as will the 4x4 MIMO support in the DL. However, in order for the planning to consider these inputs, it is important that a larger percentage of UEs in the area of deployment support these features. CHAPTER 1 NETWORK PLANNING Cell Sizes: Femto VS. Micro VS. Macro Table 1-6 provides a brief estimate of the cell types, their usage, range, and the transmission power level that is typically used. Table 1-6. Different Cell Types and Use Cases Cell Type Cell Range Transmission Power and Other Characteristics Macro cell 1 km to 100 kms Transmission power = 10-20 watt port. Usually an outdoor deployment (e.g., rural deployment, dense urban deployment, etc.) Micro cell 0.5 km to 1 km Typical transmission power = 4 watt port. Usually an outdoor deployment (e.g., small office deployment, stadium deployment, etc.) Femto cell ~500 m Typical transmission power = <2 watt port. Ideal for indoor deployment. LTE Performance Testing Performance testing for LTE eNodeBs can broadly be classified into four test areas: Key performance indicator (KPI) verification Traffic model-based testing Overload testing Long-duration testing To perform these tests, you must simulate traffic and generate load conditions with multiple UEs and simulate failures. Also, it is not possible to test all these cases as part of drive tests or field tests because some of these scenarios are not easy to re-create. There are many tools available in the market that specifically target performance and load testing, such as Azimuth, TM500 (Aeroflex), ERCOM, and JDSU. These tools are able to simulate multiple UEs performing different actions at the same time, and it is also possible to distribute the UEs at different distances from the cell center and simulate different fading models for these UEs (e.g., EPA, EVA, ETU, etc.). It would be ideal to perform these testings with a performance test tool and then verify a subset of these tests again as part of a drive test or field test and match the results, SO there will not be much difference between the lab results an
