First Generation Product Experiences
NTT docomo has been introducing a number of Artiza LTE eNB Testers in the R&D center since 2009. LTE eNB wrap-around test bed for macro cell (5,040 UEs in 6 sectors of one E-UTRAN cell, shown in Figure 6) is regularly used as the ultimate testing environment in docomo. For each eNB vendor, an independent test bed was set up to finalize every release of the product file set.
Test engineers in the sites are quite satisfied with the Artiza's products functionalities, performance, and quality. And they don't believe any other tester vendors can even come close to developing the same level of quality products.
