About Us

Who We Are

Artiza Networks is the leader in 3G, 4G, and 5G radio access network (RAN) and core network (CN) node testing. For over 20 years, Artiza has collaborated with the industry’s top vendors and operators in testing the RAN and core network nodes of the world’s most advanced mobile networks. We teamed with a major vendor and operator in Japan to perform the first ever experimental trial of LTE technologies. Since then, our high-density load testers have dominated the Japanese market, and set the standards for our global partners.

Our extensive engineering resources include PCB and FPGA/DSP development in wired and baseband formats, as well as highly skilled firmware and software engineers. Artiza meets the full range of our customers' needs through our innovative, in-house development of products and solutions, combined with our award-winning customer support and a sales force versed in mobile network technology.

We are proud of our world-class line of testing solutions, which have continued to lead the market from development and early demonstrations of 4G through the implementation and rollout of 5G technologies.
