Sistelbanda was a Valencia-based software company with a focus on the mobile industry. It specialized in LTE small cell software solutions, software customization, and hardware design services. It was founded in 2006 and had a team composed of engineers, developers, and technical experts to create its solutions. It was stated that Sistelbanda's solutions improved the user experience of its clients' users as well as increased the profitability for its clients.
It is assumed that Sistelbanda is now closed due to the inability to reach its website and other factors. The last evidence of social media presence by the company was in November 2016 on Twitter and the page has not been updated since.
In February 2015, Sistelbanda partnered with Telefonica, a Spanish telecommunications company, to work on a project with LTE femtocell technology. The technology was intended to be used by small and medium enterprises (SMEs) in the 4G network. It was being designed to handle high voice and data traffic that often comes with SMEs.
