Taqua was a privately owned company, founded in 1998, and acquired by Sonus in 2016. Headquarted in Richardson, Texas, the company also had technology centres in Toronto (Canada) and Massachussets, USA. Developed their own softswitch and targetted replacement of expensive Class 4/5 landline telephone exchanges, winning many of the smaller US telcos. Their system architecture was centred around IP and uses SIP based switching protocols.
Entered the small cell market by acquiring Tatara in mid 2011, who had developed a standards compliant Femtocell Convergence Server for CDMA femtocells, which had been successfully deployed at Sprint and supports Airvana and Ubee-Airwalk small cells. Their portfolio was expanded to cater for 4G/LTE small cells using a common IMS/SIP core. Wi-Fi interoperability was added through a partnership with Kineto Wireless.
Taqua partner with Acme-Packet and Broadcom, amongst others, for various components of the total solution.
Commercially, Taqua offered "Femtocloud" - a "Small Cell as a Service" solution aimed at the smaller/local US mobile telcos. They host the convergence server as a managed service, reducing the cost, complexity and time to deploy CDMA small cells. Announced partnership for deployment of FemtoCloud with Cellcom, Wisconsin in 2012. This solution wasn't widely deployed elsewhere.
