the device remains reachable for a mobile terminated transaction moving from connected to idle mode. The device starts the active timer when it transactions from connected to idle mode. When the active timer expires, the device moves to power-saving mode. While the device remains in power-saving mode, it is not reachable as it does not check for paging, but it is still registered with the network. The device remains in PSM until a mobile- originated transaction occurs. The PSM will significantly increase and extend the device’s battery life, increasing the DRX cycle (Discontinuous Reception) with different transaction cycles for an LTE-M device. Using Release 12 PSM with 10 minutes’ DRX cycle and a weekly transaction cycle may extend a typical 1500mAH battery’s life to more than 10 years. Main Characteristics of PSM: Enhanced power-saving mode (PSM) Efficiently turning OFF-ON modem, optimized for device-originated or scheduled applications Extended Discontinuous Reception (DRX) Longer sleep cycles optimized for delay-tolerant, device-terminated
applications Connectionless Random Access Channel (RACH) Data transmissions via a common channel for more efficient transition between states Less frequent Tracking Area Updates (TAUs) and measurements Configurable for low-to zero-mobility M2M applications Conclusion It is widely accepted that LTE will be used for nearly everything that requires a wireless connection, including M2M and IoT applications where it was once deemed too expensive and complex. LTE means more than high throughput; it offers better spectral efficiency, longevity, scalability and economic benefits for device makers and operators. The migration to LTE has already started for M2M and IoT businesses, and all connected devices, from the high-tier smart phone to the lowest utility meter or wearable device, will be LTE. LTE Category M will be on 3GPP implementation till the end of 2017, with commercial deployment in 2019. In the current scheme of deployment of 3GPP Rel-12 and Rel-13 LTE for M2M
standards, looking at the long period of integration in M2M/IoT products/ systems and regional carrier plans, it will take some time to transition and switch on toward full Machine Type Communications LTE-M support, while the LTE Category 1 will perfectly fit M2M needs in terms of complexity, price and functionality. Quectel Is Developing LTE-Cat1 Module Tailored for M2M/IoT Applications Quectel Wireless Solutions, a leading global supplier of GSM/GPRS, UMTS/ HSPA/LTE and GNSS modules, solutions and services, will launch the LTE-Cat 1 module optimized specially for M2M and IoT applications in Q2, 2016. Samples of this module will be available in Q1, 2016. Key Benefit of Quectel LTE-Cat1 Module: • Low-cost, low-power LTE connectivity optimized for broadband IoT applications • Worldwide LTE and UMTS/HSPA+ and GSM/GPRS/EDGE coverage • MIMO technology meets demands for data rate and link reliability in modem wireless communication systems • GNSS receiver available for applications requiring fast and accurate fixes in any environment • Embedded power management unit (PMU) featuring ultra-low deep sleep current consumption
