In addition, in the early days of network construction, network coverage may not be particularly perfect. For example, in China, GSM network coverage is very good, and NB-IoT will inevitably have uncovered areas in the early stages of development. If you use a chip that supports NB-IoT and GSM, the IoT terminal can use the better-performing NB-IoT in the NB-IoT area and use GSM in areas not covered by NB-IoT, that is, one product is applicable. In different scenarios.
Not only that, Qualcomm 9205 also supports larger RF from 450MHz to 2.1GHz, so an RF front-end can cover all the low- and medium-frequency bands used by the global Internet of Things, so manufacturers do not need to face separate companies like the US and Europe. The market has added support for other bands. We have seen that many competing products in the market currently only support domestic IoT bands, such as Band3, Band5, Band8, etc. If you want to support the overseas IoT band, you need to add additional chips to support it, which is just now. The problem of a module with different models. In short, the global multi-mode multi-frequency is to let a hardware support multiple RF bands around the world, so that the products are global.
