Customer Testimonials

Using Keima tools for our national WiMAX rollout allowed us to centralize, automate, and complete RF designs for more than 20,000 sites with much fewer resources than traditional methods, and helped us achieve $21 million in savings. Other than Keima’s ability to deliver features and functionality with their tools that enables project scalability, it is really the all out and fantastic support that sets Keima apart from the rest.

The strengths and value of an engineering consulting lies within the processes, people, and tools that they utilize for their clients. One of the key decisions that TeleWorld Solutions made was in utilizing Keima Overture platform as part of our Service Delivery Model. Overture provides TeleWorld Solutions the perfect balance of price, flexibility, and capabilities to provide the high quality services to our clients that they expect. Keima is a true partner that we at TeleWorld Solutions truly appreciate.
