“The WispMon team is highly knowledgeable of the fixed wireless industry, and has a proven track record of over a decade of experience providing a popular and well regarded platform to fixed wireless operators” stated Simon Westlake, CEO of Sonar. “By combining the Sonar and WispMon development and support teams, we can now leverage our larger pool of talent to accelerate the development of new, innovative features in Sonar, as well as bringing the widely acclaimed Sonar platform to all existing WispMon customers.

A billing and OSS platform trusted by hundreds of ISPs

The Sonar billing & operational support system (OSS) software has been trusted by hundreds of ISPs worldwide since September 2015. The company recently released version 1.4 with a host of new features, including Pulse that allows automatic deduction of network topology associated with network elements managed by Sonar, with the ability to implement real time prioritization, shaping, alerting, and message delivery based on changing network conditions.

Why the WispMon acquisition matters for local and regional ISPs

“The local and regional ISP industry is moving towards a complex, multi-layered approach to service delivery, mirroring work that has been happening at the national level for some time.” continued Mr. Westlake. “Sonar’s approach to solve the service delivery and management problem for local and regional ISPs has been to integrate with as many industry leaders as possible, while also developing new, exciting features like our recent ‘Pulse’ module, which automatically determines the topology of ISP networks, and our acquisition of WispMon will accelerate our ability to continue towards our goal of providing the best, most comprehensive platform in the industry.”
