Dense Air: Helping communities and carriers build secure, efficient, and inclusive networks

Dense Air is part of Sidewalk Infrastructure Partners’ CoFi platform, advancing shared broadband solutions to help close the digital divide and make connectivity more open, shared, and inclusive. Dense Air serves the United States, Europe, and Asia-Pacific with its mobile and fixed broadband services. Combining Open RAN infrastructure with Citizens Broadband Radio Service (CBRS) spectrum or licensed spectrum, Dense Air’s unique technology allows multiple network operators to securely share the same infrastructure, driving down infrastructure costs for both service providers and municipalities while delivering high-speed connectivity across use cases. Dense Air’s secure and shared approach to building wireless networks maximizes 5G network deployment speed and lowers operating costs for telecommunications operators, while also helping operators avoid large and redundant capital investments in proprietary 5G infrastructure. Dense Air’s networks deliver secure and expanded coverage for mobile operators and simultaneously enable municipal or civic uses, such as borderless classrooms for underserved students. Dense Air prioritizes building innovative public-private partnerships (P3s) to deliver its unique “carrier of carriers” neutral host small cell wireless infrastructure services and solve connectivity challenges for existing network operators by extending their mobile networks. Dense Air delivers cost-effective 4G and 5G solutions to support a range of use cases with a single secure RAN infrastructure, including enhanced mobile broadband, IoT, public safety, first responder networks, and remote learning.

RAN (Radio Access Network) interfaces that support interoperability between different vendors’ equipment encouraging innovation and offering greater network flexibility at a lower cost than the traditional closed and expensive single-vendor alternative.
Shared physical infrastructure—radios, antennas, switches—and either shared or licensed spectrum available securely to multiple carriers and service providers.
A network of tall towers that transmit low bandwidth radio signals across a multi-mile geographic radius.
A network of low-powered radios discreetly mounted on street poles, buildings, or indoors near end-user consumption that transmit high bandwidth, targeted radio signals across a radius of hundreds or thousands of feet.
Hard-to-reach network boundaries with the weakest signal strength and highest interference where demand is highest and the macro signals are poorest.
Base stations that connect with users’ LTE and 5G handsets.
