protecting the device and data, plus trusted identities pre-integrated into the root of the TX62 during manufacturing. When needed, designers can specify an optional integrated eSIM that can simplify logistics and manufacturing processes and improve flexibility in the field through dynamic subscription updates and remote provisioning. LAS development in Arduino Portenta H7 applications is simplified using the Portenta Cat. M1/NB IoT GNSS Shield (Figure 7). The shield combines the Edge computing power of the Portenta H7 with the connectivity of the TX62 to enable the development of LAS asset tracking and remote monitoring in smart city applications as well as industrial, agriculture, utility, and other areas. The basic Portenta Cat. M1/NB IoT GNSS Shield does not include a GSM/UMTS antenna. Instead of searching for a compatible antenna, designers can use the Arduino dipole pentaband waterproof antenna.

Additional benefits of the Portenta CAT.M1/NB IoT GNSS shield include: ■ Ability to change connectivity without changing the board ■ Add positioning plus NB-IoT, CAT.M1 any Portenta-based design ■ Significantly lowered
Summary Advances in low-power and high- performance GNSS technology are factors driving the growth of LAS smart city applications. However, simply using the most energy- efficient hardware is only the starting point; it’s equally important to optimise the firmware to arrive at an optimal and energy-efficient solution. There are numerous combinations of hardware and firmware available to choose from when developing GNSS-based LAS applications and designers can turn to a variety of eval tools to speed the development process.
