LTE Cat1bis with a moderate date rate eases the pain points of IoT adoption, which features eDRX and PSM. It satisfies most IoT scenarios like asset tracking, POS/POC and wearables etc., while it has a cost advantage over Cat1 devices. The deployment of Cat1bis devices in IoT applications is heavily influenced by cost, which is driven by packaging, die size, board design, and BoMs. This paper presents a universal low-cost Cat1bis transceiver SoC, which supports 3GPP specified all Cat1bis operating bands, including bands 1, 2, 3, 4, 5, 7, 8, 12, 13,18, 20, 26,
