  @Ronan-Lacroix I have a question: The min value for T3412 is only valid for the “extended” version of TAU ? Does the 1 hour apply also to the min. value of standard TAU or is it shorter? Having a min TAU of 1 hour seems to me for many use cases difficult because the devices in those use cases need to wakeup from sleeping much more often (e.g. every 10 minutes). Many many thanks for your support! Regards, Roland I

  @Stefan-de-Lange Sorry for the late answer. I have been trying with the URC logs and they confirm my suspects. Data are sent just at the beginning of the connected mode. Then a RRC inactivity timer of about 5 seconds follows. Do you know why providers are choosing in favor of longer or shorter DRX inactivity timer as well as an inactivity timer with DRX cycles?

  As roaming is more or less transparent for the device as well as backend-end server, this recommendation formulated here https://forum.iotcreators.com/topic/594/data-packet-size still applies.

  Hi, Is there a problem with the T-Mobile NBIoT network. Quite some devices having a connection with T-Mobile went offline at night between 26 and 27 April Thanks, Thanas

  Hi Artur, one of our customers have been using https://opencellid.org/ in the past for cell-id localization. Telekom is also working together with Polte which offer an IoT localization API. You can learn more here: https://iotcreators.com/en/iot-location-api/ and sign up if you want to try it. Florian

  Hi @Claude-RICHARD Welcome, happy to have you here :-). Unfortunately you can only use our UDP server with simcards from Deutsche Telekom. We can send you one, but there is another problem: we do not have NB-IoT roaming in France (yet)…

  @magnatron yes it is correct But it still possible that in some places there is no network available at all. Some operators only activated part of their networks.

  We can find this out by looking up the connection info in our network. Can you please send me the ICCID (number on the sim-card) or IMSI via DM or support@iotcreators.com? Thanks!

  The GSMA offers a “Mobile IoT Deployment Map”. You can click on a country and see various information per technology type e.g. which operator deployed that network type and even URL’s of the operators’ maps for that country (if the MNO made it available). GSMA is improving and enhancing it continuously.

  Yeap! The thief can only re-use the sim-card when he registeres his own IMEI number and used the sim with his IMEI.

  @inka-O internet.telekom is for smartphones. it won’t work for NB-IoT and the SIM cards are not allowed to use it I believe.

  @FrancoisD , Cell reselection is natively supported by the NB-IoT network, there is nothing to be done at the module level to enable this feature. Best regards, Ronan

  For NB-IoT we have an UDP adapter. So with NB-IoT you’ll need to use APN cdp.iot.t-mobile.nl which will allow you to send device data to 172.27.131.100. To retrieve the device data in your back-end/cloud server/iot platform, you’ll need to create an HTTP integration. If you use the sim-card for LTE-M or 2G, you’ll need another APN: m2m.public.nl. By doing this, the device will get a public IP address just like any other device on the open internet. This means that you can send device data directly to your own server while using LTE-M or 2G. Hope this helps!

  @lorenz Dear Lorenz, Thanks a lot for the feedback and I’m glad to see eDRX is delivering its promise on energy saving! Another tip maybe: please consider setting your preferred Periodic TAU Timer to save further energy. This can be done without setting any PSM activity timer with the CPSMS command, with a TAU-timer of up to 310 hours. To enable Long-Periodic TAU without PSM, use value “11100000” for parameter <Requested_Active-Time>. Best regards, Ronan

  @inka-O, As stated above, we will implement eDRX for LTE-M beginning of next year, but we cannot tell you exactly when right now (our current target is Q1 2021). As far as we know, most of the other European LTE-M operators haven’t yet enabled eDRX neither, but also plan to deploy it next year. eDRX does not exist in 2G, only in LTE, and deployed primarily (if not exclusively) in its Low-Power Wide-Area categories (i.e. LTE-M and NB-IoT). PSM is supported in all of DT’s LTE-M networks as well as in all of our roaming partner networks. Like eDRX, PSM has only been standardized in LTE networks and is not available for 2G. Best regards, Ronan

  Hi All, We would like: Accuracy of 3 to 5 meters latitude / longitude Correct altitude measurement(up to 1 meter, for certain use cases even more important than lat and longitude). This is for height measurements in building so that floor levels can be determined accurately We would like secured connections to the service, preferably a VPN A process that clients can be checked if they are to be trusted(we don’t want to deliver this sensitiedata to bad people with sinister plans) Adjustable frequency of positioning, higher frequency means paying more. High frequency is refresh every second(for emergencies for instance) Possibility to cross reference/compare the data with GPS data out of the field A way to determine which radio’s on which cell towers are used, this will be important if the target is moving. A service which checks the availability of the positioning service and availability of data Questions Is the data available on all networks(2G, 3G, 4G - NB-IoT/LTE-M enabled devices). My / Our assumption is that it is, as long as three cell towers/radio’s can be connected to. Are changes necessary in the firmware of cellular modules to use the service? Is the data available as a service, so do we receive aggregated data. Or do we receive lang, long and altitude plus data where the data is retrieved from(cell towers and radio’s plus the signal strength data which comes with it? Is the service strictly available on the network of T-Mobile? Or is the data still available when roaming takes place to other networks? How reliable is the service, especially on moving targets, when roaming is necessary? How accurate is the service? Or how accurate can you get? To which height is the service still available(we have gone up to 2,5 kilometers on NB-IoT). Ewout Karel has done about 300 - 500 meters on a relatively fast moving target
