Why go for low bandwidth when there is high bandwidth 4G (even 5G) network available?
既然有高頻寬的4G(甚至5G)網路，為何選擇使用低頻寬網路？
There are very different use cases for such a low bandwidth network. Low bandwidth network’s main application is in sensing modules for data collection and analytics which are measured in bytes. This provides cost savings up to 90% as compared to the more expensive 4G network.
此種低頻寬網路的使用情境非常不同。低頻寬網路主要應用於感測模組，用來收集數據和分析，以位元組(byte)為單位。比起費用昂貴的4G網路，可節省高達90%的成本。
