “macro” sites. The physics of radio waves and propagation through certain building materials—along with the sheer concentration of users—are overwhelming wireless networks. This has led to the development of in-building and other Distributed Antenna Systems.

DAS is deployed inside a structure as well as in limited geographical areas, such as shopping districts and parking lots. But DAS cannot be as straightforwardly deployed as the traditional tower or rooftop systems. Walls get in the way and so do other RF emissions. Limitations on space, safety, and interoperability mean carriers must work together to create networks that provide effective mobile end-user experiences.

The problem is a small in scope but big in implications, and you can learn more about it in the webinar.

LBA provides top-down review and evaluation of DAS and small cell requirements. We specialize in relating enterprise wireless coverage needs to available technologies to aid management decision making and implementation budgeting and control. Contact 252-757-0279 or sales@lbagroup.com.
