Nextivity Expands Business Solutions with Release of HARMONY Private Networking Service and CEL-FI QUATRA 4000c

Intelligent cellular solutions leader provides flexible entry into private networking for manufacturing, distribution, warehousing, and healthcare industries.

Nextivity, the industry leader in intelligent cellular coverage solutions, today announced the launch of its HARMONY Private Networking service and CEL-FI QUATRA 4000c – the market’s first neutral host active DAS hybrid solution with the convergence of private cellular.

Over the past 15 years, Nextivity has evolved from a consumer business to become a hardware leader and trusted provider of enterprise cellular coverage and public safety solutions. The release of HARMONY marks the next chapter of innovation and latest product category for Nextivity, as it continues to solve wireless challenges and advance connectivity so people and business can achieve their most ambitious goals.

Enterprise industries, including manufacturing, distribution, warehousing, and healthcare, require reliability, flexibility, mobility, and security in their cellular networks to deliver improved business outcomes with IoT and workforce technologies. However, traditional commercial networks often cannot meet the indoor wireless connectivity needs for these industries. A private cellular network can address these connectivity needs, but the high cost of initial deployment has been a deterrent for many enterprises. Nextivity HARMONY Private Networking removes this barrier, enabling enterprises to deploy and utilize a private network without the risk of a multi-million-dollar investment.

Simplifying the process of adding a private network, HARMONY Private Networking is an easy-to-use, low-risk entry point into CBRS private LTE, allowing companies to benefit from specific private networking applications at a fraction of the price of other solutions. HARMONY includes all the components necessary – edge server with evolved packet core (EPC) on premise, CBRS small cell, SAS management, and SIM cards – for a private network deployment. The system can be up and running in as little as one day when paired with CEL-FI QUATRA 4000c, making it easy for businesses to implement quickly and take full advantage of the benefits private LTE offers.

“Nextivity has been making the difficult easy for a long time – first with cellular coverage, then public safety, now private networking,” said Stephen Kowal, CCO of Nextivity. “A lot of people are talking about private networking conceptually. With the launch of HARMONY and CEL-FI QUATRA 4000c, Nextivity provides a complete solution for the bulk of enterprises to capitalize on private networking at a manageable price point. Our solutions allow those responsible for delivering secure, reliable network coverage and communications as well as those responsible for improving operations and managing finance to work in harmony.”

Reliable cellular coverage is essential for any modern enterprise and is a crucial component of a comprehensive wireless strategy, regardless of whether private networking is implemented. CEL-FI QUATRA 4000c ensures dependable multi-operator connectivity by combining the industry-leading cellular coverage that QUATRA systems are known for with CBRS private networking capabilities. In addition to intelligent signal boosting for mobile network operators (MNOs) service coverage, QUATRA 4000c allows businesses to easily integrate HARMONY Private Networking into their wireless strategy and extend the service throughout the building where needed.

“An effective wireless strategy includes Wi-Fi, public cellular, private cellular, and IoT connectivity – CEL-FI QUATRA 4000c and HARMONY Private Networking solve half of this equation by providing both private and public networking options,” said Michiel Lotter, CEO of Nextivity. “With next-level connectivity offerings, we have the most comprehensive private networking solution for enterprises.”
