Keysight World 2018 – Internet of Things

Have you ever thought about this: In the current era of flourishing applications, in addition to traditional RF performance, the stability of the 2nd to 7th layer network is also crucial. Taking WiFi as an example, it is necessary to simulate the simultaneous connection scenarios of a large number of terminals or access points to optimize the design and performance, and it is also necessary to test the traffic in real application business scenarios. In addition, how to simulate the impact of changes in connection distance, channel changes, etc. on traffic performance.

Have you ever thought about the need for a fully controllable device that can replace the actual network and conduct accurate power consumption testing? Since most IoT applications are difficult to update due to geographical location or cost reasons, long-term operation is the key to the promotion of IoT modules, and in some cases it may even take more than 10 years. Therefore, power consumption is the most basic and important indicator of IoT terminals or modules.

Have you ever thought about this: There are two representative technologies for LPWAN: NB-IoT and LoRa. NB-IoT works on the cellular licensed frequency band, and the network is deployed and maintained by operators. In order to ensure normal communication and operation with the base station, it is necessary to effectively verify its functions before the actual deployment of the product. Although LoRa is a non-cellular network, the non-disclosure of its standard details makes it difficult to generate standard signals for verification.
