Leveraging its unique capabilities as a mobile operator, NTT docomo is a leading developer of cutting-edge technologies for NFC mobile payments, mobile GPS, mobile TV, intuitive mobile assistance, environmental monitoring, smart grids, C-RAN and much more.

Artiza’s Solutions for NTT docomoArtiza’s eNodeB Tester DuoSIM-A has further enhanced NTT docomo's activities for network reliability evaluation with its small footprint, low power consumption, and excellent cost performance. NTT docomo develops and evaluates multiple models of LTE eNBs according to location, cell size, and number of users. Artiza's DuoSIM has become the cornerstone that sets the quality standards of NTT docomo's comprehensive LTE eNB development through its flexible functionalities and performance. NTT docomo is currently using multiple installations of high-capacity DuoSIM LTE eNB testers.

docomo 4G

NTT docomo’s AdvancesIn March 2015 NTT docomo launched its LTE-Advanced next-generation mobile communication service featuring a Japan-best 225 Mbps maximum data-transmission speed. The use of Carrier Aggregation technology enabled docomo to achieve its ultra-high speed downlink. In 2016, docomo implemented TDD+FDD joint operation and new CA frequency combinations, including in the 3.5 GHz band, to further accelerate speeds to 375 Mbps in May. Docomo has set plans to introduce 4x4 MIMO and reach 500 Mbps before the end of Q1 2017.

Advanced C-RAN and the DuoSIM-AA unique feature of docomo's LTE-Advanced service is its introduction of Advanced C-RAN, a network architecture that combines C-RAN and Carrier Aggregation to increase radio capacity and maximum transmission speed simultaneously especially in high-traffic areas. Artiza’s DuoSIM-A eNB tester is the testbed that enabled docomo to develop and verify this technology, and is currently the only proven C-RAN test solution in the market.

NEC delivers tailored solutions in the key fields of computer, networking and electronic devices, by integrating its technical strengths in IT and Networks, and by providing advanced semiconductor solutions through NEC Electronics Corporation.

Artiza’s Solutions for NECNEC has been collaborating with Artiza Networks for LTE eNB development since September 2009. The development has been running smoothly with Artiza products, due to Artiza’s flexibility and the responsiveness of their support team. Immediate feedback to develop additional features on their testers has greatly helped NEC’s engineers in the development process.

China Mobile

Customer OverviewChina Mobile is a Chinese state-owned telecommunications company that provides mobile voice and multimedia services through its nationwide mobile telecommunications network—the largest of its kind in the world. Listed on both the NYSE and the Hong Kong stock exchange, it is the most valuable mobile telecommunications company in the world. As of June 2015, China Mobile is the world’s largest mobile phone operator with over 817 million subscribers.

Artiza’s Solutions for China MobileArtiza’s LTE eNB Tester DuoSIM won the TD-LTE load tester competition at China Mobile Communication Corporation (CMCC) held in fall 2011. CMCC has since extensively used Artiza’s LTE Testers to perform load testing on TD-LTE equipment provided by multiple Chinese and international vendors. CMCC recognizes Artiza’s load testing capability as indispensable to their testing methodology for evaluating LTE equipment, especially with broadband data traffic expected to continue growing rapidly in the coming years in the high-population cities it serves nationwide.


Customer OverviewHuawei is a leading global information and communications technology solutions provider whose products and solutions have been deployed in over 140 countries and support the communications needs of one third of the world’s population.

Artiza’s Solutions for HuaweiHuawei’s LTE eNB testing team has been relying on Artiza’s LTE eNB Testers to run their entire set of final testing environments since 2011. Ranging from basic functional tests to more complex load tests (e.g. C-plane/U-plane combined testing under heavy load conditions), Artiza LTE eNB Testers provide the complete test set required for every release.
