Sidewalk Infrastructure Partners (SIP) has reached a definitive agreement to acquire a majority stake in Dense Air. Dense Air Networks will operate within SIP’s CoFi innovation platform, which aims to make connectivity more open, shared, and inclusive through public-private partnerships (PPPs).

Dense Air builds, owns and operates secure and shared small cell networks that efficiently enhance and extend the traditional macro networks built by incumbent mobile network operators. Small cell network supports better coverage closer to the user, complementing macrocells by easing network congestion and reaching areas where macro service deteriorates.
