In this presentation you will learn about all the different possible location features of the nRF9160. You will learn about GPS tracking (A-GPS/P-GPS); LTE location tracking (Single/multicell) and you will also see how newly introduced location services from nRF Cloud can open new opportunities and save even more power consumption for your application. You will also get updated around new features in both the hardware and the software side of the nRF9160 that will help you achieve the longest possible battery life in an Asset tracking application. LTE-M and NB-IoT enable everything to be connected to the Internet. Learn how the nRF9160 SiP realizes this and makes it possible to build very small devices with many years of battery life.
During this event, attendees will have a chance to win one of five Nordic Thingy:91s for asking interesting questions about the Nordic Thingy:91, a multi-sensor prototyping platform aimed at cellular applications. The Thingy:91 is based on the nRF9160 System-in-Package (SiP), with LTE-M, NB-IoT, and GPS connectivity. It is ideal for creating proof-of-concept (PoC) projects, demos, and initial prototypes in the cellular IoT development phase.

Q&A Session:
What is the accuracy of the GPS?
GPS periodic tracking 5m, continous tracking 3m (open sky conditions)
Can you use energy harvesting to power the nRF9160?
Absolutely, the nRF9160 is best in class in low power and is very suited to be combined with energy harvesting to extend battery life or even making the application energy autonomus.
How long can a battery last for a cellular iot product?
This is very application dependable and how often you send/recieve data over the network. We have a Power optimization guide that can guide customers to optimize their applications: http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/app_power_opt.html
Can you run machine learning code on nRF9160?
Absolutely, We also have a tight integration with Edge Impulse studio with several Samples in our nRF Connect SDK that can help you speed up development. nRF Machine Learning application: http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/machine_learning/README.html
Is this module capable of handling robotics based applications like Drones?
Sure you could use the nRF9160 in drones. I would however recommend using an external high accuracy GPS module since that is usually required on Drone applications
I am not sure which methods are used by nRF9160 for indor accurate positioning, Is it AoA, AoD and RSSI based methods like in Bluetooth or something else?
The nRF9160 can only use Single cell and Multicell location inside buildings. For more accurate positioning we recommend including e.g. nRF52 or nRF53 chip into the design and utilize AoA/AoD positioning or other indoor positioning techniques.
Do this module's SDK has support and compatibility for Linux OS?
Our nRF Connect SDK is supported on Linux, Microsoft and MacOS.
Martin, can you elaborate a little bit more on VSCode integration?
More information found here: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf-connect-for-visual-studio-code-preview
Are there plans to comply with the regulations in other countries in the LATAM region such as Colombia, Argentina, Peru, Chile or Ecuador?
Columbia has LTE-M, NB-IoT support. Argentina has LTE-M and NB-IoT support. For more details see: https://www.gsma.com/iot/deployment-map/
Usually using communication protocols like mqtt, http along with TLS reduce performance of the hardware. considering this device is a memory constrained one, do you have any benchmark on the performance of the device under various cryptographic methods (hashes, keys)?
We have dedicated HW peripherals to speed up cryptograpic methods. ARM Trustzone CryptoCell 310 - https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf9160%2Fcryptocell.html&cp=2_0_0_5_0 We also provide a lot of cryptograpic samples in our nRF Connect SDK so it is possible for customers to benchmark and test out the performance them selves. Samples: http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/samples_crypto.html
Can it be woken up over the air to start running a position fix to report its location?
Absolutely. E.g. The modem can be in RRC IDLE mode and be running eDRX intervals checking the network for any wake up signals. More details here: https://www.nordicsemi.com/Products/Low-power-cellular-IoT/What-is-cellular-IoT?lang=en#infotabs
Is there a good way to work out what coverage there is for a country (e.g. UK) and what carrier would be suitable?
Recommendation is to contact the carriers themselves. Many carriers provide online coverage maps. Another suggestion is to contact your Reginal Sales Manager (RSM), and if you do not know who that is you can reach out to us on: https://devzone.nordicsemi.com/
Can you cover briefly how encasement impacts signal strength and accuracy? nRF Cloud provides services to update Assisted GPS data?
If the encasement impacts the GPS signal strength you can expect longer TTFF for the GPS to actually get a fix from the surrounding satellites. The more sattelites, the better accuracy. You can also configure in the FW to trade off accuracy with faster TTFF, which also impacts power consumption. So for GPS spesifically we recommend great antenna design to have the best possible starting point -> we have a White paper on this: https://infocenter.nordicsemi.com/topic/nwp_033/WP/nwp_033/nwp_033_intro.html
nRF Cloud provides services to update Assisted GPS data? If there is any cost associated with that service? Does A-GPS data depend on the location of the device or is it valid worldwide?
nRF Cloud provides location services and Assisted GPS is one of the features we provide. More information here: https://www.nordicsemi.com/Products/Cloud-services#infotabs There is a cost for this service, but this is very competitive compared to similar services on the market, and I recommend to reach out to your local Reginal Sales Manager to discuss more details around this. The Assisted GPS data can be recieved all around the world.
