Cel-Fi by Nextivity

What Cel-Fi by Nextivity does

Nextivity, Inc., operating commercially as Cel-Fi by Nextivity, is a privately held San Diego-headquartered company founded in 2006 that designs and distributes in-building cellular signal boosters and adjacent connectivity hardware, software, and managed services. The company's portfolio is organized under three brand lines — CEL-FI for cellular coverage (QUATRA enterprise systems, GO mobile boosters, ROAM and CONNECT products), SHIELD for critical communications and HPUE (SOLO, EXTEND, MegaFi 2 Global), and WAVE for management software and edge services (Private 5G, IoT sensor networks, panic/call button and gunshot detection services). The underlying technology, IntelliBoost®, is described as a proprietary signal amplification architecture engineered specifically for in-building cellular coverage and extended in 2025 with native LEO Direct to Device support for non-line-of-sight satellite connectivity.

Products are sold across more than 100 countries and are certified as unconditionally network-safe for use by over 200 mobile network operators, with additional TAA and FAA compliance for U.S. federal and aviation-adjacent deployments. Revenue is generated through three streams: hardware sales (the largest visible line, channeled through direct enterprise sales, certified DAS installers, and regional distributors), DAS-as-a-Service managed coverage offerings, and recurring/subscription WAVE platform and edge services including private LTE/5G networking, IoT sensor networks, panic button services, and gunshot detection. Customer concentration is spread across vertical segments including data centers, manufacturing and warehousing, healthcare and aged care, education, hospitality, office and property management, retail and grocery, multi-tenant residential, vehicles and boats, public safety/FirstNet Band 14, and mobile network operators. Go-to-market combines enterprise field sales for complex deployments with a structured channel partner network and ten dedicated regional country websites spanning North America, Europe, the Nordics, the Middle East, Africa, and Oceania.
