About Geeflex

Who we are ?

Beijing Geeflex Technology Co., Ltd

Beijing Geeflex Technology Co., Ltd. was established in 2013. The founders are several engineers and researchers in the field of communication and computer. In the interdisciplinary field of Software Defined Radio (SDR), we have many years of research and development experiences, and are committed to creating the most cost-effective products and promote the application.

At present, our main products are high-performance 4G/5G end-to-end simulation systems based on SDR technology. Among them, the network simulator is suitable for the development and production testing of terminal chips, modules and equipment, and has been widely used in the industry. Compared with the traditional tester, its single system has higher performance (10Gbps downlink rate) and more flexible usage (for example, it can support multi-card terminal test). The multiple UE emulator product is a cost-effective 5G base station R&D test tool, which can test applications independently, and can also be used as a good supplement for expensive traditional UE emulation.

What we can do ?

1 Standard Amarisoft Callbox and UE Simbox

As an earlist partner of Amarisoft, Geeflex can integrate and provide all Amarisoft Standard products, including Callbox and Simbox.

2 Enhanced Callbox and UE Simbox

Based on the deep understanding of Amarisoft products and various application requirements of customers, we did some further development to enhance network emulator and UE simulator.