Why downloded GPS data helps for fast position fix for nRF9160?
Assisted GPS helps faster TTFF since you download the sattelite data over the LTE network (much faster) than the Sattelites themselves (very slow). That means that you do not need to have the GPS on for a long time to acuire a fix. We are talking minutes compared to seconds when using A-GPS. This is a huge power saver.
Could the thingy91 receive RTK corrections through some NTRIP server?
We do not support this feature at the moment.
Can I use this module for tinyml?
Yes. We also have a tight integration with Edge Impulse studio with several Samples in our nRF Connect SDK that can help you speed up development. nRF Machine Learning application: http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/machine_learning/README.html
Is nrf9160 required external wired antenna for LTE or GPS or it can run smoothly with patch antenna on PCB too?
The nRF9160 only require a single 50 Ω antenna interface. I would recommend checking out our nRF9160 DK and our Thingy:91 and the reference design for these products on how you can desing this on your product. We also have a white paper around this: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fnwp_033%2FWP%2Fnwp_033%2Fnwp_033_intro.html&cp=2_0_7_4
Is it possible to use the nRF9160 SiP in wearable devices used in healthcare?
Yes, it should be possible to use the nRF9160 on wearable devices in health care.
Are you planning to release a multi-core version of the nRF9160 SiP e.g. with several Cortex-M33 cores or with an additional energy-saving CM0%2B or CM23 core?
Roadmap question. Please contact your RSM
Can we use this at negative temperature environment such as cold storage warehouses.
Yes that is possible. The nRF9160 supports operating temperatures between -40 to 80 Celcius
What about the maximum temperature range for the nrf9160?
The nRF9160 supports operating temperatures between -40 to 80 Celcius.
what kind of security component this do platform provide exclude sim?
The nRF9160 supports ARM
Trustzone and ARM Cryptocell 310 on the MCU side with the addition of support for Trusted firmware-M. Please see our specification: https://infocenter.nordicsemi.com/index.jsp? topic=%2Fps_nrf9160%2FnRF9160_html5_keyfeatures.html&cp=2_0_0. The modem also has its secure elemements for certification storage and DTLS/TLS support.
is nrf9160 required open to sky area to give it's GPS position??
A GPS antenna is recommended to be in open sky conditions for best performance. However it is possible to acuire GPS fixes in "urban canyons", but you will not get a GPS fix inside a building for example.
What is the minimum current consumed by the nRF9160 in deep sleep mode?
1,4µA : MCU off, modem off, no RAM retention, wake on GPIO and reset. See: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf9160%2F_tmp%2Falta.nRF9160%2Fautodita%2FCURRENT%2Fparameters.id_current_sleep.html
Does it support asset tracking that travels across the sea..does it support global cellular connection?
The nRF9160 supports global cellular connections. As long as the device is close enough to communicate with a basestation, then travels across the sea is no issue.
What is the best PCB antenna for GPS?
Please check out our White Paper: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fnwp_033%2FWP%2Fnwp_033%2Fnwp_033_intro.html&cp=2_0_7_4
Is the intent to switch to VS code instead of Segger Embedded Studio?
We will still support Segger Embedded Studio IDE, but our extension with VS code has been built from the ground up to be tightly integrated with nRF Connect SDK. We provide the options so that developers can find out what suits them best.
What is the maximum vibration ratings of the device?
Please ask your question on https://devzone.nordicsemi.com/
What is the maximum output power level of nRF9160?
Max output power is +23dBm
Is the Nordic nRF9160 is only suitable for IoT or It can also capable of being deployed in robotic based application? Since I'm impressed with the specs and planning to deploy it in robotics?
The nRF9160 is flexible and can absolutely be used in robotics.
Do you have BLE support version board with this modem and nRF9160?
The nRF9160 Development kit has the nRF52840 on board and also the Thingy:91. This works as a board controller, but can also be used to communicate over Bluetooth LE. We have a gateway sample in nRF Connect SDK that showcases this functionality.
How does the nRF9160 compare to nRF52/nRF53 besides the RF capabilities in terms of Hardware and Software?
I recommend checking out this Product summary: https://www.nordicsemi.com/-/media/Publications/WQ-Product-guide/Wireless-Q---Q1---Product-Guide.pdf?la=en&hash=55195302B5331ECA0F7D841B58D7F97DCC945F26 on the Sotware side nRF Connect SDK is used on those devices. For working with nRF9160 you would of course use cellular spesific drivers to e.g. Get connected to the network. This is automatically handled when you build for the different SoC or SiPs.
