Transforming Connectivity at BWI: A Next-Gen WiFi & DAS Success Story

At a modern airport, reliable wireless isn’t a bonus, it’s essential. Travelers expect fast WiFi, tenants need stable service, and operations depend on always-on connectivity.

That’s why Baltimore/Washington Thurgood Marshall International Airport (BWI) upgraded its wireless infrastructure across a huge, high-traffic footprint: 2.423 million square feet, five concourses, and 73 jet gates, serving 26.2 million passengers annually.

In 2020, Slice Wireless (SLICE Wireless Solutions) was chosen to establish, operate, and maintain BWI’s airport wide wireless program. The scope included a new WiFi system, a Distributed Antenna System (DAS), and related wireless technology services; transitioning from the previous provider.

The results are measurable. BWI’s platform now includes well over 200 access points, supporting 1,000’s of simultaneous connections, and Millions of monthly connections. Reported speeds improved dramatically—from around 2 Mbps to about 65 Mbps in most terminal areas, with select locations reaching 100 Mbps. The impact is simple: smoother streaming, faster downloads, stronger coverage, and fewer frustrating dead zones.

Just as important, the network was designed for real airport life; where needs change quickly. Using a mesh enabled approach, Slice Wireless can deploy temporary wireless for events, pop-ups, or tenant activations without compromising any standards.

The program also supports a cost recovery network model, creating over $1M in new revenue opportunities, and receiving multiple awards for Smart Infrastructure and Smart Restrooms.

Behind the scenes, disciplined planning keeps performance consistent across the campus. Best practices like wireless site surveys and RF site surveys help validate coverage and capacity, ensuring the network keeps pace as demand grows.

BWI’s upgrade shows what next generation airport connectivity should look like: fast, scalable, flexible, and built to last.
